INSTALLATION CLEARANCE
Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air flow.
Select the coolest possible place where intake air should not be hotter than the outside temperature (refer to operating
range).

Condensed Water Disposal Of Outdoor Unit
(Heat Pump Unit Only)
There are 2 holes on the base of Outdoor Unit for condensed
water to flow out. Insert the drain elbow to one of the
holes.
To install the drain elbow, first insert one portion of the
hook to the base (portion A), then pull the drain elbow in
the direction shown by the arrow while inserting the other
portion to the base. After installation, check to ensure that
the drain elbow clings to base firmly.
If the unit is installed in a snowy and chilly area, condensed
water may freeze in the base. In such case, please remove
plug at the bottom of unit to smooth the drainage.

NOTE
Be sure to add the proper amount of additional refrigerant, failure to do so may result in reduced performance.
Remark: The refrigerant pre-charged in the outdoor unit is for the piping length up to 7.5m.
REFRIGERANT PIPING
Allowable Pipe Length and Elevation
If the pipe is too long, both the capacity and reliability of the unit will drop. As the number of bends increases, resistance to
the flow of refrigerant system increases, thus lowering cooling capacity. As a result, the compressor may become defective.
Always choose the shortest path and follow the recommendations as tabulated below:
