Checking the Drainage
Be careful since the fan will start
when you short the pin on the
indoor control board.
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 (L, N
terminals) inside the electrical component box.
(2) Slowly pour about 1,200 cc of water into the drain pan to
check drainage. (Fig. 1-12)
(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 check of drainage is complete, open the check
pin (CHK) and remount the tube cover.
(5) Checkpoint after installation
