between the unit and walls or other obstacles. Increase the
distanceiftheobstaclesareaheangsource.(Fig.1)
3. Leave 60 in. of free space in front of the machine to allow for
easyuseandmaintenance.(Fig.1)
4. Leave 10 in. of free space above the machine to allow for
removaloflids.(Fig.1)
5. Whenthemachineisinplace,adjusttherubberlegstolevel.
1. SettheMainPowerSwitchtoOFF(0).
2. Verify that the machine is properly grounded.
3. Verify the voltage of the outlet matches what is
indicated on the serial plate.
4. Verifythecurrentavailableissucientforthe
maximumrequiredbythemachine.
5. Inspectthecordfordamage,ifanyispresent
DO NOT plug into the outlet.
6. DONOTuseanextensioncordoradapterto
connect the machine to the electric supply.
• DO NOT touch the machine with wet hands or feet.

 Inordertoobtainahomogeneousmix,theproductwillneed
 tobepre-mixedbeforebeingaddedtothemachine.Followthe
 manufacturer’srecommendaonsformixing.
Ready-to-Use & Pre-Mixed Concentrates
1. Turn the machine OFF and unplug from power supply.
2. Pourliquidintothebowl.(Fig.2)
3. DO NOT pour below the MIN Level.
4. DO NOT pour above the MAX Level.
1. PosiontheBeverageTypeControlSwitchtoI(Slush/FrozenCreamMode).
2. PosiontheSpiralBladeSwitchtoI(ON).
3. Waitforthemixturetofreezeandtestconsistency.
Ifconsistencyisgood,connuetostep5.Ifnot,connuetostep4.
4. ThicknessControlKnobisfoundbehindthebackpanelofthemachine.
Themachineissetforopmalslushthicknessbythefactory,turnthescrew
LtoRtoincreasethickness,RtoLtodecreasethickness.(Fig.3)
5. Dispensethebeveragebypullingthetaplever.(Fig.5)
1. PosiontheBeverageTypeControlSwitchtoII(ColdDrinkMode).
2. PosiontheSpiralBladeSwitchto0(OFF).
3. Theopmaldrinktemperaturehasbeensetbythefactory.
UsetheThermostatControltoadjustthetemperatureofthedrink.
4. Tosettemperature,openthetransparentscreenonthefrontpanelbelowthe
bowl and turn the Thermostat Screw.
5. Dispensethebeveragebypullingthetaplever.(Fig.5)
Inordertoobtainaslushconsistency,themixturemusthavea
minimumsugarcontentof13°BRIX(13gsugarto100gsoluon).
Alowerconcentraonmaydamagethespiralbladesandgearmotors.
Prepare the product separately before proceeding.
It is recommended to maintain a product level above the cylinder evaporators
forconsistentcooling.(Fig.4)
Beforeusingthemachine,allfoodcontactsurfacesandcomponentsmustbecleaned
andsanizedinaccordancetotheWashing&Sanizingseconofthismanual.
