Installation Procedures
•
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 done for the water drainpipes of the indoor units. Heat preservation should be made
l
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
l
shape or abnormal noise may occur.
The lateral length of the drainpipe should be kept within 20m. Under the condition of a long pipe, support should be
l
provided every 1.5 ~2m to avoid unevenness.
The central piping can be connected as per the following figure.

Don't apply external force to the connection of drainpipes.

Piping Materials & Heat Insulating Materials
To prevent condensation, heat insulating
treatment should be performed. The heat
insulating treatment for piping should be
also done simultaneously.
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 to avoid distortion. The soft end of the hose should be positioned with a
l
clamp.
The hose should be used in the horizontal direction.
l
Heat Insulating Treatment:
Wrap the connection between the clamp and the root segment of the indoor unit without any gap with heat insulating
l
materials as shown in the drawing
Confirming waterdrainage
During the test run, check the condition of water
drainage and make sure that there is no leakage
on the connection of the piping. Repeat the check
during winter again.
