SAFETY FIRST!

Follow these four steps to safety ....

1. Recognize Safety Information ....Look for this

safety alert symbol throughout this manual.

When you see this symbol on your freezer or in this
manual, be alert to the potential for personal injury. Follow
recommended precautions and safe operating practices.

2. Understand Signal Words ....

The signal words — DANGER, WARNING and CAUTION —

DANGER

WARNING

CAUTION

are used with the safety alert symbol (DANGER decals on
the freezer may or may not have the safety alert symbol, but
the message is the same). Decals with the words DANGER,
WARNING or CAUTION appear on the freezer. DANGER

identies the most serious hazard. Decals with the words
DANGER or WARNING are typically near specic hazards

on the freezer. General precautions are listed on CAUTION
safety decals.

In this manual, CAUTION messages with the safety
alert symbol

call attention to safety messages.

3. Follow Safety Instructions ....

Read and understand the decal safety messages on your
freezer. Take notice of the location of all decals on the
freezer and keep the safety decals in good condition. Check
them periodically and replace missing, damaged or illegible
safety decals. The safety decals must remain in place and
legible for the life of the freezer. If you need new decals, use
the information and illustrations on pages iv and v of this
manual to identify the decal and order replacement parts.

DO NOT attempt to operate the CS705-M2 freezer until you

1 Introduction

ELECTRO FREEZE Shake Model CS705-M2

The CS705-M2 Freezer is designed to
produce soft serve ice cream, ice milk,
yogurt, and similar frozen dairy products,
with a product serving temperature
range of 15° to 25ºF (-9° to -4°C). If such
products are prepared from powdered
concentrate, they should be precooled
to 40ºF (4°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 Electro Freeze Model
CS705-M2 freezer.

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.

If you require technical assistance, please

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 self­service 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.

2.1 Uncrating and Inspection

CAUTION
Be sure to properly support
the machine when removing
bolts and installing legs or
casters.

When the unit is received and while
the carrier is still present, inspect the
shipping carton for any damage that
may have occurred in transit. If the
SHOCKWATCH® label indicates red and/
or the carton is broken, torn, or punctured
note the damage on the carrier’s freight
bill and notify the carrier’s local agent
immediately. Also note on the freight bill.

2.2 Installation

CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).

CAUTION
Tip Hazard. Front side of
freezer must remain positioned
on door side of cart. DO NOT
reverse position of freezer on
cart.

1. Remove the carton from the pallet,
and move the machine as close as
possible to the permanent location.

2. Remove the shipping bolts on the
bottom of the freezer and remove the
freezer from the pallet.

CAUTION
Use caution when moving the
freezer to avoid a tip hazard.

3. A minimum 3-inch (7.6 cm) air space
is required on both sides and back of
the freezer for adequate ventilation.

4. Test the operation of the head and

ex shaft cover safety switches prior

to placing the freezer in service. See
Section 12, Routine Maintenance,
Monthly.

1. This freezer is designed for indoor use
and must be protected from outdoor
weather conditions.

2. This freezer requires a potable water
connection for the rinse line. The
water inlet is located at the back of
the freezer next to the power supply. A
3/8” MPT water inlet connector will be
needed.

184592-012

ELECTRO FREEZE Shake Model CS705-M2

2.3 Electrical Requirements

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

Figure 2-1

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.

priming and calibrating the avor syrups.

With the syrup switch in the “ON” position,
the selector switch (5) in “AUTO” and

a avor selection (8) made, pressing

this button will activate the pump for

that avor to ush and prime the avor

delivery line and to allow calibration of the

syrup ow.

5.3 Reset - Circuit Breaker Spinner Motor (3)

This control protects the spinner motor
against failure from an overload condition
by automatically shutting it down. To
restart wait 2-3 minutes, then depress the
reset button.

If the circuit breaker trips frequently,
your spinner mechanism and circuitry
should be checked. Contact your
Electro Freeze Distributor.

5.4 Syrup Pump Fuse (4)

This holds the AGC fuse for the syrup &
malt pumps.

5.5 Reset — Circuit Breaker Beater Motor (5)

This control protects the beater motor
against failure from an overload condition
by automatically shutting down the

SELECTOR switch (5) to “OFF”, wait 2-3
minutes, then depress the reset button
and turn the SELECTOR switch back to
the “AUTO” or “CLEAN” position.

Important:
If the circuit breaker trips frequently,
your freezer should be checked for
