4.3.3 Test of Drainage System 

(1)  Please test drainage system after electric work is finished. 

Inject approximately 1L purified water to drain pan from air vent, ensure that not to splash the 

water over the electrical components (e.g. water pump. etc.). 

1)  In case of commissioning finished, please energize the IDUs and switch to cooling or 

dry mode, meanwhile, the water pump operates, you can check the draining through 

the transparent part of drain socket. 

2) 

If communication wire is not connected, communication malfunction “C0” will occur 

after 60s of energizing. In this case, the water pump operates automatically. Check if 

the water pump drains normally drains normally through drainage port. The water 

pump will stop automatically after running for 10min. 

(2)  During the test, please carefully check the drainage joint, make sure no any leakage occur. 

(3)  It is strongly recommend to do the drain test before ceiling decoration.

4.4 Installation of Air Duct 

Note! 

 There should be insulating layer on air-out duct, air-return duct and fresh air duct to 

avoid heat loss and moisture. Adhere a nail on the air duct and then add thermal 

sponge with a layer of tin. Fasten it with a nail cover and then seal the junction with  tin 

tapes.You can also use other materials that have good insulation quality.  

 Each air-out duct and air-return duct should be fixed on a pre-made board with iron 

frame. The junction of air duct should be well-sealed in order to prevent air leakage. 

 The design and construction of air duct should comply with national requirements.  

 The edge of air-return duct is suggested to be more than 150mm (5-7/8 in.) away from 

the wall. Add a filter to the air-return opening. 

 Please consider noise-damping and vibration damping for the design and construction 

of air duct. Besides, noise source must be away from people. For instance,  do not have 

the air-return opening installed on top of the user (offices, rest area, etc.).
