Equipment Description

The following dimensions apply to CE model HFP braising pans:

Model Width Depth Height Weight (Kg) Weight (lbs)
HFP/2E-3/2E-3 1245 mm 960 mm 1780 mm 241 530
HFP/2E-4/2E-4 1500 mm 960 mm 1780 mm 270 593

Groen Gas Heated Braising Pans provide a stainless steel pan equipped with patented heat transfer fins,
burner/combustion chamber, hand-operated tilting mechanism, thermostatic controls, and hinged cover. The
Braising Pan serves as braising unit, griddle, fry pan, oven, kettle, bain-marie, or food warmer and server, and it
can be adapted for use as a steamer.

The pan body is made from heavy-duty stainless steel welded into one solid piece, with a polished interior and
exterior. A pouring lip is welded to the front wall. The cooking surface is a stainless steel clad plate fitted with
welded heat transfer fins which assure uniform heat transfer over the entire surface. The gas burner/combustion
chamber supplies the heat.

An easily-operated worm and gear mechanism tilts the pan and provides precise control for pouring or dumping
the contents of the pan. This hand-wheel controlled mechanism is located in a stainless steel console to the right
of the pan body. To assist cleaning, the pan body can be tilted past the vertical position. When the pan is tilted, the
burners shut off automatically.The thermostat provides automatic control of cooking temperature. Operating the
thermostat dial on the front of the control console turns the heat on or off and sets the pan temperature.

A vented, heavy gauge, one-piece, stainless steel cover with a condensate drip shield on the rear edge is standard
on the Braising Pan. A fully enclosed, spring type actuator counter-balances the cover to keep it in either the
opened or closed position. The cover opens to the back and is hinged to the frame, so it moves independently of
the pan body.

Options available with the listed models are:

1. Fill faucet with swing spout.

2. Caster mounting kit.

3. Fold-down work tray (pan support) mounted on left or right side. (Factory installed option)

4. 2” Tangent draw-off. (Factory installed option)

5. Model REJ Steamer Insert set.

6. Steamer pan Carrier.

7. Quick gas disconnect with restraining cable

IMPORTANT

BEFORE ATTEMPTING ANY SERVICING, ENSURE
THAT THE ISOLATING COCK IS TURNED OFF AND
CANNOT BE INADVERTENTLY TURNED ON.
ENSURE ALSO THAT THE ELECTRICITY SUPPLY IS
DISCONNECTED.

AFTER ANY SERVICING OR EXCHANGE OF GAS
CARRYING COMPONENTS — ALWAYS CHECK
FOR GAS SOUNDNESS!

Note: When replacing wiring connections refer to

the wiring diagram in the unit or this manual.

3.1.1 After Servicing
a) Test for gas soundness as specified in IGE/UP1

as appropriate after any gas connection has been
disturbed.

b) Check for correct operation as appropriate (see

Installation, Section 1.5).

3.1.2 Regular Servicing Procedures
The following must be checked at regular intervals:
a) Burners

Clean the burners periodically to maintain
maximum performance. Burners are best
cleaned with a stiff bristle brush, or if necessary
with a wire brush. Take care not to damage the
burner.

Clean the injector orifice with a wooden splinter or
toothpick. Avoid metal reamers, which may
distort or increase the orifice size.

b) Gears

The gear housing has been fitted for proper
lubrication of moving parts. Since the gears do
not run in oil, periodic lubrication with grease is
essential. Frequency of lubrication depends on
operating conditions, but should occur at least
once every six months. Groen recommends the
use of a Number Two grade LGI lithium grease.
Add grease through the Zerk fittings on the gear
housing until grease flows out of the bearings
around the trunnion shaft. Place a liberal amount
of grease on the gear to cover the arc that is in
contact with the worm gear.

