OPERATION AND ADJUSTMENTS
How to Operate
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.
5. To dispense product pull down valve handle and release when done.
6. If product consistency is not as desired, adjust per the instructions on page 7.
7. Refill mix storage hopper when “mix out” light is ON.
8. Clean the unit regularly following local health codes.
9. Perform maintenance when necessary to increase the life of the unit. See chart in this manual for regular
maintenance schedule.
Mix Low Function
These models will sense when the mix is low in the hopper. On 3341 and 3342 models, a simple float mechanism is
used to sense when mix is low in the hopper. (see Figure G) When the mix level is low, the mix low light located on
the front of the machine will illuminate. NOTE: Do not run the unit under mix low conditions for long periods of time.
This can affect machine performance or damage componentry.
On 3341A and 3352 models, mix low is sensed via the autofill system. When the mix level is low, the mix low light
will illuminate continuously for 2 minutes. After 2 minutes the light will begin to blink off and on for the next 8 minutes.
At the end of the 10-minute time the light will illuminate fully again. After the 10-minute cycle, the mix out safety
function is activated making the unit inoperable. The safety function shuts off the autofill and refrigeration. The unit
can be reset back to the freeze mode by simply adding mix into the hopper.
NOTE: If the mix low safety function has activated disabling the unit, and the product has not been added for an
extended period of time – verify the product is okay for re-use. If it is not, use fresh product to restart the unit. Empty
the unit of old product and follow cleaning and sanitizing procedures (page 8).
Consistency Adjustment
From time to time, it may become necessary to readjust the consistency setting (thickness) to compensate for
variation between different mixes or to switch from one type of product to another. This adjustment is made
as follows:
1. Disconnect electrical power.
WARNING: Do not attempt to readjust the freezer until electrical power has been disconnected.
2. Remove right side panel (facing the freezer).
3. Use the adjustment screw, situated on the front of the drive motor mounting bracket to
change product thickness. Turn the thumbscrew (3 full turns for red spring, 1 turn for
yellow spring) to make a noticeable change in consistency. (see Figure H)
NOTE: Clockwise is for thicker product consistency and counter clockwise is for thinner
product consistency. (see Figure I)
4. Reinstall the side panel, reconnect power.
5. Turn freezer to “ON” and allow it to freeze to desired consistency.
6. Check product. Repeat process until desired consistency is achieved.
NOTE: When making changes to a colder (thicker) setting, recheck
consistency again after the compressor has cycled off. When adjusting
(counter-clockwise) to a thinner consistency, a large portion of product
should be drawn from the dispense valve to reduce the product thickness
below the new set point (adjustment). Then allow the freezer to refreeze
product to the new setting.
