The Henny Penny Pressure Fryer Model 520 is a basic unit
of food processing equipment. It has found wide application
in institutional and commercial food service operations.
A combination of Pressure, Heat, and Time is automatically
controlled to produce the optimum in a tasty, appealing
product.
Pressure is basic to this method of food preparation. The
pressure 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, the 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.
eat
e
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 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.
As in any unit of food service equipment, the Henny Penny
Pressure Fryer Model 520 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.
@ Easy to use timer and thermostat controls set in recessed
panel to protect from spills.
Pump switch for optional built-in automatic filter system.
Easy access to drain valve and filter valve handles for
manual filtering.

7Safety Relief V alveThe safety relief valve is set at 14.5 PSI (99.9 KPa). In the
event that the dead weight valve becomes clogged, the safety
valve releases excessive pressure, keeping the frypot at a
maximum of 14.5 PSI (99.9 KPa). If this occurs, turn the main
power switch to the OFF position to release all pressure from
the frypot. Also, clean the dead weight valve at this time.
DO NOT pull the Safety Relief Valve Ring, or severe burns
will result.
8Pressure GaugeIndicates nominal pressure within the frypot. This gauge is not
used to calibrate the dead weight assembly . Operating pressure
of the dead weight assembly is preset at the factory .The gauge
is used as an indication of pressure build up within the frypot.
9Solenoid V alveAn electromechanical device that causes pressure to be held in

High Temperature
Control
Lid/Locking Assembly
Fun~tio~
The high temperature thermostat is a manual reset control
which senses the temperature of the shortening. If the shorten-
ing temperature exceeds the safe operating limit, this control
will remove power from the contactors, thus removing heat
to the cook pot. When the temperature of the shortening drops
to preset safe operating limit, the control must be manually
reset. The reset button is located on the upper surface of the
recess in the front panel below the regulating thermostat.
Before pressure will build in the cook pot, the lid must be closed
and locked. To close the lid, push the lid down with one hand
by using the plastic handle on top of the lid. While holding the
lid closed with one hand,. turn the handle on the latch
counterclockwise 160 o (until it contacts the stop) to lock the lid.
DO NOT place your free hand on top of the lid during
the latching procedure. The surface may be hot and
burns could result.
15
Condensate Drain Pan
The lid will not latch or pressure build unless the handle is fully
latched. As pressure builds within the cook pot, the handle will
be locked in place. As long as the locking assembly is engaged,
it will prevent the handle from being moved clockwise and
opening the lid. The locking assembly disengages when the
internal pressure falls below 1 PSI (6.8 KPa).
The condensate drain pan is located behind the panel, below
the drain and filter valve handles. Remove the panel and the
condensate pan is located on the left. It can be easily removed
by grasping the handle and pulling out carefully. The condensation pan should be emptied daily.

The first step in the use of the Henny Penny Model 520 is to
learn the controls. Next, determine the time and temperature
settings. The following will assist you in determining these
settings but are approximate and will vary with the size and
quantity of the raw product.
The following procedures should be followed in the initial
start-up of the fryer and each time the fryer is brought from
a cold or shut down condition back into operation.
1. Check to see that all control switches are turned OFF.
2. Be sure that the drain valve and filter valve are closed.
3. Remove the wire basket from the cook pot and leave the
lid open.
4. Fill the cook pot with shortening to level indicated. The
level indication is the maximum shortening level when hot.
5. Connect the power to the fryer.
6. Move the main power switch to the COOK position.
7. Turn the thermostat knob to the desired cooking
temperature. The temperature light will go on.
8. When the shortening has reached the desired cook
temperature, the temperature indicating light will be off.
9. Thoroughly stir the shortening to stabilize’the temperature
throughout. Make sure that the shortening at the bottom
of the pot is agitated and evenly heated.
10. 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
no. 121006).
11. Lower the empty basket into the cook pot (food will be
added later).
12. Select the desired cooking time. You are ready to start
cooking.
NOTE: The overall operation of the 520 Fryer is no
different than our present Model 500 or Model
600 Pressure Fryers.
1. It is recommended that a high quality liquid frying shortening be used in the pressure fryer. Some low grade shortenings have a high moisture content and will cause foaming
and boiling over.
2. If a solid shortening is used, it must be melted to a liquid
first, then poured into the frypot. Attempting to melt a
shortening in the frypot may cause burning or scorching
of the fresh shortening.

