FOR THE PLUMBER

FOLLOW ALL LOCAL CODES:

The recommended water supply line is a 3/8-inch
O.D. copper tubing with a minimum operating
pressure of 20 PSIG and a maximum of 80 PSIG.

Connect to cold water supply line with standard
plumbing fittings, with shut off valve installed in an
accessible place between thewater supply and the
cuber. ln some cases a plumber will be required.

Water Limitations:

An ice machine is a food manufacturing plant, it
takes in a raw material, water, and turns it inot a
food product, ice. The purity of the water is very
important in obtaining pure ice and in maximizing
product life. It is generally better to filter the water,
although there is no one filter that will cure all
water problems. A good filter combined with a
polyphosphate feeder gives about the best overall
performance.

Cold, potable water must be supplied to the water
inlet fitting.

CONNECTIONS:

All drains are gravity type and must have a
minimum of 1/4-inch fall per foot on horizontal
runs. The drains to be installed to conform with the
local plumbing code. Install a vertical open vent on
drain line high point to insure good draining. The
ideal drain receptacle is a trapped and vented floor
drain. Recommended bin drain is 5/8 inch O.D.
copper tubing and should be vented and run
separately. Insulation for high humidity areas is
recommended.

Water Cooled models require another inlet
connection to the condenser, and another drain for
the condenser. The drain must be separate from
the bin drain.

Bin Drain: The bin drains from the bottom, and
needs no vent unless there is a long horizontal run.

Terminate drains above the drain receptacle with
the proper air gap per local code.

The ice machine sump drain is 3/4" FPT. There
must be a vent at this connection for proper sump
drainage.
