7-4. Attention for test run

 Check that the drain-up mechanism is working properly, that no water is leaking from pipe connections, and that the fan is
operating.
• For new installation, check the above items before completing ceiling work.
(1) Remove the cover from the water supply inlet on the indoor unit pipe.
(2) Insert the end of the pump or the tank into the drain pump. (Water may leak if it is not inserted properly.) Then, fill the
water supply pump from a water supply tank.
(3) Perform a test run in the Cooling mode, or connect the connector to the ON-side of the SWE on the indoor unit control
board.
(The drain pump and the fan will be forced into operation without being started from the remote controller.)

(4) Check for normal operation, stop the test run, and shut off the main power. Disconnect the connector that is connected
to the ON-side of SWE, if applicable. Connect it to the OFF-side, and then replace the cover to the water supply inlet
as it was.
