4. INSTALLATION WORK

Make sure to obtain the customer’s approval for selecting and installing the outdoor unit.

4.1. Selecting an installation location

WARNING

Securely install the outdoor unit at a location that can withstand the weight of the unit.
Otherwise, the outdoor unit may fall and cause injury.

Be sure to install the outdoor unit as prescribed, so that it can withstand earthquakes
and typhoons or other strong winds. Improper installation can cause the unit to topple
or fall, or other accidents.

Do not install the outdoor unit near the edge of a balcony. Otherwise, children may
climb onto the outdoor unit and fall off of the balcony.

CAUTION

Do not install the outdoor unit in the following areas:

• Area with high salt content, such as at the seaside. It will deteriorate metal parts,

causing the parts to fail or the unit to leak water.

• Area

lled with mineral oil or containing a large amount of splashed oil or steam,

such as a kitchen. It will deteriorate plastic parts, causing the parts to fail or the unit
to leak water.

• Area that generates substances that adversely affect the equipment, such as

sulfuric gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed
joints to corrode, which can cause refrigerant leakage.

• Area containing equipment that generates electromagnetic interference. It will

cause the control system to malfunction, preventing the unit from operating
normally.

• Area that can cause combustible gas to leak, contains suspended carbon

bers or

ammable dust, or volatile in

ammables such as paint thinner or gasoline. If gas

leaks and settles around the unit, it can cause a

re.

• Area that has heat sources, vapors, or the risk of the leakage of

ammable gas in

the vicinity.

• Area where small animals may live. It may cause failure, smoke or

re if small

animals enter and touch internal electrical parts.

• Area where animals may urinate on the unit or ammonia may be generated.

Do not tilt the outdoor unit more than 3 degrees. However, do not install the unit with it
tilted towards the side containing the compressor.

Install the outdoor unit in a well-ventilated location away from rain or direct sunlight.

If the outdoor unit must be installed in an area within easy reach of the general public,
install as necessary a protective fence or the like to prevent their access.

Install the outdoor unit in a location that would not inconvenience your neighbors, as
they could be affected by the air

ow coming out from the outlet, noise, or vibration. If it

must be installed in proximity to your neighbors, be sure to obtain their approval.

If the outdoor unit is installed in a cold region that is affected by snow accumulation,
snow fall, or freezing, take appropriate measures to protect it from those elements. To
ensure a stable operation, install inlet and outlet ducts.

Install the outdoor unit in a location that is away from exhaust or the vent ports that
discharge vapor, soot, dust, or debris.

Install the indoor unit, outdoor unit, power supply cable, connection cable, and remote
controller cable at least 1 m away from a television or radio receivers. The purpose of
this is to prevent TV reception interference or radio noise. (Even if they are installed
more than 1 m apart, you could still receive noise under some signal conditions.)

If children under 10 years old may approach the unit, take preventive measures so that
they cannot reach the unit.

Keep the length of the piping of the indoor and outdoor units within the allowable range.

For maintenance purposes, do not bury the piping.

Decide the mounting position with the customer as follows:
(1) Install the outdoor unit in a location which can withstand the weight of the unit and

vibration, and which can install horizontally.

(2) Provide the indicated space to ensure good air

ow.

(3) If possible, do not install the unit where it will be exposed to direct sunlight.

(If necessary, install a blind that does not interfere with the air

ow.)

(4) Do not install the unit near a source of heat, steam, or

ammable gas.

(5) During heating operation, drain water

ows from the outdoor unit.

Therefore,

install

the

outdoor

unit in a place where the drain water

ow will not be

obstructed.

(6) Do not install the unit where strong wind blows or where it is very dusty.
(7) Do not install the unit where people pass.
(8) Install the outdoor unit in a place where it will be free from being dirty or getting wet by

rain as much as possible.

(9) Install the unit where connection to the indoor unit is easy.

4.2. Drain installation

CAUTION

Perform drain work in accordance with this Manual, and ensure that the drain water is
properly drained. If the drain work is not carried out correctly, water may drip down from
the unit, wetting the furniture.

When the outdoor temperature is 0 °C or less, do not use the accessory drain pipe
and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may
freeze in extremely cold weather.

Since the drain water

ows out of the outdoor unit during heating operation, install the drain

pipe and connect it to a commercial 16 mm hose.
When installing the drain pipe, plug all the holes other than the drain pipe mounting hole in
the bottom of the outdoor unit with putty so there is no water leakage.
