Installation Procedures
Installation of drain hose
Connection of indoor drain hose
1. Please use the accessory - drain hose to connect the indoor unit's water outlet and PVC pipe.
Use snap rings to tighten them, as shown in the following figure:
2. Please use rigid PVC adhesive for the connection of other pipes and ensure there is no leakage.
3. Wrap the drain hose with insulation sleeve and tighten it with a strap to prevent air leakage in
producing condensate.
4. To prevent water from flowing back into the air conditioner after it stops running, drain hose
should decline to the drainage side with a declination of above 1/100. Drain hose expansion or
water accumulation should be prevented to avoid abnormal noise.
5. The pipe connections will become loose or come off if you pull them while connecting the drain
hose . Avoid pulling out the drain hose laterally for more than 20cm. It should be supported every
0.8-1.0m to avoid bending.
6. The end of the drain hose should be more than 50mm away from the ground or the bottom of the
drainage tank. It should not be put in water. To directly drain condensate into the drainage ditch,
the drain hose must be U-shaped to avoid stink spreading through the room.
