    If a problem occurs during the first operation of a new fryer, re- check the installation per Section 2 of the Operator’s Manual. Before troubleshooting, always recheck the operating procedure per Section 3 of the Operator’s Manual. The Henny Penny Pressure Fryer has many safety features incor- 1-2. SAFETY porated. However, the only way to ensure a safe operation is to fully understand e proper installation, operation, and maintenance procedures. The instructions in this manual have been prepared to aid you in learning the proper procedures.

    Model 500/600 2-14. PRESSURE Lid Cover Assembly REGULATION/ EXHAUST (Continued) Description Generally, the lid spindle, the limit stop, the cover, the hinge, the inner and the reversible gasket comprise the lid cover assembly. Lid Cover Removal The lid cover is easily removable for cleaning or service. 1. Close lid cover and turn the spindle counterclockwise until it stops. 2. Pull the lid release pin on front of crossbar, lift the latch, and raise the crossbar.

    Lid Hinge Spring The hinge spring needs to be replaced if it is broken, cracked or otherwise loses its tension. A special spring installation tool greatly simplifies this procedure is available from the factory. (Henny Penny part number 21642) 1. Pull out on retaining pin knob on the front of the cross bar to release lid cover. (Refer to lid cover removal instructions.) 2. Lift the cross bar up and away from the lid.

    Model 500/600 2-14. PRESSURE REGULATION/ Latch Spring EXHAUST (Continued) Installation The latch on the crossbar must have the external coil-type latch spring mounted on the latch pin. If a latch spring is weak or bro- ken, it must be replaced with a new spring, part number 33480. To avoid severe burns and injuries make sure the lid is secure during a cook cycle.

    2. Use a thin blade screwdriver to pry lid liner from the cover. 3. Clean the liner and the inside of the cover. Replace the liner and screws. Reversing the Lid Gasket The gray rubber gasket surrounding the inside of lid is designed to be reversed. Henny Penny recommends that this be done on a quarterly basis. Purpose Because of heat expansion and the pressure used for the cooking process, the gasket is constantly under extreme stress. Reversing the lid gasket on a quarterly basis will help to assure that the fryer will not lose pressure through leakage.

    Model 500/600 2-14. PRESSURE Reversing the Lid Gasket REGULATION/ (Continued) EXHAUST (Continued) 1. There are two lid liner screws on either side of the lid cover. Back these four screws out about 1/2 inch. Step 1 2. Open lid and, using a thin blade screwdriver, pry out the gasket at the corners. Remove the gasket.

    Model 500/600 2-14. PRESSURE Reversing the Lid Gasket REGULATION/ (Continued) EXHAUST (Continued) Begin the installation by installing the four corners of the lid gasket. Lid Limit Stop Adjustment The lid limit stop, with proper adjustment, prevents unnecessary overtightening of the spindle, and as a result, extends the life of the lid gasket.

    Model 500/600 2-14. PRESSURE Lid Limit Stop REGULATION/ Adjustment (Continued) EXHAUST (Continued) It may be necessary to remove knobs and change their position in order to align the red knob with the red knob on the lid cover lid latch. When in the normal operating position, both red knobs should be aligned. 6. Adjust the limit stop by turning it counterclockwise until it stops against the bottom hub of the spindle. 7. Tighten Allen set screws. 8. If the lid cover fails to seal properly, steam will escape around the gasket during the frying operation. The limit...

    Model 500/600 2-14. PRESSURE REGULATION/ EXHAUST (Continued) 5. Remove the ball from the locking collar. This may be accomplished by lightly tapping steel ball with a hammer. Step 5 6. Remove and inspect the idle nut. Step 6 7. Thread the spindle out of the acme nut. 8. Loosen the Allen set screw in the outer ring of limit stop.

  • Page 91

    Model 500/600 2-14. PRESSURE REGULATION/ EXHAUST (Continued) The acme nut must be changed when there is excessive play and movement between the spindle and the acme nut. 9. Using a nylon tape type wrench unthread the limit stop collar from the acme nut.

    Model 500/600 2-14. PRESSURE REGULATION/ EXHAUST (Continued) 12. Remove the locking pin and spring. Inspect and replace if necessary. When reinstalling the locking pin, be certain it is put back in Step 12 its original position. The angled side of the pin should be to the right. Step 13 13. Use a magnet to remove the ball seat. Inspect and replace if necessary.

    Model 500/600 2-14. PRESSURE 17. Slip spindle through limit stop, hold idle nut against acme REGULATION/ nut, and thread spindle through both. There should be 20 to EXHAUST (Continued) 60 thousandths between acme nut and idle nut. To increase dimension, turn idle nut counterclockwise; to decrease turn clockwise.

    Model 500/600 2-15. FILTERING SYSTEM (Continued) Installation 1. Attach the filter rinse hose with its quick disconnect female fitting to the other half male fitting inside the door, next to the filter valve handle. 2. To do this slide back the spring ring on the female end of the quick disconnect fitting and let it snap into place over the other half male fitting. 3. With a quick tug on the hose, insure the quick disconnect is locked into position. Step 1 Filter Valve Description The filter valve is a 3/8 inch two-way stainless steel ball valve. If this valve should develop leaks the entire valve must be replaced. To avoid electrical shock or property damage, move the power switch to “OFF” and disconnect main circuit breaker, or unplug cord at wall receptacle.

    Model 500/600 2-15. FILTERING SYSTEM (Continued) Filter Pump Repair The two most common causes for a fryer’s inability to pump shortening is that the pump is clogged with breading or solid shortening has cooled and solidified in the lines and pump. To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

  • Page 96

    Model 500/600 2-15. FILTERING SYSTEM (Continued) Pump Removal 1. If the pump needs to be replaced, loosen one inch nuts from the outflow and inflow lines. Then remove the two bolts holding the pump to the motor with a 1/2 inch wrench. 2. The shaft seal should remain on motor shaft, or if leaking, could be replaced at this time.

  • Page 97

    Model 500/600 2-15. FILTERING SYSTEM Pump Removal (Continued) (Continued) 4. To replace the pump and motor assembly, insure the main power has been removed from the fryer. To avoid electrical shock or property damage, move the power switch to OFF and disconnect main circuit breaker, or unplug cord at wall receptacle.

    Refer to the Technical Manual illustrated parts breakdown for kit identification. Conversion must be accomplished by an authorized Henny Penny dealer or service representative, or personal injury could result. Service Hints On natural gas installation, the gas pressure regulator on the automatic gas control valve is factory set at 3.5 inch water column.
