STANDBY Key
The Separate Hopper Refrigeration (SHR) system and
the Cylinder Temperature Retention (CTR) system are
standard features. The SHR system incorporates the use
of a separate small refrigeration system to maintain the
mix in the hopper below 40°F (4.4°C) to ensure bacteria
control. The CTR system works with the SHR system to
maintain a good quality product. If product is not
dispensed for long periods of time, it is necessary to
warm the product in the freezing cylinder to
approximately 35°F to 40°F (1.7°C to 4.4°C) to prevent
overbeating and product breakdown.
To activate the SHR and CTR systems, press the
