CAUTION
(Please note the following matters and obtain permission from customer before installation).
The outdoor unit must be mounted at a location which can support
●
heavy weight. Otherwise, noise and vibration will increase.
Selecting the installation location: Suitable location that will reduce the
●
impact from rain and direct sun that may affect the unit performance.
Besides that, ventillation must be good and clear of obstruction.
The air blown out of the unit should not point directly to animals or plants.
●
The clearances of the unit from top, left, right, front and back are specifi ed
●
in fi gure below. At least 3 of the above sides must be open air.
Be sure that the hot air blown out of the unit and noise do not disturb
●
the neighbourhood.
Do not install at a location where there is fl ammable gas, steam, oil and
●
smoke.
The location must be convenient for water drainage.
●
Place the outdoor unit and its connection wire at least 1m away from the
●
antenna or signal line of television, radio or telephone. This is to avoid
noise interference.
Direction of Piping
Do not install outdoor unit facing strong wind direction. It may damage
●
the fan motor.
Horizontally
Do not install the outdoor unit in a place where small animals may build

INSTALLATION OF REFRIGERATING PIPES AFTER CONNECTION
●
The refrigerating pipes should be adjusted to fi t into the

cover. (Refer to "CONNECTION OF POWER CORD")
●
After adjustment, fi t the connecting cord and pipes into
the space available under the indoor unit.
●
When connection is at left side, refrigerating pipe and
cabinet shall be tied together.
Failing to do so may cause the unit bottom side become
warping.
Excess binder shall be cut to prevent abnormal sound
and water dripping.
