How to select the installation location for the outdoor unit
1. The outdoor unit must be installed where the bearing surface is stable and secure enough.
2. The outdoor unit and indoor unit should be placed as close as possible to minimize the length and bends of the refrigerant
pipe.
3. Do not install the outdoor unit under the window or between the buildings to prevent the normal running noise entering the
room.
4. Where the flow of the air inlet/outlet is not blocked.
5. The outside unit should be installed where ventilation is in good condition so that the unit can take in and discharge
enough air.
6. Do not install the unit where there are inflammable and explosive substances and where there is heavy dust
、
salt fog and
other severely polluted air.
No air guiding pipe is allowed to be installed at the air inlet/outlet of the outdoor unit.
Under the heating mode, the condensate water would drip down from the base frame and would be frozen when the outdoor
ambient temperature is lower than 0°C (32°F). Besides, the installation of the outdoor unit should not affect the heat radiation of the
unit.
