SECTION 1. INTRODUCTION

1-1. PRESSURE FRYER The Henny Penny Pressure Fryer is a basic unit of food pro-

cessing equipment which is used only in institutional and
commercial food service operations.

P-H-T A combination of Pressure, Heat, and Time is automatically

controlled to produce the optimum in a tasty, appealing
product.

Pressure Pressure is basic to this method of food preparation. The pres-

sure is developed from the natural moisture of the food. The
patented lid traps this moisture and uses it as steam. Because
the steam builds rapidly, a greater part of the natural juices
are retained within the food. An operation valve vents excess
steam from the pot and maintains constant live steam pressure.

Heat Heat generated is another important factor of the pressure fryer.

Energy savings is realized due to the unit’s short frying time,
low temperature, and heat retention of the stainless steel
cookpot.

Time Time is important because the shorter time involved in frying

foods results in additional economies for the user. Foods are
table ready in less time than it would take to fry them in a con­ventional open-type fryer.

1-2. PROPER CARE As in any unit of food service equipment, the Henny Penny

Pressure fryer does require care and maintenance. Require­ments for the maintenance and cleaning are contained in this
manual and must become a regular part of the operation of the
unit at all times.

1-3. ASSISTANCE Should you require outside assistance, call your local

distributor in your area, or call 1-800-417-8405 or
937-456-8405.

201 1-1

The Henny Penny Pressure Fryer has many safety features
incorporated. However, the only way to ensure a safe operation
is to fully understand the proper installation, operation, and
maintenance procedures. The instructions in this manual have

related, the words DANGER, WARNING, CAUTION, and
NOTE are used. Their usage is described below.

The word DANGER indicates an imminent hazard
which will result in highly serious injury such as second
or third degree burns, loss of sight, and other perma­nent injuries.

The WARNING is used to alert you to a procedure,
that if not performed properly, might cause personal
injury, such as burns and/or loss of sight, and damage
to the fryer.

The word CAUTION is used to alert you to a procedure
that, if not performed properly, may damage the fryer,

The proper location of the fryer is very important for opera­tion, speed, and convenience. Choose a location which will
provide easy loading and unloading without interfering with
the final assembly of food orders. Operators have found that
frying from raw to finish, and holding the product in a warmer
provides fast continuous service. Landing or dumping tables
should be provided next to at least one side of the fryer. Keep
in mind the best efficiency will be obtained by a straight line
operation, i.e. raw in one side and finished out the other side.
Order assembly can be moved away with only a slight loss of
efficiency.

For proper operation, the fryer must be level from side to side
and front to back. Using a level placed on the flat areas around

the frypot collar, adjust the casters until the unit is level.

The fryer should be located with provision for venting into ade­quate exhaust hood or ventilation system. This is essential to
permit efficient removal of the steam exhaust and frying odors.

Special precaution must be taken in designing an exhaust
canopy to avoid interference with the operation of the fryer.
Make certain the exhaust hood is designed high enough to allow
for proper opening of the fryer lid. We recommend you con-

sult a local ventilation or heating company to help in design­ing an adequate system.

The electric fryer is available from the factory wired for

2081120 or 240/120 volts, three phase 60 Hz. service. The power
cord may be already attached to the fryer, or provided at

installation. Check the data plate on the right side of the fryer

to determine the correct power supply.

This fryer must be adequately and safely grounded.

Refer to local electrical codes for correct grounding
procedures. If fryer is not adequately grounded,
electrical shock could result.

A separate disconnect switch with proper capacity fuses or

breakers must be installed at a convenient location between

the fryer and the power source. It should be an insulated copper
conductor rated for 600 volts and 90 “6. For runs longer than
50 feet, use the next, larger size wire.

Each Henny Penny pressure fryer was completely checked and
tested prior to shipment. However, it is good practice to check
the unit again after installation.

1. Cook a round of product.

2. Check to see that the indicator needle in the pressure
gauge is reading in the “Operating Zone”.

Should the pressure gauge read beyond the “Operating
Zone” turn the Power/Pump switch to the “OFF” posi­tion and refer to the Operation Control Valve Section.
Continued use of the unit at this high pressure could
result in serious injuries and severe burns.

3. Make sure lid gasket is not leaking, and no steam is coming
from safety relief valve.

4. Cheek the drain valve and fill line check valve

5. At the end of the cook cycle:

* The control will sound off by beeping.

The fryer will automatically depressurize.

6. Push the timer button.

7. When all the pressure has exhausted (observe pressure
gauge) open the lid.

DO NOT ATTEMPT TO OPEN LID UNTIL THE
PRESSURE DROPS TO ZERO. Opening the lid when
the cookpot is pressurized will allow hot shortening and
moisture to escape from the cookpot, resulting in severe
burns.

8. Let rack hang for 3-5 seconds, then proceed to take out
racks of chicken and place onto a bun pan.

If all the above functions have been performed satisfactorily

the fryer is ready for operation.

All operators, as well as maintenance and management
personnel, must throughly read and understand the
Operation Section prior to putting the fryer into opera­tion. Failure to adhere to these instructions could result
in serious bodily injury or property damage.

