Consistency Control System
Adjustments to the consistency control should
only be made by a serviceman trained on SaniServ
equipment . DO NOT attempt to make repairs on the
machine
.
The mechanical control system is a very simple method
of controlling the consistency of the finished product.
The machine operates without a temperature control.
Refrigeration is controlled by measuring the torque on
the dasher motor and the consistency of the product.
The tension of a spring against the torque idler
determines how long the unit will run by activating a
limit switch which turns the compressor on and off. The
longer the compressor runs, the harder the product.
The less it runs, the softer the product. This directly
relates to product temperature.
Initial adjustments have been performed at the factory.
However, to satisfy individual preferences, the following
adjustments may be required:
1. Remove the right side panel as viewed from the
front of the machine.
2. Using a regular straight screwdriver, turn the
mechanical consistency or torque adjustment screw
(Fig. 28) clockwise to make the product harder and
counterclockwise to make the product softer. Do not
adjust more than two turns each time.
Do not
attempt
to adjust the belt idler screw on the left side of the
machine marked
“Do Not Adjust”.
EXTREME CARE SHOULD BE EXERCISED TO
KEEP HANDS AND TOOLS AWAY FROM MOVING
PARTS. PERSONAL INJURY COULD RESULT.
3. Replace panels, restore power, wait until the
compressor cycles off, then check the consistency of
the product.
4. Repeat steps 2 and 3 until the desired product
consistency is obtained.
Consistency Adjustment
CAUTION: The following procedure should ONLY be performed by a trained Technician.
NOTE: If product does not freeze to a hard enough
consistency, the problem may not be in the machine.
To verify, use a standard thermometer to obtain the
temperature of the product. The problem is NOT in the
machine if the temperature is between 17
°
and 22
°
F.
Check to see that the product mix was prepared to the
manufacturer’s recommendation.
WARNING
5. Install the right side panel, and the machine is ready
for continuous operation.

WARNING
USE EXTREME CAUTION. ELECTRICAL SHOCK HAZARD EXISTS
EVEN WHEN THE UNIT IS IN THE “OFF” POSITION. DISCONNECT
THE MACHINE FROM ALL OF ITS POWER SOURCES BEFORE
PERFORMING ADJUSTMENTS ON THE MACHINE. PERSONAL
INJURY OR DAMAGE TO THE MACHINE COULD RESULT IF THIS
PRECAUTION IS NOT OBSERVED. ALL PANELS SHOULD BE
REPLACED AND ALL POWER SOURCES SHOULD BE RESTORED
BETWEEN EACH CONSISTENCY ADJUSTMENT.
