9451 HP SERIES SERVICE SPECIFICATIONS

The Heater Proofer is an aluminum transport cabinet with heaters to function

as a hot food holding cabinet, and/or as a proong cabinet.

The heater, or heat drawer, is slid into place on the oor 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 185°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).

INSTALLATION

This unit is equipped for the voltage indicated on the nameplate mounted the side of the unit. They will

operate on alternating current (AC) only.

The electrical connection must be made in accordance with local codes or in the absence of local codes

with NFPA No.70 latest edition (in Canada use: CAS STD. C22.1). The electrical service is provided by a
cord and plug. Each appliance requires a 120 volt grounded supply. Supply wires must be 14 gauge or

larger to carry the load for one proofer.

DO NOT CONNECT TO DIRECT CURRENT (DC).

THIS APPLIANCE IS EQUIPPED WITH A 3-PRONG (GROUNDED) PLUG FOR YOUR
PROTECTION AGAINST SHOCK HAZARD AND MUST BE PLUGGED DIRECTLY INTO A
PROPERLY GROUNDED 3-PRONG RECEPTACLE.

GENERAL OPERATING PROCEDURES

Proong

Proong is one of the most important and delicate stages in baking. About 50% of the product volume
is created in the proofer. Proong accelerates the fermentation of yeast in a warm moist environment

causing the dough to rise. The proofer humidity should be between medium high and high. For optimum
results, rolls should be removed from the hot proofer and transferred to the cold proofer at minimum
proof. This will ensure that they can be held for 40 minutes without becoming over-proofed.
