Controls

The merchandiser controls are shown in the figure below. The POWER switch turns the power supply to
the unit on and off. The LIGHTS switch turns the lights in the unit on and off. The POWER switch must be
turned on for the lights to operate.
The well and canopy heaters for each well section of the unit are individually controlled as shown in figure
above. (TSWHI units – the well and shelf heaters are individually controlled.) With the indicator on the
control knob turned to the 12 o'clock position as shown, the heaters produce no heat.
To increase the temperature of the lower well heater, rotate its control knob clockwise. Likewise, to
increase the temperature of the canopy heater, rotate its control knob counterclockwise.

Preheating

To preheat the equipment, position the temperature control knobs on each well to the number 5. You
should allow the equipment to preheat for a minimum of 30 minutes before loading it with product.
Each well is equipped with a pilot light indicator. The pilot light indicator is designed to turn OFF when the
well reaches set temperature. During operation the pilot light indicator will turn OFF and ON as the well
maintains proper temperature.
