Precautions
•
Do not install or operate the unit in rooms mentioned below.
a. Where mineral oil like cutting oil is present.
b. Where the air contains high levels of salt such as that near
the ocean.
c. Where sulphurous gas is present such as that in areas of

e. In vehicles or vessels.
f. Where high concentrations of oil vapour or spray are
present such as that in kitchens.
g. Where machines generating electromagnetic waves are
present.
h. Where acidic or alkaline vapour is present.
2. Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.
3. If you install the unit on a frame, please install a waterproof
plate within 150mm of the underside of the unit in order to
prevent the invasion of water from the lower direction.
4. When installing the unit in a place frequently exposed to
snow, pay special attention to the following:
•
Elevate the foundation as high as possible.
•
Remove the rear suction grille to prevent snow from accu-
mulating on the rear fins.
5. If you install the unit on a building frame, please install a
waterproof plate (within 150mm of the underside of the unit)
in order to avoid the drainwater dripping. (See figure).

•
Unpacking and placing the unit
a) Remove the wooden crate from the unit.
b) Remove the 4 screws fixing the unit to the pallet.
c) The unit must be installed on a solid longitudinal founda-

foundation is 150mm.
d) Lift the unit from the pallet and place it on its installation
position.

In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four

are available on the market.)
•
It is best to screw in the foundation bolts until their length are
20mm from the foundation surface.
