3. INSTALLATION WORK

Please obtain the approval of the customer when selecting the location of installation
and installing the unit.

3. 1. Selecting an installation location

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.
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 fi 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 nor-
mally.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline. If gas
leaks and settles around the unit, it can cause a fi re.
• Area that has heat sources, vapors, or the risk of the leakage of fl ammable gas in
the vicinity.
• Area where small animals may live. It may cause failure, smoke or fi re if small
animals enter and touch internal electrical parts.
• Area where animals may urinate on the unit or ammonia may be generated.
Please install the outdoor unit without slant.
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 airfl 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
control cable at least 40 in. (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 40 in. (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.

3. 2. Installation dimensions

Select installation locations that can properly support the weight of the indoor and out-
door units. Install the units securely so that they do not topple or fall.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near heat source of heat, steam, or fl ammable gas.
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Install the unit where it will not be tilted by more than 3˚. However, do not install the
unit with it tilted towards the side containing the compressor.
When installing the outdoor unit where it may exposed to strong wind, fasten it secure-
ly.
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 airfl 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 airfl ow.)
(4) Do not install the unit near a source of heat, steam, or fl ammable gas.
(5) During heating operation, drain water fl ows from the outdoor unit.
Therefore, install the outdoor unit in a place where the drain water fl ow will not be
obstructed. (Reverse cycle model only)
(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.
