Twin Twist Soft Serve Freezer Model GES-103

1 Introduction

The GES-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.

Twin Twist Soft Serve Freezer Model GES-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. 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).

Twin Twist Soft Serve Freezer Model GES-103

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.

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.

IMPORTANT: Unit requires air ventilation. The minimum air space at the sides must be 6 inches (15.2cm) and 1 in.(2.5cm) in the rear or 6 inches in the rear and 1 inch on the sides. Top must have 29 inches clearance. Failure to follow minimum air clearances will void warranty.

3. All models require 6 inches (15.3 cm) minimum air space at rear, 1in(2.54 cm) on sides or 6 inch (15.3 cm) on each side and 1inch (2.54cm) at rear. Space above freezer is to be 29 inch (79.7 cm) and is to be provided with

an 6 in (15.3 cm) air deector at rear

if boxed on 3 sides. Insure freezer is

not subjected to hot exhaust air from other equipment. Anything blocking ventilation, (e.g. cone dispenser), 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

CAUTION To prevent accidental electrical shock, a positive earth ground is required.

1. Always verify electrical specications

on the data plate of each individual

freezer. Data plate specications will

always supersede the information in this manual. (See Figure 3-2)

184560 3

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.

Twin Twist Soft Serve Freezer Model GES-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. 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 right 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. Beater Shaft Rotation Freezers are designed for clockwise rotation when viewed from front of freezer. 1ph machines are prewired for proper rotation. On 3 phase machines, phase wires to freezer should be connected to produce proper beater rotation. This is to be done by a freezer technician.

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.
