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

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.
