CAUTION
All materials and
connections must conform
to local requirements and
be in compliance with the
National Electrical Code
(NEC).
1. The freezer is designed for
indoor use and must be protected from
outdoor weather conditions.
2. Where codes permit, Electro
Freeze recommends that the floor
model freezers be installed on casters
and have flexible water and electrical
connections for easier service and
cleaning.
2. All models require a minimum
6-inch clearance on panels with louvers for
adequate ventilation. Anything blocking
ventilation of the freezer (including cone
dispensers) will reduce the efficiency of
the freezer.
CAUTION
To prevent accidental
electrical shock, a positive
earth ground is required.
1. Always verify electrical specifica-
ELECTRO FREEZE Soft Serve Model SL500
3. Water-cooled model SL500
requires a 3/8-inch MPT water inlet and
water waste connection. The connections
are found on the bottom, under the
compressor mounting area. They are
tagged "Water Inlet" and "Water Waste."
A manual shut-off valve should be installed
in the water inlet line at the time of
installation. The water pressure must be
between 35-140 psig (241-965 kPa) for
proper operation.
4. Place the freezer in its final
location and adjust the legs or casters
so that it is level side-to-side and the
front is approximately 1/4-inch lower
than the rear to allow proper drainage
of the freezing cylinder.
2. Supply voltage must be within +
10% of voltage indicated on the
nameplate. Also, on three-phase systems,
voltage between phases must be balanced
within 2%. (More than a 6 volt difference
between any two voltage measurements
at 208-230 volts indicates a possible
imbalance.) Request your local power
company to correct any voltage problem.
3. An easily accessible main power
disconnect must be provided for all
poles of the wiring to the freezer.
