2-5. Checking the Drainage
After wiring and piping are completed, use the follow-
ing procedure to check that the water will drain
smoothly. For this, prepare a bucket and wiping cloth
ready to catch and wipe up spilled water.
Do not supply power to the
unit until the tubing and
wiring to the outdoor unit
are completed.
(1) Take off the tube cover and through the opening,
slowly pour about 1,200 cc of water into the drain
pan to check drainage.
(2) Do Test Run to check the drainage after complet-
ing installation. When performing Test Run, be
sure to observe the Test Run procedure.
Be careful since the fan will
start turning when checking
the drainage.
(3) After drain checking is finished, return the
Operation Selector switch to the RUN position
(ON position
) and remount the tube cover.
To mount the tube cover,
use 4

not use long screws as they