2-8. INTERNATIONAL

ELECTRICAL

~~REMENT~

Units being used outside the United States may not be shipped
with the power cord attached to the unit because of the
different wiring codes. The fryers are available from the
factory wired for 208240,380 and 415 volts, 3 phase, 50 Hertz

service. A terminal block is mounted inside the fryer for the

cable wiring. A decal on the inside of the right side panel will
help in the wiring of the unit.

To install the power cord, follow these procedures:

1. Remove the side panel from the right side of the unit.

2. Remove the front panel, behind the filter knob and quick
disconnect.

3. Thread the cable through the strain relief on the junction
box.

4. Attach the wires to the terminal block according to the
wiring diagram on the side panel.

5. Pull the slack out of the cable and tighten the screws on
the strain relief.

6. Pull the slack out of the cable and secure it with.the clamp
on the back of the cookpot.

Be sure the cable doesn’t sag, or it could interfere with
the use of the portable filter.

7. Pull the slack out of the cable and secure it with the clamp
on the frame, at the rear, right leg of fryer.

Be sure enough slack is out of the cable so it doesn’t
extend out past the portable filter stop bracket at the
bottom of the fryer frame. The cable could interfere
with the portable filter, not allowing it to be pushed
all the way in. This could cause hot shortening to spill
onto the floor.

8. Wiring the fryer is now complete.

3-1. OPERATING CONTROLS (Continued)

1. Cook/Pump Switch This is a three-way switch with center “OFF” position. Move
the switch to the position marked “POWER” to operate the
fryer. Move the switch to the position marked “PUMP” to
operate the filter pump. Certain conditions must be met prior
to operation of the filter pump. These conditions are covered

later in this section.

2. Cookpot This reservoir holds the cooking shortening, and is designed to

accommodate the Heat Exchanger, 8 head of product and an
adequate cold zone for collection of cracklings.

3. Cooking Rack This stainless steel rack consists of five baskets that contain

the food product during and after frying.

4. Lid Gasket The lid gasket provides the pressure seal for the cookpot

chamber.

5. Operating Valve The dead weight style operating pressure relief valve is used to

maintain a constant level of steam pressure within the cookpot.
Any excess steam pressure is vented through the exhaust stack.

NOTE

Remove the dead weight cap, and clean the cap, weight, and
orifice, once a day to prevent over pressurization of the
cookpot

6. Safety Relief Valve The safety relief valve is an ASME approved spring loaded

valve set at 14.5 psi (999 mbar). In the event the operation
valve becomes obstructed, this safety valve will release excess
pressure, keeping the cookpot chamber at 14.5 psi (999 mbar).
If this occurs, turn the Power/Pump switch to the “OFF”

position to release all pressure from the cookpot.

7. Safety Relief Valve Ring THE RING IS NOT TO BE PULLED.

Severe burns from the steam will result.

8. Gauge The pressure gauge indicates the pressure inside the cookpot.

3-4 201

9

Solenoid Valve

The solenoid valve is an electro-mechanical device that causes
pressure to be held in the cookpot.

The solenoid valve closes at the beginning of the frying cycle
and is opened automatically at the end of the frying cycle. If
this valve should become dirty or the teflon seat nicked,
pressure will not build up and it must be repaired per the
maintenance section.

Drain Valve

Drain Interlock
Switch

The drain valve is a two-way ball valve. It is normally in the
closed position. Pull the knob out to drain the shortening from
the cookpot into the filter drain pan.

DO NOT OPEN THE DRAIN VALVE WHILE
COOKPOT IS UNDER PRESSURE. Hot shortening
will exhaust from this valve. Severe burns will result.

The drain interlock switch is a microswitch that provides
protection for the cookpot in the event an operator inadver­tently drains the shortening from the cookpot while the main
switch is in the COOK position. The switch is designed to
automatically shut off the heat when the drain valve is opened.

Condensation
Drain Pan

The condensation drain pan is the collection point for the
condensation formed on the lid liner and within the steam
exhaust system. It must be removed and emptied periodically.

3-3. FILLING OR ADDING 1. It is recommended that a high quality frying shortening be
SHORTENING used in the pressure fryer. Some low-grade shortenings

have high moisture content and will cause foaming and
boiling over.

2. If a solid shortening is used, it can be melted into a liquid

level Indicator lines

first, then poured into the cookpot. Attempting to melt solid
shortening in the cookpot may cause burning or scorching
of the fresh shortening.

GLOVES SHOULD BE WORN AND CARE MUST
BE TAKEN WHEN POURING HOT SHORTENING.

Severe burns could result. Also, when adding fresh
shortening to existing shortening, care must be taken to
avoid splashing or severe burns could result.

3. The electric model requires 100 lbs. The pot has two level
indicator lines inscribed on the rear wall of the frypot
which show when the heated shortening is at the proper
level. Maintain hot shortening at the upper level indicator
line. Add fresh shortening as needed.

4. Cold shortening should be filled to 1/2 inch below lower
level indicator line.

3-8 203

Henny Penny Model 581

3-4. CARE OF THE
SHORTENING 1. To protect the shortening when the fryer is not in imme-

diate use, the fryer should be put into the Idle Mode.

