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

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.

Item Description Function

7 Safety Relief V alve The 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.

8 Pressure Gauge Indicates 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.

9 Solenoid V alve An electromechanical device that causes pressure to be held in

the frypot. The solenoid valve closes at the beginning of the cooking cycle and automatically opens at the end of the cooking cycle.

10 Drain V alve A two way ball valve, normally in the CLOSED position. T o

open the drain, pull the handle slowly outward, away from the fryer . This releases the oil from the frypot into the filter drain pan. Push it back in to close the valve.

DO NOT open the drain valve while frypot is under pressure. Hot shortening exhausts from this valve. Severe burns will result.

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.

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 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 PROCEDURES 8. 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

F (135o C).

Four product controls, use the “C” (up and down) buttons and select Idle. The controls will automatically

reduce the temperature to 250

F (121o C).

3-6. FIL TERING THE Cooking breaded products requires frequent filtering to keep SHORTENING the 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.

3-8 600

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.

ENVELOPE

F~LTE

NOTE: Approximately 10 to 12 filterings can be made with

one filter paper envelope, depending on several

conditions; the quantity and type of product fried and filtered, the type of breading used, and the amount of crumb accumulation left inside the filter drain pan. When the filter screen assembly and filter paper become clogged and pumping flow rate slows down,

clean the screen assembly and change the filter

envelope. See procedure on page 3-11.

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

11. If cooking 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. Move the main power switch to the OFF position.

2. Remove and empty the condensation drain pan.

3. Disconnect the filter union and remove the filter drain pan from beneath the fry pot. The filter drain pan is provided

(Continued)

Watch cleaning solution constantly to make sure it does NOT boil over causing damage to controls.

If the cleaning solution starts to foam and boil over, DO NOT CLOSE THE FRYER LID, severe burns could result.

7. Let the cleaning solution stand for 15 to 20 minutes, with the unit turned off.

8. Use fryer brush (Henny Penny part no.12105), to scrub the inside of the frypot, the lid liner, and the counter top of the fryer. Never use steel wool, it deteriorates the stainless steel.

Do not use the cleaning solution on the lid or the lid hinge. These aluminum parts will corrode if the PHT cleaner contacts them. Also, Do not use abrasive cleaners, or cleaner containing chlorine, bromine, iodine, or ammonia chemicals on the stainless steel. Deterioration of the stainless steel will result.

9 Open the drain valve and drain the cleaning solution from the

frypot into the drain pan and discard.

10. Replace the empty drain pan, close the drain valve, and refill the frypot with hot water to proper level.

1 1. Add approximately 4 ounces of distilled vinegar and reheat the

vinegar solution to 195

F (91o C), or use the Clean mode on

electronic controls.

12. Using a clean brush, scrub the interior of the frypot and lid liner. This neutralizes the alkaline left by the cleaning compound.

13. Drain the vinegar rinse water and discard.

14. Rinse down the frypot, using clean hot water .

15. Thoroughly dry the drain pan, and the frypot interior .

NOTE: Make sure the inside of the frypot, the drain valve

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.

14. Set the thermostat to 275°F (135 “6).

250 “F (121 “C) 275 “F (135 “C) 114 turn clockwise.

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.

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.

2. Remove the thermostat and high limit bulb holder from the heating element inside the frypot.

3. Remove the heating element wires from the contactor. Label each so it can be replaced in the same position on the new element.

4. Slide the element spreaders to the center of the heating element.

Remove the brass nut and washer, which secure the ends

5. of the element through the frypot wall.

Remove the heating element from the frypot by lifting the

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.

CAP ORIFICE WEIGHT

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 or loss.
