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 the water supply and
the cuber. In 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 into 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
3 ⁄
4
" rigid tubing
and should be routed separately. Insulation for
high humidity areas is recommended.
Water Cooled models require another inlet
connection 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 fitting is 3/4" FPT.
There must be a vent at this connection for proper
sump drainage. Recommended drain tube is
3 ⁄
4
"
rigid tubing and should be routed separately.
Insulation for high humidity areas is
recommended.
