3-11. Installing the Drain Piping

(1)Prepare standard hard PVC pipe (O.D. 1-1/32") for the drain and use the supplied hose band to prevent water leaks. (Fig. 3-33)

The PVC pipe must be purchased separately.

XM	The transparent drain part on the unit allows you to
	check drainage.

(2) Installing the drain hose

● To install the drain hose, first place 1 of the 2 hose bands

over the unit drain port and the other hose band over the

hard PVC pipe (not supplied). Then connect both ends of

the supplied drain hose. (Fig. 3-33)

● On the unit drain side, grasp the hose band with pliers and

insert the drain hose all the way to the base.

● If other commercially available hose bands are used, the

drain hose may become pinched or wrinkled and there is

danger of water leakage. Therefore be sure to use the sup-

plied hose bands. When sliding the hose bands, be careful

to avoid scratching the drain hose.

● Do not use adhesive when connecting the supplied drain

hose to the drain port (either on the main unit or the PVC

pipe).

Reasons: 1. It may cause water to leak from the connec-

tion. Since the connection is slippery just

after the adhesive has been applied, the pipe

●Attach the hose bands so that each is approximately 13/64" to 63/64" from the end of the supplied drain hose.

easily slips off.

2. The pipe cannot be removed when mainte-

nance is needed.

● Wrap the hose with the supplied drain hose insulation and

use the 4 twist ties so that the hose is insulated with no

gaps.

● Do not bend the supplied drain hose 90° or more. The hose

may slip off.

NOTE

Make sure the drain pipe has a downward gradient (1/100 or more) and that there are no water traps.

CAUTION

●In cases where it is necessary to raise the height of the drain piping, the drain piping can be raised to a maxi- mum height of 2.78 ft. above the bottom surface of the ceiling. Under no conditions attempt to raise it higher than 2.78 ft. above the bottom surface of the ceiling. Doing so will result in water leakage. (Fig. 3-34)

●Do not use natural drainage.

●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. 3-35)

●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 sup- port as close to the unit as possible. (Fig. 3-36)

●Provide insulation for any pipes that are run indoors.
