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

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.

Heat Knob (Heat Mode)

The controlling range is 80° to 185°F ( 26° to 85°C) temperatures vary slightly between insulated and non-insulated
units. The dial has setting from 1 to 9 that do not relate to any specic calibrated temperatures. Temperature settings
must be obtained through familiarization with the unit. While in the heat mode this knob controls the two elements in
the air stream, in the “OFF” position the elements are turned off. During the “Proof” mode one of these elements is
not in use.

Humidity Knob (Proof Mode)

To control the humidity range from 30% to 100% humidity, settings must be obtained through familiarization with the
unit. The dial has a range of 1 - 9 which determins the temperature of the water in the pan, if you have the knob in the
“OFF” position it will turn the proong element off. While in proof mode the unit will operate at a lower termperature.

Allow 45 minutes to pre-heat in both heat & proof cycle.

TROUBLESHOOTING

CAUTION: Before disassembling unit, electrical power must be disconnected by unplugging the unit. Failure to

unplug the unit prior to servicing may result in electrical shock.

Each unit is shipped with an instruction manual to be used as a reference guide for all service areas. The manual
shows a picture of the drawer, showing the location of electrical components and a description of each. If the unit
does not operate correctly, or malfunctions for any reason, the following checklist should provide a solution.

1) Check to make sure cord set is rmly plugged into the power receptacle in the back of the cabinet and
into the wall outlet.

2) Check circuit breaker of wall outlet and reset if necessary.

3) Remove heat drawer from cabinet. Remove bottom cover of drawer. Visually inspect for:

a) Loose or disconnected wires

2M-Z18494, Heater Proofer 9451- Series

b) Black marks or burning on any components

c) Loose heating elements.

4) If any burn marks or discoloration of wires is note on any components along with all wires attached to
damaged components must be replaced.

5) If heater element is loose, or if it has broken loose from mounting tabs, the wires will short out on the
Metal, causing permanent damage. Both the element and main power switch (with wires on switch) must
be replaced.

6) If temperature on “L.E.D. Thermometer” is not reading a constant temperature, it must be replaced. If

temperature has exceeded 200°F (93°C) it must be lowered immediately to maximum temperature of

185°F (85°C).
