Operator's Safety Precautions 1. 2. 3. 4. 5. 6. Read and understand the operating instructions in this manual thoroughly. Note all warning labels on the freezer. If any warning labels are missing or damaged replace them immediately. Do not wear loose fitting garments or jewelry which could cause a serious accident. Stay alert at all times during operation. Keep operating area clean. Do not operate freezer if any excessive noise or vibration occurs. Contact your authorized service agent.
Installing Your Unit ! CAUTION: Do not alter or deform the plug in any way. Altering or deforming plug may damage unit and will void warranty! Receptacle NEMA 6-20R required for Model 5512. 1. Place freezer in a location that allows adequate space at each side and above for proper air circulation. Minimum clearance is: 6” (15 cm) on both sides, 4” (10 cm) at back, and 8" (20 cm) above the freezer. See figure B.
Installation of Exposed Filter Accessory Kit (optional) (Part #W089.0206) 1. Remove the four panel screws. 2. Pull the bottom of the panel out. 3. Run a bead of the silicone adhesive at the inside back of the bottom filter channel. (2) 4. Install the channel over the end of the side panel so the adhesive in the channel contacts the bottom edge of the side panel. Figure F 5. Put the panel with the channel added, back in place on the machine and reinstall the two lower panel screws. 6.
Operation & Adjustments How to Operate: 1) Sanitize unit following the cleaning instructions on page 12. 2) Fill hopper with product. Allow barrel to fill with product to the proper level, then install carb tube. 3) Turn power switch (toggle switch located underneath the electrical box) to "on" position. 4) Turn mode switch (rocker switch located next to power switch) to “freeze” position. 5) Allow product to freeze in barrel. 6) To dispense product pull down valve handle and release when done.
Overrun Overrun is the increase in product volume, expressed as a percentage, resulting from the entrapment of air in liquid mix as it is frozen. The rotating dasher blends air into the mix as it is frozen resulting in increased frozen product volume. For example, if one gallon (1) (4.4 liters) of liquid mix is poured into a freezer and one and a half gallons (1/2) (6.6 liters) of frozen product is drawn out, the result is a fifty percent volumetric increase, or a fifty (50%) percent “overrun”.
Standby Switch The "STANDBY" switch allows the operator to retain optimum product quality and conserve energy during extended non-draw periods. The Stand-by mode keeps the mix in the hopper at a safe storage temperature and allows the product in the freezing cylinder to return to a refrigerated liquid state. Switching back to "ON" quickly returns the product in the freezing cylinders to proper serving consistency. At the start of the “STANDBY” period: 1. Fill the hoppers with fresh mix. 2.
Product Tips (cont.) Some cappuccino or latte’ mixes contain dairy products which can spoil if not refrigerated. If the freezer is to be turned off at night these products must be removed from the freezer. Contact your local health department regarding their regulations regarding proper mix handling and storage. Consistency Control - Overview ! CAUTION: SHOCK HAZARD! THIS ADJUSTMENT REQUIRES REMOVAL OF THE ELECTRICAL BOX COVER AND SHOULD BE MADE BY A QUALIFIED SERVICE TECHNICIAN.
Consistency Control -Overview (cont.) WASH (D3) - Illuminated when the mode switch is in the wash or "Clean" position. FREEZE (D4) - Illuminated when the mode switch is in the "Freeze" mode. DISPENSE (D5) - Illuminated when the dispensing valve is open calling for both the compressor and drive motor to operate. GREEN CONSISTENCY (D6) - Off when the motor and compressor are off. Illuminated when the compressor and dasher are bringing product to preset consistency.
! CAUTION: THIS CONTROL SETTING IS VERY SENSITIVE SO ALWAYS MAKE SMALL ADJUSTMENTS. IF YOU VISUALIZE THIS CONTROL AS A CLOCK FACE, A ONE HOUR CHANGE WILL MAKE A NOTICEABLE DIFFERENCE IN HOPPER PRODUCT TEMPERATURE. A RECOMMENDED SETTING IS 11:00. Care & 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.
Care & Cleaning (cont.) 3. Using medium sized brush (supplied with freezer) clean the bottom of the valve body and the inside of the plunger bore with detergent solution taking care to remove all remaining lubricant (see figure K). Repeat for other side. Sanitizing Carburetor and Valve Components 1. Re-assemble carburetor assembly installing the two “O” Rings at the bottom of the carb tube. Figure L Sanitize Valve Body 2. Place the carburetor assembly in the bottom of the hopper. 3.
Sanitizing & Refilling (cont.) 5. Use a clean piece of paper toweling to pick up the large end of the carburetor from the bottom of the hopper taking care not to touch the sanitized carburetor with your bare hands. 6. Apply the lubricant on the other piece of paper toweling to the two “O” Rings on the bottom of the carburetor assembly (see figure S). 7. Place the lubricated carburetor assembly on a clean piece of paper toweling. Figure R Lubricate Carb Tube 8.
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 clean water. 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.
Sanitizing and Refilling 1. Prepare a minimum of 3-1/2 gallons (13 liters) of sanitizing solution (Divorsol CX or equivalent) following the manufacturer's instructions. NOTE: Add sanitizer to 3-1/2 gallons of water (warm) to achieve a concentration of 200 parts per million. 2. Pour sanitizing solution into the mix storage hopper and allow the solution to fill freezing cylinder. Use a brush to clean the hopper sides and bottom. (Repeat steps 1 & 2 for opposite side.) 3.
How to Clean Concealed Filter: 1. For concealed filters lift lid and pull up on filter tab to remove 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 filter into top of filter cover with removal clip up and the air flow arrows facing the existing panel. ! CAUTION: Disconnect power for maintenance.
Belt Adjustment ! CAUTION: UNPLUG THE MACHINE BEFORE PERFORMING ANY ADJUSTMENTS. THIS PROCEDURE MUST BE DONE BY A QUALIFIED TECHNICIAN. Figure CC Check the belt tension. The proper belt deflection is 1/2" over all. If the deflection is more than 1/2" the motor will need to be lowered. If the deflection is less than 1/2" the motor will need to be raised. Follow this procedure to adjust the motor to achieve proper belt tension. 1. Unplug the machine and remove both side and the rear panels. 2.
