INSTALLATION INSTRUCTIONS
Drain Pipes
Requirements:
• The drainpipe of the indoor unit should be heat-insulated.
• Heat insulation should be treated for the connection with the indoor unit. Improper heat insulation may cause
condensing.
• Condensate drains must have a pitch greater than 1/100 and have a minimal amount of direction changes or abnormal
noise will be created.
• The horizontal run of the condensate line should be less than 66 feet (20 m). Long runs of drain line must be supported
every 5 to 6.5 feet (1.5 ~ 2m) to prevent sags.
• The central piping should be connected according the following drawing.
• Take care not to apply external force on the connection of the drainpipes.

Piping Materials & Heat Insulating Materials:
As avoid condensation, heat insulating material should be
installed. The heat insulating treatment for piping should be
done respectively.
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.
