6.1 Selecting a location in cold climates
Refer to "Handling" in section “4 Before installation”
When operating the unit in cold climates, be sure to
follow the instructions described below.
■ To prevent exposure to wind, install the unit with its suction side
facing the wall.
■ Never install the unit at a site where the suction side may be
exposed directly to wind.
■ To prevent exposure to wind, install a baffle plate on the air
discharge side of the unit.
■ In heavy snowfall areas it is very important to select an installation
site where the snow will not affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is not affected by
the snow (if necessary construct a lateral canopy).
1 Construct a large canopy.
2 Construct a pedestal.
Install the unit high enough off the ground
to prevent it from being buried in snow.
NOTE
If drain holes in the unit are covered by a mounting base or
by floor surface, raise the unit in order to provide a free space
of more than 100 mm under the unit.
NOTE
Unit is top heavy!
Try not to install on the building frame.
NOTE
7 PRECAUTIONS ON INSTALLATION
■ Check the strength and level of the installation ground so that the
unit will not cause any operating vibration or noise after installation.
■ In accordance with the foundation drawing in the figure, fix the unit
securely by means of the foundation bolts. (Prepare four sets each of
Φ10 Expansion bolts, nuts and washers which are readily available on
the market.)
■ It is best to screw in the foundation bolts until their length is
20 mm from the foundation surface.

6.2 Selecting a location in hot climates
As the outdoor temperature is measured via the outdoor unit air
thermistor, make sure to install the outdoor unit in the shade, or
a canopy should be constructed to avoild direct sunlight. so that
it is not influenced by the sun’s heat, otherwise protection may be
possible to the unit.
Drain hole
The drain hole is covered by
rubber plug,if one drain hole
is not enough, the big drain
hole can be opened in field.
7 If you install the unit on a building frame, please
install a waterproof plate (field supply) (about 100
mm, on the underside of the unit) in order to avoid
drain water dripping. (See the picture in the right).