2. Frying breaded products requires filtering to keep the
shortening clean. The shortening should be filtered at least
twice a day; after lunch rush and at the end of the day.

3. Maintain hot shortening at the upper level indicator line.
Add fresh shortening as needed.

The shortening level must always be above the heating
elements when the fryer is heating, and up to the upper
level indicator line on the frypot. Failure to follow these
instructions could result in a fire and/or damage to the
fryer.

With prolonged use, the flashpoint of shortening is
reduced. Discard shortening if it shows signs of excessive
smoking or foaming. Serious burns, personal injury, fire,
and/or property damage could result.

To avoid shortening overflowing the frypot, do not
overload the basket with product, or place product with
extreme moisture content into basket. The recommended
product load size is 22 lbs (9.9 kg.) Serious burns, personal
injury, fire and/or property damage could result.

203 3-9

The following procedures should be followed on the initial start­up of the fryer each time the fryer is brought from a cold, or
shut down, condition back into operation.

1. Check to see that all of the control switches are turned off.

2. Be sure the drain valve is CLOSED.

3. Remove carrier and baskets from lid and tilt lid back (see
section 3-2).

4. Fill the cookpot to a level at

l/2

inch below the bottom fill

line (see section 3-3).

5. Connect power to fryer.

6. Move the Cook/Pump switch to the “COOK” position.

7. Select the desired product using the Select Product switch.
The red indicator will be illuminated beside the product.

8. When the desired temperature has been reached the Ready
Light will illuminate. Stir the shortening at this time to
stabilize the temperature. Be sure to agitate the shorten­ing in the “cold zone”

in the bottom of the cookpot.

Do not stir the shortening at any other time except at
initial “cold” start-up. Failure to follow these instruc­tions can result in shortening overflowing the cookpot
which could cause serious burns, personal injury, fire,
and/or property damage.

9. After the shortening temperature has stabilized for a

minimum of 30 minutes, check the shortening temperature
using a good deep fat thermometer (Henny Penny part
number 12106). If off more than 5”F, refer to the
maintenance section.

10. If the shortening was not filtered the night before at shut­down, it should be filtered now, after the shortening
reaches the frying temperature (325°F) and before the
fryer is used.

If the shortening temperature exceeds 420°F imme­diately shut off the power at the main circuit breaker
and have the fryer repaired. If shortening
(temperature) exceeds its flashpoint, fire will occur,
resulting in severe burns and/or property damage.

11. Raise the lid up and place carrier and baskets onto lid.

12. Lower lid and emerse baskets into shortening, then raise
lid. This will keep the product from sticking to the baskets.
You are now ready to start frying.

Do not permit the fryer to set for an extended period

of time at high temperature (325 “F or above), because

the shortening will break down much sooner. When the
fryer is not being used for frying, put the controls to
the “IDLE” position.

1. Take the chicken parts, 2,4,6, or 8 cut-up chickens, from
the cooler and place in a scullery sink. Wash the chicken
and at this point break the thigh from the joint of the
backbone.

2. Remove any excess fat from the thigh.

I

3. Remove the chicken from the water and drain slightly but
allow the parts to remain moist.

4. If a breading machine is used, fill the breading drum with
approximately 8 to 10 pounds of PHT Fryer Mix. Feed
the moist but drained pieces into the chute at one end of
the breader.

5. Allow the breaded pieces to fall onto a tray as they come
out of the breader drum. (More breading may be needed
if a large amount of product is to be breaded.)

6. If a breading machine is not used, the food should be placed
in the dry mix and hand tumbled so that each piece of food

is completely covered.

7. Knock off any excess breading and place the breaded
product on a tray for cooler storage. Place a damp cloth

over the breaded food to retain moisture. The breaded food
should be held for a minimum of 30 minutes before fry­ing, so that it can absorb spices from the breading and

so that breading can better adhere to the product.

8. Prepare fryer as per start-up procedures.

9. Be sure the product selector is on chicken.

10. Lower the lid and baskets into shortening, then raise them
to grease the baskets.

11. Remove baskets and place product into baskets - the larger
pieces to the outside edge of baskets.

12. Place the baskets onto carrier, starting with the bottom
rack and working up.

13. Place cover grid on top rack to prevent pieces from
floating.

14. Lower lid and baskets and lock lid down.

15. Push the timer switch.

16. Within a few minutes, the pressure gauge should increase
to the operation zone. If it does not, recheck the procedures
and then refer to the troubleshooting section.

17. When the timer reaches zero the fryer will automatically
depressurize and the control will beep. Push the timer
switch to reset the controls.

Check the pressure gauge reading. Do not attempt to
open the lid until the pressure drops to zero. Opening
the lid when the cookpot is pressurized will allow hot
shortening and moisture to escape from the eookpot
resulting in severe burns to the operator.

18. After the pressure drops to zero, open the lid.

19. Let baskets hang for approximately 15 seconds before
removing the baskets.

20. Place the product into a warming cabinet immediately.

21. Before frying the next load, allow time for the shorten­ing to reheat. (Wait until the ready light comes on.)

Frying breaded food requires frequent filtering. Taste the cold

shortening every day for flavor. Watch the shortening for
foaming during frying cycles. Discard the shortening as soon
as it shows signs of foaming. Clean the frypot as follows each
time the shortening is changed or filtered.

