Choosing an Installation Site

Before choosing the installation site, obtain user approval.

1.

Indoor unit

The indoor unit should be sited in a place where: 

1) the restrictions on installation specified in the indoor unit installation drawings are met,
2) both air inlet and air outlet have clear paths met,
3) the unit is not in the path of direct sunlight,
4) the unit is away from the source of heat or steam,
5) there is no source of machine oil vapour (this may shorten indoor unit life),
6) cool (warm) air is circulated throughout the room,
7) the unit is away from electronic ignition type fluorescent lamps (inverter or rapid start type) as they may shorten the 

remote controller range,

8) the unit is at least 1m away from any television or radio set (unit may cause interference with the picture or sound),
9) install at the recommended height (1.8m),

10) no laundry equipment is located,

11) the appliance shall be stored so as to prevent mechanical damage from occurring.

2.

Wireless remote controller

Turn on all the fluorescent lamps in the room, if any, and find the site where remote controller signals are properly received by 
the indoor unit (within 6m).

CAUTION

• 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 cause a fire to break out. 

• Only qualified personnel can handle, fill, purge and dispose of the refrigerant.
• While following the instructions in this installation manual, install drain piping to ensure proper drainage and 

insulate piping to prevent condensation. 

Improper drain piping may result in indoor water leakage and property damage. 

• Tighten the flare nut according to the specified method such as with a torque wrench. 

If the flare nut is too tight, it may crack after prolonged use, causing refrigerant leakage. 

• 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).
