FOR THE PLUMBER
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. Even though there isn’t one filter that
will cure all water problems, a good filter combined
with a polyphosphate feeder gives about the best
overall performance.
DRAIN
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.
The ice machine sump drain is 3/4" FPT. There
must be a vent at this connection for proper sump
draining.
