ELECTRO FREEZE Soft Serve Model GEN-2080

1 Introduction

The GEN-2080 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). It also produces shakes with a product temperature of 26°F (-3°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 and Shake Freezer Model GEN-

2080. 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.

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:

2.1 Uncrating and Inspection

Be sure to properly support the machine when removing bolts and installing legs or casters.

CAUTION

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,

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).

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

Figure 2-2 Installing Mounting Legs or Casters

2.2 Installation

CAUTION All materials and connections must conform to local requirements and be in compliance with the National Electrical Code (NEC).

ELECTRO FREEZE Soft Serve Model GEN-2080

2.2 Installation (continued)

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 (15 cm) clearance on either the side panels or the rear panel for adequate ventilation. Freezers designed with top air discharge require that 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 models will require a 1/2 inch MPT water inlet and water waste connection. Both condensers are

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 freezer. Data plate specications (see

Figure 3-1) will always supersede the information in this manual.

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 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 above 35 psig (241 kPa) and below 140 psig (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 lower than the rear (to allow proper drainage of the freezing cylinder).

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.

2.4 Electrical Connections

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

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.

185240 3

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.

NOTE: Combination Soft Serve/Shake

Freezers

Please note that in the following pages of this manual, some sections relate specifically to either the “Soft Serve” side of the freezer or the “Shake” side of the freezer. The GEN-2080 combination freezer actually contains two separate systems — one side provides soft serve ice cream and the other, shakes. Although there are some part and procedure similarities between the shake and soft serve sides, we have separated them to make it easier for you to find the information you need. You may notice a duplication of some information. Where feasible the information is only provided once, for both sides.

Look for the Electro Freeze Cone and term “Soft Serve” in the section header for instructions concerning the frozen dessert side of the freezer.

Look for the Electro Freeze Shake and the term “Shake” in the section header for instructions concerning the shake side of the freezer.

15 Product Information

15.1 Overrun

As mix is frozen in the freezing cylinder, air is incorporated into the mix to increase its volume, as well as enhance the taste

and texture of the nished product. The

increase in volume is called overrun. Fifty percent overrun means a volume increase of 50% — 10 gallons of liquid

mix has become 15 gallons of nished

product. Controlled overrun is important to

maintaining consistency in product quality. Too much overrun (air) results in a light,

uffy product lacking the cold, refreshing

appeal of a quality product. Too little overrun results in a soggy, heavy product.

To correctly measure the overrun, perform the following steps:

1. Place an empty pint container on the scale* and adjust your scale to zero.

2. Remove the container from the

scale and ll with liquid mix to the top.

Weigh the container and record.

3. Replace liquid mix with frozen product, being sure to leave no voids or air spaces in the container.

4. Strike off the excess product so it is even with the top of the container and measure the weight.

5. Use the following formula to gure

overrun percentage: “Weight of liquid mix minus weight of

frozen product / divided by the frozen weight.” See example:

Weight of one pint of mix = 18 oz. Weight of one = 12 oz.

pint frozen product Difference = 6 oz.

6.0 oz. divided by 12 oz. = .5 .5 x 100 = 50% overrun

* Your Electro Freeze Distributor can provide a scale (P/N 158049) that is graduated in overrun percentage.

58 185240

ELECTRO FREEZE Soft Serve Model GEN-2080

15.2 Overrun Adjustment

NOTE: Each person who operates the freezer should know what overrun is and how to calculate it.

Overrun is regulated by the air meter. The four air meters supplied with the freezer

each have a different size orice. The

smaller the hole and number, the lower the overrun. The larger the hole and number, the higher the overrun. Each half-size change of the air meter number will change the overrun 3-5%; each fullsize change of the air meter number will change the overrun 8-10%.

The orice or hole in this air meter must

be open at all times. It is the only source of air into the freezing cylinder. Check this

daily!

The mix will be a factor in determining

the amount of overrun you will be able to achieve. Some mixes will accept more air than others, thus affecting the size of air meter you can use. Test to see which air meter will give you the best overrun and the best product. Run each air meter for a few hours until you decide.

You may have a slightly higher overrun

when you rst start up the machine.

After the machine has run long enough to dispense at least one full cylinder of product, you will have the overrun that the machine will hold the remainder of the day. Contact your mix supplier for the recommended amount of overrun for each product used.

15.3 Rerun

Rerun is product that has been drawn through the freezer into a container and has melted down to be re-processed. If local health codes permit the use of rerun make sure to follow these procedures:

1. Store rerun mix in a clean,

sanitized container.