1. Turn the power switch to the “OFF” position.

The best results are obtained when the shortening is
filtered at the normal frying temperature.

2. Remove carrier from lid of the fryer.

I

Rack may be hot. Burns could result.

3. Lower the lid to the lid stop bracket and tilt the lid back
and into an upright position (see section 3-2).

4. Use a metal spatula to scrape any build-up from the sides

of the frypot. Do not scrape heating element.

5. Roll the filter unit under the fryer, until the latch located

on the front, right leg of the fryer, secures the filter unit
in place.

The filter unit must be in the proper position beneath

the drain valve. This will prevent the splashing of
shortening on the floor. This splashing could result in
severe burns.

NING

6. Open the drain valve fully by pulling the drain valve knob
all the way out.

7. As the shortening drains from the cookpot, use brushes
(Henny Penny part number 12105 includes both brushes)
to scrape and clean the side of the cookpot and the heating
elements. If the drain fills with breading, use the white
brush to push the breading into the filter pan.

8. When all of the shortening has drained, scrape or brush
the sides and the bottom of the cookpot.

9. Rinse the frypot as follows:

A. Close the drain valve.

B. Connect hose of filter unit to the fryer.

C. Plug filter unit into the fryer.

Lower the lid so that the very first surge of shorten- Lower the lid so that the very first surge of shorten­ing will not splash up or over the top of the cookpot,
causing severe burns.

D. Turn the cook/pump switch to the “PUMP” position.

Carefully open lid to see if shortening is returning pro-

perly. Fill cookpot

l/3

full, then turn pump off.

If there are air bubbles coming up in the shortening,
it is possible that the filter connection union on the filter
tube line is not tightened properly. If so, turn off the
pump. Use gloves to tighten the union. Severe burns
could result.

E. Wash down and scrub the sides of cookpot. Use “L”

brush to clean the heating elements.

F. After the sides and bottom are cleaned, open the drain

valve and let shortening drain out, then close drain
valve.

10. Lower the lid down to the lid stop bracket during the first
surge of pumping and pump all the shortening out of the
filter pan and back into the frypot.

11. When the pump is pumping air only, the shortening in the
cookpot will appear to be boiling. Move the main power
switch to the “OFF” position.

When the appearance of boiling occurs, immediately
turn the pump off. This will prevent aeration of the

shortening, therefore increasing shortening life.

12. Check the level of the shortening in the eookpot. Add fresh
shortening if necessary, until it reaches the point between
the level indicators.

13. After completing the filtering operation, empty and
replace the condensation drain pan.

14. If frying is to be continued at this time, move the main
power switch back to the “COOK” position, and allow time
for reheating of the shortening.

The filter envelope should be changed after lo-12 filterings
or whenever it becomes clogged with crumbs. Proceed as

follows:

1. Unplug portable filter (PF-180) from cooker and roll filter
unit out from under the cooker.

2. Remove back cover from filter unit and remove crumb
basket. Discard crumbs and clean thoroughly with soap

and water. Rinse thoroughly with hot water.

3. Unscrew dairy union from standpipe and remove filter
head assembly from filter pan.

This union will be hot. Use protective glove or cloth,
or severe burns will result.

397

3-15

4. Lift the screen assembly from the drain pan.

5. Wipe the shortening and crumbs from the drain pan. Clean
the drain pan with soap and water. Thoroughly rinse with
hot water.

6. Unthread the suction standpipe from the screen assembly.

7. Remove filter clips and discard the filter envelope.

8. Clean the top and bottom filter screen with soap and

water. Rinse thoroughly with hot water.

Be sure that the filter screens, crumb catcher, filter
clips, and the suction standpipe are thoroughly dry
before assembly of filter envelope, as water will dissolve
the filter paper.

9. Assemble the top filter screen to the bottom filter screen.

10. Slide the screens into a clean filter envelope.

11. Fold the corners in, then double fold the open end.

12. Clamp the envelope in place with the two filter retaining
clips.

13. Place large washer on top of filter paper and screw on the
suction standpipe assembly.

14. Place complete filter screen assembly back into filter drain
pan.

15. Place filter assembly over suction standpipe assembly, and
connect filter union by hand. Do not use a wrench to
tighten.

16. Place crumb basket into position in the back of the filter
pan and place cover over it.

17. Portable filter is now ready to be slid under the cooker
for filtering.

The following steps will help prevent filter pump problems:

1. Make certain the filter paper envelope is properly installed
over the filter screens. Make sure the open end of the
envelope is properly folded over and clamped in place with
the retaining clips, so that the envelope is sealed and
crumbs cannot enter.

2. Make sure the filter valve is kept closed at all times during
frying.

3. Make sure all the shortening has been pumped from the
filter lines and the pump by allowing the filter pump motor
to run until the shortening in the cookpot appears to be
bubbling or boiling.

The filter motor is equipped with a manual reset button in the
event the motor’s thermal protector actuates. This reset button
is located on the front of the filter head assembly, behind a

hinged circular door. Wait approximately 5 minutes before

attempting to reset this protector device.

