FOR THE PLUMBER

CONFORM TO ALL APPLICABLE CODES

Water Inlet

Connect a cold potable water supply

to the ice machine. Use 3/8" O.D.

copper tubing and connect it to the

3/8" male flare at the back of the

cabinet.
Install a hand valve near the machine

to control the water supply.

Drains

The cabinet has a ¾" FPT drain.

connection. The drain is at the back of

the cabinet, the drain line is of the

gravity type, and 1/4 inch per foot fall

is an acceptable pitch for the drain

tubing. There should be a vent at the

highest point of the drain line, and the

ideal drain receptacle would be a

trapped and vented floor drain. Use

only ¾" rigid tubing.

Storage Bin:

Install a

separate

gravity drain to the ice storage bin.

Insulation of this drain line is

recommended.
