3.11 MIX INFORMATION

Mix can vary considerably from one manufacturer to another. Differences in the amount of butterfat content and quantity and quality of other ingredients have a direct bearing on the fi nished frozen product. A change in machine performance that cannot be explained by a technical problem may be related to the mix.

Proper product serving temperature varies from one manufacturer’s mix to another. Mixes should provide a satisfactory product in the 20°F to 24°F range. Diet and low-carb mixes typically freeze to proper consistency at higher temperatures.

When checking the temperature, stir the thermometer in the frozen product to get an accurate reading.

Old mix, or mix that has been stored at too high a temperature, can result in a fi nished product that is unsatisfactory.

To retard bacteria growth in dairy based mixes, the best storage temperature range is between 33° to 38°F (0.5° to 3.3° C).

To check belt tension, refer to Figure 4-1 and follow the steps below:

Hazardous voltage

WARNING

Make sure the machine is off when disassembling for servicing. The machine must be disconnected from electrical supply before removing any access panel. Failure to disconnect power before servicing could result in death or serious injury.

4.2 CONDENSER CLEANING (AIR-COOLED

MACHINES)

The machine has an air-cooled or water-cooled condenser.

The air-cooled condenser is a copper tube and aluminum fi n type. Condensing is totally dependent upon airfl ow. A plugged condenser, or restrictions in the louvered panel will restrict airfl ow. This will lower the capacity of the system and damage the compressor. The condenser must be kept clean of dirt and grease. The machine must have a minimum of 3” (7.6 cm) of ventilation on the sides of the unit for free fl ow of air. Make sure the machine is not pulling over 100° F (37° C) air from other equipment in the area.

The water-cooled condenser is a tube and shell type. The condenser needs a cool, clean supply of water to properly cool the machine, inlet and discharge lines must be 3/8”

I.D. minimum.

The air-cooled condenser requires periodic cleaning. To clean, refer to the following procedures.

A.

B.

C.

D.

Remove the back panel.

Use a Burroughs Belt Tension Gauge to set the tension for the drive belt. Set the belt tension to

35-40 lbs.

If an adjustment is necessary, loosen the four motor plate retaining nuts, adjust belt tension then retighten the four nuts.

Using a straightedge, check that the drive motor pulley is aligned with the speed reducer pulley.

Align the pulley if necessary.

NOTE

Belt life will be increased if new drive belts are tightened after two or three weeks of operation.

A.

B.

C.

D.

Visually inspect the condenser for dirt.

If the condenser is dirty, place a wet towel over the condenser.

Using compressed air or CO

2

tank, blow out the dirt from the back of the condenser. Most of the dirt will cling to the wet towel.

An alternative method is to clean with a condenser brush and vacuum.

NOTE

If the condenser is not kept clean, refrigeration effi ciency will be lost.

It is recommended that a preventative maintenance schedule be followed to keep the machine clean and operating properly. The following steps are suggested as a preventative maintenance guide.

The United States department of agriculture and the food and drug administration require that lubricants used in food zones be certifi ed for this use. Use lubricants only in accordance with the manufacturer’s instructions.

Figure 4-1 Belt Tension Adjustment

Owner’s Manual #513674 13

Check for any unusual noise or condition and repair immediately.

Check the condenser for dirt and clean if necessary.

Check drive belts for wear and tighten belts if necessary.

F131I2 Model Machines

Refer to the following steps for storage of the machine over any long period of shutdown time:

A. Clean all the parts that come in contact with mix thoroughly with a warm detergent water. Rinse in clear water and dry all parts. Do not sanitize.

B.

NOTE

Do not let cleaning solution stand in the freezing cylinder or hopper during the shutdown period.

Remove, disassemble, and clean the front door, and auger shaft. Leave disassembled during the shutdown period.

C.

D.

E.

F.

Place the auger fl ights and auger support bushing in a plastic bag with a moist paper towel. This will prevent them from becoming brittle if exposed to dry air over an extended period of time (over 30 days).

For water-cooled machines that are left in unheated buildings, or buildings subject to freezing, the water must be shut off and disconnected. Disconnect the water inlet fi tting. The fi tting is located at the rear of the machine. Run the compressor for 2 - 3 minutes to open water valve (the front door must be attached for the compressor to run). Blow out all water through water inlet. Drain the water supply line coming to the machine. Disconnect the water outlet fi tting.

