Power Switch
The center position is OFF. The right position is AUTO,
which activates the beater motor and the refrigeration
system. The left position is WASH, which activates the
beater motor only.
Display Light Switch
The display light switch is under the control channel. The
left position is OFF. The right position is ON and activates
the display light.
Viscosity Adjustment
The viscosity (thickness) of the product can be adjusted
by turning the viscosity adjustment screw on the right
side of the machine, under the display light. Turn the
viscosity adjustment screw clockwise for a thicker
product, or counterclockwise for a thinner product. After
making an adjustment, allow the refrigeration system to
cycle two or three times to accurately evaluate the
viscosity.
Indicator Light—ADD MIX
An ADD MIX indicator light is on the front of the machine.
The light flashes to indicate when the mix hopper has a
low supply of product and should be refilled as soon as
possible.
Indicator Light—MIX OUT
A MIX OUT indicator light is on the front of the machine.
When the light is flashing, it indicates that the hopper is
empty and the mix supply needs replenishing. To prevent
damage to the machine, refrigeration discontinues
automatically when the MIX OUT indicator light is
flashing.
Standby Switch—(Toggle Switch)
This switch determines which mode of operation the
freezing cylinder is operating in. The left position places
the machine in the Auto mode. The right position places
the machine in the Standby mode.
Note:
The power switch must be in the AUTO position
for the Standby switch to function.
Reset Mechanism
Should an overload condition occur, the freezer will
automatically shut down. To properly reset the freezer,
place the toggle switch in the OFF position. Wait 2 or 3
minutes, then press the RESET button located in the left
side panel. Place the toggle switch in the WASH position
and observe the freezer's performance. Return the toggle
switch to the AUTO position.
CAUTION! DO NOT
use metal objects to press
the RESET button.
Failure to follow this instruction may
result in electrocution.
