refrigerant pipe on the liquid-side and the gas-
side. Ensure that there is no gap between them.
Incomplete insulation may cause water
condensation.

10. CONNECT THE DRAIN PIPE

1. Install indoor unit drain pipe
The outlet has PTI screw bread, Please use
sealing materials and pipe sheath (fitting) when
connecting PVC pipes.
CAUTION
• The drain pipe of indoor unit must be heat
insulated, or it will condense dew, as well as the
connections of the indoor unit.
• 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.
• When the declivity of the drain pipe downwards
is over 1/100, there should not be any win ding.
• The total length of the drain pipe when pulled out
traversely shall not exceed 20m, when the pipe is
over long, a prop stand must be installed to
prevent winding.
• Refer to the figures on the right for the
installation of the pipes.
2. Drainage test
Check whether the drainpipe is unhindered
New built house should have this test done before
paving the ceiling.
