B. Settings and Adjustments
1) VR1 Harvest Control
VR1 harvest control is for adjustment of the harvest cycle completion temperature.
Factory set, do not adjust.
NOTICE
Do not adjust VR1 harvest control. VR1 harvest control is factory set for proper
operation. Adjustment outside of the factory default setting will result in freeze up
and/or damage to the appliance.
a) Initial Harvest: Terminated by 50 sec. harvest timer. No temperature requirement.
b) Normal Harvest: Terminated by temperature (47°F (7°C)) and time (50 sec. harvest
timer).
Once the thermistor warms to 47°F (7°C), CB reads 4.5 kΩ from the thermistor and
turns harvest termination over to the 50-sec. harvest timer.
2) VR2 Freeze Control
VR2 freeze control is for adjustment of the freeze cycle completion temperature
(controls size of hole in ice cube). If adjustment to cube hole size is desired, follow the
instructions below. See Fig. 1.
NOTICE
Do not adjust VR2 to the lowest temperature setting. This will result in freeze up.
a) Larger Hole: Turn VR2 freeze control clockwise for a higher freeze cycle completion
temperature (WARM) for shorter freeze time and ice cubes with larger diameter
holes.
b) Smaller Hole: Turn VR2 freeze control counterclockwise for a lower freeze cycle
completion temperature (COLD) for longer freeze time and ice cubes with smaller
diameter holes.
