INSTALLATION

 

SITE

(See 

figure 1

 and 

figure 2

)

1

Select an installation site where the following conditions are
fulfilled and that meets your customer's approval.

-

Where optimum air distribution can be ensured.

-

Where nothing blocks air passage.

-

Where condensate water can be properly drained.

-

Where the false ceiling is not noticeably on an incline.

-

Where sufficient clearance for maintenance and service can 
be ensured.

-

Where there is no risk of flammable gas leaking.

-

The equipment is not intended for use in a potentially 
explosive atmosphere.

-

Where piping between indoor and outdoor units is possible 
within the allowable limit. (Refer to the installation manual of 
the outdoor unit.)

-

Keep indoor unit, outdoor unit, power supply wiring and 
transmission wiring at least 1 meter away from televisions 
and radios. This is to prevent image interference and noise in 
those electrical appliances. (Noise may be generated 
depending on the conditions under which the electric wave is 
generated, even if 1 meter is kept.)

-

When installing the wireless remote controller kit, the 
distance between wireless remote controller and indoor unit 
might be shorter if there are fluorescent lights who are 
electrically started in the room. The indoor unit must be 
installed as far as possible away from fluorescent lights.

-

Do not place objects that are susceptible to moisture directly 
beneath the indoor or outdoor units. Under certain 
conditions, condensation on the main unit or refrigerant 
pipes, air filter dirt or drain blockage may cause dripping, 
resulting in fouling or failure of the object concerned.

2

Ensure that a protective guard is installed on air suction and air
outlet side to prevent that the fan blades or heat exchanger be
touched.

The protection must comply with relevant European and national
regulations.

3

Use suspension bolts for installation. Check whether the ceiling
is strong enough to support the weight of the indoor unit. If there
is a risk, reinforce the ceiling before installing the unit.

Tick 

 

when 

checked

Is the indoor unit fixed firmly?

The unit may drop, vibrate or make noise.

Is the gas leak test finished?

It may result in insufficient cooling or heating.

Is the unit fully insulated and checked for air leaks?

Condensate water may drip.

Does drainage flow smoothly?

Condensate water may drip.

Does the power supply voltage correspond to that shown on the 
name plate?

The unit may malfunction or components may burn out.

Are wiring and piping correct?

The unit may malfunction or components may burn out.

Is the unit safely grounded?

Dangerous at electric leakage.

Is the wiring size according to specifications?

The unit may malfunction or components may burn out.

Is nothing blocking the air outlet or inlet of either the indoor or 
outdoor units?

It may result in insufficient cooling or heating.

Are refrigerant piping length and additional refrigerant charge 
noted down?

The refrigerant charge in the system might not be clear.

Are the air filters fixed properly (when installing with rear duct)?

Maintenance of the air filters can be impossible.

Is the external static pressure set?

It may result in insufficient cooling or heating.
