1.9 Installation Requirements of Indoor Unit
1) CEILING HOLE AND THE HOOKINSTALLATION
Preparation Work on the Ceiling
Installation methods should be changed under the different construction structure. Please consult the
professional for the detailed information. After opening a hole, the ceiling should be horizontal and strong to
prevent vibration. Cut the beams at the hole and remove them . Reinforcing the beams that have been cut and
the beams fixing the ceiling .Installation of the hanging screw bolt. Bolt with M10 whorl is to be used. The
center distance between the bolts is decided by the size of the unit. Use the following method to install:
Wooden construction
Put the square timber over the roof beam, then install the hanging screw bolts.
For finished concrete bricks
Install the hanging hook with expansible bolt into the concrete deep to 45~50mm to prevent loose.
New Concrete Bricks
Inlaying or embedding the screw bolts.
Steel roof beam structure
Install the supporting angle steel.

Overhanging the indoor unit
Adjust the gasket (down side) to 90mm over the ceiling.
Install the hanging bolt into T groove of the hanging tool. Overhang the indoor unit and
ensure it is level using a level in dicator.

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)

Drainage Upward
To make sure that the drainage pipe would not be slanteddownward, lead it upward to a
height 360mmmaximum,then downward lead it.
Drainage Test
Check whet her the drain pipe is unhindered before testing.
1) Stow water from sprue to check.
2) Stow 600cc water with pot or hose from sprueslowly , preventing touchng the drain pump motor.
3)
After the preparation work , disconnect the water level switch ,power 20‐240VAC to of terminal board,
and the drain pump start up immediately.
4)
After drain pump run 2 min.,reset he water level pin, and t e drain pump motor will stop after running 1
min..
