in Fig. 3-5. Use 1 nut and 1 washer for the upper side,

and 2 nuts and 1 washer for the lower side, so that the

3-4. Installing the Drain Piping

(1) Prepare a standard hard PVC pipe (O.D. 1-1/4 in.) for

the drain and use the supplied drain hose and hose

band to prevent water leaks.

The PVC pipe must be purchased separately. The

drainage. (Fig. 3-6)

CAUTION

●Insert the drain pipe until it contacts the socket, as shown in Fig. 3-6, then secure it tightly with the hose band.

●Do not use adhesive when connecting the supplied hose.

Reasons: 1. It may cause water to leak from the connection. Since the connection is slippery just after the adhesive has been applied, the pipe easily slips off.

2.The pipe cannot be removed when maintenance is needed.

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

●Align the hose bands with the end of the hose. Tighten the hose band firmly. Please make sure that the bead is not covered by the hose band. (Fig. 3-6)

CAUTION	Tighten the hose clamps so
	their locking nuts face upward.
	(Fig. 3-6)

(2)After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe. (Fig. 3-7)

NOTE

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