6.1 DISPENSING, SERVABILITY AND OVERRUN
6.1.1 PRODUCT DISPENSES SLOWLY OR NOT AT ALL
CAUSE CORRECTION
No mix or very low mix in hopper. .............................. Add prechilled mix into hopper.
Mix inlet regulator orifice is too small. ........................ Use larger orifice, especially for thicker mixes.
Mix inlet regulator is plugged. .................................... Unplug using small sanitized brush or disassemble, and sanitize
................................................................................... all mix regulator parts.
Freezer is being overdrawn. ...................................... Slow down rate of draw.
Consistency setting is too soft or too firm. ................. Adjust fine consistency potentiometer accordingly. If more adjust-
................................................................................... ment is required, increase/decrease coarse amperage ‘AMP
................................................................................... CRS’ setting 0.5 amps with fine potentiometer at midrange
................................................................................... consistency procedure in subsection.
Hopper mix partially frozen, improperly thawed. ........ Thaw mix according to manufacturer’s instructions.
Door handle movement is too restricted. ................... Turn dispense rate adjuster counterclockwise.
Door port is blocked or frozen. ................................... Turn off power, remove door and frozen product/blockage. Prepare
................................................................................... mix according to manufacture’s instructions.
Auger flights and/or springs are worn or missing. ..... Replace flights and/or springs.
Control ‘LKG’ temperature is too high/low. ................ Control ‘LKG’ temperature should approximately
................................................................................... equal or slightly exceed desired product serving temperature;
................................................................................... change accordingly (refer to control setup procedure in subsec-
................................................................................... tion 3.2).
Freezer refrigerant charge is low. .............................. *Refer to Troubleshooting subsection 6.3.22.
Suction line solenoid valve has excessive seat
leakage; barrel is frozen. ........................................... *Replace the suction line solenoid valve.
Auger shaft not turning. ............................................. Check and replace belt, speed reducer or auger shaft.
6.1.2 PRODUCT IS TOO SOFT (SEE MIX CHARACTERISTICS SECTION)
CAUSE CORRECTION
Dispensed product with red P.T.F. light. ............ Dispense servable product with green P.T.F. illuminated.
Ambient temperature is high. ............................. Move or direct hot air away from freezer.
Mix inlet regulator air tube is plugged. ............... Unplug by using small sanitizes brush.
Freezer is being overdrawn. .............................. Slow down rate of draw.
Consistency setting is too soft or too firm. ......... Adjust fine consistency potentiometer firmer. If more adjust
.......................................................................... ment is required, increase coarse amperage ‘AMP CRS’
.......................................................................... setting 0.5 amps accordingly with fine potentiometer at mid-
.......................................................................... range (refer to control setup procedure in subsection 3.2). If
.......................................................................... unable to establish desired consistency, follow the coarse
.......................................................................... amperage consistency procedure in subsection 3.2.
