Leave the space reguired to service the air conditioner. (Fig.1)
(1) If a service hole is provided at the bottom of the product.
(2) If the service hole referenced in (1) is not provided.
• INSTALLING DRAIN PIPE
Position of drain piping and refrigerant piping.
The installed drain pipe should have a downward gradient of 1/50
to 1/100. Make sure that the drain pipe is installed without rises.
Use general hard polyvinylchloride pipe (VP25) and connect
it with adhesive (polyvinylchloride) so that there is no leak-
age. Do not perform air bleeding.
Main drain
On the main drain, provide one trap near the indoor unit.
Safety drain
There is no need to provide a trap for the safety drain. If the
safety drain is connected to the main drain, make the con-
nection below the main trap.
Once installation is complete, check the flow of drain water.
