Concentrate

 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

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.