Use steady, hard pressure on the reset button until a

definite “click” is heard. The button takes some force

to reset.

To prevent burns caused by splashing shortening, the
unit’s power cord must be unplugged before resetting
the filter pump motor’s manual reset protection device.

After the initial installation of the fryer, as well as before every
change of shortening, the cookpot should be thoroughly cleaned
as follows:

1. Turn the main power switch OFF.

The filter drain pan must be in position under the drain
valve to prevent splashing or spilling of hot liquids.

Failure to do so will result in splashing and severe

burns.

2. If hot shortening is present in the cookpot, it must be
drained by slowly pulling the drain valve knob.

3. Close the drain valve. Discard the shortening in the filter
pan. Roll the empty filter pan under the fryer.

4. Lower the lid to the lid stop bracket and tilt lid back, so
that the lid won’t interfere with cleaning.

5. Fill the cookpot to the level indicators with hot water. Add

8 to 10 ounces of fryer cleaner (Henny Penny part number

12101) to the water and mix thoroughly.

Always wear safety goggles or face shield and protec­tive rubber gloves when cleaning the cookpot, as the
cleaning solution is highly alkaline. Avoid splashing or

other contact of the solution with eyes or skin. Severe
burns or blindness could result. Carefully read the
instructions on the cleaner. If solution comes in con­tact with eyes, rinse thoroughly with cool water and
see a physician immediately.

6. Enter Boil Out mode. (See page 6-8.)

NEVER PRESSURIZE FRYER TO CLEAN. Leave
lid open. Water under pressure is super heated and will
cause severe burns if it comes in contact with skin.

Henny Penny Model 581

3-11. CLEANING THE FRYPOT

(Continued)

DO NOT let the cleaning solution boil. If the cleaning
solution in the cookpot starts to foam and boil over, DO
NOT TRY TO CONTAIN IT BY CLOSING THE
FRYER LID or severe burns could result.

7. Using the fryer brush (Henny Penny part number 12105)
scrub the inside of the cookpot, the lid liner, and around
the counter-top of the fryer.

Do not use steel wool, other abrasive cleaners or clean­ers/sanitizers containing chlorine, bromine, iodine or
ammonia chemicals, as these will deteriorate the
stainless steel material and shorten the life of the unit.

Do not spray the unit with water, such as, with a garden
hose. Failure to follow this caution could cause component
failure.

8. After cleaning, turn off the main power switch. Open
the drain valve and drain the cleaning solution from the
cookpot into the drain pan and discard.

9. Close the drain valve and refill the cookpot with hot
water to proper level.

10. Add approximately 16 ounces of distilled vinegar and
heat the solution to no more than 195ºF (91ºC).

11. Using a clean brush, scrub the interior of the cookpot and
lid liner. This will neutralize the alkaline left by the
cleaning compound.

12. Drain the vinegar rinse water and discard.

13. Rinse down the cookpot, using clean hot water.

14. Thoroughly dry the drain pan, and the cookpot interior.

NOTE

Make sure the inside of the cookpot, the drain valve
opening, and all parts that come in contact with the
new shortening are as dry as possible.

This high temperature control is a manual reset control which
senses the temperature of the shortening. If the shortening
temperature exceeds 420 “F (215 “C), this control switch will
onen and shut off the heat to the cooknot. When the
temperature of the shortening drops to a safe-operation limit,
the control must be manually reset. The reset button is located
above the filter knob in the front of the cooker. This will allow
heat to be supplied to the cookpot.

Before replacing a high temperature limit control, check to

see that its circuit is closed.

The shortening temperature must be below 380°F
(193°C) to accurately perform this check.

The electric fryer requires two switching co&actors:
contactor and a heat contactor. The primary contactor
energizes (contacts close) any time the Cook/Pump Switch

is in the “COOK” position and the temperature of the pot is

below 420°F (215°C). The high limit will cut the power at the

primary contactor if temperatures in the cookpot exceed 420 “F
(215°C). The primary contactor supplies power to one side of
the heat eontactors.

The heat contactor (mercury contactor) is controlled by the
computer controller. When the controller calls for heat, the
heat contactor applies power to one side of the heating

elements. When the heat contactor and the primary eontac­tor are energized (contacts closed), the electric heating
elements heat the shortening.

The following checks are performed with the wall cir-

cuit breaker on, and the Cook/Pump Switch in the
“COOK” position. Extreme caution should be taken.
Make connections before applying power, take reading,
and remove power by unplugging the power cord, or

by turning off the wall circuit breaker, before remov-

ing meter leads or electrical shock could result.

5. With power re-applied and in a heat-up mode, check the
power going to both contactor coils. This is to be sure
power is going to the contactors.

If no voltage is found going into the coils, check wiring, high-

limit, and drain switch for the primary contactor. (See

Maintenance Section). For the heat contactor, check wiring
and connection at the P.C. Board.

If either contactor is defective it must be replaced as follows:

Remove electrical power supplied to the fryer by
unplugging power cord or turning off the wall circuit
breaker, or electrical shock could result.

1. Remove only those wires directly connected to the con­tactor being replaced. Label the wires.

2. Remove the two mounting nuts on the base plate and
remove standard contactor (primary), proceed to step 5,
if this is the contactor to be replaced.

