Operator Controls and Indicators
The following table describes the operator controls and indicators. Refer to the photo above for location of these controls and indicators on the freezer.
NOTE: The dispense head must be in place before the freezer will operate.
|Day-Night Switch (1)||
Do not use the “AUTO” position with water or sanitizer in the cylinder or hopper. The freezer will be damaged.
|Reset — Overload (3)||If the overload trips frequently, your freezer should be checked for proper product temperature, overrun and voltage. Contact your Electro Freeze Distributor.
This control protects the beater motor against failure from an overload condition by automatically shutting down the freezer. To restart the freezer properly, turn the SELECTOR switch to “OFF”, wait 2-3 minutes, then depress the red reset button and turn the SELECTOR switch back to the “AUTO” or “CLEAN” position.
|Timer (4)||This control will bypass the thermostat, forcing the compressor and beater motor to run up to 3 minutes. Use the timer for quick start-ups or fast recovery when dispensing large portions.
Excessive use of the timer causes freeze-up and damage to the freezer.
|“ADD MIX” Indicator Light (5)||When blinking, this light indicates the mix in the hopper is at a low level and should be refilled as soon as possible. Always maintain at least 2 inches (5.1 cm) of mix in the hopper. For best operating results, keep hopper full.
If proper mix level is not maintained, a freeze-up may occur and may damage the freezer.
Mix Feed Tube & Regulator
This three-position regulating device meters the correct amount of mix and air into the freezing cylinder.
- Locate the round indent near the top of the mix tube cylinder. Align this indent to the center range of the three indent pattern on the mix feed regulator.
- The plastic mix feed regulator may be adjusted within the three indent range to obtain an optimum product overrun and dispense speed.
- The largest indent setting will allow the least overrun. The smallest indent setting will allow the most air in the cylinder and is used for a higher overrun. (see figure 5-4)
During periods of idle or night operation, place the mix inlet port to the closed position. At this setting, mix and air flow are shut off to the cylinder.
Important: If product is dispensed when the regulator is in the "CLOSED" position, a freeze-up will occur and may cause damage to the freezer.
