Precautions for safety

The manufacturer shall not assume any liability for the damage caused 
by not observing the description of this manual.

General

• Before starting to install the air conditioner, read through the 

Installation Manual carefully, and follow its instructions to install the 

air conditioner.

• Only a qualified installer or service person is allowed to do installation 

work. Inappropriate installation may result in water leakage, electric 

shock or fire.

• Do not use any refrigerant different from the one specified for 

complement or replacement. Otherwise, abnormally high pressure 

may be generated in the refrigeration cycle, which may result in a 

failure or explosion of the product or an injury to your body.

• Before opening the intake grille of the indoor unit or service panel of 

the outdoor unit, set the circuit breaker to the OFF position. Failure to 

set the circuit breaker to the OFF position may result in electric 

shocks through contact with the interior parts. Only a Qualified 

installer (*1) or Qualified service person (*1) is allowed to remove the 

intake grille of the indoor unit or service panel of the outdoor unit and 

do the work required.

• Before carrying out the installation, maintenance, repair or removal 

work, set the circuit breaker to the OFF position. Otherwise, electric 

shocks may result.

• Place a “Work in progress” sign near the circuit breaker while the 

installation, maintenance, repair or removal work is being carried out. 

There is a danger of electric shocks if the circuit breaker is set to ON 

by mistake.

• Only a Qualified installer (*1) or Qualified service person (*1) is 

allowed to undertake work at heights using a stand of 50 cm or more 

or to remove the intake grille of the indoor unit to undertake work.

• Wear protective gloves and safety work clothing during installation, 

servicing and removal.

• Do not touch the aluminum fin of the unit. You may injure yourself if 

you do so. If the fin must be touched for some reason, first put on 

protective gloves and safety work clothing, and then proceed.

WARNING

• When work is performed at heights, use a ladder which complies with 

the ISO 14122 standard, and follow the procedure in the ladder’s 

instructions. Also wear a helmet for use in industry as protective gear 

to undertake the work.

• This unit is equipped with a refrigerant leak detection sensor for 

safety, to be effective, the unit must be electrically powered at all 

times after installation, other than when servicing. Turning off the 

circuit breaker cause refrigerant leak detection sensor not to operate 

and not to enable to detect refrigerant leaks, causing a fire.

• The refrigerant used by this air conditioner is the R32.

• The air conditioner must be transported in stable condition. If any part 

of the product is broken, contact the dealer.

• When the air conditioner must be transported by hand, carry it by four 

or more people.

• Servicing shall be performed only as recommended by the 

manufacturer. Do not move or repair any unit by yourself. There is 

high voltage inside the unit. You may get electric shock when 

removing the cover and main unit.

• This appliance is intended to be used by expert or trained users in 

shops, in light industry, or for commercial use by lay persons.

About the refrigerant R32

• The appliance shall be stored in a room without continuously 

operating ignition sources (for example: open flames, an operating 

gas appliance or an operating electric heater).

• Do not pierce or burn refrigerant cycle parts.

• Do not use means to accelerate the defrosting process or to clean, 

other than those recommended by the manufacturer.

• Be aware that refrigerants may not contain an odor.

• Pipe-work shall be protected from physical damage.

• Compliance with national gas regulations shall be observed.

•  If refrigerant leak detection sensor detects R32 refrigerant leak, a fan 

on indoor unit automatically operates to stir an air in the room. Stirring 

air flow volume of each model is as shown below.
