2 Note to Installer
This freezer must be installed and
serviced by an Electro Freeze Distributor
or authorized service technician
in accordance with the installation
instructions in this manual.
Verify the weight of the freezer. Ensure
a counter or table of sufcient strength
is used to hold this weight and prevent
excessive vibration.
Air cooled models require a minimum of
3-inches (7.6 cm) air space on both sides
and back of the freezer for adequate
ventilation.
If this freezer is to be used in a self-
service application, it is recommended
that the machine be tted with a self-
service kit. Contact your Electro Freeze
Distributor or H. C. Duke & Son, LLC for
this kit.
Test the operation of the head safety
switch prior to placing the freezer
in service. See Section 12, Routine
Maintenance, Monthly.
After installation the warranty registration
card must be completed and returned to
validate the warranty.

the freezer next to the power supply. A
3/8” MPT water inlet connector will be
needed.
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).
CAUTION
Use caution when moving the

CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electric Code (NEC).
CAUTION
To prevent accidental electrical
shock, a receptacle with
a positive earth ground is
required.
1. Always verify electrical specications
on the data plate (gure 4-1) of
each individual freezer. Data plate
specications will always supersede
the information in this manual.
2. This freezer requires a protected 20
amp 230 volt circuit. Connect the
freezer to a circuit separate from any
other electrical equipment. The power
cord on this freezer connects to a
NEMA 6-20R receptacle. See Figure
3-1.
3. Supply voltage
must be within
±10% of voltage
indicated on
the nameplate.
Request your
local power
company
to correct
any voltage
problem.
4. The control transformer in the
electrical box is factory wired to 208
volts (red) wire tap for 208V nominal
power supply. If power supply is
between 230-240 volts use 240V
(orange) wire tap on transformer.
5. Beater Shaft Rotation - Freezers are
designed for clockwise rotation when
viewed from front of freezer. 1ph
machines are pre-wired for proper
rotation. On 3phase machines,
phase wires to freezer should be
connected to produce proper beater
rotation. This is to be done by a
freezer technician.
