Installation Procedures
Attention
• For normal drainage, the water drainage piping should be connected according to the installation manual. Heat
insulation should be performed to avoid condensation. Improper pipe connection may cause water going into the
machine.
Requirements:
• Heat insulating treatment should be made for the water drainpipes of the indoor units.
• Heat preservation should be made for the connection with the indoor units. Improper heat preservation may cause
condensing.
• The drainpipe should be designed with a down gradient of 1/100. The midway of the elbow shouldn't be made in S
shape. Or abnormal noise may be caused.
• The lateral length of the drainpipe should be kept within 20m. Under the condition of long pipe, a support should be
provided every 1.52~2m to avoid unevenness.
• The central piping can be connected according the following gure.
• Don't apply external force to the connection of drainpipes.

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.
Conrming water drainage
During the test run, check the condition of water drainage and make sure that there is no leakage on the connection of
piping, which should also be performed during the winter.
Hose
The drainage hose is made of Ø19.05mm (3/4") PVC tube, which can adjust the eccentricity and the 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.
Piping Material Hard PVC tube VP31.5mm(inner bore)
Heat Insulating Material Vesicant polythene thickness: over 7mm
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
