WARNING LABELS OPERATOR'S SAFETY PRECAUTIONS 1) Read and understand the operating instructions in this manual thoroughly. 2) Note all warning labels on the freezer. If any of the warning labels are missing or damaged replace them immediately. 3) Do not wear loose fitting garments or jewelry which could cause a serious accident. 4) Stay alert at all times during operation. 5) Keep operating area clean. 6) Do not operate freezer if any excessive noise or vibration occurs.
Removal from Carton and Pallet 1) Remove staples or cut cardboard box around the stapled area. 2) Pull the cardboard box up off machine. 3) Remove the Styrofoam packing and the plastic bag. 4) Remove both side panels with screwdriver. 5) Use a wratchet with a 3 inch extension and a 7/16 socket to remove the shipping bolts (connecting the machine to the pallet) located on both sides of the frame bottom plate. 6) Supporting all four sides, lift machine up and place in appropriate area.
Installation of Concealed Air Filter Accessory Kit (optional) (Part #s W089.0200 Stainless Steel, W089.0208 Black) 1) Remove the four screws that hold the right side panel on the machine. 2) Install the filter panel over the existing side panel and reinstall screws. (See Figure D) 3) Open top cover of filter cover by raising and rotating away from the existing panel. 4) Slide filter into top of filter cover with removal clip up and the air flow arrows facing the existing panel.
Installation of Spinner/Mixer Accessory Kit (optional) (Part #W089.0053-115V) (Part # W0890124-220V) 1) Turn to "off" and unplug the freezer from the electrical power source. 2) Remove the white plastic plugs covering the threaded holes on the right front panel (facing the freezer). 3) Remove the electrical box cover. 4) Feed the spinner electrical wires through the 7/8” hole in the spinner mounting bracket.
Carburetor Assembly Your new freezer uses a metering device, known as a carburetor, to feed the proper ratio of mix and air into the freezing cylinder. For products such as dairy based shake mixes, the proper mix to air ratio is generally accepted to be two parts mix to one part air. This proportion yields a finished product that is both tasty and profitable. At this ratio, one gallon of liquid mix will yield a volume of one and one-half gallons of frozen product.
Computing Overrun (cont.) 3) Draw a heaping cup of frozen product that contains no air pockets. Note: Use a spatula or other device to help fill the cup completely. Avoid tamping the cup as this artificially reduces overrun. 4) Use a straight edge to scrape off excess product flush with the rim of the cup and weigh the cup. 5) Subtract the cup weight and use the overrun formula to determine overrun.
Mix Low Function (cont.) buzzer is out of the circuit and the light will illuminate fully again. After the 10-minute cycle the mix out safety function is activated making the unit inoperable. The machine is placed into the standby mode to prevent any damage to the machine from running dry of product. The unit can be reset back to the freeze mode by simply adding mix into the hopper. 1.
Product Consistency Adjustment (cont.) 4) When making adjustments to a thicker (colder) setting, dispense approximately 16 ounces (1/2 liter) of product and recheck consistency after the compressor has cycled off. 5) If the consistency is still not correct, repeat steps 2 and 3. "Standby" - Freezing Cylinder Temperature Adjustment 1) Remove the front electrical box cover. (See Figure C).
Consistency Control - Overview (cont.) In the “standby” mode the control board senses the temperature of the product in the barrel. The drive motor is cycled on time only. It will operate for 2 minutes ON then 18 minutes OFF as long as it is in “standby”. The compressor and drive motor are cycled independently for the barrel in the “standby” mode. Once the barrel thermister signals to the board, the board will start the compressor and the barrel solenoid valve will open as refrigeration is required.
CARE AND CLEANING Note: Each time the freezer is disassembled, all internal freezer components must be thoroughly washed, scoured and sanitized using procedures recommended by your local health department. In lieu of local health department recommendations, use a three compartment sink; one compartment to wash parts in detergent, one compartment to rinse, and one to sanitize. Drain and Rinse 1. If the freezer is empty, proceed to Cleaning Following Complete Disassembly of Unit or Daily Cleaning Procedure.
Daily Cleaning Procedure (cont.) Note: The best way to remove an “O” Ring is to first wipe off all of the lubricant using a clean paper towel. Pinch the “O” Ring upward with a dry towel between your index finger and thumb. When a loop is formed in the “O” Ring, roll it out of the groove with your other thumb. Always remove the “O” Ring farthest from the end of the plunger first. (See figure M). 2. Take all components to the cleaning area. 3. Carefully inspect the “O” Rings and replace if necessary.
Sanitizing Carburetor and Valve Components (cont.) 8. Slide the valve plunger spring over the small end of the valve plunger and, using another clean piece of paper toweling, pick up the valve plunger at the outlet end and insert plunger and spring into the valve body (figure Q). 9. Push up on the valve plunger and insert the stainless steel handle (figure R). Figure Q Installing Plunger and Spring 10. Insert the dispensing valve handle retaining pin (figure S) Sanitizing and Refilling 1.
Sanitizing and Refilling (cont.) 11. Watch the product flowing out of the dispensing valve and close the Valve when the sanitizer remaining in the cylinder has been purged by the new mix. 12. Use a clean piece of paper toweling to insert the sanitized carburetor assembly into the inlet hole in the hopper (figure V). 13. Fill mix storage hopper with fresh product. 14. Turn front panel switch to “ON”. Allow approximately 20 to 30 minutes for the freezer to reach proper consistency.
Cleaning Following Complete Disassembly of Unit (cont.) IMPORTANT: After disassembly, thoroughly scour each part of the freezer in a warm mild detergent solution including the inside of the freezing cylinder and the mix storage hopper. Rinse each part with cleanwater. Prepare a minimum of 3 1/2 gallons (13 liters) of sanitizing solution (Divorsol CX or equivalent) following the manufacturer's instructions. Note: Add 3 ounces (85.
Reassembly (cont.) 5. Disassemble the carburetor assembly and remove the O-Rings. Wash and sanitize all parts. 6. Reinstall and lubricate the O-Rings and slip on the outer tube if equipped. (See Figure EE.) Figure EE Thick product carb tube Standard carb tube Sanitizing and Refilling 1. Low overrun carb tube Prepare a minimum of 3 1/2 gallons (13 liters) of sanitizing solution (Diversol CX or equivalent) following the manufacturer's instructions.
How to Clean Exposed Filter: 1. Slide exposed filter out of the rails by pulling forward on the filter. It is recommended to remove the filter by using the palm of your hand and applying even pressure to the face of the filter. 2. Clean filter with liquid soap and water. 3. Soak filter for 15 minutes. 4. Rinse filter with heavy stream of water, opposite the direction of air flow. Allow filter to dry. 5. Slide the filter into the rails until the filter contacts the stop on the top rail.
Annual Maintenance (cont.) 4. Remove dasher assembly, inspect stator bearings and replace shaft seal set. (See Care and Cleaning). 5. Remove rear panel and inspect "V" belt. 6. Inspect the drive shaft square hole for wear (rounding-out). 7. Check drive shaft and motor shaft bearings for excessive wear. 8. Reinstall side and back panels. 9. Re-connect power supply. Belt Adjustment ! CAUTION: Unplug the machine before performing any adjustments.
