1.1 Intended use

Your WATERKOTTE heat pump of the Basic Line series is used for space

heating and cooling, and heating of domestic water.

An outdoor module, which is coupled to a heat source (air) that is available

year-round, serves as heat generator.

Project planning of the heat source system must be performed in compli-

ance with the technical information provided by WATERKOTTE for layout of

heat source systems. Heat pump shall only be turned on after the refriger-

ant connections are completely charged, and the other hydraulic circuits

are completely charged and vented, and all electrical connections are

properly completed.

Commissioning may only be carried out by trained professionals. Damages

caused by non-compliance with above mentioned items are not covered by

the warranty (see enclosed Exclusion of Warranty).

1.2 Basic safety precautions

1.2.1 Keep information available

In addition to the operating manual, also furnish operating instructions in

terms of Labour Protection Law and Work Equipment ordinance. Keep all

safety and operating signs on the heat pump in fully legible condition at all

times. Replace damaged or illegible signs immediately.

(oil sump heater active).

Check heating circuit temperature: Temperature heating circuit below

16 °C.

Safety

21.10.2015 6 / 60


1.2.3 Environmental protection

Observe the regulations regarding waste avoidance and proper waste

recycling or disposal when performing any kind of work on and with the

heat pump.

Ensure that particularly during installation and maintenance work, as well

as when placing out of operation, groundwater pollutants such as

grease, oils, refrigerants, solvent-containing cleaning fluids, etc. do not

contaminate the ground or enter into the sewer system!

These substances must be collected, stored, transported, and disposed

of in suitable containers.

1.2.4 Modifications and repairs on the heat pump

For safety reasons, no unauthorised modifications shall be performed on

the heat pump.

Thus, all intended modifications are subject to written approval by

WATERKOTTE.

Use only original WATERKOTTE spare parts.

Original parts are specifically designed for your heat pump. Externally pro-

cured parts provide no guarantee that they are designed and manufactured

in compliance with relevant usage and safety requirements.

Parts and special equipment not delivered by WATERKOTTE are not ap-

proved for use on the heat pump.

1.3 Hazards

Observe the following points to avoid life-threatening injuries and damages

to the heat pump during operation:

Risk of death by electric shock!

Do not use water or other liquids to clean the system!

Keep all electrical supply modules locked at all times!

Any work on the electrical equipment of the heat pump shall only be per-

formed by professional electricians!

Safety

21.10.2015 7 / 60


Leaking refrigerant can result in severe personal injuries (suffocation or hy-

pothermia)!

Avoid direct contact with refrigerant!

When selecting the installation site, observe the minimum volume under

consideration of the refrigerant applied (as per EN 378-1).

Risk of burns!

During operation, surface temperatures (compressor and pressure line) can

climb above 100 °C or drop below 0 °C.

Do not remove housing cover during operation!

Allow heat pump to cool down before removing cover.

Risk of injury!

Risk of chemical burns when skin comes in direct contact with lubricant

leak.

Wear suitable clothing when performing maintenance work on the heat

pump!

Do not put your fingers or others into the fan, or evaporator.

The inside parts of the heat pump may run at high speed or high tempera-

ture, they could cause serious injury. Do not remove the grills on the fan

outlet and top cover.

The hot water probable need to mix with cold water for terminal usage, too

hot water (over 50 °C in the heating module may cause injury.

The installation height of power supply should be over 1.8m, if any water

may spatter, the module can be safe from water.

Electrostatic charge!

Electronic components can be damaged by electrostatic processes.

Ground yourself before touching electronic components.

Risk of total loss!

Repeated restart of the heat pump can result in total loss! In case of heat

pump failure, an inspection by qualified and authorised personnel must be

performed before restart.

Safety

1.4 Operator's duty of care

Your WATERKOTTE heat pump has been designed and built on the basis

of a risk analysis and after careful selection of standards to be observed.

Thus, your heat pump is state-of-the-art and provides for maximum safety.

In practice, however, this safety can only be ensured by taking all necessary

measures. As operator of the heat pump it is your responsibility to plan

these measures and oversee their implementation.

