2.3 Install the drainage pipe
In order to prevent faults caused by condensate of the refrigerant pipe and drain pipe, perform
condensate prevention and heat insulation properly.
Hard PVC binder must be used for pipe connection, and make sure there is no leakage.
With the connection part to the indoor unit, please be noted not to impose pressure on the side
of indoor unit pipes.
For Model 48 and 60, the outlet has PTI screw bread, so please use sealing materials and pipe
sheath (fitting) when connecting PVC pipes.
Please use the accessory drain hose to connect the outlet of indoor unit with the PVC water pipe,
and then use the accessory clasp for chucking.
To prevent water from flowing backwards into the air conditioner while the air conditioner stops,
please lean the drainage pipe down toward outdoor (outlet-side) at a degree of over 1/100. And
please avoid any bulge or water deposit.
Do not drag the drainage pipe violently when connecting to prevent the body from being pulled.
Meanwhile, one supportpoint should be set every 0.8 - 1.0m to prevent the drainage pipe from
yielding. Or you can tie the drainage pipe with the connecting pipe to fix it.
