mode for the use in systems provided with radiant panels and

traditional systems provided with terminal units.

CUTTING EDGE TECHNOLOGY: The constant drive for

improvement led Clivet introducing special constructive

features in ELFOEnergy Extended Inverter: the hydrophilic

coil ensures efficiency in any conditions, thermostatic

electronics optimises the cooling circuit operation with DC

Inverter compressor, the water kit simplifies the hydronic

circuit and facilitates maintenance. The unit can be equipped

with DC Inverter circulator (optional), which guarantees

further energy saving thanks to the modulation of the water

flow-rate depending on the load and pressure drops of the

system.

MAXIMUM SILENT OPERATION: ELFOEnergy Extended

Inverter is at the top of its class, due to an optimised profile of

the fan and modulation of both the fan and compressor,

according to the outdoor conditions and load of the system.

3.1 PRELIMINARY INFORMATION • install flexible joints on the hydraulic.

A correct circulation of the air is indispensible to guarantee the

good working order of the machine.

Avoid therefore:

• obstacles to the airflow;

• exchange difficulties;

• leaves or other foreign bodies that can obstruct the

exchange batteries;

• winds that hinder or favour the airflow;

• heat or pollution sources close to the unit (chimneys,

extractors etc);

• stratification (cold air that stagnates at the bottom);

• recirculation (expelled air that is sucked in again);

• positioning below the level of the threshold, close to very

high walls, attics or in angles that could give rise to

stratification or recirculation phenomenons.

Ignoring the previous indications could:

• energy efficiency decrease;

• blocks due to HIGH PRESSURE (in summer) or LOW

PRESSURE (in winter).

3.2 SPAZI FUNZIONALI

3.3 POSITIONING

Functional spaces are designed to:

• guarantee good unit operation

• carry out maintenance operations

• protect authorized operators and exposed people

3.4 CONDENSATE WATER

When a heat pump is running it produces a considerable

amount of water due to the defrosting cycles of the external

coil.

The condensation must be eliminated in a manner to avoid

wetting pedestrian areas.

The unit anti-freeze electric resistance prevents the ice from

forming inside the tray.

With extensive very cold outdoor temperatures, condensation

could freeze outside the unit blocking the flow and causing a

slow build-up of ice; therefore special attention must be paid

to eliminating condensation, raising the unit off the ground and

evaluating whether antifreeze elements should be installed.

CUT-OFF VALVES

• Installed at inlet and outlet (both on the water technique

circuit as well as that of the hot domestic water) allow

maintenance operations without having to empty the

system .

THERMOMETERS AND MANOMETERS

• Installed at entry and exit of the main elements facilitate

inspection and maintenance.

AIR BLEED VALVE

• Installed in all of the highest points of the system allowing

the venting of the circuits air..

DRAINAGE TAPS

• Installed in the lowest points of the system to allow

bleeding.

EXPANSION TANK

• It keeps a correct system pressure when the water

temperature changes. It must be dimensioned as a

function of water plant volume and temperature.

SUPPORTS

• The hydraulic pipes weight mustn’t burden on the unit

connections .

ANTIVIBRATION JOINTS

• They avoid the vibration transmission on water connections

INERTIAL STORAGE TANK

• is necessary in the event of the following :

- the water in the system is very low

- the unit will not be used in a private house (in an

industrial process or other)

4.3 OPERATION SEQUENCE

1. Execute leakage test

2. Carefully wash the system by filling it and emptying it

several times with clean water.

Ignoring this operation will lead to several filter cleaning

interventions and at worst cases can cause damages to

the exchangers and the other parts.

3. Prepare anti-freeze solution if required

4. Fill the plant

5. vent the plant

6. Isolate the pipes to avoid heat dispersions and formation

of condensate isolate all the pipes.

Leave various point of service free (wells, vent-holes etc ).

