the weight of the unit.
3. Where the drain pipe can be easily connected to outside.
4. Where the flow of the air inlet/outlet is not blocked.
5. Where the refrigerant pipe of the indoor unit can be easily led to outside.
6. Where there is no inflammable、explosive substances or their leakage.
7. Where there is no corrosive gas、heavy dust、salt mist、smog or moisture.
● 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.

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.
