Outdoor Unit Installation Instructions
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. Ensure the awning 
does not obstruct airflow.   
 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. 
 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, DO NOT install 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. 
(See Fig. 5.1 & 5.2)   
 Install the indoor and outdoor units, cables 
and wires at least 1 meter from televisions or 
radios to prevent static or image distortion. 
Depending on the radio waves, a 1 meter 
distance may not be enough to eliminate all 
interference.
