DRAIN PIPING WORK
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.
Using a hose or a pitcher, enter 600cc-water gradually
into the air outlet taking precautions against water
splash on the motor of the drain pump.
When the electric work has finished:
• Before installing a panel, pour water, check water is drained from the drain pipe 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 from P.C. board connector (CN030: Red) of the electric parts box.
(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, 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 (CN030) of P.C. board, and then set the electric parts box as before.

• 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.
