Unit Installation Instructions Installation of Condensate Pipe
Testing of Drainage System
（１）
After the electrical installation is completed, carry out the testing of the drainage system.
(2)
During the test, check if the water correctly flows through the pipelines. Carefully
observe the joints to ensure that there is no leakage. If the unit is to be installed in a new
house, carry out testing before decorating the ceiling.

1
The standard pipe length is 5m. When the length (L) of the connecting pipe is less than or equals 5m,
there is no need to add refrigerant. If the connecting pipe is longer than 5m, it is required to add
refrigerant. In the above table, the amounts of refrigerant to be added for the models are listed for each
additional meter of pipe length.
2. The pipe wall thickness shall be 0.5-1.0 mm and the pipe wall shall be able to withstand the pressure of
6.0 MPa.
3.The longer the connecting pipe, the lower the cooling effect and the heating effect.
