The signal words — DANGER, WARNING and
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.

1 Introduction
The GEN-2080 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 25°F (-9 to -4°C). It also produces
shakes with a product temperature of
26°F (-3°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 Soft
Serve and Shake Freezer Model GEN-
2080.
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.
If you require technical assistance, please

Freeze Distributor as follows:

2 Note to Installer
This freezer must be installed and serviced by an Electro Freeze Distributor or
authorized service technician.
After installation the warranty registration card must be completed and
returned to validate the warranty.

2.1 Uncrating and Inspection
Figure 2-1 Machine Bolted to Shipping Base
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.
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 (gure 2-1) and
install either the legs or casters (gure
2-2).
Figure 2-2 Installing Mounting Legs or Casters
2.2 Installation
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).
1. This freezer is designed for indoor
use and must be protected from outdoor
weather conditions.
– continued
NOTE: Screw casters
or legs all the way in
coupling, then adjust
out to level side to side
with a 1/4” slope to the
front.

2. Where codes permit, we
recommend that the freezer be installed
on casters and have exible water and
electrical connections for service and
cleaning ability.
3. All models require a minimum 6
inch (15 cm) clearance on either the side
panels or the rear panel for adequate
ventilation. Freezers designed with top air
discharge require that at least 18 inches
(45 cm) above the top panel be free of
obstructions. Anything blocking ventilation
of the freezer (including cone dispensers)
will reduce the efciency of the freezer.
4. Water cooled models will require
a 1/2 inch MPT water inlet and water
waste connection. Both condensers are
2.3 Electrical Requirements
2.2 Installation (continued)
3. Refer to the wiring diagram
provided for proper power connections.
4. Electrical connections are made in
the junction box located mid-level behind
the left side panel.
5. Use a exible connection when
permissible. All materials and connections
must conform to local codes and the
National Electrical Code.
6. For 3 phase freezers, beater shaft
rotation must be clockwise as viewed
from the front of the freezer.
2.4 Electrical Connections
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
specications.
tied together so that one water inlet and
one water waste is all that is required.
The connections are found on the bottom
under the compressor mounting area
and are tagged “Water Inlet” and “Water
Waste.” A manual shut-off valve should be
installed in the water inlet line at the time
of installation. The water pressure must
be above 35 psig (241 kPa) and below
140 psig (965 kPa) for proper operation.
5. Place the freezer in the nal
location and level by adjusting the legs or
casters so that it is level side-to-side and
the front is approximately ¼ inch lower
than the rear (to allow proper drainage of
the freezing cylinder).
2. Supply voltage must be within
+ 10% of voltage indicated on the
nameplate. Also, on three-phase
systems, voltage between phases must
be balanced within 2%. (More than a 6
volt difference between any two voltage
measurements at 208-230 volts indicates
a possible imbalance.) Request your 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.
1. Always verify electrical
specications on the data plate of each
freezer. Data plate specications (see
Figure 3-1) will always supersede the
information in this manual.
CAUTION
To prevent acciden-
tal electrical shock, a
positive earth ground is
required.
CAUTION
To prevent accidental elec-
trical shock, a positive earth
ground is required.

Please note that in the following pages of this manual,
some sections relate specifically to either the “Soft
Serve” side of the freezer or the “Shake” side of the
freezer. The GEN-2080 combination freezer actually
contains two separate systems — one side provides
soft serve ice cream and the other, shakes. Although
there are some part and procedure similarities
between the shake and soft serve sides, we have
separated them to make it easier for you to find the
information you need. You may notice a duplication of
some information. Where feasible the information is
only provided once, for both sides.
Look for the Electro Freeze Cone and term “Soft
Serve” in the section header for instructions
concerning the frozen dessert side of the freezer.
Look for the Electro Freeze Shake and the term
“Shake” in the section header for instructions
concerning the shake side of the freezer.