Gloves should be worn and care must be taken when
pouring hot shortening into the unit. Severe burns could
result. Also, when adding fresh shortening to existing
shortening, care must be taken to avoid splashing.
3. Cold shortening should be filled approximately 112 inch
below the bottom level of the level indicator line. The
shortening will expand when heated.
3-5. COOKING
1. Before dropping the product into the basket, make certain
that the shortening is at the correct cooking temperature
for the type of product. Also, check that the temperature
light is OFF. Once the product has been prepared, you are
ready to cook. Place the basket in the cook pot a few
seconds before placing the product in the basket.
2. Place the product into the submerged basket by first
dropping in the larger pieces. This gives the larger and
more difficult pieces a few .extra seconds to cook in the
shortening. Continue to place the remaining product in
the basket.
3. Lift the basket slightly out of the shortening and shake
it, causing the pieces to separate. Return the basket to
the shortening. Doing this will prevent white spots on the
finished product.
4. Remove the basket handle and close the lid quickly. Latch
the lid as previously described.
5. Activate the time as previously described. Within a few
minutes, the pressure gauge will increase to the operating
zone.
6. At the end of the cooking cycle, the fryer will automatically
depressurize. Also the timer light will go off and the timer
will automatically reset.
7. After the pressure drops to 0, open the lid latch assembly
by turning the handle clockwise 160 O.
Henny Penny Model 520
3-5. COOKING PROCEDURES8. Raise the lid promptly to allow most of the condensation
(Continued)on the lid to drain down and out through the drain channel.
Do not let the lid slam up against the back stop. This could
damage the hinge assembly . This will also allow condensation to
drop back into the shortening.
NOTE: The condensation opening behind the pot needs to be
kept clear of obstructions. Failure to do so will cause the
moisture to back up onto the countertop.
9. Insert the handle into the basket, lift the basket out of the
shortening, and hang it on the side of the cook pot to drain.
Allow the product to drain approximately 15 seconds before
placing it into the tray .
10. The fryer will automatically recover to the preset cooking
temperature. Once the thermostat indicator light goes out, you
can begin the next cook cycle. If filtering of shortening is
desired at this time, refer to the next section.
NOTE: When no additional cooking is intended within 30 minutes
of the previous cook cycle, it is recommended to reduce
the shortening temperature (by turning the thermostat
knob counterclockwise) to 275
o
F (135o C).
Four product controls, use the “C” (up and down)
buttons and select Idle. The controls will automatically
o
reduce the temperature to 250
F (121o C).
3-6. FIL TERING THECooking breaded products requires frequent filtering to keepSHORTENINGthe shortening clean. The shortening should be filtered after
every three to six cooking cycles. For the best quality product, do
not exceed six cook cycles without filtering.
1. Turn the thermostat and the main power switch to the OFF
position. Remove and clean the fry basket in soap and water .
Rinse thoroughly .
NOTE: For best results, filter shortening at normal cooking
temperature.
2. Use a metal spatula to scrape build up from sides of the frypot.
When using the pot scraper, do not damage the capillary line on
the thermostat, or the high limit control. Also, do not scrape the
heating elements, or damage to elements could result.

The filter pan must be in the
the drain valve. This will prevent the splashing of the
hot shortening as it drains into the filter drain pan
which would cause burns.
3. Open the drain valve by pulling it forward slowly. This
will prevent excessive splashing of the hot shortening as
it drains into the filter drain pan.
4. As the shortening drains from the fry pot, use bushes
(Henny Penny part no. 12105) to scrape and clean the sides
of the fry pot and the heating elements. If the drain fills
with breading, use the white brush to push the breading
into the filter pan.
5. When all of the shortening has drained, scrape or brush
the sides and the bottom of the cook pot.
6. Rinse the cook pot as follows:
A. Close the drain valve by pushing the handle inward.
B. Open the filter valve by turning the handle counter-
clockwise.

