FREEZE-UP

If a freeze-up does occur, use the following steps to
thaw the mix in the freezer barrel:
CAUTION
IF THE DRIVE BELT SQUEALS WHEN THE
CLEAN-OFF-SERVE SWITCH IS PLACED IN
THE SERVE POSITION, OR WHEN THE
SPIGOT IS OPENED TO DISPENSE PRODUCT,
TURN THE CLEAN-OFF-SERVE SWITCH TO
THE OFF POSITION.
A. Check to make sure the spigot handle is closed
completely, spigot switch is functioning properly,
there is mix in the hopper, or the mix inlet regulator
(carburetor) is not plugged.
B. If drive motor overload was tripped, remove the
middle front panel and push the reset button. If it
will not reset wait 5 minutes and try again.
C. Place the CLEAN-OFF-SERVE switch in the SERVE
position and push the PUSH TO FREEZE switch.
D. The product will be ready to serve when the green
light illuminates.
E. If the freezer continues to freeze-up, contact a
qualified refrigeration service technician, local
distributor, or Stoelting, Inc.

CONDENSER SERVICE

A. Visually inspect the condenser for dirt by shining a
light through the louvers.
B. If the condenser is dirty, vacuum all loose dirt.
C. If using compressed air or CO-2 tank to blow out
the dirt, first place a wet towel over the front of the
condenser.
D. Blow out the dirt from the back of the condenser.
Most of the dirt will cling to the wet towel.
THIS PROCEDURE EMITS A LOUD NOISE.
E. An alternative method is to clean with a condenser
brush and vacuum.
4.4

EXTENDED STORAGE

Refer to the following steps for winterizing the freezer
for winter lay-up or any extended period of storage.
A. Clean thoroughly with a warm mild detergent all
parts that come in contact with mix. Rinse in clear
water and dry all parts. Do not sanitize as prolonged
exposure of metal parts to some sanitizers can
cause corrosion.
Do not let cleaning solution stand in freezer barrel
or hopper during the shutdown period.
B. Remove, disassemble, and clean the front door,
auger and mix inlet regulator (carburetor). Leave
disassembled during the shutdown period.
C. Place plastic auger flights, rear bearing and front
bearing in a plastic bag with a moist paper towel.
This will prevent parts from becoming brittle if
exposed to dry air over an extended period of time
(over 30 days).
BARREL MUST BE EMPTY FOR FOLLOWING
PROCEDURE.
D. On water cooled freezers, shut off and disconnect
water supply at rear of freezer; run compressor for
2 to 3 minutes to open water valve, and blow out all
water first through inlet, then outlet line, using air or
carbon dioxide.
E. Disconnect the freezer from the electrical supply in
the building.