OSM-HFP/2E-CE

4.1Lighting and Operation

a) Check that gas and electricity mains are on.
b) Turn the toggle switch (Main Control Box) to the

“ON” position. The power neon (Main Control
Box) will illuminate.

c) Turn the thermostat (Upper Control Box) to the

desired setting.

d) Observe that the burners light by the lighting of

the heat neon (Main Control Box) (approximately
10-15 seconds).

e) Should the unit fail to light, it will lock-out, and the

Lockout neon will illuminate (Main Control Box).
Turn the unit off and wait for one or two minutes

before attempting to switch it on again.
f) Press the Reset Button once.
g) Repeat steps b through e.

CAUTION
IF THE RESET LIGHT COMES ON REPEATEDLY,
DO NOT OPERATE THE APPLIANCE. CALL FOR
SERVICE OR A QUALIFIED PERSON TO
INVESTIGATE.

For frying, the depth of oil in the pan must never
exceed the maximum oil level mark on the inner
pan wall.

WARNING
DO NOT OVERFILL WITH OIL OR FIRE MAY
RESULT.

4.4 Users’ Thermostat

Provides automatic control of the braising pan
temperature at selected temperatures up to a
maximum of 190ºC.

4.5 Sequence of Operation

The following “sequence of operation” is provided to
help the user understand how the unit functions.

a) Switching the On/Off switch to the On position to

start the appliance causes the power neon to
illuminate.

b) Turning the thermostat sends a signal to the

ignition module.

4.2 To Shut Down Braising Pan

a) Turn thermostat dial to the Off position.
b) Switch the On/Off switch to the Off position.
c) For a prolonged shut down —

— Follow steps a and b
— Turn the gas and electricity mains off

d) Turn the tilting handle clockwise to pour out the

water or contents.

4.3 Filling the Braising Pan

Using hot water and detergent, clean out the pan
thoroughly prior to operation.

The pan should not be overfilled, and an allowance
should always be made for expansion and foaming of
the food being cooked.

c) The ignition module opens the multi-functional

control valve which allows gas to flow at a low
rate to the main burner. It simultaneously starts
a sparking sequence at the burner.

d) The spark ignites the main burner on low flow.

Once this occurs, the flame sensing probe
detects the flame. This confirms that lighting has
been successful.

e) The sparking/ignition sequence shuts off, and the

“Heat” neon illuminates.

f) After a short period of time the multi-functional

control valve opens to full flow and brings the
burners up to their maximum rate.

g) If, however, a burner flame is not detected within

15 seconds, the ignition module goes into lock­out mode, and the lockout neon is lit.

h) To restart the ignition sequence the unit must be

reset by depressing the Reset button on the front
of the control cabinet.

i) In addition to the gas lockout, other safety

features include:

15

OSM-HFP/2E-CE

— A high limit safety thermostat which cuts off

the gas supply should the operating
thermostat fail (i.e., should the temperature
exceed operating limits).

— A tilt switch which automatically cuts off the

gas supply when the unit is tilted when in
operation.

j. When the pan reaches a set temperature, the

thermostat switch opens. This halts the signal to
the gas control valve and causes the valve to
shut off the flow of gas.

k) When the pan cools below its set temperature,

the thermostat switch closes and starts another
heating cycle. This on-off cycling continues,
keeping the pan at the desired temperature.

4.6 To Empty the Pan

Turn the hand crank on the front of the cabinet
clockwise to tilt the pan body forward. The pan will
stay in position when you stop turning the handle. To
return it to the upright position, turn the crank anti­clockwise.

WARNING
DO NOT STAND IN FRONT OF THE PAN WHEN

TILTING IT. BE CAREFUL TO KEEP HOT
CONTENTS FROM SPILLING. KEEP PEOPLE
AWAY FROM WHEN EMPTYING THE PAN.

4.7 Power Failure

a) If power to the unit is lost, do not attempt to

operate the appliance until the electricity has
been restored.

b) When the power comes on again, follow the

steps in Paragraph 4.1, Lighting and Operation.

5. Cleaning

WARNING
DISCONNECT ELECTRICAL SUPPLY BEFORE ANY CLEANING. KEEP WATER AND SOLUTIONS OUT OF
CONTROLS AND BURNERS. NEVER SPRAY OR HOSE THE CONTROL CONSOLE OR ANY ELECTRICAL
CONNECTIONS.

