1 Introduction
This freezer is designed to produce four
avors of milkshakes plus vanilla, 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. Syrups should
be free of pulp, seeds or matter that could
clog injection ports. 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
CS704 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.
This freezer must be installed and serviced by an Electro Freeze Distributor or
authorized service technician in accordance with the installation instructions.
After installation, the warranty registration card must be completed and returned to
validate the warranty.

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.
