Matching of the indoor and outdoor units

Power source

WARNING!

Combinations those marked * can not be applied where the temperature in winter is too low and in
summer is too higher to avoid bad heating or cooling effect.

2.Selecting a location for installation of the indoor units

The maxinum allowable length of refrigerant piping, and the maxmum allowable height
difference between the outdoor and indoor units, are listed below.
(The shorter the refrigerant piping, the better the performance. Connect so that the
piping is as short as possible. Shortest allowable length per room is 3m)

1.Precautions on installation

Check the strength and level of the installation ground so that unit will not cause any operating vibration
or noise after installation.
In accordance with the foundation drawing in fix the unit securely by means of the foundation bolts.
It is best to screw in the foundation bolts unit their length are 20 mm from the foundation surface.