4.4 WATER QUALITY

The water quality is determined by the following factors, avoid

therefore:

• Inorganic salts

• pH

• Biological load (seaweeds etc)

• Suspended solids

• Dissolved oxygen Water with inadequate characteristics can cause:

• pressure drop increase

• energy efficiency decrease

• corrosive symptom increase

The unit is equipped with an antifreeze function that activates

the circulator with water temperature < of 5°C.

The function is active only if the unit is on.

For greater safety if the unit or the relative water connections

can be subject to temperatures close to 0°C adopt measures

for prevent risk of freeze.

For example:

• Mix water with ethylene glycol

• Safeguard the pipes with heating cables placed under the insulation

• Empty the system in cases of long non-use and check that:

• there are no closed taps present that could trap water even after emptying

• there are no low points in which water can stagnate even after emptying; carry out any blowing required .

4.5 RISK OF FREEZE

4.6 ANTI-FREEZE SOLUTION

Consider that the use of anti-freeze solution determines an

increase in a pressure drop.

Make sure that the glycol type utilized is inhibited (not

corrosive) and compatible with the hydraulic circuit

components (pump etc).

Do not use different glicol mixture (i.e. ethylene with

propylene)

Selection and installation of system components must be

carry out by installer.

Following you will find some indications to integrate with what

is provided by the local regulations in force and by the good

technical laws.

• at the first unit start-up

• after each prolonged period of inactivity

1. Supply the resistances switching off the unit isolator

switch.

2. To make sure that hte resistances are working, check the

power input .

3. At start-up the compressor crank-case temperature on the

lower side must be higher at least of 10°C than the outside

temperature.

Do not start the compressor with the crankcase oil below

operating temperature.

Start the unit

With unit of full load, namely in stable conditions and close to those of work, check :

• Power supply tension

• Total absorption of the unit

• Absorption of the single electric loads

6.6 TENSIONS

6.8 STARTING REPORT

Realize the operating objective conditions is useful for check

the unit over time.

With unit of full load, namely in stable conditions and close to

those of work, take the following data:

• Tension and general absorptions with unit at full load

• Absorption of varied electrical loads (compressors, fans, pumps etc)

• Temperatures and capacities of different liquid (water, air) in the inlet and outlet of the unit

• Temperatures and pressures on the refrigerant circuit characteristic points (compressor discharge, liquid, intake)

The remarks should be preserved and available during maintenance .

97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well.

Refer to local actuation norms; briefly and as an example, see the following

• Compulsory verification of the first installation :

only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)

• Certification of setting in service :

for all the units

• Periodical verifications:

to be executed with the frequency indicated by the manufacturer (see the maintenance section)

6.9 CE 97/23 PED DIRECTIVE

• Check that the remote commands (ON-OFF, etc.) are connected and if necessary enabled with the relevant parameters as described in ELECTRICAL CONNECTIONS section

• Check that probes or optional components are connect and enable with the relative parameters( ELECTRICAL CONNECTION section)

8 - MAINTENANCE

8.2 GENERAL

Maintenance must be done by authorized centres or by

qualified personnel

The maintenance enables:

• maintain the unit efficiency

• Reduce the deterioration speed to whom every equipment is subject over time

• Assemble information and data to understand the state of the unit efficiency and avoid possible damages

The inspections should be carried out at least every six months

The frequency, however, depends on the use . In the event of frequent use it is recommended to plan inspections at close intervals :

• frequent use (continuous or very intermittent use, near the operating limits, etc)

• critical use (service necessary) .

It is very important for the exchanger to be able to provide the

maximum thermal exchange. Therefore, it is essential for the

inner surfaces to be clean of dirt and incrustations.

Periodically check the difference between the temperature of

the supply water and the condensation temperature. If the

difference is greater than 8 °C – 10 ° C it is advisable to clean

the exchanger.

The clearing must be effected :

• With circulation opposite to the usual one

• With a speed at least 1,5 times higher than the nominal one

• With an appropriate product moderately acid (95% water + 5% phosphoric acid

• After the cleaning rince with water to inhibe the detergent rests.

