ELECTING INSTALLATION SITE
Make sure to provide for adequate measures in order
to prevent that the outdoor unit be used as a shelter
by small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
1.
Select an installation site where the following conditions are satisfied
and that meets with your customer's approval.
•
Places which are well-ventilated.
•
Places where the unit does not bother next-door neighbours.
•
Safe places which can withstand the unit's weight and vibration
and where the unit can be installed level.
•
Places where there is no possibility of flammable gas or product
leak.
•
Places where servicing space can be well ensured.
•
Places where the indoor and outdoor units' piping and wiring
lengths come within the allowable ranges.
Precautions
Do not install or operate the unit in rooms mentioned below.
Where mineral oil like cutting oil is present.
Where the air contains high levels of salt such as that near the
ocean.
Where sulphurous gas is present such as that in areas of hot
spring.
Where voltage fluctuates a lot such as that in factories.
In vehicles or vessels.
Where high concentrations of oil vapour or spray are present
such as that in kitchens.
Where machines generating electromagnetic waves are
present.
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 150 mm 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 accumulating
on the rear fins.
5.
If you install the unit on a building frame,
please install a waterproof plate (within
150 mm of the underside of the unit) in
order to avoid the drainwater dripping. (See
figure).
P
RECAUTIONS 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.
Unpacking and placing the unit
•
Remove the wooden crate from the unit.
•
Remove the 4 screws fixing the unit to the pallet.
•
The unit must be installed on a solid longitudinal foundation
(steelbeam frame or concrete). Maximum height of the foundation
is 150 mm.
•
Lift the unit from the pallet and place it on its installation position.
