2) DRAINA GE PIPE INSTALLATIO N
CAUTION
The drain pipe of indoor unit must have the heat insulation , or it will condense dew, as well as the connections of the
indoor unit. The declivity of the drain pipe downwards should be over 2/100, and no winding and bending. The total
length of the drain pipe when pulled out traversely should not exceed 20m , when the pipe is over long, a prop stand
must be installed every 1.5 to 2m to prevent winding. Refer to the following figures about the installation of the pipes.
Do not impose any pr essure on the connection part of the drainage pipe .
Drainage Pipe Material, Heat‐insulating Material
The listed material should be used:
Drainage Pipe Material Polyvinyl c hloride pipe (f32mm outer diameter)
Heat Insulation Material Foamed po lyethylene insulation plate (10mm thick ness)
Flexible Hose
Measure diameter of the hard pipe using cutting method, and adjust the joining angle. Pull out the flexible hose,
do not over deform than illustrated below. Be sure to bind it with the attached band. Ple ase place the flexible
hose horizontally.
Connection Procedure
Connect the transparent pipe with the polyvinyl chloride pipe. Use polyvinyl chloride glue at the conn ection
part of the drain age pipe, be sure no water leakage.Paste glue at the front 40m m of the polyvinyl chloride pipe,
insert it into the transparent pipe. It needs 10 minutes for the glue to dry. Do not impose pressure on the
connection during the drying period.
Heat Insulat ion
Wrap the fle xible hose carefully with the attached heat insulation material rom the start to the end (to
indoor part)
