1 Introduction
Soft Serve Freezer Model GEN-102
The GEN Series Freezer is designed
to produce DQ frozen soft serve ice
cream or DQ yogurt, with a product
serving temperature of 18 to 19ºF (-8
to -7ºC). If such products are prepared
from powdered concentrate, they should
be precooled to 40°F (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
in the training of personnel on the proper
operation and general maintenance of
your Duke freezer.
Your freezer will not compensate for
or correct any assembly or priming
errors made during the initial start-up.
Therefore it is extremely important
to follow the assembly and priming
procedures detailed in this manual.
Be sure all personnel responsible for
equipment operation completely read
and understand this manual before
operating the freezer. When properly
operated and maintained, your freezer
will produce a consistent quality product.

Soft Serve Freezer Model GEN-102
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
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).

2.2 Installation
Soft Serve Freezer Model GEN-102
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.
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
(15cm) clearance on either the side
panels and 0 inch in the rear or 6 inch
(15cm) in the rear and 0 inch on the
side panels for adequate ventilation.
Freezers require a least 24 inches
(61cm) clearance above the top panel
and be free of obstructions. Anything
blocking ventilation of the freezer
(including cone dispensers) will
reduce the efciency of the freezer.
4. Water cooled double models will
require a 1/2” 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 (241965kPa) for proper operation.
5. Place the freezer in the nal location
and level the machine by adjusting
the legs or casters so that the unit
is level side-to-side, and the front
is approximately ¼” lower than the
rear, to allow proper drainage of the
freezing cylinder.
6. Water Cooled Do not allow
freezer to be in ambient where
air temperature goes below 0°C
(32°F),the freezing temperature of
water.
7. Water consumption increases
if temperature of entering water is
above 20°C (65°F)
2.3 Electrical Requirements
CAUTION
To prevent accidental electrical
shock, a positive earth ground
is required.
1. Always verify electrical specications
on the data plate of each individual
freezer. Data plate specications will
always supersede the information in
this manual. (See Figure 3-2)
2. Supply voltage must be within + 10%
185232 3
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.
Soft Serve Freezer Model GEN-102
2.4 Electrical Connections
CAUTION
To prevent accidental electrical
shock, a positive earth ground
is required.
Important!
A positive earth ground is required for
electronic VQM system
to operate correctly.
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
specications. (See Figure 3-2)
4. Electrical connections are made in
the junction boxes located mid-level
behind the left side panel.
Important
Set switch next to the connection
box “UP” for 220-230v or “DOWN”
for 208-219V. Failure to set switch to
proper voltage will cause damage to
the electrical components and will void
all warranties.
5. Use a exible connection when
permissible.
6. For 3 phase freezers, beater shaft
rotation must be clockwise as viewed
from the front of the freezer.
3. Refer to the wiring diagram provided
for proper power connections.
