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.
Lifting Drainpipe
The drainpipe can be lifted 360mm.
When the down gradient of the drainpipe can't be ensured,
after upright lifting, the drainpipe is in the down slope.

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 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

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. Don't add water to the motor of the drainage pump.
• After mounting the electrical system, do cooling operation and meanwhile add
water and check.
• If the electrical installation hasn't 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.
