OUTDOOR UNIT LOCATION
Precautions
Avoid installing the outdoor unit in the following locations:
Where there is danger of flammable gas leakages.
Where there are high concentrations of oil.
Where the atmosphere contains an excess of salt (as in coastal areas). The air conditioner is prone to
failure when used under this condition unless special maintenance is provided.
Where the airflow from the outdoor unit may cause annoyance.
Where the operating noise of the outdoor unit may cause annoyance.
Where the foundation is not strong enough to fully withstand the weight of the outdoor unit.
Where the water drainage may cause a nuisance or a hazard when frozen.
Where strong winds may blow against the air outlet of the outdoor unit.
(The high pressure switch could be tripped if a strong wind should blow against the air outlet during
cooling operation). Where this condition is likely to be present, protect the outdoor unit against winds, for
example by:
Installing the outdoor unit in parallel with the building so that it can be protected by other buildings:
Building
Strong wind
Installing the outdoor unit with the air outlet facing the wall, such as on an exposed rooftop:

OUTDOOR UNIT LOCATION
Service Space
Ensure that there is sufficient space around the outdoor unit for operation, installation and servicing;
Any obstructions of the airflow must be at least 300 mm from the front of the unit;
All dimensions are minimum.

Mounting
Do not allow units to be situated so that outlet air from one unit is discharged directly into the intake of
another unit as indicated below:

Mounting (continued)
Secure the outdoor unit to a sturdy and flat foundation using four anchor bolts.
The anchor bolt pitch is shown in the diagram below:

In areas subject to heavy snowfalls, protect the outdoor unit from snow as follows:
(i) Install the unit on a stand which will keep the unit above the level of the standing snow.
(ii) The stand must facilitate water drainage.
(iii) Install snow protection hoods over the air intake and outlet. Ensure that the airflow is not affected.
Failure to take adequate measures in this respect may result in the unit malfunctioning.

INDOOR UNIT LOCATION
Location Precautions
Avoid installing the indoor unit in the following locations:
Where there is danger of flammable gas leakages.
Where there are high concentrations of oil.
Where the atmosphere contains an excess of salt (as in coastal areas). The air conditioner is prone to
failure when used under this condition unless special maintenance is provided.
Where high concentrations of organic solvent are present.
Where a machine that generates a high frequency is operated.
Where the unit will not be horizontal.
Where the ceiling height is more than 3 m.
Where the floor/wall/ceiling structure is unable to support the weight of the unit.
Where it is not possible to fix the unit hangers, e.g. window glass.
Locate the unit so as to provide uniform circulation of chilled air.
Avoid locating the unit as shown in the -marked figures below:
Good location
Evenly cooled
If a good location is not possible, use a fan to circulate the air evenly throughout the room.
Bad location
Shaded area not well cooled
Bad location
Shaded area not well cooled

When the installation plate is directly mounted on the wall
1. Securely fix the installation plate to the wall by screwing it through the upper and lower fixing holes.
2. To mount the installation plate on a concrete wall with anchor bolts, utilize the anchor bolt holes as
illustrated in the above figure.
3. Install the installation plate horizontally in the wall.
CAUTION:
When installing the installation plate with mounting screw, do not use the anchor bolt hole. Otherwise the
unit may fall down and result in personal injury and property damage.