1. Before any cleaning operation, shut off the
burner by turning the thermostat dial to "OFF". If
water or cleaning solution will be sprayed, unplug
the unit from the electric power source, or shut
off the power at the circuit breaker or fuse panel.

2. Clean all food-contact surfaces soon after use,
before the pan has cooled completely. If the unit
is in continuous use, thoroughly clean and
sanitize both interior and exterior at least once
every 12 hours.

3. Scrape or rinse out large amounts of food
residues, then wash the inside of the pan body
with a mixture of hot water and soap or an
appropriate detergent, such as Mikro-Quat from
ECOLAB. Follow the detergent supplier's
recommendations on strength of the solution to
use. Rinse the pan thoroughly with hot water and
drain completely.

MOST CLEANERS ARE HARMFUL TO THE SKIN,
EYES, MUCOUS MEMBRANES AND CLOTHING.
PRECAUTIONS SHOULD BE TAKEN TO WEAR
RUBBER GLOVES, GOGGLES OR FACE SHIELD
AND PROTECTIVE CLOTHING. CAREFULLY
READ THE WARNINGS AND FOLLOW THE
DIRECTIONS ON THE LABEL OF THE CLEANER
TO BE USED.

4. To remove materials stuck to the equipment, use
a brush, sponge, cloth, plastic or rubber scraper,
or plastic wool along with the detergent or soap
solution. To minimize the effort required in
washing, let the detergent solution sit in the pan
and soak into the residue, or heat the detergent
solution briefly in the pan. Do NOT use any
abrasive materials or metal implement that might
scratch the surface, because scratches make the
pan hard to clean and provide places for bacteria
to grow. Do NOT use steel wool, which may
leave particles imbedded in the pan surface and
cause eventual corrosion and pitting.

CAUTION

16

OSM-HFP/2E-CE

4. As part of the daily cleaning program, clean all
external and internal surfaces that may have
been soiled. Remember to check such parts as
the underside of the cover, control console, etc.

6. Controls and the control console may be cleaned
with a damp cloth.

7. The exterior surface of the unit may be polished
with a recognized stainless steel cleaner, or with
water and detergent.

8. If the equipment needs to be sanitized, use a
sanitizing solution equivalent to one that supplies
200 parts per million available chlorine. Obtain
advice on the best sanitizing agent from your
supplier of sanitizing products. Following the
supplier's instructions, apply the sanitizing agent
after the unit has been cleaned and drained.
Rinse off the sanitizer thoroughly.

NOTICE
NEVER LEAVE A CHLORINE SANITIZER IN
CONTACT WITH STAINLESS STEEL SURFACES
LONGER THAN 30 MINUTES. LONGER
CONTACT CAN CAUSE CORROSION.

9. If there is difficulty removing mineral deposits or
a film left by hard water or food residues, clean
the pan thoroughly and then use a deliming
agent, such as Groen De-limer De-Scaler (Part
Number 114800) or Lime-Away from ECOLAB, in
accordance with manufacturer directions. Rinse
and drain the unit before further use.

10. If especially difficult cleaning problems persist,
contact your cleaning product representative for
assistance.

Don’t use metal implements or steel wool to
clean the braising pan.

Use a brush, cloth, sponge or other non-abrasive
tool for cleaning.

6. Safety Precautions

A stop-cock will be fitted in the gas pipe supplying the appliance. The user must be familiar with its location and
operation, and able to turn it off in an emergency.

If there is a smell of gas, immediately turn off the gas, ventilate the area, and call the gas supplier.

NEVER USE NAKED FLAME TO SEARCH FOR GAS LEAKS.

17

OSM-HFP/2E-CE

7. Maintenance

Your Braising Pan is designed to require minimum
maintenance, but certain parts may need
replacement after prolonged use. After installation,
no user adjustment should be necessary. If a service
need arises, only authorized personnel should
perform the work.

WARNING
ELECTRIC POWER ALWAYS SHOULD BE
