1 Introduction

Soft Serve Model GEN-101

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.

If you require technical assistance, please contact your local authorized H.C. Duke & Son, LLC service company:

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,

REMOVE HEX HEAD BOLTS (4) AND FLAT WASHERS

Figure 2-1 Machine Bolted to Shipping Base

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).

2.2 Installation

Soft Serve Model GEN-101

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, 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 efciency 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 (241-965kPa) 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

1. Supply voltage must be within + 10%

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.

185239 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.

2. An easily accessible main power disconnect must be provided for all poles of the wiring to the freezer.

Soft Serve Model GEN-101

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

specications. (See Figure 3-2)

3. Refer to the wiring diagram provided

for proper power connections.

4. Electrical connections are made in

the junction boxes located mid-level behind the left side panel.

WARNING

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.

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.

Night Mode Operation

As pictured below, the Soft Key located below the image of the Moon will allow the machine to be switched into NIGHT refrigeration mode. This feature is used at the closing of the day’s business to hold the product at safe storage temperatures but not in a frozen state.

PLEASE NOTE: Dairy Queen allows the Night mode to be used for 72 Hours before the machine MUST be disassembled and cleaned per instructions in this manual.

During the use of the NIGHT mode, the computer will monitor the system and maintain a mix holding temperature of 36°F (2.2°C) or below. The beater will cycle throughout this mode to maintain product circulation through the dispensing head.
