3-12. 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) Remove the tube cover and through the opening,

slowly pour about 1,200 cc of water into the drain

pan to check the drainage.

(3) Short the check pin (CHK) on the indoor control

board and operate the drain pump. Check the

water flow through the transparent drain port 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.

(Fig. 3-47)

CAUTION

Be careful since the fan will

start when you short the

pin on the indoor control

board.

To mount the tube cover,

use 4 × 8 tapping screws.

(Fig. 3-47)

Do not use long screws as

they may puncture the

drain pan and cause water

leakage.