3. Remove the two mounting nuts securing the mercury con­tactor bracket to the base plate and remove bracket.

4. Remove the two screws securing the mercury contactor

to the bracket and remove contactor.

5. Install new contactor in reverse order of previous steps.

Each electric fryer uses two heating elements.

Heating elements are available for 208 or 220/240,380
and 415 voltage. Check the data plate on the right side
panel of unit to determine the correct voltage.

If the shortening’s temperature recovery is very slow, or at

a slower rate than required, this may indicate defective heating

element(s). A multimeter will quickly indicate if the elements
are shorted or open.

Henny Penny Model 581

PRESSURE REGULATION The Henny Penny Fryer uses pressure as one of the co

ponents of the cooking process. Once the lid is sealed to
the cookpot, and the solenoid valve closes, a deadweight
valve maintains the correct pressure in the cookpot.

The lid has minimal and limited maintenance and repair
procedures, which are addressed in the following sections.

The following is a routine maintenance schedule for the Lid:

Every 90 days

• Clean and reverse lid gasket

Yearly Cleaning and Inspection

• Remove and clean Safety Relief Valve

• Check Lid Gasket for splitting and tears - replace if

necessary

-

• Check Pressure Pads for wear - rotate if necessary

• Check Cam Slide Guides - replace if worn or broken

• Check Lid Rollers - replace if cracked or damaged.

5-19. REVERSING THE LID The gray rubber gasket surrounding the inside of the lid is

designed to be reversed. HENNY PENNY RECOMMENDS
THAT THIS BE DONE EVERY 90 DAYS.

Because of heat expansion and the pressure used for the
cooking process, the gasket is constantly under extreme stress.
Reversing the lid gasket every 90 days helps to assure that the
fryer will not lose pressure through leakage.

1. Put the lid in the upright position, as previously described
in section 3-2.

2. Using a thin blade screwdriver pry out the gasket at the
corners. Remove the gasket.

Be careful that the lid doesn’t fall down while it is in the
upright position, or serious injury could result.

3. Clean gasket and the gasket seat with soap and hot water.

4. Rotate gasket with the opposite side facing out.

1005 5-19

Begin the installation by installing the four corners of
the lid gasket, and smoothing the gasket into place from
the corners.

The Lid Counterweight in the back of the fryer balances the
weight of the lid system to allow easier opening and closing
of the lid. The weight has two cables attached to it, and weighs
about 150 lbs. (67.5 Kg). One cable is centered on the weight

and is the cable being used. The other cable is a safety cable
and is off center. In case the main cable becomes loose or
broken, the safety cable catches the weight and puts the weight
into a bind, not allowing the lid to be opened or closed.

1. Using a 3/8” socket, remove the back shroud of the fryer.

2. With one person holding the weight level, another person
locks the lid down.

3. Unthread the broken cable from the weight and the
bracket attached to the fryer, and remove broken cable.

4. Thread a 5/16” nut on each end of the new cable.

5. Screw the new cable into the weight, using a wrench, until
it is tight.

6. Using a l/2” wrench, tighten the nut (already threaded
on the cable) against the weight securing the cable into

the weight.

Henny Penny Model 581

5-20. LID COUNTERWEIGHT 7. Pull cable over pulley and down behind the weight.

(Continued)

8. Thread the other end of the cable through a 5/16” nut on
the underside of the bracket.

9. Tighten the cable up by screwing the cable through the
nut, until the weight becomes level.

NOTE

The safety cable should now have some slack in it, with
the weight level. (See photo at left).

10. Tighten the nut against the bracket, securing the cable.

11. Replace the back shroud. Repair is now complete.

5-21. PRESSURE PADS The Pressure Pads are plastic strips that the lid cam presses

against to seal the lid. They are located under the lid cover
and under the lid cam.

Removal

1. Raise the lid.

2. Remove the four screws securing the lid cover and
remove cover.

3. Push the lid cam back, off of the pressure pads.

4. Using a 5/32” hex drive, remove the bolt securing the
pressure pad and remove broken pad.

5. Install new pad in reverse order.

NOTE

If one side of the pressure pad is worn or broken, the
pad can be turned 180º and the opposite end of the
pressure pad used. Remove the bolt and turn the pad
end for end.

1201 5-21

Henny Penny Model 581

5-22. LID ADJUSTMENT If steam leaks out from around the lid gasket, the pressure pads

could be worn or broken. If the pressure pad is worn, but not
broken, it can be reversed 180 degrees, and the other end of the
pad used. See Section 5-12.

Other problems could cause the steam to leak, such as a

cracked or worn gasket, or gasket not installed properly.

Be certain leaking is not caused by too much pressure
before making any lid adjustments. Fryer should be
operating at 12 psi. Refer to Operating Control Valve
section. All these areas should be checked, or serious burns
could result.

5-22 5-22

With the carrier and racks installed on the lid, the lid should

stay down, in contact with the pot rim, when the lid is lowered.
The user will then be able to lock the lid in place. If the lid

has a tendency to rise up before getting the lid locked down,

the magnet plate probably needs adjusting. Follow these steps:

1. Remove the six nuts securing the back shroud and remove
back shroud.

2. Loosen the bottom nut under the plate and unscrew both
nuts a couple turns, then lower the lid again to see if the
lid stays down. If not, repeat procedure.