8.8 ELECTRIC FANS

8.7 WATER EXCHANGER

Check :

• the fans and the relative protection gridsare well fixed

• The fan bearings (evident by noise and anomalous vibrations )

• the terminal protection covers are closed and the cable holders are properly positioned

8.4 MACHINE BOOKLET

It’s advisable to create a machine booklet to take notes of the

unit interventions.

In this way will be easier marker the various interventions and

will be e facilitate any troubleshooting.

Report on the booklet :

• data

• type of intervention effected

• intervention description

• Carried out measures etc ..

If a long period of inactivity is foreseen

• Turn of the power in order to avoid electrical risks or

damages by lightning strike

• avoid the risk of frosts (empty or add glycol in the plant

sections subjected to temperatures below zero , power

antifreeze resistances if are present )

It’s recommended that the starter after the period of detention is

made by a qualified technician, especially after seasonal stops

or seasonal switch.

When restarting, refer to the START-UP section .

Schedule technical assistance in advance to avoid hitches and

be able to use the installation when necessary.

8.5 PUT A REST

Verify that there are no impurities which hinder the smooth

passage of water.

8.9 CIRCULATION PUMPS

Verify :

• no leaks

• Bearing status (anomalies are highlighted by abnormal noise and vibration)

• The closing of the terminals cover and the correct positioning of the cable glands.

Contact with the exchanger fins can cause cuts. Wear

protective gloves to perform the above described operations.

It is extremely important that the battery gives the maximum

thermal exchange; therefore, its surface must be cleaned from

dust and deposits. Remove all impurities from the surface.

It is extremely important that the battery gives the maximum

thermal exchange; therefore, its surface must be cleaned from

dust and deposits. Remove all impurities from the surface.

Using an air pressure gun, clean the aluminum surface of the

battery. Be careful to direct the air in the opposite direction of

the fan air movement.

Hold the gun parallel to the fins to avoid damages. As an

alternative, an aspirator can be used to suck impurities from

the air input side.

Verify that the aluminum fins are not bent or damaged. In the

event of damages, contact the authorized assistance center

and get the battery “ironed out” in order to restore the initial

condition for an optimal air flow

10 - DECOMMISSIONING

THE UNIT MUST ALWAYS BE SENT TO AUTHORISED

CENTRES FOR DISMANTLING AND DISPOSAL.

When dismantling the unit, the fan, the motor and the coil, if

operating, may be recovered by the specialist centres for

reuse.

All the materials must be recovered or disposed of in

compliance with the corresponding national standards in

force.

For further information on the decommissioning of the unit,

contact the manufacturer.

9.1 DISCONNECTING

Only authorised personnel must disconnect the unit.

• Avoid leak or spills into the environment .

• Before disconnecting the unit, the following must be recovered, if present:

- refrigerant gas - Anti-freeze solutions in the hydraulic circuit

• Awaiting dismantling and disposal, the unit can also be

stored outdoors, as bad weather and rapid changes in

temperature will not cause damage to the environment, if

electric, cooling and hydraulic circuits of the unit are

integral and closed.

The units covered by the legislation in question are marked

with the symbol on the side.

With the aim of protecting the environment, all of our units are

produced in compliance with Directive EC on waste electrical

and electronic equipment (WEEE).

The potential effects on the environment and on human health

due to the presence of hazardous substances are shown in the

use and maintenance manual in the section on residual risks.

Information in addition to that indicated below, if required, can

be obtained from the manufacturer/distributor/importer, who

are responsible for the collection/handling of waste originating

from equipment covered by EC - WEEE. This information is

also available from the retailer who sold this appliance or from

the local authorities who handle waste.

Directive EC - WEEE requires disposal and recycling of

electrical and electronic equipment as described therein to be

handled through appropriate collection, in suitable centres,

separate from collection for the disposal of mixed urban waste.

