Set Point 1 Remove top plate to the freezer by removing the four screws on each corner 2 The recommended operating pressure for the compressor is between 10 25 psi The remote located product storage tank s will operate safely up to 25 psi The differential should be 5 to 7 psi NCAUTION The use of excessive pressure above 25 PSI will result in relief venting at the product tank s Adjustment The scale plate directly indicates the cut out and differential The cut in is calculated by subtracting the differential from the cut out 1 Adjust the range screw until the scale pointer indicates the desired cut out setting 10 25 psi 2 Adjust the differential screw until the scale pointer indicates the desired differential setting 5 7 psi The cut in setting equals the cut out setting less the differential Mix Product for the Storage Tanks For the dispenser to operate properly the percent of dissolved solids generally sugar in the pre mix product should be between 11 and 14 as measured by a refractometer referred to as Brix If the Brix of the pre mix product is below 11 the product will freeze too hard and result in auger freeze up If the pre mix product Brix is above 14 the product will not freeze quickly and will remain liquid NOTE Brix is the percentage of sugar in the mix The instrument called a refractometer reads Brix directly A refractometer can be purchased from Grindmaster Corporation or most beverage supp
