Mix Low Function These models will sense when the mix is low in the hopper On 3341 and 3342 models a simple float mechanism is used to sense when mix is low in the hopper see Figure G When the mix level is low the mix low light located on the front of the machine will illuminate NOTE Do not run the unit under mix low conditions for long periods of time This can affect machine performance or damage componentry On 3341A and 3352 models mix low is sensed via the autofill system When the mix level is low the mix low light will illuminate continuously for 2 minutes After 2 minutes the light will begin to blink off and on for the next 8 minutes At the end of the 10 minute time the light will illuminate fully again After the 10 minute cycle the mix out safety function is activated making the unit inoperable The safety function shuts off the autofill and refrigeration The unit can be reset back to the freeze mode by simply adding mix into the hopper NOTE If the mix low safety function has activated disabling the unit and the product has not been added for an extended period of time verify the product is okay for re use If it is not use fresh product to restart the unit Empty the unit of old product and follow cleaning and sanitizing procedures page 8 Consistency Adjustment From time to time it may become necessary to readjust the consistency setting thickness to compensate for variation between different mixes or to sw
