3-4. 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 (R, S
terminals) inside the electrical component box.
(2) Pour water into the drain pan about 500 cc using a
siphon pump through the air outlet grille.
(Fig. 3-16)
(3) Short the check pin (CHK) on the indoor control
board and operate the drain pump. Check the
water flow through the transparent drain pipe and
see if there is any leakage.
(4) When the drainage check is complete, open the
check pin (CHK) and remount the insulator.
CAUTION
CAUTION
Be careful since the fan will
start when you short the
pin on the indoor control
board.
The bottom drain port is for
use only during test runs
and servicing inspections.
Do not connect the drain
pipe to the bottom drain
port.
