INSTALLATION CLEARANCE
Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air
Á
ow.
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
Á
ow out. Insert the drain elbow to one of the
holes.
To install the drain elbow,
À
rst 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
À
rmly.
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.

REFRIGERANT PIPING
Maximum Allowable Pipe Length and Elevation
If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to
Á
ow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective.
Always choose the shortest path and follow the recommendation as tabulated below.

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.
