FEATURES & OPERATING CONTROLS

A. THERMOSTAT

1. On THERMOSTATICALLY CONTROLLED warmers, power is
applied to the heating element according to the control knob
position and the actual temperature at the temperature sensing
thermobulb.

2. The desired temperature is controlled by rotating the
TEMPERATURE CONTROL KNOB. The knob has a numeric
scale, where higher numbers correspond to higher temperature.

3. On warmers equipped with an INDICATOR LIGHT, the light will
glow when the thermostat is calling for heat (i.e. the element is
energized).

4. The TEMPERATURE CONTROL KNOB will rotate
approximately 300º, and will reach a “stop” at both ends.
The OFF position is marked.

NOTE: The dial position is an indication of the temperature
setting. Actual temperature will vary depending upon the type of
product and food consistency.

B. MOUNTING

1. Top-mounted built-in warmers may be equipped with
WELLSLOKS, uniquely designed turnout tabs which help
secure the warmer top flange to the countertop.

2. Bottom-mounted warmers require that the cutout be flanged to
provide a mounting means.

3. See the Installation Instructions, supplied with the particular
appliance, for details.

C. DRAINS

1. AUTOFILL units (e.g. MOD-300TDM/AF) have their individual
drain fittings manifolded together, with a single drain valve for
the entire manifold.

D. AUTOFILL

1. On AUTOFILL units, water level is automatically fed into the
"master" pan whenever that pan's thermostat is ON .

2. Water level is sensed by a WATER LEVEL PROBE in the
"master" pan.
