Check the draining
After drain piping work, check that water drain is
properly performed and water does not leak from the
connecting part of the pipes. In this time, check also
there is no abnormal sound of the motor of the drain
pump. Be sure to check draining when installed in the
heating period.
When the electric work has finished:
• Before installing a panel, pour water (500cc) as shown in the following figure, check water is drained from the
drain pipe connecting port in COOL mode, and then check there is no water leak from the drain pipes.
When the electric work has not finished:
• Pull out the float switch connector (2P: White). (In this time, be sure to check the power is turned off.)
• Connect the single-phase 220-240V 50Hz (or 220V 60Hz) power to the terminal blocks R (L) and S (N).
(Never apply 220-240V to (A), (B), (U1),and (U2), otherwise a trouble of P.C. board occurs.)
• When the power is turned on, the drain pump motor drives automatically. Check water is drained from the drain
pipe connecting port, and then check there is no water leak from the drain pipes.
• After check of draining and water leak, turn off the power supply, attach the float switch connector to the original
position.

Heat insulating of pipe connecting part
• Be sure to apply heat insulating securely to the pipe connecting part.
• Be sure to tape surely the butting part of the heat insulator
at the main unit side and at site so that no clearance generates.