You must ensure that:

The heat pump is only used as intended (see also chapter 1.1, "Intended use").

The heat pump is only operated in perfect, fully functional condition and safety devices are checked regularly to ensure that they are working properly.

The operating manual is available in perfect condition at the heat pump at all times.

The heat pump is operated, maintained and repaired only by adequately qualified and authorised personnel.

None of the safety and warning notices on the heat pump are removed or damaged.

3 Components and installation

3.1 Heating system Basic Line Ai1 Air BS 7010 / BS 7006

The newly developed heating system was designed as a compact air

source heat pump for outdoor installation. It is suitable for heating and

cooling low-energy buildings.

Thanks to the inverter-controlled compressor, the Basic Line Ai1 Air and BS

7010 operate extremely energy-efficiently. Due to the infinitely variable

adjustment of the power it impresses with high performance. Even at

outdoor temperatures of -15 °C, flow temperatures of 55° C are possible

The outdoor module contains all the heat pump technology (nicht der not

the condenser). The control moduel with the tank (Ai1 Air) or the hydraulic

module BS Hyd 5010 are installed in the building.

3.2 Structure and control

Complete hot water heating system with integrated central hot water supply

(option), consisting of: heat generator (heat pump), regulation and electrical

control, complete electrics and control system, semi-graphic display.

3.2.1 Electronic heat pump control

The heat pump control is included in the delivery scope of the

WATERKOTTE heat pump. Use in other than

WATERKOTTE heat pumps will void any warranty claim.

Info: Technical details, operation and warning messages (see Operating

manual for heat pump control).

The control is used to control and monitor heating systems that are operat-

ed with WATERKOTTE compact heat pumps according to technical guide-

lines of WATERKOTTE Wärmepumpen GmbH. All tasks to do with control

are fulfilled (depending on the external temperature, control, monitoring,

self-diagnosis, saving of data in case of breakdown, etc.

WATERKOTTE explicitly states that function warranty will become void if

used on systems not approved by WATERKOTTE. Any liability for conse-

quential damages due to incorrect function within these systems shall be

explicitly excluded.

Transport to installation site

21.10.2015 12 / 60


4 Transport to installation site

Modules of the Basic Line 7010 series are delivered ready-to-connect with

metal cladding. The Basic Line Ai1 Air / Basic Line 7010 are delivered ready

for connection.

Since the heat pump module weighs 120 kg or more, for instance, at least

two people are required for transport.

The devices are mounted on top of each other only at the installation site.

During transport it must be ensured that appropriate means of transport are

used (lift truck, transport rollers, handcart).

It is crucial that the heat pump is transported upright!

Transport in tilted position (45°) is permitted only temporarily during inser-

tion. Horizontal transport results in oil displacement in compressor and can

cause damage to the heat pump during start-up.

After carton is removed or opened it is not permitted to tilt the module by

applying pressure to the pipelines or housing enclosure; this could result in

bent housing parts and pipelines.

4.1 Environmental conditions for installation (indoor module)

The room must be dry. Room temperature should be between +5 °C and

+25 °C.

5 Installation and connection

5.1 Installation and connection of indoor unit

To make hydraulic connections, you must use the supplied material (con-

necting lines and gaskets).

During assembly of connecting lines, use an according tool as brace to

prevent damage to the heat distribution station.

Installation of the indoor unit must be performed on a flat and horizontal

surface.

Wall clearance (free space) in front: at least 1000 mm.

Due to the connections on the rear of the unit, the mounting distance to

the wall (rear, right side, left side) must be selected in such a way that

access is ensured in case of repairs.

Recommendation for good service accessibility: Wall clearance (free

space), left, right 400 mm. Wall clearance rear at least

300 mm.

Figure 1: Recommendation - wall clearance for installation

5.2 Environmental conditions for installation

When selecting the installation site, observe the minimum volume under

consideration of the refrigerant applied (as per EN 378-1).

The room must be dry. Room temperature should be between +5 °C and

+25 °C. To facilitate maintenance, the use of a base plate is recommended.

To compensate for minor unevenness, we recommend use of an approx.

10 mm thick rubber mat.

