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 lower ledges of the cabinet. An electrical power cord is
provided and 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 and 900w heater element will operate
continuously while the unit is “ON”.
Analog Drawer
: 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; approx. 80 °F) to 9 (high heat;
approx. 185 °F). The right thermostat knob controls the humidity from 1 (approx. 20% relative humidity) to 9
(100% relative humidity). Average setting will be approx. 6 (approx. 85% relative humidity).
Digital Drawer
:The thermostat control buttons are located under each digital display “Heat Temperature”
or “Proof Temperature”. The heat controls in the cabinet range from low heat approx. 80 °F to high heat,
approximately 185 °F. The humidity controls in the cabinet range from approximately 20% to 100% relative
humidity. The average will be approximately 85% relative
humidity.

HEAT THERMOSTAT
The controlling range is 80°F to 185°F. The dial has numbers 1 thru 9 that do not relate to a specific
calibrated temperature. Temperature settings must be obtained through familiarization with the unit. The dial
also has an “OFF” position to turn heater unit off.
HUMIDITY THERMOSTAT
To control humidity range from 30% to 100%, humidity settings must be obtained through familiarization with
the unit. The dial has numbers 1 thru 9 that do not relate to a specific calibrated humidity. The dial also has
an “OFF” position to turn humidity off.
To maintain low heat range between 85°F and 100°F, switch to proof mode and adjust heat knob to
desired heat range. Allow 45 minutes to pre-heat in proof cycle.
