 Connecting drain pipe
The following materials for piping work and insulating process are procured locally.
Drain pan
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 over the electrical control box. Condensed water from the pipes
may enter the electrical control box and cause malfunction. Exclude AP015 to AP027 models.
• On the AP015 to AP027 models, the drain hose and refrigerant pipes coming out of the electrical control box
must be 5 mm apart. If the clearance is less than 5 mm, it will be hard to remove the drip-proof cover and the
electrical control box can not be taken out.

*Connect and fix drain pipe at outside of the unit on site.
Install the drain hose with gradient of 1/100 or more to
connect it to unit on both left and right sides.
 Check the draining
• After piping work, gets completed, 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.