5.7 Installation of cover and cladding panels

To prevent transport damage, the cover, front and side panels of the heat

pump are enclosed separately.

After establishing all connections, mount them to the required positions (in-

sert and press).

5.8 Disassembly of cladding panels

The heat pump is provided with a disassembly tool. Use this tool to remove

the cladding panels to prevent damage.

Procedure:

Keep enough distance with the disassembly tool to the upper/lower

panel edge so as not to damage the retaining bolt (see figure).

The disassembly tool is manually driven into the gap between the front

and side panel with moderate force.

5.9 Disassembly of cover and cladding panels (outdoor module)

Cover and cladding panels are fixed with screws. In the case of a disas-

sembly the screws must be removed with an appropriate screwdriver.

Installation and connection of the outdoor module

21.10.2015 19 / 60


6 Installation and connection of the outdoor module

6.1 Selecting a location for outdoor module

Select a location permitting easy wiring and pipe access to the power

source and indoor module.

Avoid locations exposed to direct sunlight / other heat sources.

Select a location from which noise emitted by the module will not incon-

venience neighbours.

Avoid locations where combustible gases may leak, be produced, flow /

accumulate.

Please note that water may drain from module during operation. Ensure

unobstructed condensation drain.

Select a level location that can handle the weight and vibration of the

module.

Avoid locations where the module could be covered by snow. To pre-

vent snow from blocking / blowing against the air intake in regions sub-

ject to heavy snowfall, special precautions are required (selecting a

higher installation location / installing a protective cover in front of the air

intake). This can reduce airflow and cause malfunctions.

Avoid locations exposed to oil, steam, or sulphuric gas.

To ensure stability, we recommend the use of two concrete brackets in

combination with a gravel bed for condensed water drainage.

Select an installation site where the module is largely protected from for-

eign objects (leaves, etc.). In this connection observe the recommenda-

tions in chapter Maintenance and inspection.

Select an installation site where no foreign material (leaves, etc.) get into

the module.

Do not exceed permissible line length between indoor and outdoor

module.

Risk of injury!

When carrying the module at the bottom there is a risk of crushing the

hands / fingers.


21.10.2015 20 / 60


6.2 Clearance for ventilation and operation

When installing outdoor module on a rooftop / other location unprotected

from the wind, align air outlet opening in such a way that it is not directly

exposed to strong winds. Strong wind blowing directly into the air outlet

opening may impede normal airflow and thus cause malfunctions.

Precautions against strong winds can be seen in the following examples:

Align air outlet to nearest wall with a distance of about 50 cm.

Air guide: Position the module in such a way that the air discharged

from the air outlet is guided perpendicular to the direction from which

seasonal strong winds usually blow.

6.3 Installation in base plate or on the wall

Secure the base of the module firmly with four M10 screws to a proper

base plate (screws and nuts are not included in delivery). Please note:

Connection directions: The connection (piping and wiring) is performed

from below.

Ensure that water can drain off during defrosting. This can be accom-

plished by excavating the ground.

The installation height depends on the climate conditions at the site. In-

stall the module at a height that takes possible flooding or heavy snow

into account, but at least about 40 cm to 60 cm above the ground to al-

low unobstructed drainage of condensation. This ensures trouble-free

operation even in case of snow.

Note: Ice formation can occur particularly during the cold season. In ex-

treme cases, this can block the fans. Remedial action: Ensure unob-

structed drainage of melted water and remove excessive ice build up

below the module manually if necessary.

Figure 6: Securing in base plate

WATERKOTTE GmbH offers a wall mounting set.

Ensure that the melted water can drain off. Ensure that the entire drain is

frost-free to prevent freezing in the winter. For this purpose, a trace

heating could be applied.

6.4 Installation and space requirement

Check the figures to determine space requirement:

1. In front of wall, air outlet clear in front, flow obstacle in rear

2. In front of wall with roof, air outlet clear in front, flow obstacles in

rear and top

3. In recess: Flow obstacle in rear and on both sides

4. In front of wall, air outlet toward wall; flow obstacle in front.

5. Between two walls, air outlet toward wall, sides clear: Flow obsta-

cle in front and rear.

