1 Introduction
This freezer is designed to produce
milkshakes with a temperature range of
24° to 30°F (-4° to -1°C). If such products
are prepared from powdered concentrate,
they should be precooled to 38°F (3°C)
prior to introduction to the freezer. Use
of other products in this machine is
considered misuse (see Warranty).
This manual has been prepared to assist
you in the proper operation and general
maintenance of the H.C. Duke & Son,
LLC. Model CS700 Freezer.
Your freezer will not compensate for or
correct any assembly or priming errors
made during the initial start-up. Therefore,
it is important to follow the assembly
and priming procedures detailed in this
manual.
Make sure all personnel responsible for
equipment operation completely read and
understand this manual before operating
the freezer. When properly operated and
maintained, the freezer will produce a
consistent quality product.
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.
Freezer is equipped with a deector plate
that will need to be mounted. Facing
the front of the freezer the plate will
be mounted on the screws on the left
side panel. The deector is required to
prevent air from recirculating back to the
freezer. Failure to install deector will void
warranty.
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 switch
prior to placing the freezer in service.
See Section 11, Routine Maintenance,
Monthly.
After installation the warranty registration
card must be completed and returned to
validate the warranty.

other electrical equipment. The power
cord on this freezer connects to a NEMA
6-20R receptacle. See Figure 2-1.
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 transformer in the electrical
box is factory wired for 240 volts. This
connection maybe used for all voltages
above 200 volts. If the power supply
is less than 200 volts, move the L2
transformer wire connector to the 208 volt
connector.

position operates the beater only (no
refrigeration). Always use this mode
when performing cleaning and sanitizing
operations.
b. “OFF” (center) — In this

system will not operate.
Important:
Do not use the “AUTO” position with
water or sanitizer in the cylinder — the

c. “AUTO” (right) — This
position activates both the beater motor
and refrigeration unit. This is the normal
operating position which will maintain a
cylinder temperature of 26° to 28°F (-3° to
-2°C).
The following paragraphs describe the
operator controls and indicators. Refer to
gure 5-1 for location of these controls
