Never touch the internal parts of the remote controller.

Touching certain internal parts will cause electric shocks 
and damage to the remote controller. Consult your local 
dealer about checking and adjustment of internal parts.

To avoid oxygen deficiency, ensure that the room is 
adequately ventilated if equipment such as a burner is 
used together with the air conditioner.
Do not leave the remote controller wherever there is a 
risk of wetting.

If water gets into the remote controller there is a risk of 
electrical leakage and damage to electronic components.

Watch your steps at the time of air filter cleaning or 
inspection.

High-place work is required, to which utmost attention must 
be paid.
If the scaffold is unstable, you may fall or topple down, thus 
causing injury.

Do not remove the outdoor unit’s outlet side grille.

The grille protects against the unit’s high speed fan, which 
may cause injury.

To avoid injury, do not touch the air inlet or aluminum 
fins of the air conditioner.
Do not place objects that are susceptible to moisture 
directly beneath the indoor or outdoor units.

Under certain conditions, condensation on the unit or 
refrigerant piping, air filter dirt or drain blockage may cause 
dripping, resulting in fouling or failure of the object 
concerned.

Do not place heaters directly below the indoor unit, as 
resulting heat can cause deformation.
Do not place appliances that produce naked flames in 
places exposed to the airflow from the air conditioner 
as this may impair combustion of the burner.
Do not block air inlets nor outlets.

Impaired airflow may result in insufficient performance or 
trouble.

Do not use the air conditioner for purposes other than 
those for which it is intended.

Do not use the air conditioner for cooling precision 
instruments, food, plants, animals or works of art as this 
may adversely affect the performance, quality and/or 
longevity of the object concerned.

Do not install the air conditioner at any place where 
there is a danger of flammable gas leakage.

In the event of a gas leakage, build-up of gas near the air 
conditioner may result in a fire.

Carry out drain piping properly to ensure complete 
drainage.

If drain piping is not carried out properly, drain will not flow 
out. Then, dirt and debris may be accumulated in the drain 
piping and may cause water leakage. If it occurs, stop the 
air conditioner and call your local dealer for assistance.

• NOTE TO SERVICE PERSONNEL

WARNING

RISK OF ELECTRIC SHOCKS OR A FIRE

When checking the electric components (such 
as the inside of the control box, fan motor, drain 
pump, etc.), make sure to shut off all power 
supply for the air conditioner (including both 
indoor and outdoor units).

When cleaning the heat exchanger, make sure 
to remove the electronic components above (If 
they get cleaning agent, there is a risk that the 
components will burn out because of insulation 
degradation). 

CAUTION! DANGER OF ELECTRIC 

Shut off power supply before work.

Never open the control box lid for 10 minutes 
after shutting off the power supply because 
there is residual voltage.

After opening the control box lid, measure 
residual voltage between the points shown in 

Fig. 1

 on the printed circuit board by the tester 

without touching the live part and confirm that 
the residual voltage is DC50V or below.

After power failure, operation will restart 
automatically.

2. WHAT TO DO BEFORE 

OPERATION

This operation manual is for the following systems 
with standard control.
Before initiating operation, contact your local dealer 
for the operation that corresponds to your system.
