Requirements:
■
The drainpipe of the indoor unit should be heat-insulated.
■
Heat insulation should be treated for the connection with the indoor unit. Improper heat insulation may cause
condensing.
■
The drainpipe with the down gradient of over 1/100 can't be in the S shape, or abnormal sound can be caused.
■
The horizon length of the drainpipe should be kept with 20m. Under the condition of long pipes, supports can be
provided every 1.5~2m as to avoid unevenness.
■
The central piping should be connected according the following drawing.
■
Take care not to apply external force on the connection of the drainpipes.

■
For proper drainage, the drainpipes should be connected according to the installation manual. Heat preservation
should be performed as to prevent condensing. Improper connections may cause the water leakage.
Attention
Piping Materials & Heat Insulating Materials
As to prevent condensation, heat insulating treatment should
be performed. The heat insulating treatment for piping should
be done respectively.

Hose
The attached hoses can be used to adjust the eccentricity and angle of the hard PVC tube.
■
Stretch the hose directly to make connections as to avoid distortion. The soft end of the hose should be
positioned with a clamp.
■
The hose should be used in the horizon direction.

Heat Insulating Treatment:
■
Wrap the connection between the clamp and the root segment of the indoor unit without any gap with heat
insulating materials as shown in the drawing
