1 Introduction
Twin Twist Soft Serve Freezer Model GEN-103
The GEN-103 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.
If you require technical assistance, please
contact your local authorized H.C. Duke &
Son, LLC service company:

2 Note to Installer
This freezer must be installed and serviced by a service technician in
accordance with the installation instructions.
After installation the warranty registration card must be completed and
returned to validate warranty.
184583 1
Twin Twist Soft Serve Freezer Model GEN-103
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. 1. Remove the carton from the
pallet, and move the machine as close
as possible to the permanent location.
2. 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 2-1 Machine bolted to Shipping Base
Figure 2-2 Installing Mounting Legs or Casters
NOTE: Screw casters or
legs all the way in coupling,
then adjust out to level side
to side with 1/4 inc (6mm)
slope to the front.

2.2 Installation
Twin Twist Soft Serve Freezer Model GEN-103
CAUTION
All materials and connections
must conform to local
requirements and be in
compliance with the National
Electrical Code (NEC).
1. 1. This freezer is designed for indoor
use and must be protected from
outdoor weather conditions.
2. 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. 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. 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 (241-965kPa) for proper
operation.
5. 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. 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. 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. 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)
184583 3
2. 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. 3. An easily accessible main power
disconnect must be provided for all
poles of the wiring to the freezer.
Twin Twist Soft Serve Freezer Model GEN-103
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. 1. Double freezers with two
compressors require one power
supply for each side of the freezer.
Each side of the freezer operates
independently.
2. 2. Check the data plate for fuse
size, wire ampacity, and electrical
specications. (See Figure 3-2)
3. 3. Refer to the wiring diagram
WARNING
provided for proper power
connections.
4. 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. 5. Use a exible connection when
permissible.
6. 6. Beater Shaft Rotation Freezers
are designed for clockwise rotation
when viewed from front of freezer.
1ph machines are prewired 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.
Warning: When installing the machine,
insert an all pole disconnect, adequately
sized according to freezer nameplate
marking with electrical contact spacing of
3mm minimum. This should be within sight
of the freezer.

Beater Run: ................... This D.O.B. timer used to delay the beater motor after
the refrigeration shuts down. Beater Run Range: 0 to 10
seconds
Demand Run Comp: ...... The D.O.B. timer used to delay the compressor when
product is being drawn. Demand Run Comp. Range: 0 to
12 seconds
Differential/ Hyst: ........... Symbolizes the differential setting. Differential range: 7 to
20°F i.e. if your cut in is at 18°F and your Differential is at

Dual Diff: ........................ The differential used when product is being drawn out of
the center spigot. Dual Differential range: 7 to 20°F
Idle: ................................ When the unit is cycling on temperature and no product is
being dispensed
Idle Run Comp:.............. Delay on break (D.O.B.) timer used for the compressor
when the unit is in idle mode/no product being drawn. Idle
Run Comp. Range: 0 to 20 seconds
Lock outs: ...................... Allows the function of a specic feature/button to be
temporarily disabled to deter un-necessary usage of that
feature.
Main P.C. Board: ............ Main Control board for the unit, housed behind the trim
strip panel. This board has many connectors on it and is
