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.
Confirming water drainage
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.
Attention
Hose
The drainage hose is made of 19.05mm (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.
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
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.
Requirements:
1.5m~2m
support
heat
insulating
material
down gradient of over 1/100
S-shape elbow
VP30
max. height (about 10cm)
down gradient
of over 1/100
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 figure.
Don’t apply external force to the connection of drainpipes.
