Installation Manual
Connecting drain pipe
The following materials for piping work and insulating process are procured locally.
REQUIREMENT
• Using adhesive agent for vinyl chloride, connect the hard vinyl chloride pipes certainly so that water does not leak.
• It requires several times to dry and harden the adhesive agent.
(Refer to Guide Manual of the adhesive agent.)
In this time, be sure not to apply force to the connecting section with the drain pipes.
Piping method
Drain and refrigerant pipes can be drew out from left, right, back or bottom depending on the installation location.
However, drain pipes can be drew out from left only when the refrigerant pipes are drew out from left. The drain
hose must be fix to the refrigerant pipe with banding band and installed with gradient of 1/100 or more. The drain
hose end connected to the indoor unit must be free from external force.
• Do not route the drain hose and refrigerant pipes on the electrical control box. Dew condensation water from
pipes may enter into the electrical control box and it may cause malfunction. Exclude AP015 to AP027 model.
• Keep the drain hose and refrigerant pipes clear of the electrical control box 5 mm or more on AP015 to AP027
model. If the clearance is less than 5 mm, drip-proof cover cannot be removed and the electrical control box
cannot be took out.

Check the draining
• After piping work, remove the air intake grille and pour water in the drain pan to check water drain and water
leakage from connecting part of the drain hose.
• After check of the water drain, attach the air intake grille as before.
Fix the drain hose to the refrigerant pipe
with binding bands without hanging down
and slack. fix 3 points
Do not bind the drain hose and refrigerant
pipe (heat insulator) too tight.