6. In recess with roof, air outlet clear in front, flow obstacle at rear, on

both sides and above.

Figure 7: Space requirement and minimum distances for installation

Connection lines

21.10.2015 22 / 60


7 Connection lines

Using a hydraulic station you have to create a pipeline connection between

outdoor module and hydraulic station. It is equipped with a water fill anti-

freeze mixture, the concentration depends on the geographical location.

During assembly of connecting lines, use an according tool as brace to

prevent damage.

7.1 Refrigerant charge and additional charge

The outdoor modules come fully charged with refrigerant R410A from the

factory, allowing tube lengths (one way) up to 5 m without requiring addi-

tional charging. If tube lengths are less than 5 m, the charge in the outdoor

module is sufficient. In new modules, excess refrigerant must not be

drained. However, to optimise the module we recommend individual ad-

justment of refrigerant quantity to total volume (refer to table).

The outdoor module shall not exceed 3 m higher or 7 m deep stand

out as the indoor module.

If line length exceeds 5 m, charge module with additional R410A re-

frigerant.

Please note:

The line length of 15 m (one way) may only be exceeded if the hot

water temperature is limited to 47.5 ° C! This shall be applied to the

basic settings of the controller.

The heating water temperature in heating mode has to be limited to

50 ° C!

Please note:

Do not exceed permissible line length LMAX (20 m)!

If the maximum difference in height is achieved of 3 m, an oil trap at 1.5 m

has to be provided.

Connection lines

21.10.2015 23 / 60


7.2 Oil traps

To ensure the permanent oil flow in the 16 mm line, it is necessary, in criti-

cal installation conditions, to provide oil traps in the suction line.

A vertical line running 16 mm requires:

at a cable length of 1.5 m, a centrally integrated oil trap

at a cable length of more than 1.5 m - Oil traps have to be installed cen-

trally every 1.5 m

If the 16 mm line running in the direction of flow with constant slope and a

length of more than 6 m, oil traps have to be installed every 6 m.

7.3 Insulation

For refrigerant line we recommend the use of pre-insulated original

WATERKOTTE double-copper tube rings 10 / 16 x 1.0 mm (Z16956) and

matching screw clamps (Z16957).

Recommendation:

Note: To prevent heat loss it is recommended to insulate the refrigerant

pipes separately. Note the national technical regulations (Germany: EnEV or

7.3.1 Tube airtight testing method (recommended procedure), test equipment nitrogen

Make sure that stop valves A and B are closed, and do not open them.

Connect the testing tools (stop valve A).

Add pressure to the refrigerant lines through the service port C of the liquid

stop valve A.

Do not increase pressure to the specified value at once, but rather

gradually:

1. Pressurise to 0.5 MPa (5 bar), wait five minutes, and make sure

that pressure does not drop.

2. Pressurise to 1.5 MPa (15 bar), wait five minutes, and make sure

that pressure does not drop.

3. Pressurise to 4,2 MPa (42 bar) (max. working pressure) and meas-

ure ambient temperature and refrigerant pressure.

4. If specified pressure is maintained for one day and does not drop,

the tubes have passed the test and there are no leaks.

5. If the ambient temperature changes by 1 °C, the pressure will

change by about 0.01 MPa (0.1 bar). Make the necessary correc-

tions.

6. If the pressure drops during steps (2) or (3), a gas leak exists. Look

for the source of the gas leak.

8 Refrigerant

8.1 Requirements on handling of R410A refrigerant

Ensure that work on air conditioning equipment is only performed by quali-

fied persons. Qualified persons are those who can show that they have

completed technical / vocational training in connection with an approved

advanced training course according to the Ozone Layer Regulation. Com-

pleted training of air conditioning systems or air conditioning technology is

also considered proof of qualification. Ensure that inspections on refrigera-

tion equipment, which require contact with the refrigeration circuit, are only

performed by trained operating personnel. Instructions must be provided by

qualified persons (these regulations can vary within the EC, hence follow the

laws and regulations of the respective country).

