INSTALLATION

 

SITE

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.

-

Places where water leaking from the unit cannot cause 
damage to the location (e.g. in case of a blocked drain pipe).

-

Places where the rain can be avoided as much as possible.

2

When installing the unit in a place exposed to strong wind, pay
special attention to the following.

Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
-

Deterioration of the operational capacity.

-

Frequent frost acceleration in heating operation.

-

Disruption of operation due to rise of high pressure.

-

When a strong wind blows continuously on the face of the 
unit, the fan can start rotating very fast until it breaks.

Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.

Turn  the air outlet side toward the building's wall, fence or
screen.

Set the outlet side at a right angle to the direction of the wind.

3

Prepare a water drainage channel around the foundation, to
drain waste water from around the unit.

4

If the water drainage of the unit is not easy, please build up the
unit on a foundation of concrete blocks, etc. (the height of the
foundation should be maximum 150 mm).

5

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.

6

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.

Take care not to let hands or objects come in contact with
rear fins.

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.