3. Tighten lower nut up against the other nut and install back

shroud - adjustment is now complete.

This is an electromechanical device that causes pressure to be
held in the cookpot. The solenoid valve closes at the beginn­ing of the cook cycle and opens automatically at the end of
the cook cycle. If this valve should become dirty, or the Teflon
seat is nicked, pressure will not build up. The electric fryer
uses a 208/240 volt, 60 hertz coil (50 hertz internationally).

Before starting repair procedures, move the
Cook/Pump switch to the “OFF” position. Disconnect
main circuit breaker at the circuit breaker box and/or
unplug service cord from the wall receptacle or elec­trical shock could result.

Remove the solenoid wires from the wire nuts which are found
behind the control panel. Check across wires.

other injuries could result.

The operating valves are located at the back of the unit. The
valve left of the pressure gauge is a 14-½ lb. safety relief valve,
and to the right of the pressure gauge, the operating valve.

Valves are working properly, when “OPERATING ZONE”
indicates on the gauge by the pointer. The gauge pointer
should not normally exceed the operating zone. If the pressure
builds to 14 ½ lbs., the safety relief valve opens and releases
pressure from the frypot

This section provides programming procedures for the 581
Fryer. The operational controls should be read and understood
to become familiar with the control and its functions. If
technical assistance is needed, refer to the toll free number

printed in this manual.

It is recommended to fill out the program worksheet
that was shipped with the unit before programming.
This will result in less confusion when programming
the control.

1. Move the keyswitch to the PROGRAM position.

2. Depress the SELECT PRODUCT switch to the desired
product. The red indicator light will illuminate beside the
particular product you are programming.

3. By depressing the SELECT FUNCTION switch, you pick
the function to program such as time, temperature, etc.
The function you are in will be flashing. Program TIME
first.

4. Depress the change switches beneath the digital display
until the desired time is displayed. Example: 11 minutes

- ll:oo.

5. Continue this procedure until you have programmed
TIME, TEMPERATURE, ALARM, and PRESSURE.

An alarm cannot be programmed on the first interval
of any product. Also, when programming temperature,

the display will read any temperature between 170 o to

390°F. Below 170°F the display will read LO. Above
390°F the display will read HI.

6. By depressing the SELECT TIME switch you can change

intervals within that function. You may program up to 10
intervals per function.

7. Load compensation, load anticipation, proportional con­trol, and filter cycle can only be programmed in interval
one. When changing to interval two, only time,
temperature, alarm, and pressure will illuminate in the
function display.

Load compensation, although factory preset, is programmable.
Load compensation adjusts cooking times to compensate for
differences in the cooking process such as load size. The control

is continuously comparing the pot temperature to the setpoint

temperature. If the pot temperature is above the setpoint, then
the control will shorten the cook time. If the pot temperature
is below the setpoint, then the control will lengthen the cook
time. This is programmable within this function by display­ing 0 to 10. Zero meaning no load compensation, while ten
means the highest load compensation.

When dropping a large load of product into the fryer, there
is a large temperature drop. On normal controls there is a time
period before the thermostat senses this drop. With load
anticipation this time period is avoided by turning the heat

on as soon as the timer is activated. The heat will remain on
until the control senses that the temperature is increasing at
which point normal heat control takes over. When program­ming, the display will read 0” to 10°F. For example: if 5
degrees is programmed, this means the temperature cannot

exceed five degrees above setpoint temperature before normal
heat control takes over. This is a safeguard or a temperature
limit.

Proportional control regulates pot temperature by pulsing the

heat until it reaches setpoint temperature. This allows tighter
regulation of pot temperature. The control can be programmed

0 to 30 degrees; zero being no proportional control (best
recovery time) and up to thirty degrees meaning the control
will pulse the heat off and on thirty degrees before it reaches
setpoint (best temperature regulation). Since each product can

be programmed with a different proportional control factor,

temperature accuracy and recovery time can be tailored to each

food product.

The filter cycle count is a method of keeping track of when
it is time to filter the shortening. To determine when it is time
to filter, the control adds the (fractional) number of the cycle
count to a running total at the end of each cook cycle. When
this total exceeds one, then the “FIL” (“FIL” within the digital
display) indication is given.

An example of this would be as follows:

=
=
=
=

Cycle

l/4
l/3
l/2
l/2

Pro

roduct

Chicken
Fish
Potatoes
Vegetables

If the operator cooked one cycle of chicken, one cycle of fish,
and one cycle of potatoes, the unit would indicate to filter since
l/4 + l/3 + l/2 = 1 l/2 which is greater than one. In the event

the unit cannot be filtered at the proper time the filter program

mode may be bypassed. Turn the power switch to OFF for at

least 5 seconds, then turn the unit back to the COOK position.

Filter will be bypassed and unit will return to programmed
1st cycle.