Press the Main Power On/Off button to turn the machine off.

Disconnect the machine from the source of electrical supply.

TROUBLESHOOTING

5.1 ERROR CODES

When the machine experiences a problem, one of the following error codes will be displayed on the control panel. Each error code directs you to the system location of the malfunction.

ERROR CODE MALFUNCTION

Torque

Time

Clean

5 Freezing Cylinder Sensor

Error Code 3 - Run Time

The Run Time Error (E3) occurs when the compressor runs continuously for an extended period. This error is generally caused by very low mix levels in the hopper or from product breakdown. Another common cause results from a restriction preventing mix from entering the freezing cylinder. Check the mix in the hopper.

If the level mix is low, add mix. If there is a possibility that the mix has broken down, clean and sanitize the machine and replace the mix with fresh product.

Hopper Sensor (single hopper machines)

Drive Motor

Cab Sensor

High Pressure Cutout

Prime (cab units only)

Ice crystals in the hopper can clog the mix inlet system and prevent mix from entering the freezing cylinder. Thoroughly thaw mix per manufacturer’s recommendations. To check for ice crystals, pour a small amount of product from the mix container through a clean and sanitized sieve or strainer.

If ice crystals are in the mix, check temperature of the walk-in cooler where the mix is stored.

13

Left Hopper Sensor

Right Hopper Sensor

To return the machine to normal operation, any error causing condition must be corrected and the power to the affected freezing cylinder must be cycled. Turn the power to the freezing cylinder off then back on using the

On/Off button of the affected freezing cylinder.

5.2 TROUBLESHOOTING

In air cooled machines, the Run Time Error may indicate that airfl ow within the machine has reduced or stopped. Check the sides of the machine for anything that would restrict airfl ow.

If the error persists after attempting to clear it, contact your Authorized Stoelting Distributor for further assistance.

Error Code 2 - High Torque

If the control panel displays a High Torque Error

(E2), the controller has sensed that the drive motor is running at a high load for 10 or more seconds.

This may be due to the product consistency adjustment being set too high. Press the On/Off button for the cylinder to turn it off, wait until the product in the freezing cylinder thaws and then turn the cylinder back on. If the error persists, contact your Authorized Stoelting Distributor for further assistance.

Error Code 4 - Clean

If the machine is left in the Clean Mode for more than 20 minutes, the control panel will display a

Clean Error (E4). This condition does not refl ect a problem with the machine itself. The Clean Error has been programmed into the controller as a safeguard to protect the machine from potential damage caused by the machine being accidentally left in "Clean Mode". To clear the Clean Error, press the On/Off button for the cylinder to turn if off then back on.

Owner’s Manual #513674 15 F131I2 Model Machines

The Left Hopper Sensor Error (E12) indicates a failure of the hopper sensor or if the sensor is out of range. If the control panel displays an E12, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting Distributor for further assistance.

Error Code 13 - Right Hopper Sensor

The Right Hopper Sensor Error (E13) indicates a failure of the hopper sensor or if the sensor is out of range. If the control panel displays an E12, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting Distributor for further assistance.

If the control panel displays a Drive Motor Error

(E7), the control does not sense current coming from the drive motor. Press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting

Distributor for further assistance.

Error Code 8 - Cab Sensor

A Cab Sensor Error (E8) will not occur on the machine.

Error Code 9 - High Pressure Cutout

High Pressure Cutout Errors (E9) are usually caused by a dirty or ineffi cient condenser. If the control panel displays an E9 on an air cooled machine, check for proper air clearance around the machine. If there is an E9 on a water cooled machine check for proper fl ow from the water supply or kinks in the hoses.

Error Code 21 - Spigot Open Time

The Spigot Open Time Error (E21) indicates a failure of the spigot switch. If the control senses the spigot is open continuously for 10 minutes, the machine will go into Sleep 3 mode. If the control panel displays an E21, press the On/Off button for the cylinder to turn if off then back on. If the error persists, contact your Authorized Stoelting
