e following is a brief guide as to how the FREEZING CYLINDERS operate while
your machine is in STANDBY MODE.
1. When the machine is placed into STANDBY MODE, the compressor and drive
motor will power on.
2. e solenoid valves to the freezing cylinders will open and begin to freeze for 15
seconds and then close for 7 minutes repeatedly.
This cycle continues the entire time the machine is in “STANDBY”, and the tempera-
ture in the hoppers is below 20ºC.
This cycle continues the entire time the machine is in “STANDBY”.
3. e solenoid valves to the hoppers will open and close depending on the tem-
perature of the mix inside the hoppers. When the temperature in the hoppers is
above 20C, the solenoid valve will remain open in order to continue cooling the
hoppers.
4. Once the temperature inside the hoppers has dropped below 20C, the solenoid
valve will begin cycling, open for 30 seconds and closed for 7 minutes.