Hold the lid closed so that the very first surge of the
shortening will not splash up or over the top of the cook
pot’. Severe burns will result.
C. Move the main power switch to the PUMP position.
Carefully open the lid to see if shortening is returning properly. Fill cook pot l/3 full, then turn off the
mum. . .
If there are air bubbles coming up in the shortening,
it is possible that the filter connecting union on the filter
tube line is not tightened properly. If so, turn off the
pump and use gloves to tighten the union. *This union
will be hot and severe burns will result.

D. Wash down and scrub the sides of the cook pot. Use
“L” brush to clean the heating elements.
E . After the sides and bottom are cleaned, open the drain
valve.
7. Pump all the shortening out of the filter pan and back into
the cook pot. Close the lid during the first surge of
pumping.
8. When the pump is pumping air only, the shortening in the
fry pot will appear to be boiling. Close the filter valve first
and then move the main power switch from PUMP to
OFF. This will keep the filter pump and lines from filling
up with shortening.
Note: When the appearance of boiling occurs, immediately
close the filter valve, then turn the pump off. This will
prevent aeration of the shortening, therefore increasing
shortening life.
9. Check the level of the shortening in the cook pot. Add fresh
shortening, if necessary, until it reaches the level indicator
line on the rear wall of the cook pot.

Place power switch in the OFF position, shut off power
at the fuse or breaker box. Failure to do so could result
in electrical shock.
Whenever the thermostat fails to maintain the selected
temperature within f 5 “F (- 15 “C) of the thermostat setting,
it should be calibrated.
To calibrate the thermostat, it is necessary to perform step
increases in the temperature of shortening. Follow this
procedure:
1. Place the main power switch in the POWER position. Be
sure there is shortening in the frypot.
2. Set the thermostat knob to 250°F (121” C).
3. Allow enough time for the shortening to heat. When the
shortening reaches the set temperature on the thermostat,
the indicator light will go off. Usually, it will take no longer
than 15 minutes for the shortening to heat to the set
temperature.
4. Remove the fry basket from the shortening.
5. Stir the shortening with the basket handle.
6. Measure the temperature of the shortening using an
accurate, mercury tube type, deep fat thermometer
capable of measuring temperatures in the 250 “F to 400 “F
(121 “C to 204°C) range. (Henny Penny part number
12106.)
7. Insert the thermometer near the center of the frypot to
a depth of about 3 inches below the level of shortening.
8. Carefully stir the shortening with the thermometer.
9. Allow the mercury in the thermometer to rise to the
temperature of the shortening. Hold the thermometer
straight up and down.
The temperature reading is to be taken just as the
TEMP indicator light goes off. This will give the correct
temperature rather than an override temperature.
10. If the temperature is within 5°F (- 15°C) of the
temperature set on the thermostat, increase the thermostat setting approximately 25 “F (- 4°C). Wait until the
indicator light goes off, then again check the temperature
el 520
of the shortening. If it is again within 5 “F (- 15%), the
thermostat does not require calibration.
If the thermometer is accidentally broken, and mercury
and pieces of broken glass fall into the shortening,
discard the shortening and clean the frypot thoroughly.
Mercury is highly poisonous.
11. If the temperature indicated on the thermometer differs
more than 5 “F (- 15 “C), remove the thermostat knob by
pulling it off its stem.
Do not rotate the knob while removing it.
12. Turn the adjustment screw in the center of the hollow
stem, using a small blade screwdriver. If the thermometer
reading was higher than the setting, rotate the screw
clockwise. If lower, counter-clockwise. For example:
setting:
reading:
adjustment:
After adjusting the screw, install the knob and reset the
13.
thermostat to 250°F (121 “C). Again, measure the
temperature of the shortening with the deep fat thermometer. Wait a few moments for the shortening to reach
the 250 “F (121 “C) temperature setting, indicated on the
thermometer. The indicator light should go off when the
temperature reaches 250 “F (121 “C). Readjust screw if
necessary.
15. Check the temperature of the shortening when the
indicator light goes off.
16. If the temperature measured on the thermometer is not
within 5 “F (- 15 “C) of the thermometer setting, adjust
for the correct temperature as in steps 12 and 13 of this
procedure.
Once the thermostat has been calibrated and set at the
desired cooking temperature, do not use the thermostat
to turn the fryer ‘off. Use the ON-OFF switch.
This high temperature control is a manual reset control
which senses the temperature of the shortening. If the
shortening temperature exceeds the safe operating
limit, this control switch will open and shut off the heat
to the frypot. When the temperature of the shortening drops to the safe operating limit, the control must
manually be reset.
Before replacing a high temperature limit control, check to
see that its circuit is closed.
The shortening temperature must be below 330°F
(192°C) to accurately perform this check.
1. Remove electrical power supplied to the fryer.
Place POWER/OFF/PUMP switch in the OFF
position, and unplug the power cord or open the wall
circuit breaker, or electrical shock could result.
2. Remove the control panel.
3. Remove the two electrical wires from the high
temperature limit control.
4. Check for continuity between the two terminals after
resetting the control. If the circuit is open, replace the
control, then continue with this procedure. (If the circuit
is closed, the high limit is not defective. Reconnect the two
electrical wires.)
Before following these steps,
POWER/OFF/P~P switch in the OFF position, and
unplug the power cord or open the wall circuit breaker,
or electrical shock could result.

