CAUTION
• This appliance is intended to be used by expert or trained users in shops, in light industry and on farms, or
for commercial and household use by lay persons.
• Sound pressure level is less than 70 dB(A).
• Carry out drain piping properly following this installation manual and insulate the pipe to prevent condensation.
Improper drain piping may result in indoor water leakage and property damage.
• Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions
or radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)
• Install the indoor unit as far as possible from fluorescent lamps.
If a wireless kit is installed in a room where the electronic lighting type (inverter or rapid start types)
fluorescent lamps exist, the transmitting distance of a remote controller may be shorter.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).
Plastic parts may deteriorate and cause parts to fall off or water to leak.
2. Where corrosive gas, such as sulphurous acid gas, is produced.
Corrosion of copper pipes or brazed parts may occur and cause refrigerant leakage.
3. Where there is a machine that generates electromagnetic wave and where voltage fluctuation often
occurs such as a factory.
Control system may malfunction and as a result the unit may not properly operate.
4. Where flammable gas may leak, where carbon fibre or ignitable dust is suspending in the air, or where
volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
• The air conditioner is not intended for use in a potentially explosive atmosphere.
• Do not install in sealed, highly airtight spaces such as soundproof chambers and room which was sealed
up the door (only for R32 refrigerant).
• Do not install in places filled with smoke, gas, chemicals etc.
There is a possibility that the sensors inside the indoor unit could detect these, and display a refrigerant
leak abnormality (only for R32 refrigerant).
• This unit is equipped with a refrigerant leak detector for safety. To be effective, the unit must be electrically
powered at all times after installation, other than short service intervals (only for R32 refrigerant).
2. BEFORE INSTALLATION
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
Be sure to check in advance that the refrigerant to be used for installation is R32 or R410A. (If a wrong
refrigerant is charged, the unit will not properly operate)
• For the installation of an outdoor unit, refer to the installation manual attached to the outdoor unit.
• Do not dispose of any parts necessary for installation until the installation is completed.
• Decide the route for carrying the unit to the installation site.
• When hanging the unit for lifting, use a sling of soft material (made of cloth, nylon, etc.) as shown below.
(Refer to Fig. 1)
(1) Horizontal hanging
(2) Vertical hanging
Sling
*Be sure that the sling
does not slide.
Sling
Apply cloth or corrugated
cardboard so that the air
discharge grille and air inlet
grille will not be damaged.
