3.11SO328 OPERATION INFORMATION FOR SERVICE PERSONNEL

The SO328 is a cocktail/slush freezer. It is available in 208-230 volt, either air-cooled or water-cooled. The air- cooled version has front-to-back airflow requiring three inches of air space in the front and back for proper refrigeration. This unit is not supplied with a pump, however, Stoelting does offer the Fill-O-Matic II (electric) and Fill-O-Matic III (gas) pumps. This freezer is intended for use with non-dairy products only and will produce 15-18 GPH.

1. Filling

To fill the freezer, pour mix into hopper until full. To fill freezers with the optional Fill-O-Matic pump, connect the pump and turn the pump switch on, electric model or turn the gas on, gas model. Then turn the pump switch on, located on the freezer, this will open the solenoid valve and the freezer will begin to fill. The liquid level control circuit is designed with a fill timer. This timer is designed to shut the compressor off if the top level probe is not satisfied before the timer expires. If the top level probe is not satisfied before the timer times out, it locks the compressor out and freezing will not occur, if this happens, turn the fill switch off and then back on, this will reset the timer.

2. Operation

Once the freezer is full of mix, turn the clean-off-serve switch to the “serve” position. The drive motor will start immediately. The compressor utilizes a 10 second delay-on-make / delay-on-break timer therefore, the compressor will start 10 seconds later. The compressor will continue to run until the drive motor torque switch is satisfied, then after a 10 second delay stop. The drive motor runs continuously in the “serve” or “clean” switch positions. There is no night mode or standby mode. If product is left in the freezer overnight we recommend to simply turn the freezer off. Do not run the freezer in "clean” overnight. Freeze down time will typically be 6- 10 minutes depending on the type of product used and the starting product temperature.

3. Pump Operation

When the mix level in the hopper drops below the bottom level probe, the solenoid valve opens and the pump begins to fill until the top level probe is satisfied. When satisfied, the solenoid valve closes, and pump will continue to run until shut off pressure is reached. The electric pump will run until the pressure reaches the cut-out pressure of the pump. A gas pump will continue to run until the pressure in the mix line equals the gas pressure of the pump. If you wish to use the product in the hopper prior to cleaning, turn the mix pump off and turn the freezer pump switch off. This will disable the fill timer and allow the compressor to continue to run. Be cautioned that once the hopper is empty, the barrel could freeze up. Only run the freezer until the hopper is empty or damage may occur.
