1-3. SPECIFICATIONS

1-3-1. POWER SUPPLY AND INDOOR/OUTDOOR WIRE CONNECTION

• Power should be taken from an exclusive branched circuit.

• 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 AWG14 or stranded conductor AWG14.

• Use double insulated copper wire with 600 V insulation.

• Use copper conductors only.

* Follow local electrical codes.

Power supply cable and ground wire

• Use solid or stranded conductor AWG12.

• 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.

Pipe length

Up to 25 ft. (7.5 m)

No additional charge is re-

quired.

Exceeding 25 ft. (7.5 m)

Additional charge is required.

(Refer to the table below.)

• Refrigerant adjustment... If pipe length exceeds 25 ft. (7.5 m), additional refrigerant

(R410A) charge is required.

(The outdoor unit is charged with refrigerant for pipe length up to 25 ft. [7.5 m])

Limits

Pipe length 100 ft. (30 m) max.

Height difference 50 ft. (15 m) max.

No. of bends 10 max.

• 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.

1-3-2. REFRIGERANT PIPES

• To prevent condensation, insulate the two refrigerant pipes.

• Refrigerant pipe bending radius must be 4 in. (100 mm) or more.

INDOOR UNIT

 :KHUHDLUÀRZLVQRWEORFNHG

• Where cool air aspreads over the entire room.

• On a rigid wall to reduce the possibility of vibration.

• Where it is not exposed to direct sunlight.

• Where it can be easily drained.

• At a distance 3 ft. (1 m) or more away from a TV and

radio. Operation of the air conditioner may interfere

with radio or TV reception. An amplifier may be re-

quired for the affected device.

• In a place as far away as possible from fluorescent

and incandescent lights (so the infrared remote control

can operate the air conditioner normally).

•

:KHUHWKHDLU¿OWHUFDQEHUHPRYHGDQGUHSODFHGHDVLO\

Note:

Install the indoor unit high on the wall where air can dis-

tribute over the entire room.

REMOTE CONTROLLER

• Where it is convenient to operate and easily visible.

• Where children cannot easily touch it.

 6HOHFWDSRVLWLRQDERXWIWPDERYHWKHÀRRU

Check that signals from the remote controller from

that position are received by the indoor unit (‘beep’

or ‘beep beep’ receiving tone sounds). Then, attach

remote controller holder to a pillar or wall and install

wireless remote controller.

Note:

the signal from the wireless remote controller may not be

received.

OUTDOOR UNIT

• Where it is not overly exposed to strong winds.

 :KHUHDLUÀRZLVJRRGDQGGXVWOHVV

• Where neighbours are not annoyed by operation

sound or hot air.

• Where rigid wall or support is available to prevent the

increase of operation sound or vibration.

• Where there is no risk of combustible gas leakage.

• If installing the unit in a location high above the ground,

be sure to secure the unit legs.

• Where it is at least 10 ft. (3 m) away from the antenna

of TV set or radio. Operation of the air conditioner may

interfere with radio or TV reception in areas where re-

location where continuous direct sunlight or excessive

water can be avoided as much as possible.

Note:

When operating the air conditioner in low outside tem-

perature, be sure to follow the instructions described

below.

• Never install the outdoor unit in a place where its air

inlet/outlet side may be exposed directly to wind.

• To prevent exposure to wind, install the outdoor

unit with its air inlet side facing the wall and

board on the air outlet side.

Avoid the following places for installation where air

conditioner trouble is liable to occur.
