Operating Instructions

1. Set the bun adjustment controls (Figure 6) to desired setting.

NOTE: After initial run of 4-6 buns, adjust controls according to the desired finished product.

2. Turn the rocker switch on (Figure 5). Allow 30 minutes warm-up time before proceeding.

NOTE: The temperature display (Figure 5) will flash “LO” until preset operating temperature is reached. When the toaster approaches the preset temperature of 560°F (243°C), “560°F” will appear in the temperature display and the unit is ready to toast buns.

The toaster is tested and shipped with the heaters set at a preset recommended temperature. If “560°F” does not appear in the window after warm-up period, see Temperature Adjustments below for recommended temperature settings and to adjust temperature settings.

3. Drop buns into toaster (Figure 5). Cut sides of

heel and crown must face each other (crown in front, heel in back).

4. Toasted product will drop into the bun landing area (Figure 5).

5. Test at least 4 buns before putting toaster into service.

6. Turn the rocker switch off when finished toasting.

Temperature Adjustments

The VCT-20 uses a platen heater and two auxiliary heaters. The platen heater consists of a heating coil built into the platen to toast the cut side of the bun. The two auxiliary heaters assist in providing additional heat to the buns. The first auxiliary heater is located between the conveyor in the front of the toaster. The second auxiliary heater is located between the conveyor and the rear of the unit.

RECOMMENDED TEMPERATURES

Recommended temperature setting for the platen heater is 560°F (293°C).

Recommended temperature setting for the auxiliary heaters is 340°F (171°C).

NOTE: The toaster is tested and shipped with the heaters set at the above recommended temperatures.

Safety Features

HI-LIMIT RESET BUTTON

A hi-limit thermostat will turn off electrical power to the heater and control circuits if the unit overheats. To reset this thermostat, allow sufficient time (10-15 minutes) for the unit to cool down, then depress the reset button located on the rear of the unit (Figure 5).

If the unit requires continuous resetting, contact your Roundup authorized service agency.

FAULT MESSAGES

• If the platen thermocouple is disconnected or “open”, the display will read “HI” and the heating circuit will turn off (Figure 10). The platen thermocouple must be reattached or replaced.

• If the platen heater temperature exceeds 591°F (310°C) the display will read “HI” and the heating circuit will turn off (Figure 10). After the toaster has cooled down, the unit must be turned off, then back on to restart. If this condition repeats, contact your Roundup authorized service agency.

• If the auxiliary heating temperature exceeds 360°F (182°C) the display will alternately flash “HI” and the platen setpoint temperature (Figure 10). The heating circuit will not turn off. The toaster must be manually turned off and allowed to cool down. After the toaster has cooled down, the unit must be turned back on. If this condition repeats, contact your Roundup authorized service agency.