8.2 Safety guidelines for the handling of refrigerants

The following safety guidelines must be observed:

Always wear protective goggles and protective gloves!

At normal atmospheric pressure and ambient temperatures, liquid re-

frigerant evaporates so rapidly that it may cause tissue freezing (risk of

going blind) in case of skin /eye contact.

Should the refrigerant contact the skin, flush the affected area repeated-

ly with plenty of cold water. Do not rub the eyes! Visit a doctor immedia-

tely!

Ensure proper ventilation of workplace when working on refrigerant cir-

cuit. Inhaling high concentrations of gaseous refrigerants may cause diz-

ziness and suffocation sensations.

Never perform work on refrigerant circuits in work pits. The gaseous re-

frigerant is heavier than air. Thus, a high concentration could accumulate

in the pit.

Do not smoke! Burning cigarettes can cause the refrigerant to decom-

pose into toxic substances.

Keep refrigerant away from open flames / hot metal. Poisonous gases

could be released.

Never vent refrigerants into the atmosphere. As soon as you open the

refrigerant container / the air conditioning system, the content escapes

at high pressure. Pressure level depends on temperature. The higher the

temperature, the higher the pressure.

Avoid exposure of system components to heat. Otherwise, drain module

first.

When removing the service hoses, do not point connections toward

yourself. Residual refrigerant could escape.

Never change factory setting of adjustment screw on expansion valve.

Refrigerant

21.10.2015 29 / 60


8.3 Charging refrigerant circuit

Requirements:

Refrigerant line connections between outdoor and indoor module have

been established.

Tube airtight test has been performed (pressure test).

The outdoor module is fully charged with (R410A) refrigerant (in factory).

Procedure:

1. Connect vacuum pump to indoor module (Schrader valve, opens

automatically).

2. Start vacuum pump

3. When using a high-performance vacuum pump, the required vacuum

is generated after 70 minutes (-101 kPa / 5 torr).

4. Close the valve of the connection tube of the vacuum pump.

5. Open the two valves (1 a. 2) on the indoor module. The refrigerant flows

into the entire system.

6. Disconnect the tube of the vacuum pump.

Refrigerant

21.10.2015 30 / 60


How to open valves:

- Remove both protective caps.

- Open the valve completely by using an allen wrench.

Note: The ball shut-off valves are permanently opened only at time of

commissioning.

7. After both valves are fully open, attach protective caps again and tighten

(20 - 25 Nm).

Note: Refrigerant could escape if protective caps are left off.

Also make sure that the corresponding washers are screwed into the pro-

tective caps again.

8.4 Mounting (heating /domestic water side)

The installation of the heating system (flow/return)) and hot / cold water is to

be performed on the basis of the connection diagrams.

The specifications of current drinking water regulations must be observed.

Antifreeze has to be ensured for all pipes and fittings.

9 Electrical work

Before carrying out electrical work:


Any work on the electrical equipment of the heat pump shall only be per-

formed by professional electricians!


Install circuit breakers for personal protection.

For the power lines, use standard cables of sufficient capacity. Other-

wise there is a risk of short circuits, overheating / fire.

When installing power lines, do not apply tension to the cables. Loosen-

ing connections pose a risk of cables slipping from terminals / breaking;

this can result in overheating / fire.

Master switch on module (beside touch screen): If master switch is acti-

vated (switch is lit), the indoor and outdoor module are ready for opera-

tion.

The exterior temperature sensor is connected to terminals 5o / 5u.

The external disconnection is optionally connected to terminals 49/50.

The electrical disconnection of the outdoor module can take place from

the indoor module (service purposes).

Attention: However, voltage supply of the 3 feed lines- heating element,

compressor, control voltage, is applied to the main terminals/ relays of the

device!

Should it be necessary, disconnect all feed lines from the house fuse

box.

21.10.2015 32 / 60


9.1 Electrical connection outdoor module

To connect the outdoor module, the cover of the right side of the module

has to be removed.

Refer to the connection diagramms!

Neutral conductor must be connected too.

Failure to observe: results in destruction of circuit board on outdoor mod-

ule.

