DUKE Model 957R Soft Serve Freezer
2.2 Installation (continued)
tions are found on the back panel 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.
4.
Place the freezer in the 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 approxi-
mately 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 differ-
ence between any two voltage mea-
surements 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.
2.4 Electrical Connections
CAUTION
To prevent accidental electrical
shock, a receptacle with a
positive earth ground is
required.
1.
Double freezers with two compressors
require one power supply for each side
of the freezer. Each side of the freezer
operates independently.
2.
Check the data plate for fuse size,
wire ampacity and electrical specifica-
tions.
3.
Refer to the wiring diagram provided for
proper power connections.
CAUTION
To prevent accidental electrical
shock, a receptacle with 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.
4.
Electrical connections are made in the
junction box(es) located mid-level
behind the back panel.
5.
Use dual element fuses, rated at 25%
over the full load amperage (FLA)
rating of the freezer. Refer to the data
plate on the rear panel. As mentioned
before, all double head machines
should be wired and fused as indi-
vidual units. Use a flexible connection
when permissible. All materials and
connections must conform to local
codes and/or the National Electrical
Code.
