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
(L1, L2 terminal) inside the electrical component
box.
(2)
Remove the insulator and drain cap from the
drain inspection port, insert the supplied elbow,
and connect it using the supplied clamp
(Fig. 3-17).
(3)
Pour water into the opening of the elbow up to the
marked level. Excess water will be prevented by
a drainage hole.
(4)
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.
(5)
Drainage is normal if the water gradually drops
from the marked level.
(6)
When the check of drainage is complete, open
the check pin (CN5 white) and remount the
insulator and drain cap onto the drain inspection
port.
