Then allow the freezer to refreeze product to the new setting. Decrease Thickness (turn counterclockwise) Figure I Crathco® Remote Beverage Freezers Page 7 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. For units with internal autofill, see section on page 11 for instructions on cleaning and sanitizing the autofill system. Drain and Rinse 1. If the freezer is empty, proceed to Disassembly and Cleaning. If there is product in the freezer, turn the front panel switch to “CLEAN”. On models using Remote Fill Control, (3341A and 3352 models), turn internal autofill “OFF” before draining. 2. Open the front dispensing valve and drain all product from the freezer. Close dispensing valve. 3. Remove the carb tube and pour water into the storage hopper. Allow the water to fill the freezing cylinder. NOTE: Use approximately 2 1/2 gallons (10 liters) of cool water per barrel to rinse freezer. 4. Turn the freezer panel switch to “CLEAN” for 5 minutes. 5. Open the dispensing valve and drain the water from the freezer. Close valve. 6. Turn the freezer “OFF”. Disassembly and Cleaning NOTE: For cleaning and sanitizing before initial start-up, remove carb tube, dispense plunger, handle and spring from parts bag first. 1. Disassemble the dispensing valve assembly (figure J). Pull out valve handle retaining pin while supporting the valve plunger from the bottom (figure K). Push up on the valve plunger and remove the stainless handle (figure L). Slide the valve plunger and spring downward to remove (figure M). Figure J Disassemble Figure K Remove Pin Figure L Remove Handle Figure M Remove Dispensing Valve Plunger and Spring 2. Remove knobs and carefully remove the front dispensing valve assembly, leaving the dasher assembly in the cylinder. Remove the plunger and valve body “O” Rings as shown in figure N. 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 paper 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. Carefully inspect the o-rings and replace if necessary. 3. Remove the dasher assembly from inside the freezing cylinder taking care to avoid damaging the rear seal assembly at the back of the freezing cylinder. Disassemble the dasher assembly by removing the stator rod and front and rear stator rod bearings. 4. Remove stationary half of the shaft seal assembly from the back end of the freezer cylinder. This is accomplished by reaching into the cylinder and pulling seal out with your index finger. (see Figure O). Figure N Ring Removal Figure O Installing the stationary portion seal Page 8 Crathco® Remote Beverage Freezers 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. For these products use the coconut oil seal (#W0340210). The stationary half of the standard seal has a white polished surface. The stationary half of the coconut oil seal Figure P Carb Tube has a glossy black surface. 6. Remove carb tube from bottom of hopper and remove o-rings. (see Figure P). 7. Remove drip tray and empty contents. 8. Take all components to the cleaning area. 9. Prepare 1 gallon solution of hot tap water and a good grade of dishwashing detergent. 10. Thoroughly wash all components in a warm, mild detergent solution, including the inside of the freezing cylinder and mix storage hopper. DO NOT WASH COMPONENTS IN A DISHWASHER. 11. Use a medium sized brush to clean the bottom of the valve body and the inside of the plunger bore with detergent solution taking care to remove all remaining lubricant (figure Q). 12. The exterior of the freezer should be cleaned as needed with a cloth towel. Figure Q Clean Valve Body . CAUTION: Coarse rages, abrasive cleaners and excessive force can damage and/or scratch the surfaces of the freezer. Reassembly NOTE: Allow all parts to dry completely before reassembly. 1. Reassemble drip tray and install. 2. Wet the inner rubber lip of the rotary half of the seal and the back end of the dasher shaft with water. Slide rotary half of assembly onto th...
