DANGER
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. 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 Note to Installer
1 Introduction

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
contact your local authorized Electro
Freeze Distributor as follows:

The GEN-5400 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). 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 Model GEN-5400.
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.
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.

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
NOTE: Screw casters
or legs all the way in
coupling, then adjust
out to level with 1/4
inch slope to front.

ELECTRO FREEZE Soft Serve Model GEN-5400

2.2 Installation
CAUTION
All materials and
connections must
conform to local
requirements and be
in compliance with the
National Electrical Code.
1. This freezer is designed for indoor
use and must be protected from outdoor
weather conditions.
2. Where codes permit, Electro
Freeze recommends that the freezer be
installed on casters and have exible
water and electrical connections for
easier service and cleaning.
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 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 double models
will require a 1/2 inch MPT water inlet
and water waste connection. Both water
condensers are 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 clearly 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
between 35-140 psig (241-965 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 (6
mm) lower than the rear to allow proper
drainage of the freezing cylinder.
2.3 Electrical Requirements
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.
CAUTION
To prevent accidental
electrical shock, a
positive earth ground is
required.
1. Always verify electrical
specications on the data plate of each
freezer. Data plate specications will
always supersede the information in this
manual.
Important:
On 1ph freezers, the voltage must
be within +10% and -5

ELECTRO FREEZE Soft Serve Model GEN-5400
4 184297
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.
CAUTION
To prevent accidental
electrical shock, a positive
earth ground is required.
