Stoelting O111 Extended Storage, Product Consistency Adjustment, Quarterly, Semi-Annually

2.Remove the drip tray by gently lifting up to disengage from the support and pulling out. Clean behind the drip tray and front of the freezer with a soap solution.

D.QUARTERLY

WARNING

High voltage will shock, burn or cause death. Turn off and lock out main power disconnect before ser- vicing. Do not operate machine with panels re- moved.

The air-cooled condenser is a copper tube and aluminum fin type. Condensing is totally dependent upon airflow. A plugged condenser filter, condenser, or restrictions in the louvered panel will restrict airflow. This will lower the capacity of the system and damage the compressor.

The condenser must be kept clean of dirt and grease. The freezer must have a minimum of 3” (7.5 cm) of ventilation on the right and left sides of the unit for free flow of air. Make sure the freezer 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 freezer, inlet and discharge lines must be 3/8” I.D. minimum.

The condenser and condenser filter require periodic clean- ing. To clean, refer to the following procedures.

1.Remove the Phillips head screw from the bottom of the right side panel, and then slide the panels down and out.

2.To remove the condenser filter, grasp the top and pull off. Visually inspect for dirt. If the filter is dirty, shake or brush excess dirt off the filter and wash in warm, soapy water. Once the filter is clean rinse thoroughly in warm, clear water and shake dry, taking care not to damage the filter in any way (Figure 28).

3.Visually inspect the condenser for dirt by shining a light through the coil from the back (inside) of the condenser.

4.If the condenser is dirty, place a wet towel over the front (outside) of the condenser.

5.Using a vacuum, carefully clean the condenser coil from the inside and outside of the freezer. A stiff bristled brush may help in releasing debris from between the condenser coils.

E.SEMI-ANNUALLY

1.Check drive belt for proper tension. Push belt in with one finger, belt should deflect about 3/8".

2.Lubricate condenser fan motor with S.A.E. 20 weight oil. Three to six drops is required.

CAUTION

Do not over-lubricate; resulting damage could cause motor failure.

3.14 EXTENDED STORAGE

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

A.Turn the Main Freezer Power OFF-ON switch to the OFF position.

B.Disconnect (unplug) from the electrical supply source.

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

NOTE

Do not let the cleaning solution stand in the hopper or in the freezer barrel during the shutdown period.

D.Remove, disassemble and clean the front door, mix inlet regulator and auger parts. Place the auger flights and the front auger support bushing in a plastic bag with a moist paper towel to prevent them from becoming brittle.

E.In a water cooled freezer, disconnect water lines and drain water. With a flathead screwdriver, hold the water valve open and use compressed air to clear the lines of any remaining water.

3.15 PRODUCT CONSISTENCY ADJUSTMENT

The IntelliTec control monitors the consistency (firmness) of the product (mix) in the freezing cylinder by monitoring the drive motor amp draw. When consistency is reached, the drive motor and refrigeration system will shut off. The control panel on the front of the freezer allows the operator to adjust the freezing cylinder to create the desired product consistency.

A.Place the FREEZING CYLINDER OFF/ON switch in the ON position.

B.Press the SET button on the Control Panel once. Fine Adj will appear on the LCD screen (Fig. 3- 12).
