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.
Piping
Material
Heat Insulating
Material
Hard PVC tube VP31.5mm
(inner bore)
Vesicant polythene
thickness: over 7mm
Hose
The attached hoses can be used to adjust the eccentricity and 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 lateral 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
Lifting Drainpipe
The drainpipe can be lifted 360mm.
When the down gradient of the drainpipe cant be ensured, after upright
lifting, the drainpipe is in the down slope.
Confirming Drainage
The drainage should be confirmed during the test run to make sure that there is
leakage at the connection.
The confirmation of drainage should be also performed during the installation in
the winter season.
Fill water from the outlet or the specified position and confirm the drainage.
Fill 600cc water with a hose from the outlet or the specified location on the machine.
Add the water slowly. Dont add water to the motor of the drainage pump.
After mounting the electrical system, do refrigerating operation and meanwhile
add water and check.
If the electrical installation hasnt been completed, pull out the terminal(2P)
of the floater switch on the electrical cabinet. After confirming the drainage,
connect the terminal of the floater switch and run the drainage pump for 5
minutes until it stops automatically.
Confirm the sound of the motor:
Confirm the sound of the motor of the drainage pump and meanwhile check
the drainage.
