8.4. Check of Drainage
•
At the of trial run, ensure the water is being properly drained out and
that no water is leaking from joints.
•
Always make this check at the time of installation during other air-
conditioning (cooling) season.
•
Similarly, check it also before finishing the ceiling of new premises.
(1) Remove the cover of water supply inlet, and fill in about 1000 cc of
water, using water supply pump, etc. While filling water, ensure that it
is not sprayed into the internal drain lift up mechanism.
(2) Confirm that water is being drained out through the drainage outlet,
after switching over from remote control mode to trial run mode.
(3) After checking, fit back the cover without fail, and cut off the main power
supply switch.
(4) When installing during other than air-conditioning out the water. After
confirming that water drains out, fit back the drain plug.
