Drain piping
CAUTION
Condensate drain piping installation and material must comply with applicable codes and regulations for the
specific indoor installation.
The condensate drain piping must be insulated to prevent sweating. All material used in the plenum space above
the ceiling must comply with applicable codes and regulations. If the condensate drain exits the unit downward
(gravity flow) the slope and suspension methods used for the condensate drain piping must comply with applicable
codes and regulations.
• 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 65.6' (20 m) or less. For a long pipe, provide support brackets
at intervals of 4'11" to 6'7" (1.5 to 2 m) 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.

Connecting drain pipe
Insert the drain socket into the connector until the socket 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.
