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, depending
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 remote 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 wire-
less 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 oc-
curring.
