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 3.5 feet (1m) away from any television or radio set (unit may cause interference with the picture or sound),
9) no laundry equipment is located.

WARNING

• During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, 
causing abnormally high pressure which could lead to equipment damage or and personal injury.

• During installation, attach the refrigerant piping securely before running the compressor.

If the refrigerant pipes are not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, 
causing abnormally high pressure which could lead to equipment damage and personal injury.

• Be sure to install a ground fault circuit interrupter breaker.

Failure to install a ground fault circuit interrupter breaker may result in electrically shocks, or fire personal injury.

CAUTION

• Do not install the air conditioner where gas leakage would be exposed to open flames.

If the gas leaks and builds up around the unit, it may catch fire.

• Establish drain piping according to the instructions of this manual. 

Inadequate piping may cause water damage.

• Tighten the flare nut according to the specified torque. A torque wrench should be used.

If the flare nut is tightened too much, the flare nut may crack over time and cause refrigerant leakage.

• Do not touch the heat exchanger fins.

Improper handling may result in injury.

• Be very careful about product transportation.

Some products use PP bands for packaging. Do not use any PP bands for a means of transportation. It is dangerous.

• Electrical work must be performed in accordance with the NEC/CEC by authorized personnel only.
