Soft Serve: Programming Inverter

SS: Programming Inverter


How-To Guide :: Soft Serve :: Programming Inverter

Spaceman soft serve machines transitioned to soft-start three phase motors beginning in 2020.  This change began with models that have a -C in the model name.  These newer models have a power inverter that converts single-phase 220VAC power to drive a 3-phase 220VAC motor.  When replacing the inverter, it may be required to program the new inverter to have the appropriate settings for your machine.  For information on how to replace the inverter, please see the SS: Replacing Inverter article.

Part Ordering:  Replacement inverters can be purchased at PartsTown.
