7.3. Check of drainage (Fig. 7-2)
• During the test run, ensure the water is being properly drained out and that no
water is leaking from joints.
• Always check this during installation even if the unit is not required to provide cool-
ing/drying at that time.
• Similarly, check the drainage before finishing ceiling installation in a new premises.
(1) Remove the cover of the water supply inlet and add about 1/4 gal (1000 cc) of
water using a water supply pump etc. During this process, be careful not to spray
water into the drain pump mechanism.
(2) Confirm that water is being drained out through the drainage outlet, after switch-
ing over from remote control mode to test run mode.
(3) After checking the drainage, ensure that the cover is replaced and the power
supply is isolated.
(4) After confirming the drainage system is functioning, replace the drain plug.