1. If the tube is broke&i or cracked, the control will open,
shutting off electrical power. The control cannot be reset.
2. Drain shortening from the frypot.
3. Remove control panel.
4. Loosen small inside screw nut on capillary tube.
5. Remove capillary bulb from bulb holder inside the fry-pot.
6. Straighten the capillary tube.

7. Remove larger outside nut that threads into pot wall.
8. Remove the two screws that secure the high limit to the
high limit bracket.
9. Remove defective control from control panel area.
10. Insert new control and replace screws.
11. Uncoil capillary line, starting at capillary tube, and insert
through frypot wall.
To avoid electrical shock or other injury, the capillary
line must run under and away from all electrical power
wires and terminals. The tube must never be in such
a position where it could accidentally touch the
electrical power terminals.
Step 3
Place power switch in the OFF position, shut off power
at the fuse or breaker box. Failure to do so could result
in electrical shock.
1. Drain the shortening.

ASSEMBLY
Do not attempt to remove the valve cap while the fryer is in
operation, or severe burns or other injuries could result.
The deadweight valves are located behind the lid. The valve, left of
th e pressure gauge, is a 14 1/2 lb. (999 mbar) safety relief valve, and
the one on the right is the operating valve.
V alves are working properly , when the pointer on the gauge is in the
Deadweight Valve“OPERA TING ZONE” (green area). The gauge pointer should
not normally exceed the operating zone. If the pressure builds to
14-1/2 lbs.(999 mbar), the safety relief valve will open to release
steam pressure from inside cookpot.
CAPORIFICEWEIGHT
DO NOT MANUALL Y ACTIVA TE THE SAFETY
RELIEF VAL VE. Hot steam will be released from valve
when ring is pulled. Keep away from safety valve exhaust,
or severe burns could result.
1. A T THE END OF EACH DAY’S USAGE OF THE
FR YER, THE OPERA TING VAL VE MUST BE
CLEANED. The fryer must be OFF and the pressure
released. Open the lid and then remove the dead weight
valve cap and dead weight.
Failure to clean the operating control valve daily could
result in the fryer building too much pressure. Severe
injuries and burns could result.
2. Wipe both the cap and weight with a soft cloth. Make
certain to thoroughly clean inside cap, the weight seat, and
around valve orifice.
3.Dry the parts and replace immediately to prevent damage