The user must not dispose of the unit at the end of its life cycle

as urban waste. It must instead be handed over to appropriate

collection centres as set forth by current standards or as

instructed by the distributor.

If disposal takes places at the same time as delivery of a new

electrical or electronic equipment for the same family, the

product may be collected directly by the distributor.

11 - RESIDUAL RISKS

Smell of burning, smoke or other signals of serious anomalies may indicate a situation which could cause damage to people, things or the unit itself.

Electrically isolate the unit (yellow-red isolator).

Contact the authorised service centre to identify and resolve the problem at the source of the anomaly.

Accidental contact with exchange batteries, compressors, air

delivery tubes or other components may cause injuries and/or burns.

Always wear suitable clothing including protective gloves to work inside the danger zone.

Maintenance and repair operations carried out by non-qualified personnel may cause damge to persons, things or the unit itself.

Always contact the qualified assistance centre.

Failing to close the unit panels or failure to check the correct tightening of all of the panelling fixing screws may cause damage to persons, things or the unit itself.

Periodically check that all of the panels are correctly closed and fixed.

If there is a fire the temperature of the refrigerant could reach values that increase the pressure to beyond the safety valve with the consequent possible projection of the refrigerant itself or explosion of the circuit parts that remain isolated by the closure of the tap.

Do not remain in the vicinity of the safety valve and never

leave the refrigerating system taps closed.

11.4 INSTALLATION

11.5 GENERAL RISKS

11.6 ELECTRICS PARTS

In this section the most common situations are signalled. As these cannot be controlled by the manufacturer these could be a source of risk situations for people or things

This is an area in which only an authorised operator may work.

The danger zone is the area inside the unit which is accessible only with the deliberate removal of protections or parts thereof

The handling operations, if implemented without all of the protection necesssary and without due caution, may cause the fall or the tipping of the unit with the consequent damage, even serious, to persons, things or the unit itself.

Handle the unit following the instructions provided in the pre-sent manual regarding the packaging and in compliance with the local regulations in force.

Should the gas refrigerant leak please refer to the refrigerant "Safety sheet".

An incorrect installation of the unit could cause water leaks, condensate accumulation, leaking of the refrigerant, electric shock, bad functioning or damage to the unit itself.

Check that the installation has been implemented by qualified technical personnel only and that the instructions contained in the present manual and the local regulations in force have been adhered to.

The installation of the unit in a place where even infrequent leaks of inflammable gas and the accumulation of this gas in the area surrounding the area occur could cause explosions or fires.

Carefully check the positioning of the unit.

The installation of the unit in a place unsuited to support its weight and/or guarantee adequate anchorage may cause the fall or the tipping of the unit with the consequent damage to things, people or the unit itself.

Carefully check the positioning and the anchoring of the unit.

Easy access to the unit by children, unauthorised persons or animals may be the source of accidents, some serious.

Install the unit in areas which are only accessible to authori-sed person and/or provide protection against intrusion into the danger zone .

An incomplete attachment line to the electric network or with incorrectly sized cables and/or unsuitable protective devices can cause electric shocks, intoxication, damage to the unit or fires.

Carry out all of the work on the electric system referring to the electric layout and the present manual ensuring the use of a system thereto dedicated.

An incorrect fixing of the electric components cover may favour the entry of dust, water etc inside and may consequently can electric shocks, damage to the unit or fires.

Always fix the unit cover properly.

When the metallic mass of the unit is under voltage and is not correctly connected to the earthing system it may be as source of electric shock and electrocution.

Always pay particular attention to the implementation of the earthing system connections.

Contact with parts under voltage accessible inside the unit after the removal of the guards can cause electric shocks, burns and electrocution.

Open and padlock the general isolator prior to removing the guards and signal work in progress with the appropriate shield.

Contact with parts that could be under voltage due to the start up of the unit may cause electric shocks, burns and electrocution.

When voltage is necessary for the circuit open the isolator on the attachment line of the unit itself, padlock it and display the appropriate warning shield.