9.1.1 Cable cross sections/types

All cable cross sections/types must be specified on site by a professional

electrician, in compliance with applicable DIN standards. Use a shielded

cable for the BUS.

9.2 Electrical connection (indoor module) (hydraulic station / control module)

The electrical connection is performed on the terminal of the indoor module.

Follow the wiring diagram.

9.2.1 Installing external wall sensor

Install external sensor (included in delivery) always vertically (even if tempo-

rary), with cable entry pointing downward. Next, screw connection must be

tightened enough to allow sealing insertion of cable and to prevent water

from entering the housing.

When performing temporary installation, sensor might have to be mounted

on board, which is fastened to wall using a steel nail.

To prevent transport damages, front and side panels of heat distribution

station are separately enclosed.

After all connections are completed, install plates at specified positions (in-

sert and press)

9.2.2 Power supply- Heating element

The power supply (230 V or 400 V) is selectable. The power supply is de-

fined by linking the terminals on the control board.

9.2.3 Heating element - thermostat setting

The thermostat of the heating element is permanently set on 75 °C. Con-

nection and disconnection takes place via the heat pump controller. The

electric resistance heater has a safety temperature limiter. In case of trigger-

ing, it must be reset manually. To reset use the button on the bottom of the

safety temperature limiter (under the cap).

Commissioning

21.10.2015 41 / 60


10 Commissioning

During commissioning of machine, anticipate the following specific risks.

Risk of total loss!

Faulty connections can cause unexpected startup of machine / uncon-

trolled machine operation.

Mix up of connections causes motor to run in wrong direction; this could

damage the machine.

Incorrectly wired connections can destroy electrical / electronic compo-

nents.

Electrostatic processes / power failure can pose a risk for electronic com-

ponents and also result in software errors.

To avoid damage to machine / injuries during commissioning of machine,

the following points must be observed:

Commissioning of machine shall only be performed by qualified persons, in

compliance with safety instructions.

Activate all safety devices and emergency-stop switches prior to commis-

sioning.

Check motor for correct direction of rotation prior to commissioning.

Also read chapter 1.2.

10.1 Pre-startup checks

Before starting machine, check first the requirements according to the fol-

lowing checklist.

All electrical feed lines in the corresponding cross-sections are wired to

the terminals, as per connection plan. The BUS cable is shielded.

The main switch is in "OFF" position.

The fuses in the fuse box are in compliance with the specifications in

the wiring diagram (circuit breaker, switch, type C for compressor feed

line!).

The hydraulic connections for heat source, space heating and domes-

tic water are connected.

The ball shut-off valves on the refrigerant lines are open.

The following positions must also be checked.

The gas stop valve as well as the liquid stop valve are fully open.

Before operation, check if all plates, fuses and other protective devices

are properly installed. Components that are rotating, hot / under high

voltage can cause injuries.

Do not touch switch with wet hands. This poses a risk of electric shock.

The module must be grounded. Do not connect the ground wire to gas /

water lines, lightning rods / telephone grounding lines. Improperly

grounded module poses a risk of electric shock.

Use circuit breakers (ground fault interrupter, isolating switch (+B fuse),

and moulded case circuit breaker) with the specified capacity. Failure of

Commissioning

21.10.2015 42 / 60


module / fire may result from circuit breaker when capacity exceeds

specifications

Do not touch refrigerant tubes with bare hands during operation. The re-

frigerant tubes are hot / cold, depending on condition of flowing refriger-

ant. Contact with tubes poses a risk of burns / frostbite.

Turn on main power switch 12 hours before starting operation.

This allows the oil sump heater to bring lubricant to operating temperature.

Starting operation directly after turning on power switch can cause severe

damage to internal parts. Keep main power switch on during period of ope-

ration.

After finishing operation, wait at least five minutes before turning main

power switch off. Otherwise, there is a risk of water leak / module failure.

Risk of total loss!

Repeated restart of the heat pump can result in total loss!

In case of heat pump failure, an inspection by qualified and authorised

personnel must be performed before restart.

Info: Controller settings must initially only be performed during the first

start of the machine.

During restart this is not necessary since the settings are stored (the set-

tings remain stored even in case of power failure).

