Equipment Description
The Groen NFPC is a stainless steel, electrically
heated Braising Pan which is equipped with
integrated heating elements, a power tilting
mechanism, electrical controls and a hinged
cover. The Braising Pan serves as a braising
unit, griddle, fry pan, oven, kettle, bain-marie, or
food warmer and server. It can also be adapted
for use as a non-pressure steamer.
Construction of the pan body employs heavyduty stainless steel welded into a solid piece. It
has a polished interior and a semi-deluxe
exterior finish. A pouring lip is welded to the top
of the front wall. The cooking surface is a
stainless steel clad plate fitting with clamped-on
electrical heating elements. The elements are
positioned to ensure uniform heat transfer over
the entire surface. The pan is mounted on an
open-leg frame which is fabricated from tubular
stainless steel.
An electrically powered mechanism tilts the pan
forward. A three position switch on the front of
the control console gives the operator positive,
smooth-acting control of tilt.
Heating elements and other electrical
components are enclosed for safety. The
thermostat, heating indicator light, and tilting
switch are contained in a compact control
console which is mounted to the right of the pan
body.
The thermostat provides automatic control of
cooking temperature. Turning the thermostat
dial starts and stops heating and sets the pan
temperature. Only one electrical connection is
required to install the unit.
A vented, heavy gauge, one-piece, stainless
steel cover with a rear condensate drip shield on
the underside is standard on the Braising Pan. A
fully enclosed spring-type actuator counter
balances the cover to maintain either the opened
or closed position. The cover opens to the back.
It is hinged to the frame, so it moves
independently from the pan body.

Installation
OM-NFPC
Internal wiring for the Braising Pan is supplied
complete. When you receive it, the unit is ready
for connection. A wiring diagram is inside the
control box on the right side of the pan, as well
as in this manual (Pp 14-21). Your pan was
operated and tested at the factory to confirm that
all controls and heating elements were
functioning correctly.
Installation is as follows:
1. Set the unit in place and level it by turning
the adjustable feet. Make sure the tilting
mechanism has been rotated to its lowest
position and check levelness by placing a
spirit level on the bottom of the pan. The
unit must be level to avoid uneven cooking
across the pan.
2. At the electrical service entrance in the
bottom of the control box, make a
waterproof connection with the incoming
power line. A BX connection is not
recommended.
CAUTION
ELECTRICALLY GROUND THE PAN AT THE
TERMINAL PROVIDED.
3. Provide the proper electrical supply as
specified on the electrical plate attached to
the equipment. Observe local codes
and/or the National Electrical Code in
accordance with ANSI/NFPA 70 — latest
edition.
WARNING
THE BRAISING PAN MUST BE INSTALLED
BY PERSONNEL WHO ARE QUALIFIED TO
WORK WITH ELECTRICITY. IMPROPER
INSTALLATION COULD RESULT IN
PERSONAL INJURY OR EQUIPMENT
DAMAGE.
4. Any mechanical or electrical change must
be approved by the Groen Food Service
Engineering Department.

Initial Start-Up
Now that the Braising Pan has been installed,
you should test it to ensure that it is operating
correctly.
1. Remove all literature and packing
materials from the interior and exterior of
the unit.
2. Turn on the electrical power to the unit.
3. Put enough water into the pan to cover its
bottom to a depth of ¼” to ½”. With the tilt
mechanism still cranked all the way back
to the horizontal position, note how the
water covers the pan bottom. This is a
good method to confirm that the unit is
properly leveled.
Operation
Operator Controls on the Braising Pan are the
thermostat dial and power tilt switch on the
console to the right of the pan body. The dial
turns electric power for the pan on or off, and
sets the pan’s operating temperature. The
power tilt switch is used to raise or lower the pan
body. Press the switch down to raise the pan
or up to lower it.
A. Start-up Procedure
4. Set the thermostat to 235o F. The heating
indicator light should come on to indicate
that the pan is heating. Heating should
continue until the water boils.
5. To shut the unit down, turn the thermostat
dial to “OFF.”
CAUTION
STAND AWAY FROM THE HOT WATER
WHILE TILTING THE PAN TO EMPTY IT.
6. Position a container for the pour-off and
press down on the power tilt switch so that
the water pours out. This will confirm that
the pan body can be tilted from horizontal
to vertical.
B. Cooking
1. To simmer or slowly heat an item, set the
dial at about 210o F or lower. Put the
cover down to keep moisture loss at a
minimum, or leave it up to help dry the
product. Set the thermostat higher to cook
or drive moisture off faster. The
thermostat may be adjusted to any setting
in its range to cook exactly as you wish.
1. Set the thermostat dial to the desired
temperature between 100 and 400o F. The
glowing Heat Indicator Light shows that
the pan is heating. When the light cycles
on and off, it indicates that the pan is being
held at the set temperature. Once in each
of these cycles you may hear the
contactors in the control box make a
clicking sound.
2. For best results when braising or frying,
preheat the pan before putting in any food.
For an even temperature across the pan,
reheat at a setting of 300o F or less for 15
minutes, or through several on/off cycles
of the thermostat.
WARNING
DO NOT HEAT AN EMPTY PAN FOR MORE
THAN FIVE MINUTES AT SETTINGS ABOVE
300oF. DAMAGE TO THE PAN COULD
RESULT.
2. Leave the cover vent open to allow excess
steam to escape. For longer simmering,
you may wish to close the vent.
WARNING
AVOID ANY EXPOSURE TO THE STEAM
ESCAPING FROM THE COVER VENT.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS
3. To check cooking progress when the
cover has been closed, grasp the plastic
handle of vent cover and lift it slightly while
moving it quickly to either side. Standing
at one side of the pan to avoid the steam
that will be released, grasp the nearest
corner of the cover handle and raise the
cover. The cover will stay in the open
position until you put it down.

4. To pour or dump product, remove grease,
or assist cleaning, first raise the cover,
then tilt the pan up and forward by pushing
down on the power tilt switch. Whenever
you release the tilt switch the pan body will
hold its position.
OM-NFPC
5. To return the pan to the horizontal
position, pull the switch up.
6. If the power tilt mechanism stops working
(See the Trouble Shooting Section) and
you must raise or lower the pan body
without delay, you can tilt the body
manually. Fit the provided hand crank
onto the slotted shaft end that protrudes
from the actuator motor (the end facing
the front of the unit). Turn the crank
clockwise to lower the pan or
counterclockwise to raise the pan.
WARNING
AVOID ALL DIRECT CONTACT WITH HOT
EQUIPMENT SURFACES. DIRECT SKIN
CONTACT COULD RESULT IN SEVERE
BURNS.
AVOID ALL DIRECT CONTACT WITH HOT
FOOD OR WATER IN THE BRAISING PAN.
DIRECT CONTACT COULD RESULT IN
SEVERE BURNS.
IF THE PAN CONTAINS ITEMS IN SAUCE OR
MELTED FAT, THEY COULD SLIDE
FORWARD SUDDENLY DURING TILTING
AND CAUSE THE HOT LIQUID TO SPLASH
OUT.
7. Manual cranking will take several minutes,
but the operation can be speeded up by
using a reversible electric drill with a
screwdriver bit in place of the hand crank.
C, Routine Clean Up
After each use, turn the thermostat to
“OFF” and clean all food contact surfaces
to ensure proper sanitation. At the end of
the day, or at least once every 24 hours,
turn off the heat and shut off electric power
to the unit and clean both the interior and
exterior of the pan. See Page 9 for more
detailed cleaning instructions.
The pan body may also be tilted manually using
a hand crank on the slotted shaft of the actuator
motor.

Sequence of Operation
The following “action-reaction” outline is provided
to help you understand how the braising pan
actually functions.
When you start up the pan by turning the
thermostat from “OFF” to a desired temperature,
the thermostat switch closes. This causes the
contactors to close, and allows power to flow to
the heating elements and the indicator light.
When the pan temperature reaches the value
set on the thermostat dial, the thermostat switch
opens and causes the contactors to open. This
stops the flow of power to the heating elements
and the indicator light.
As soon as the thermostat senses that the pan is
cooling below the set temperature, the
thermostat closes, the contactors close, and the
heaters and indicator light come on again.
This on and off cycle continues, maintaining the
pan at the set temperature. This is why the
indicator light on and off cycling is seen during
normal operation.
The thermostat controls heating by alternating
between feeding full power and completely
cutting power off. The pan heats as fast as it
can until it reaches the set temperature, no
matter what that temperature is. Turning the
thermostat to a higher setting will cause heating
to continue longer, until the pan reaches a higher
temperature, but it cannot make the pan heat
any faster.
The power tilt switch controls a reversible motor
that drives a ball screw mechanism. When the
switch is held in the lowered position, the
mechanism raises the pan body. The body rests
on a trunnion near the front corners, so it tilts
forward until the switch is released or the body
reaches its vertical limit.
If the tilting motor gets too hot during operation,
an overheat protection switch will open and stop
the motor. When the motor has cooled
sufficiently, the switch will automatically reset
and permit tilting to begin again.
If the pan temperature exceeds 425o F for any
reason, a high-limit thermostat shuts off the
power until the pan cools. At that point, the
thermostat automatically resets to permit normal
operation to start again.
Turning the thermostat to “OFF” shuts down all
control and heating circuits.
