When electric wiring work is not finished
• The electric wiring works (including grounding) must be carried out by a qualified electrician.
• If a qualified person is not present, after the electric wiring work is finished, check the drainage accord ing to the
method specified in [When the electric wiring work is finished].
1. Open the electrical wiring box cover and connect the ground wiring to the ground terminal.
2. Make sure the electrical wiring box cover is closed before turning on the power supply.
• Throughout the whole process, carry out the work giving caution to the wiring around the electrical wiring box so
that the connectors may not come off.
3. Gradually pour 1 litre of water from the air outlet on the left side of the drain socket into the drain pan giving caution
to avoid splashing water on the electric components such as drain pump.
4. When the power supply is turned on, the drain pump will operate. Drainage can be checked at the transparent part
of the drain socket.
(The drain pump will automatically stop after 10 minutes.)
The drainage of water can be confirmed with water level change in the drain pan through the access window.
• Do not connect the drain piping directly to the sewage that gives off ammonia odor.
The ammonia in the sewage may go through the drain piping and corrode the heat exchanger of the indoor unit.
• Do not apply external force to the float switch. (It may result in malfunction)
• Do not touch the drain pump.
Touching the drain pump may cause electric shock.
5. Turn off the power supply after checking drainage, and remove the power supply wiring.
6. Attach the electrical wiring box cover as before.
3. Sweating may occur and result in water leakage. Therefore, make sure to insulate the
following 2 locations (drain piping that laid indoors and drain sockets).
• Use the provided F sealing pad (large), and perform the thermal insulation of the A clamp metal and B drain hose
after checking the drainage of water.
