Indicator Light – MIX LOW
A mix level indicating light is located on the front of the
machine. When the light is flashing, it indicates that the
mix hopper has a low supply of mix and should be refilled
as soon as possible. Always maintain at least 3 in. (76
mm) of mix in the hopper. If you neglect to add mix, a
freeze-up may occur. This will cause eventual damage to
the beater, blades, drive shaft, and freezer door.
MIX Button
When the MIX button is pressed, the light comes on,
indicating the mix hopper refrigeration system is
operating. The mix refrigeration is controlled by the left
side of the freezer as viewed from the operator end. The
Mix Refrigeration function cannot be canceled unless the
Auto or Standby modes are canceled first.

STANDBY Button
The separate hopper refrigeration (SHR) system and the
cylinder temperature retention (CTR) system are
standard features. The SHR feature incorporates the use
of a separate, small refrigeration system to chill the mix in
the hopper and to maintain the mix's temperature below
40°F (4.4°C). It also ensures bacteria control. The CTR
feature works with the SHR to maintain a good quality
product. During long "no sale" periods, it is necessary to
warm the product in the freezing cylinder to
approximately 35° to 40°F (1.7° to 4.4°C) to prevent
overbeating and product breakdown.
To activate the SHR and CTR features, press the
STANDBY button. Remove the air orifice and place the
air tube (end without the hole) into the mix inlet hole.
When the STANDBY button is pressed, the light comes
on, indicating the CTR system feature has been
activated. In the Standby mode, the Wash and Auto
functions are automatically canceled. The Mix
Refrigeration function is automatically locked in to
maintain the mix in the hopper.
To resume normal operation, press the AUTO button.
When the unit cycles off, the product in the freezing
cylinder will be at serving viscosity. At this time, place the
air tube (end with the hole) into the mix inlet hole and
5-2
install the air orifice.
WASH Button
When the WASH button is pressed, the light comes on.
This indicates beater motor operation. The Standby or
Auto modes must be canceled first to activate the Wash
mode.
Note: The Model 336 cannot be operated in
the WASH mode if the opposite side of the freezer is in
AUTO. Failure to comply with this instruction will cause
the rinse or sanitizing solution to freeze.
AUTO Button
When the AUTO button is pressed, the light comes on.
This indicates that the main refrigeration system has
been activated. In the Auto mode, the Wash or Standby
functions are automatically canceled. The Mix
Refrigeration function is automatically locked in to
maintain the mix in the mix hopper.
Note:
An indicating light and an audible tone will sound
whenever a mode of operation has been pressed. To
cancel any function, press the button again. The light and
mode of operation will shut off.
RESET Button

overload condition. If an overload occurs, the reset
mechanism will trip. To properly reset the freezer:
1. Press the AUTO button to cancel the cycle.
2. Place the power switch in the OFF position.
3. Press the RESET button firmly.
WARNING: DO NOT use metal objects to
