MIX REF

When the MIX REF key is pressed, the light comeson
indicating the mix hopper refrigeration system is

STANDBY Key

The Separate Hopper Refrigeration System (SHR)
and the Cylinder Temperature Retention System
(CTR) are standard features on Softec htmachines.
The SHR incorporates the use of a separate small
refrigeration system. This maintains the mix in the
hopper below 40_(4.4_C) to assure bacteria control.
The CTR 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_Fto40_F(1.7_Cto4.4_C) t o
prevent overbeating and product breakdown.
To activate the SHR and CTR, press the STANDBY
key. Place the end of the air tube without the hole into
the mix inlet hole.
When the STANDBY key is pressed, the light comes
on, indicating the CTR (Cylinder Temperature
Retention System) has been activated. In the
STANDBY mode, the WASH and AUTO functions are
automatically cancelled. The MIX REF funct ion is
automatically locked in to maintain the mix in the
hopper.
To resume normal operation, press the AUTO key.
When the unit cycles off, the product in the freezing
cylinder will be at serving viscosity. At this time, place
the orifice end of the air tube into the mix inlet hole.
Install the air orifice.

The light and mode of operation will shut off.

Indicator Light - MIX LOW

Located on the front of the machine is a mix level
indicating light. 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” (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.