The idle mode’s main function is to lessen the breakdown of
shortening, by programming a lower temperature, when the
unit is not in use. The idle mode can be selected by depressing
the SELECT PRODUCT switch until the idle mode is
indicated. Automatic idle is enabled by programming “A” in

the display. Also, the idle time can be programmed. This means
the control will select idle automatically after the programmed
time has elapsed.

If automatic is not programmed, idle must be selected
manually. Idle time is programmed from 0 to 255
minutes.

When this is programmed the type of idle can be selected:
idle or time idle. This is indicated by a “6” or “T”. In cycle
idle the programmed time is started evey time a new product
is selected. In timer idle the programmed time is started at
the end of each cook cycle. Depress the SELECT FUNCTION
switch. A “6” or “T” will be displayed indicating cycle idle
or time idle. Also, the idle temperature can be programmed
from 170 “F to 390°F. This is normally set at 250°F.

cycle

The following are four examples of the idle mode.

Example 1: AUTOMATIC IDLE - idle temperature is 250°F

the idle time is 30 minutes. Control is programmed in cycle

If no product is cooked within 30 minutes, control will

atically select IDLE and regulate at 250°F.

Example 2: AUTOMATIC IDLE - idle temperature is 250 “F
and the idle time is 30 minutes. Control is programmed in cycle

e. Several loads of different products are Cooke
as no more than 30 minutes pass between product selections,
the control will not select idle.

Example 3: AUTOMATIC IDLE - idle temperature is 250°F
and the idle time is 30 minutes. Control is programmed in timer
idle. A product is selected and several loads are cooked. As
long as a load is cooked within 30 minutes of the last load, the
control will not go into idle. If 30 minutes pass between loads,
the control will automatically select idle.

Example 4: AUTOMATIC IDLE IS NOT PROGRAMMED ­control in manual idle. The control will remain in the product
selected by the operator. Operator must use SELECT
PRODUCT switch to enter idle mode.

The melt mode is used to safely melt solid shortening and can
also be used with liquid shortening. Gradually heating or
melting the shortening greatly extends its life. This is
automatically accomplished in the melt mode by turning the
heat on for 3 seconds and off for 27 seconds. The operator has
the option of entering melt manually with the SELECT
PRODUCT switch or programming automatic melt. Select the
melt mode and program “A” for automatic. At this time also

program the melt temperature. This is the temperature the

control will exit the melt mode and go into the heat mode. It
is recommended to program this temperature at 170°F. After
programming, the control will work as follows:
is turned on the control checks the pot temperature. If the pot
temperature is below 170 “F or programmed temperature, the

unit will enter the melt mode. If the pot temperature is above

170°F or programmed temperature, the unit will enter the

programmed 1st cycle.

Once pot temperature exceeds the programmed melt
temperature the melt mode cannot be entered.

when the unit

While in the melt mode, the first cycle can also be programmed.
This is the cycle the control will automatically select when in
COOK upon exiting the melt mode. It is programmed by select­ing the melt mode and depressing the SELECT FUNCTION
switch. The green 1st cycle light will flash and the temperatture
light in the function display will be on. The left half of the
product display are numbered from top to bottom, 1 to 6. The
right half are numbered 7 to 10. Melt and Idle are not
numbered. However, idle can be selected as the first cycle. If
number one of the product display is desired as the first cycle,
program a number one, If number eight of the product display
is desired, program number eight.

An unprogrammed product cycle cannot be selected as
the first cycle.

The one button programming feature is a simple way for the
operator to place Henny Penny’s cooking parameters into the
control’s memory. These programmed cooking cycles are
matched with the menu item cards sent with each unit. To
achieve this one button programming, follow these steps:

1. Turn the COOK/PROGRAM keyswitch to the PROGRAM
position.

2. Depress the TIMER switch. This will put you into the
Special Program Mode. The display will read “SP”.

3. Using the SELECT PRODUCT switch, select the number
7 product (this will be the top right menu item).

4. Under the digital display there are four switches. Depress

t.

the see switch from the ri

The display will show
“INIT” briefly and then show “HP” for approximately
2 seconds. The control will then automatically exit the
Special Program Mode and enter the Normal Program

Mode. All of Henny Penny’s cooking parameters are not
in the control’s memory.

This feature will aid the operator in the event there is a power
outage. If the control is timing down and the power supply
is interrupted for any reason, the control will not reset to the
original cook cycle time. When power is restored, the control
will resume timing at the point the power was interrupted,
allowing the operator to know what time is needed to finish
cooking that particular load of product.

6-12. CLEAN-OUT MODE The unit has a clean-out mode, which is factory pre-

programmed. To enter the clean-out mode, follow the
instructions below:

1. Place the keyswitch in the COOK position.

2. Press the SELECT PRODUCT button and select either
IDLE or MELT.

3. Press the TIMER button.

4. Display reads “Y” for yes, and “N” for no.

5. If you desire the clean-out mode, press the button below the
“Y”. Fryer heats to factory pre-programmed clean-out
temperature.

6. If, for any reason, you don’t wish to enter the clean-out
mode, depress the button below “N”.

7. After clean-out is complete, turn power switch to OFF and
drain contents from fryer.

NEVER PRESSURIZE FRYER TO CLEAN. Leave lid
open! Water under pressure is super heated and causes
severe burns if contacts skin.