Info: During initial commissioning, the specified values are often outside

the limits in the beginning, thus numerous warnings can appear.

For this reason, service personnel can suppress the warning messages

for this period; see Operating instructions for heat pump controller.

After completing installation and wiring and tubing of indoor and outdoor

modules, check for refrigerant leaks, loose power supply or control wir-

ing, wrong polarity, and ensure that no single phase in the power supply

is disconnected.

Check also the solidification point of the water-glycol mixture. It must be

below the expected minimum temperature of the medium.

Risk of total loss!

Do not start module if insulation resistance is below 1.0 MΩ.

Commissioning

21.10.2015 43 / 60


Insulation resistance

After installation or after module has been cut off from power supply for an

extended period, the insulation resistance will drop below 1 MΩ due to re-

frigerant accumulating in the compressor. This is not a malfunction. Pro-

ceed as follows:

1. Remove wires from compressor and measure insulation resistance

of compressor.

2. If insulation resistance is below 1 MΩ, the compressor is faulty or

the resistance dropped due to refrigerant accumulation in com-

pressor.

3. After wires are connected and power is switched on, compressor

starts to warm up. Remeasure insulation resistance based on acti-

vation times indicated below.

The insulation resistance drops due to refrigerant accumulation in

the compressor. Resistance will rise above 1 MΩ after compressor

has warmed up for 4 hours.

(The required compressor warm-up time varies according to at-

mospheric conditions and refrigerant accumulation.)

To operate the compressor with refrigerant accumulation, it must

be warmed up at least 12 hours to prevent failure.

4. If insulation resistance rises above 1 MΩ, the compressor is not

faulty.

10.2 Initial start of heat pump

The initial start of the heat pump is performed by a qualified

WATERKOTTE system partner.

Figure 11:ON / OFF switch (arrow)

Switch is lit => power supply switched on (regular operation)

Starting operation directly after turning on power switch can cause severe

damage to internal parts! Keep main power switch on during period of op-

eration.After all checks have been conducted (Kap. 10), proceed as follows:

1. Turn on main power switch (on heat pump)

2. The compressor does not start immediately, because the oil dump

Commissioning

21.10.2015 44 / 60


heater has to heat the oil up to operating temperature. This takes

up to 30 min in cool ambient temperature.

3. Once the operating temperature is reached, the compressor starts.

10.3 Control of entire operation

This heat pump is equipped with an efficient electronic control system. All

necessary settings and options are described in the controller manual.

Tip: The correct use of the controller saves money. Particularly the correct

settings of flow temperature, hot water temperature, heating curve and

heating times can result in substantial cost savings.

10.4 Turning heat pump off

After finishing operation, wait at least five minutes before turning main pow-

er switch off. Otherwise, there is a risk of water leak / module failure.

Procedure:

Switch off main switch of heat pump.

Switching off circuit breaker: Compressor, control voltage and electrical

heating element.

10.5 Taking heat pump out of operation for extended period

- see 10.4-

Total loss (freezing)

At low outdoor temperatures the device and the pipes must be protected

from freezing.

14 Maintenance and inspection

Have your WATERKOTTE heat pump maintained annually. This will ensure

the operational safety and efficiency of your heat pump. Additional infor-

mation is available from your WATERKOTTE service partner.

During maintenance, the technical condition of the heat pump system is

checked as well (target / actual comparison). In this process, a diagnostic

measurement of the thermodynamic part ensures that the efficiency is

maintained at an optimum level.

Note:

In the event of severe contamination it is recommended to clean the mod-

ule between maintenance cycles. At the same time, also remove residues

such as leaves and the like from the defrosting tray and check the conden-

sation drain (blockages) of the outdoor module.

Additional inspection points are:

Check heating circuit: System pressure, function of expansion tank, venting, rotation direction of pump and volume setting.

Check cooling circuit: Screw connections, tightness, charge level, refrig-erant control, diagnosis measurement log.

Check setting of control. Tightness check: The legally required test intervals are dependent on re-

frigerant charge weight. Refer to heat pump log book for more detailed information.
