Drain test
The air conditioner uses a drain pump to
drain water.
Use the following procedure to test the
drain pump operation:
- Connect the main drain pipe to the exterior
and leave it provisionally until the test
comes to an end.
- Feed water to the flexible drain hose and
check the piping for leakage.
- Be sure to check the drain pump for
normal operating and noise when electrical
wiring is complete.
- When the test is complete, connect the
flexible drain hose to the drain port on the
indoor unit.
