3. INSTALLATION WORK

Make sure to obtain the customer's approval for selecting and installing the outdoor 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.
• Calculate the proper refrigerant concentration if you will be installing it in an enclosed
location.
Total amount of replenished refrig-
erant in refrigerant facility [lb (kg)]
Capacity of smallest room where
unit is installed [1,000 ft³ (m³)]
If the results of the calculation exceed the concentration limit, increase the room
surface area or install a ventilation duct.
• 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
normally.
- 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.
• 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 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 unit in an area that would not cause problems even if the drain water is
discharged from the unit. Otherwise, provide drainage that would not affect people or
objects.
• 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 and connection 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.

CAUTION
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.
(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.

3.2. Installation dimensions

CAUTION
• Keep the space shown in the installation examples.
If the installation is not performed accordingly, it could cause a short circuit and result
in a lack of operating performance.
• When there is a wall in front of the unit, provide a space of 20 in (500 mm) or more
as maintenance space.
When there is a wall at the right side of the unit, provide a space of 2 in (25 mm) or
more as maintenance space.
• An outdoor temperature of 95 °F (DB) (35 °C (DB)) in air-conditioned operation is
assumed for the installation space in this item. If the outdoor temperature exceeds
95 °F (DB) (35 °C (DB)) and the outdoor unit is operating at a load exceeding its
rated ability, provide a larger inlet space.
• If you are installing more outdoor units than indicated here, ensure suffi cient space
or consult your distributing agent as it may affect the performance due to short circuit
and other problems.
• Consider the transportation route, installation space, maintenance space, and
access, and install the unit in a location with suffi cient space for the refrigerant
piping.
• Observe the installation space
specifi cations that are shown in the fi gures.
Keep the same space at rear air intake.
Provide the same space for the air intake
at the rear of the outdoor unit.
If the installation is not performed according
to the specifi cations, it could cause a short
circuit and result in a lack of operating
performance. As a result, the outdoor unit
might easily be stopped by high-pressure
protection.
• Installation methods not shown in the following examples are not recommended.
Performance may drop signifi cantly.
