Checking the Drainage
After wiring and drain piping are completed, use the
following procedure to check that the water will drain
smoothly. For this, prepare a bucket and wiping cloth
to catch and wipe up spilled water.
(1)
Connect power to the power terminal board (L1,
L2 terminal) inside the electrical component box.
(2)
Remove the tube cover and through the opening,
slowly pour about 1,200 cc of water into the drain
pan to check drainage.
(3)
Short the check pin (CN5 white) on the indoor
control board and operate the drain pump. Check
the water flow and see if there is any leakage.
Be careful since the fan will
start when you short the pin
on the indoor control board.
(4)
When the check of drainage is complete, open
the check pin (CN5 white) and remount the tube
cover.
To mount the tube cover,
use 4 x 8 tapping screws.
(Fig. 3-32)
Do not use long screws as
they may puncture the drain
pan and cause water
leakage.
