Drain Piping

CAUTION
Following the Installation Manual, perform the drain piping work so that water is properly drained. Apply a heat
insulation so as not to cause a dew condensation.
Inappropriate piping work may result in water leakage in the room and wet furniture.
• Provide the indoor drain piping with proper heat insulation.
• Provide the area where the pipe connects to the indoor unit with proper heat insulation. Improper heat insulation
will cause condensation to form.
• The drain pipe must be sloping downward (at an angle of 1/100 or more), and do not run the pipe up and down
(arched shape) or allow it to form traps. Doing so may cause abnormal sounds.
• Restrict the length of the traversing drain pipe to 20 meters or less. For a long pipe, provide support brackets at
intervals of 1.5 to 2 meters to prevent flapping.
• Install the collective piping as shown in the following figure.
• Do not provide any air vents. Otherwise, the drain water will spout, causing water to leak.
• Do not allow any force to be applied to the connection area with the drain pipe.

Pipe material, size and insulator
The following materials for piping work and insulating process are procured locally.
Pipe material Hard vinyl chloride pipe VP25 (Nominal outer diameter Ø32mm)
Insulator Foamed polyethylene foam, thickness: 10mm or more
Connecting drain pipe
Insert the drain hose into the connector until the hose can go no farther.
REQUIREMENT
• Connect the hard vinyl chloride pipes certainly so that water does not leak by using adhesive agent for vinyl chloride.
• It takes some time to dry and indurate the adhesive agent. (Refer to the manual of adhesive agent.) Do not apply any
extra force on the connecting section until the adhesive agent dried.
