Outdoor Unit Installation Instructions
Step 1: Select installation location.
The outdoor unit should be installed in the location that meets the
following requirements:
f Place the outdoor unit as close to the indoor unit as possible.
f Ensure that there is enough room for installation and maintenance.
f The air inlet and outlet must not be obstructed or exposed to strong
wind.
f Ensure the location of the unit will not be subject to snowdrifts,
accumulation of leaves or other seasonal debris.
f The installation area must be dry and well ventilated.
f There must be enough room to install the connecting pipes and
cables and to access them for maintenance.

f The area must be free of combustible gases and chemicals.
f The pipe length between the outdoor and indoor unit may not exceed
the maximum allowable pipe length.
f If possible, DO NOT install the unit where it is exposed to direct
sunlight.
f If possible, make sure the unit is located far away from your
neighbours property so that the noise from the unit will not disturb
them.
f 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. (See Fig. 4 & 5)
f Install the indoor and outdoor units, cables and wires at least 1 metre
from televisions or radios to prevent static or image distortion.
Depending on the radio waves, a 1 metre distance may not be enough
to eliminate all interference.
