Heat pump installation notes

1)

The heat pump must be installed in open space. Normally is installed on the 
roof of house. 

2)

The unit should be placed in dry and well-ventilated environment. If the 
environment is humid, electronic components may get corroded or short circuit.

3)

Heat pump mustn’t be installed in the environment where corrosive, volatile, or 
flammable liquid or gas exists. 

4)

Because of the noise is a little loud, please don’t install the heat pump near 
bedroom or living room or meeting room. 

5)

The bottom of the heat pump should be at least 50cm higher than ground, 
because rain water, snow may enter inside if the installation is on ground. 

        Heat pump can be installed on concrete basic or steel support. 
6)

Please install a shed for the heat pump, otherwise, rain water can reduce the 
lifetime of the shell, and snow may cover the air outlet. 

7)

Water drainage ditch should be set around the heat pump, when heat pump is 
working, there is condensing water flow down, or when defrosting, there are 
plenty of water flow down too. 

8)

Heat pump should far away from kitchen exhaust, because the finned tube is 
not easy to clean if there is oil on it.
