CAUTION

●In cases where it is necessary to raise the height of the drain piping, the drain piping can be raised

Xto a maximum height of 33-15/32" above the bottom surface of the ceiling. Under no conditions attempt to raise it higher than

33-15/32" above the bottom surface of the ceiling. Doing so will result in water leakage. (Fig. 3-9)

●Do not install the pipe with an upward gradient from the connection port. This will cause the drain water to flow backward and leak when the unit is not operating. (Fig. 3-10)

●Do not apply force to the piping on the unit side when connecting the drain pipe. The pipe should not be allowed to hang unsupported from its connection to the unit. Fasten the pipe to a wall, frame, or other support as close to the unit as possible. (Fig. 3-11)

●Provide insulation for any pipes that are run indoors.

3-5. 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)Slowly pour about 0.3 gal of water into the drain pan to check drainage. (Fig. 3-12)

(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.

CAUTION	Be careful since the fan will
	start when you short the pin
	on the indoor control board.
