OPERATOR’S SAFETY PRECAUTIONS IMPORTANT: Failure to comply with the following safety precautions may result in severe personal injury or damage to the machine. 1. Read and understand the operating instructions in this manual thoroughly. Only allow properly trained persons to operate this machine. 2. Note all warning labels on the freezer. If any 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.
Remote Freezers (cont.) The autofill system on the 3341A and 3352 models is designed to keep the product hopper full to a predetermined level. This assembly eliminates the necessity of pre-mixing concentrate and water and the possibility of manual mixing errors. The mixed product is automatically fed to a Remote Fill Control which is located in the freezer. The Remote Fill Control then adds pre-mixed product to the freezer mix storage reservoir as required.
Mix Considerations – General Freezing characteristics are affected by the amount of sweeteners and solids in the mix, called BRIX. BRIX can be measured with an instrument called a refractometer. A BRIX reading of between 11 and 14 will provide optimum freezer operation. Mixes with the correct BRIX level will freeze down to a smooth, uniform consistency. Mixes with too high a brix level will take longer to freezer down and will yield a soft, wet, frozen product.
INSTALLATION Shipment Transit The freezer has been operated and tested at the factory. Upon arrival the complete freezer must be thoroughly checked for any damage which may have occurred in transit. NOTE: A Tip (N) Tell warning device is placed on each shipping carton at the factory. If the arrow tip is blue, the carton has been tipped in transit. (see Figure B) THE CARRIER IS RESPONSIBLE FOR ALL DAMAGE IN TRANSIT WHETHER VISIBLE OR CONCEALED.
Installing Your Freezer (cont.) 7.
OPERATION AND ADJUSTMENTS How to Operate Mix Low Float O-Ring Carburetor Mix Low Float 1. Sanitize unit following the cleaning instructions starting on page 10. 2. Fill the mix storage hopper following the instructions on page 10. Allow barrel to fill with product to proper level, then insert carb tube from parts bag in hole toward rear of hopper. See Figure G. 3. Turn power switch to “ON” position. 4. Allow product to freeze in barrel. Compressor will turn off when product reaches pre-set consistency.
CARE AND CLEANING Cleaning and sanitizing frequency must be followed according to state and local health department regulations. NOTE: Each time the freezer is disassembled, all internal components must be thoroughly washed and sanitized using procedures recommended by your local health department. In lieu of local department recommendations, use a three compartment sink; one compartment to wash parts in detergent, one compartment to rinse, and one to sanitize.
Disassembly and Cleaning (cont.) 5. Slide the rotary half of the seal off the dasher shaft. Inspect both seal components carefully for nicks or cracks. Replace seal if defective. NOTE: To prevent leakage, the surfaces of the rotary seal and stationary seal must be smooth with no chips or cracks. NOTE: All units are shipped with a standard ceramic seal (#W0340201) unless otherwise specified. Certain products contain a coconut oil with requires a different sealing material.
Sanitizing and Refilling 1. Re-assemble carburetor assembly by installing the two “O” Rings at the bottom of the carb tube. 2. Place the carburetor assembly in the bottom of the hopper. 3. Install the “O” Rings on valve plunger and lay plunger assembly on a clean piece of paper towel. 4. Prepare a minimum of 2.5 gallons (9.5 liters) of sanitizing solution (Kay-5 Sanitizer/Cleaner or equivalent) following the manufacturer’s instructions. Figure V Sanitize Valve Body NOTE: Add 1 ounce of Kay-5 to 2.
Clean-In-Place Procedure (Daily Cleaning) This equipment has been approved for a Clean-In-Place procedure that does not require complete disassembly on a daily basis. The unit still requires regular complete disassembly for cleaning and sanitizing. To perform the C-I-P procedure follow the instructions below: 1. Empty any product in the machine and turn to OFF. 2. Disassemble the dispensing valve assembly following the instructions in Disassembly and Cleaning. NOTE: Leave the valve block in place.
Sanitizing Procedure 1. Fill the bucket with 4 gal. (15.14 L) of warm water 120ºF – 180ºF (48ºC – 82ºC). 2. Measure 4 oz. (1/4 cup) (118cc) of the liquid detergent and add to the water. 3. Measure 2 oz. (1/8 cup) (60cc) of bleach and add to the water, then stir, mixing evenly. NOTE: 1/2 oz. (15cc) of bleach per gallon (3.8 L) of water yields a solution of approximately 200 ppm Sodium Hypochlorite needed to satisfy NSF sanitizing requirements. 4.
How to Adjust Belt Unplug the machine before performing any adjustments. This procedure must be done by a CAUTION: qualified technician. 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. (see Figure BB) 1. Unplug the machine and remove both side and rear panels. 2.
Preventative Maintenance Procedure (Every 6 to 12 Months) A preventative maintenance visit should be performed every 6 to 12 months depending on the usage and environment where the unit is placed. (Ex. seasonal machines – once before season, year round machines – twice per year). The following procedures should be performed during a preventative maintenance visit. This does not take the place of daily care and cleaning procedures as described by local health codes and the manual.
TROUBLESHOOTING GUIDE Freezer problems can originate from three sources: improper operation, mix problems or mechanical malfunction. Always check first for improper operation and mix problems before calling a service technician. Caution: Always disconnect power before attempting any maintenance procedures. Only a qualified service technician should perform electrical and mechanical adjustments or repairs.
