Emery Thompson CB-350 Countertop Batch Freezer
Ideally the low-pressure side should drop to 28 to 32 psi and the high-
pressure side should run at 275 to 325 psi. During the last several
minutes of a batch you may see the low-pressure side drop again by
about 2 psi.
When the product is ready, the refrigeration button is turned off and the
solenoid valve closes and the contacts in CR-1 open. The compressor
continues to run until the low-pressure side of the refrigeration system
drops below 10 psi and the low-pressure switch opens.
When the low-pressure switch opens, the coil is no longer energized,
and the motor contactor opens causing the condensing unit and cooling
fan to stop.
When the STOP button on the touchscreen is pressed, the dasher motor
speed controller stops sending power to the dasher motor and the motor
stops.
