1-2. sELECtING tHE INstALLAtIoN LoCAtIoN

INDooR uNIt
• Where airflow is not blocked.
• Where cool (or warm) air spreads over the entire room.
• Where it is not exposed to direct sunshine. Do not expose to direct sunshine
also during the period following unpacking to before use.
• Where easily drained.
• At a distance 3 ft. (1 m) or more away from your TV and radio. Operation
of the air conditioner may interfere with radio or TV reception. An amplifier
may be required for the affected device.
• In a place as far away as possible from fluorescent and incandescent lights. In
order to make the infrared remote control operate the air conditioner normally.
The heat from the lights may cause deformation or the ultraviolet may cause
deterioration.
• Where the air filter can be removed and replaced easily.
• Where it is away from the other heat or steam source.

1-3. sPECIFICAtIoNs

1-3-1. INDooR/outDooR WIRE CoNNECtIoN

• Wiring work should be based on applicable technical standards.
• Wiring connections should be made following the diagram.
• Securely tighten screws.
Connecting wires and the ground wire
• Use solid conductor Min. AWG14 or stranded conductor
Min. AWG14.
• Use double insulated copper wire with 600 V insulation.
• Use copper conductors only.
* Follow local electrical codes.
Note:
When the indoor unit is powered from the outdoor unit, depend-
ing on local code, a disconnect switch needs to be installed to a
power supply circuit.
1-3-2. REFRIGERANt PIPEs
• To prevent condensation, insulate the two refrigerant pipes.
CAutIoN
Be sure to use the insulation of specified thickness (table on the
right). Excessive insulation may cause incorrect installation of
the indoor unit, and too little insulation may cause condensate
to form.
• The unit has flared connections on both indoor and outdoor
sides.
• Remove the valve cover from the outdoor unit, then connect
the pipe.
• Refrigerant pipes are used to connect the indoor and outdoor
units.
• Be careful not to crush or over bend the pipe in pipe bending.
REMotE CoNtRoLLER
• Where it is easy to operate and easily visible.
• Where children cannot touch it.
• Select a position about 4 ft. (1.2 m) above the floor and check that signals
from the remote controller are surely received by the indoor unit from that
position ('beep' or 'beep beep' receiving tone sounds). After that, attach re-
mote controller holder to a pillar or wall and install wireless remote controller.
Note:
In rooms where inverter type fluorescent lamps are used, the signal from the
wireless remote controller may not be received.
Note:
Avoid the following places for installation where air conditioner trouble is
liable to occur.
• Where flammable gas could leak.
• Where there is much machine oil.
• Where oil is splashed or where the area is filled with oily smoke (such as
cooking areas and factories, in which the properties of plastic could be
changed and damaged).
• Salty places such as the seaside.
• Where sulfide gas is generated such as hot spring, sewage, waste water.
• Where there is high-frequency or wireless equipment.
• Where there is emission of high levels of VOCs, including phthalate
compounds, formaldehyde, etc., which may cause chemical cracking.
• The appliance shall be stored so as to prevent mechanical damage from
occurring.
