C. Precautions on Installation of Outdoor Unit
To ensure the unit in proper function, an installation location must be selected in accordance with the following
principles:
(1)
Outdoor unit should be installed in a way that the air discharged from the outdoor unit will not return and
sufficient space for repair can be provided around the machine.
(2)
The installation site must be sufficiently ventilated, so that the outdoor unit can take in and exhaust
enough air. Ensure no obstacle at the air intake and exhaust of the outdoor unit. If there is, remove it.
(3)
Place of installation should be strong enough to withstand the outdoor unit, and it should be able to
insulate noise and prevent vibration. Ensure that the wind and noise from the unit not affect your
neighbors.
(4)
Avoid direct sunshine over the unit. It is better to set up a sun shield as protection.
(5)
Place of installation must be able to drain the rainwater and defrosting water.
(6)
Place of installation must ensure the machine not be buried under snow or subject to the influence of
rubbish or oil fog.
(7)
The installation should be done where the air exhaust outlet does not face strong wind.
