Installation Procedures
(f) Water trap:
Because it is easy to cause minus pressure at the water drainage hole, once the water level
in drainage pan goes up, water will leak. To prevent water leakage, we design a water trap
here.
Water trap should be easy to be cleaned. Adopt T-shape connector like below figure. It should
be near the unit,as the figure,it is set at the middle of drainage hose.
H1=100mm or fan motor static pressure

(g) Don't place the drainpipes at the places where there is irritant gas. Don't put the drainpipe
directly into the sewer, where there might be gases with sulfur.
Testing Drainage System
(a) After finishing the electrical system, test the drainage system.
(b) During testing, make sure that the water flow passes the piping correctly without any water
leakage at the connection.
(c) In the condition of new house, test the drainage system before fitting up the ceiling.
(d) Even if it is installed in the season needed to heating, the testing should also be performed.
Procedures
(a) Provide about 1000cc of water to the equipment via air outlet port with the feed pump.
(b) During refrigerating operation, check the drainage system.
