To prevent exposure to wind, install the outdoor unit with its
suction side facing the wall.

Never install the outdoor 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 outdoor unit.

In heavy snowfall areas it is very important to select an
installation site where the snow will not affect the unit and set the
outlet side at a right angle to the direction of the wind:
1 Construct a large canopy.
2 Construct a pedestal.
Install the unit high enough off the ground to prevent
burying in snow.

RECAUTIONS ON INSTALLATION
6.1. Foundation work
When installing the outdoor unit, please refer to "5. Selecting
installation site" on page 6 to select an appropriate location.
1 Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
2 Prepare 4 sets of M8 or M10 foundation bolts, nuts and washers
each (field supply).
3 Fix the unit securely by means of the foundation bolts in
accordance with the foundation drawing.
It is best to screw in the foundation bolts until their length are
20 mm from the foundation surface.
6.2. Drain work
General
Assure that drain water coming from the outdoor unit during heating
operation and defrost operation can be properly evacuated.
■
Install the unit on a base that can assure a proper drainage in
order to avoid ice accumulation.
■
A drain channel can be foreseen under the unit. Be sure that
drain water in this drain channel does not freeze causing
blockage by ice accumulation.
■
Avoid drain water flowing over the footpath, so that in case of
ambient freezing temperatures the footpath does not become
slippery.
NOTICE
When operating the outdoor unit in a low outdoor ambient
temperature, be sure to follow the instructions described
