Please according to the tube hardness to choose proper
support density, do not appear obvious dropping and
deformation situation. Dropping part will save the water and
lead to poor drainage and abnormal noise.

Drainage system design requirement
Drainage pipe can use PVC pipe, recommended to use the
pipe of 25 mm inner diameter, water pipe should has thermal
insulation layer.
The user can purchase the pipe of suitable
length in the dealer place or in a local after-sale service
center place, or directly to purchase in the market.
Insert the drainage pipe port to the condensate water outlet,
and use the outlet clamp (accessory) to fasten the drainage
pipe and the thermal insulation sleeve.
The pipes are needed to be packed with insulation heat
preservation material. The connection of water pipe and air
conditioner should use insulating sheath package, and
tighten tightly to prevent water condensation to damage the
ceiling decoration.
To avoid water poured into the air conditioner inside when the
unit operation stops, drainage pipe should be down dipped to
outdoor side (drainage side), gradient is more than 1/100,
drainage pipeline can not occur bending and dropping save
water phenomenon, otherwise it will cause abnormal noise.
During connecting pipe, please do not force pulling the
drainage pipe which will cause the nozzle loose, and at the
same time shall set up enough strong points, in order to avoid
the drainage pipe drops.
Drainage test
After the unit installation then do the trial run and water
the cooling mode and do the water drainage test.
Open the cover of water test hole, use bottle or flexible pipe
to fill water (500ml/min.), and then to observe whether has
water drain out from the water drainage port. Check
whether the pipeline has leakage and places which not pack
with thermal material, and improve the parts with problems.
After finishing water drainage and power off the unit, install
back the cover of water test hole.

7. INSTALL THE CONNECTING PIPE
The connective length of indoor and outdoor piping and those
height difference requirements.
Connect to different outdoor units with different connective
length and height difference requirements. Please refer to
Indoor Unit Installation Manual for detail.
Do not let air, dust, or other impurities fall in the pipe system
during the time of installation.
The connecting pipe should not be installed until the indoor and
outdoor units have been fixed already.
Keep the connecting pipe dry, and do not let moisture in during
installation.
The Procedure of Connecting Pipes
Measure the necessary length of the connecting pipe, and make
it by the following way.
Gutter
Fig.6-4
Connect the indoor unit at first, then the outdoor unit.
Bend the tubing in proper way. Don't harm them.
1
Daub the surfaces of the flare pipe and the joint nuts with frozen
2
oil, and wrench it for 3~4rounds with hands before fasten the
flare nuts. (Refer to Fig.7-1)
Be sure to use two wrenches simultaneously when you connect
3
or disconnect the pipes.
The stop valve of the outdoor unit should be closed absolutely
(as original state). Every time you connect it, first loosen the nuts
at the part of stop valve, then connect the flare pipe immediately
(in 5 minutes). If the nuts have been loosened for a long time,
dusts and other impurities may enter the pipe system and may
cause malfunction later. So please expel the air out of the pipe
with refrigerant before connection.
Expel the air (refer to the "Expel The Air") after connecting the
refrigerant pipe with the indoor unit and the outdoor unit.Then
fasten the nuts at the repair-points.
Notices For Benable pipe.
The bending angle should not exceed 90
Bending position is preferably in the bendable pipe. The larger
the better it is .
Do not bend the pipe more than three times.
Bend the connecting pipe of small wall thickness.
Cut out a desired concave at the bending part of the insulating
pipe.
Then expose the pipe(cover it with tapes after bending).
To prevent collapsing of deforming, please bend the pipe at its
biggest radius.
Use bender to get a small radius pipes.
Use the market brass pipe.
Be sure to use the same insulating materials when you buy the
brass pipe. (More than 9mm thick)
The temperature of refrigerant circuit will be high, please keep
the interconnection cable away from the copper tube.
