2.2 Installation
1. Where codes permit, we recommend
that you install the freezer on casters
and have flexible water and electri-
cal connections for service and
cleaning ability.
2. A minimum clearance of 6-inches is
required on the rear and side panels
for adequate ventilation.
3.
Water cooled
models require a 3/8-
inch female flare water inlet and
water waste connection. The con-
nections are found on the back of
the freezer and are clearly 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 pres-
sure must be between 35-140 psig
(241-965 kPa) for proper operation.
4. Place the freezer in its final location
and level the machine by adjusting
the legs or casters so that the unit is
level side-to-side, and the front is
approximately 1/4" lower than the
rear. This will allow proper drainage
of the freezing cylinder.
2.3 Electrical Requirements
2. Supply voltage must be 10%
of voltage indicated on 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 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.
CAUTION
To prevent accidental electrical
shock, a positive earth ground
is required.
1. Always verify electrical specifications
on the data plate of each individual
freezer. Data plate specifications will
always supersede the information in
this manual.
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).
