Step 1: Select installation location.
The outdoor unit should be installed in the
location that meets the following requirements:
Place the outdoor unit as close to the indoor
unit as possible.
Ensure that there is enough room for
installation and maintenance.
The air inlet and outlet must not be
obstructed or exposed to strong wind.
Ensure the location of the unit will not be
subject to snowdrifts, accumulation of
leaves or other seasonal debris. If possible,
provide an awning for the unit that does not
obstruct airow or maintenance access.
The installation area must be dry and well
ventilated.
There must be enough room to install the
connecting pipes and cables and to access
them for maintenance.
Step 2: Install outdoor unit.
Fix the outdoor unit with anchor bolts (M10)
The area must be free of combustible gases
and chemicals.
The pipe length between the outdoor and
indoor unit may not exceed the maximum
allowable pipe length.
If possible, avoid installing the unit where
it is exposed to direct sunlight.
If possible, make sure the unit is located far
away from your neighbors’ property so that
the noise from the unit will not disturb them.
If the location is exposed to strong winds
(for example: near a seaside), the unit must
be placed against the wall to shelter it from
the wind. If necessary, use an awning with at
least 18” of clearance.
(See Fig. 6.1 & 6.2)
Install the indoor and outdoor units, cables
and wires at least 3 feet from televisions or
radios to prevent static or image distortion.
Depending on the radio waves, 3 feet may
not be enough to eliminate all interference.
