Remote Beverage Freezers
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).
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).
