UNIQUE TECHNOLOGIES

BROAD Air Conditioning indoor units are Central Air Conditioning Terminal products. Their unique air quality

technologies have rewritten the century-old air conditioning history. They have met needs of modern architecture

with their exquisite & various models, easy installation & maintenance.

Electrostatic dust cleaning:Tungsten

laments of electrostatic cleaners

continuously release high voltage static

electricity. All particles in the air are

positively charged, then adsorbed by

negative plates. Particles tinier than

human cells and pollens are ltered,

which can protect the respiratory system,

and reduce drastically the cancer risks.

Electrostatic Bacteria Killing: Tungsten

laments of electrostatic cleaners

continuously release high voltage static

electricity at 6,000v. It kills instantlybacteria, viruses, and can stop all kinds

of airborne diseases.

Active Carbon Filter eliminates

formaldehyde: traps all kinds of toxic

gases like benzene, nicotine, etc.

Open shell by a slight touch

Use detergent and water to wash

To maintain constant purication efciency, once the cleaner is very dusty, it has to be taken out and cleaned

(once per month). Easy to wash with detergent or ultrasonic cleaner. Each time it only takes a few minutes.

OPTIONS

MODEL SELECTION GUIDANCE

Load selection cannot be roughly estimated, it is

closely related to building thermal insulation level

rather than building areas.

If a fast model selection is needed, please refer to P 2

“Areas(recommended m2)”.

One unit per room is recommended.

More units might be recommended for spacious room

with more furniture.

Inverter-controlled fan cuts energy consumption

drastically at low load operation.

Actually, air conditioners are running at low load

during 90% operation time.

Optional pre-set energy saving mode saves energy by

20%~30%.

Air cannot be blown directly to people.

Inverter-controlled fan makes the quiet operation.

Remote control: adjust temperature and air flow,

USD13/pc. One pc is recommended for one room,

for a room equipped with multiple fan coils, one is

recommended for 3 pcs. In public rooms like hotels

can use control panel instead.

Color: products have “standard color” please read

“Rated Parameters”, if customers prefer different colors,

additional 7% will be billed. It is also optional to choose

special panels, for instance, stainless steel, titanium, gold-

plating, price is high, lead time is longer.

1. Installation procedures

INSTALLATION TIPS

Pre-installed piping and wiringDuring the construction, A/C water supply & return tubes (with

pre-installed valve), condensate tubes, power supply cable,

signal wire shall be implemented to the location of indoor

units.Water pumps must be started circulation for 5 days at

least so that impurities inside tubes can be collected.

Shell installationIndoor units are to be installed after the room decoration.

Handle them with care to avoid any damage. Locate and

drill holes on the wall against the screw holes on the shell

back rst, then insert expansion bolts and mount the unit.

(Large model must be equipped with anchor bolts whereas

super large model may not apply them) .

Tube connectionConnect the pre-installed water supply tube, water return

tube and condensate tube to the i ndoor units. Check

&clean impurities of the water lter.Water return & supply

tubes can be connected with exible stainless steel bellows

Power connectionLead power cable from the wiring terminal to indoor power

supply. The power cable must comply with the local codes

and standards.

Controller installation(most models have installedcontrollers before shipment).The controller can be installed on a supporter supplied with

the unit, or lead 3×0.15mm2 control cable from the wiring

terminal and install the controller onto the wall nearby. The

location should be convenient to operate.

Notes:

All electric materials and methods for installation must comply

with the local codes and standards.

Specific connection refers to “Exterior wiring diagram”

attached with unit.

All the units must be of reliable grounding.

Stainless steel bellows (BROAD supply)

Outdoor thermometer installationLead a 2×0.3mm2 cable from indoor unit wiring termi nal.

Install the sensor outside the window and avoid direct

sunshine. The length of the cable should be less than 30m.

(If thermometer is separately purchased from BROAD,it must

be mounted in the sunshade box from BROAD).

3. Tips for shell installation

8. Air purication commissioningCompare particles from the outlet and inlet with particle

detector (or Particles instrument).

Take out the electrostatic cleaner after operating for a day

and check dust collection.

If not, there might be some faults. Please notify BROAD or

BROAD authorized service provider.

6. Power on inspection

7. A/C hydraulic balance commissioningStart up all indoor units in the whole building for cooling or

heating operation.

Check that whether the output of each indoor unit is

consistent. Use an infrared thermometer to test whether the air

outlet temp from each indoor unit is the same.

Turn up its ow regulating valve or turn down valves of nearby

indoor units if the air temp from an indoor unit cannot reach

the target. Repeat the adjustment till a hydraulic balance is

reached.

Generally the valve openness of those indoor units closer to

the chiller should be smaller.

After completion of whole building installation, keep the

chilled water pump running continuously for min. 5 days to

accumulate impurities at each lter. Wash the l ters before

indoor units are installed.

2. Tips for piping and wiring pre-installation

Pre-installed valve (BROAD supply)

W. return valve

Elbow for

temporary

circulation

W. supply valve

Water lter

Note: Please follow the marks to install and make sure not

to mix up the supply & return W. tubes, otherwise

coils will be clogged!

Fix the reserved location of pipeline wire and installation

height, then Install pipeline.

Copper tubes must be adopted in supply/ return water

tubes. Low temperature brazed welding is recommended

in connecting the tubes (450℃ hot air guns welding). The

A/C W. tubes should be covered with 30mm-80mm rubber

plastic cold insulation material and non-metal tubes can

be used for condensate tubes.

BROAD pre-installed valve should be installed at the end of

pipeline(as shown below). Water supply valve is also a ow

regulating valve which can balance the ow rate of each

indoor unit. It also has a shutoff function which facilitates

lter washing. The valve must be reset each time.

●

●

●

●

Keep the shell horizontal with no more than 2 mm gradient.

The expansion bolts should be strong enough to support at

least 3 times the weight of the shell (as there might be an

impact when the cover is opened).

Shut off the pre-installed valves (water return/ supply

valves), take out and wash water lter, then x them back.

Take out the bellows for temporary circulation and send it

back to BROAD.

Connect the pre-installed valves with indoor units by 2

stainless steel bellows of proper length.

The condensate tube must be with a certain gradient.

After the installation is completed, check the settings in

indoor unit controller item by item according to “Parameter

Setting” from User's Manual.

Pay special attention to the fan motor noise, outdoor/

indoor temperature and CO2 concentration.

Check indoor unit and lighting on/off through controller or

remote control.