2. Store in a cooler with a

temperature below 40ºF (4.4ºC).

3. DO NOT prime the machine with

rerun. Always skim off and discard foam. Then combine the rerun with fresh mix in a ratio of 50/50 and add to the mix container during operation.

4. Once a week run the mix as low

as possible and discard after closing. This will break the rerun cycle and reduce the possibility of high bacteria and coliform counts.

Figure 15-1 Air Meter

NOTE: Rerun product is unable to accept the same amount of air as fresh product. As a result, the quality will be affected and product may appear grainy and icy.

A. Testing the Head Switch

The head switch feature is designed to prevent the beater shaft from being accidentally activated. The beater motors should not operate with the head assembly removed. It is essential that the proper operation of this

switch be veried routinely. Use the

following instructions to test for proper operation:

CAUTION T o avoid electrical shock

or contact with moving parts, make sure the control pad is “OFF” and that the power switch is “OFF”.

1. Remove the dispense head and beater shaft assemblies.

2. Place the power switch “ON”.

NOTE: Do this test for each freezing cylinder.

3. Press the and “BEATER ON”. Look inside the cylinder at the rear drive coupling for rotation. Press the

freeze button and look inside the cylinder at the rear drive coupling for rotation. Turn the “ BEATER OFF”.

Proper Operation

When “BEATER ON” is activated or the freeze button is pushed, the

display should read “HEAD SWITCH” and not allow coupling/beater shaft rotation. The head switch is operating properly. When the head is replaced the system should reset and allow beater rotation. Make sure the control pad is “OFF” and that the power switch is “OFF”. The freezer is ready to be assembled and put in service.

Mechanical Hazard

CAUTION Moving parts. Do not

place hands in the freezing cylinder. Severe personal injury could result.

When “BEATER ON” is activated or the

freeze button is pushed and the rear drive coupling is rotating and the display does not read “HEAD SWITCH”. Freezer has a head switch or software problem. Turn the power switch “OFF”. DO NOT place the freezer in service until the problem has been corrected.

B. Water Condenser

Check the outlet water temperature of water-cooled

condensers at the oor drain. Ideal

water temperatures should be about 95°F (35°C) with a 70°F (21.1°C) water inlet temperature.

C. MTS Cover Switch

The MTS cover switch feature is designed to prevent the MTS gear motor from being accidentally activated. It is essential that the

proper operation of this switch be veried on a

routine basis. Use the following instructions to test for proper operation:

NOTE: Freezer should be cleaned and disassembled for this test.

1. Be sure all switches are in the “OFF” position.

2. Remove the MTS cover to expose the roller assembly.

3. Turn MTS switch to “ON”.

CAUTION Make sure system is depressurized before proceeding.

Error Code Description/Action Probable Cause Remedy

Main P.C. Board Heartbeat L.E.D not blinking/ U.I. Not Energizing

Occurs if there is a power loss to the Main P.C. Board or a possible U.I. Issue

1. Power Loss to Main P.C. Board

2. Main P.C. Board Fuse blown

1. Check control transformer for main 24 VAC power supply to main P.C. Board.

2. Remove fuse and ohm to check for continuity, if none replace fuse. If once fuse is replaced and power is restored, the Main P.C. Board L.E.D. starts blinking however the U.I. Board does not energize then continue with this troubleshooting chart

3. Power Not being supplied to U.I. Board from main P.C. Board

4. Faulty wire connection

If tested to ground relay coil will read 12 VDC to ground and then zero VDC when activated, if tested across relay coil then it will read 0 VDC if sitting idle, and 12 VDC when activated.

3. Remove communication wire from U.I. Board, This cable connects the U.I. Board to Main P.C. Board. Using a meter set to DC voltage and power to the Main P.C. Board on, test voltage across both Black wires. If voltage reads about 5.96 VDC then Main P.C. Board and the communication cable are working properly and the problem lies with the U.I. Board

4. If 5.96 VDC is read on the black wires but the U.I. Board does not light up, the issue might lie with the communication cable, and that it is not making a good connection with the U.I. Board. Check the connector on the U.I. Board for damaged pins; also check the communication cable for loose wires in the cable connector (Contact Electro Freeze Factory Tech Support).

If a Power Failure Occurs unit will log the change of state i.e. switching to night mode on re-start, when the unit is powered back up. The Power Failure error will be displayed on the screen until the SELECT button is pressed acknowledging the Failure. Once the SELECT button is pressed error will reset.

The Head Switch, Spigot Switch, Center Spigot Switch, Mix Low, and Mix Out Errors will all Auto Reset after

the problem has been rectied.
