SERVICE SPECIFICATIONS – E17UAC
The Heater Proofer is an aluminum transport cabinet with heaters to function as a hot food
holding cabinet, and/or as a proofing cabinet.
The heater, or heat drawer, is slid into place on the floor of the cabinet. An electrical socket on
the back of the drawer is provided to accept the supplied power cord, which is plugged into the
drawer through an access hole in the back of the cabinet.
The main power switch on the front of the drawer, when switched “ON”, will turn on the light in
the switch and turn on the air circulating fan in the drawer. The circulating fan will operate
continuously while the unit is “ON”.
The thermostat control knobs are mounted to the left and right of the heat/proof switch. The left
thermostat knob controls the heat in the cabinet from 1 (low heat: approximately 80°F) to 9 (high
heat: approximately 175°F). The right thermostat knob controls the humidity from 1
(approximately 20% relative humidity) to 9 (in excess of 100% relative humidity). Average
setting will be approx. 6 (approximately 85% relative humidity).
