Checking the Drainage

CAUTION
After wiring (refer to 1-10. Electrical 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 L of water into the drain pan to
check drainage.

(3) Short the check pin (CHK) (6P : 5-6) 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.
* If the check pin (CHK) (6P:5-6) is shorted, the fan starts
rotating at high speed and could cause injury.
(4) When the check of drainage is complete, open the check
pin (CHK) (6P : 5-6) and remount the tube cover.
(5) Checkpoint after installation
After installation of indoor and outdoor units, panels
and electrical wiring, check the following items.
Be careful since the fan will start
when you short the pin on the
indoor control board.

fire.
(5) Connect the wires into the terminals through the power
supply inlet for the electrical component box.
