INSTALLATION INSTRUCTIONS

Installation of drain hose

Connection of indoor drain hose. Place with air inlet opening
1. Please use the accessory drain hose to connect indoor unit's drain outlet to a PVC drain line. Use clamps to tighten
them as shown in the following figure:
2. Please use rigid PVC glue for connection to PVC pipes and ensure there is no leakage.
3. Drain hose must be wrapped with insulation sleeve and tightened with a strap to prevent air leakage from producing
condensate.
4. To prevent water flowing back into air conditioner when the unit stops running, drain hose should decline to the
drainage side with an inclination of above 1/100. Drain hose expansion or water accumulation should be prevented, or
else it will cause abnormal noise.
5. When connecting the drain hose, do not pull on it to avoid the pipe connections from getting loose or disconnected.
Drain hose should not be pulled out laterally for more than 8in (200mm) and should be supported every 31-39in
(0.8- 1.0m) to avoid bending.
6. The end of drain hose should be more than 2in (50mm) away from the ground or the bottom of drainage tank. It should
not be put in water. To directly drain condensate into drainage ditch, the drain hose must be trapped to avoid odors
from entering through the hose into room.

Drainage Test:
Ensure the drain hose is clear and all connections are tightly sealed before testing.
Perform the drainage test as follows:
1. Add about 0.132gal (500ml) of water into the drain pan through water injection port.
2. Switch on the power and operate the unit in cooling mode. Check that the water outlet drains water normally and that
there are no leakages at the connections. After the drainage test is complete, replace the water injection port plug. For
the position of water injection port; see the figure:
