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 heavy- duty 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.

OM-NFPC

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.
