Remove electrical power supplied to 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.
Model 690 2-8. PRESSURE REGULATION The Henny Penny Fryer uses pressure as one of the compo- nents of the cooking process. Once the lid is sealed to the frypot and the solenoid valve closes, a deadweight valve maintains the correct pressure in the frypot.
Model 690 2-10. REVERSING THE LID The gray rubber gasket surrounding the inside of the lid is GASKET designed to be reversed. Because of heat expansion and the pressure used for the cook ing process, the gasket is constantly under extreme stress. Reversing the lid gasket will help to ensure that the fryer will not lose pressure through leakage.
Model 690 2-11. LID COUNTERWEIGHT The Lid Counterweight in the back of the fryer balances the CABLES 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.
Model 690 2-12. PRESSURE PAD The pressure pads are plastic strips that the lid cam presses against to seal the lid. 1. Raise the lid. 2. Remove the four screws securing the lid cover and remove cover. 3. Push the lid cam back, off the pressure pads. 4.
Fryer should be operating at 12 psi (827 mbar), or serious burns could result. 2-14. CLEAN THE NYLATRONS 1. Spray Henny Penny biodegradable, food safe, foaming degreaser (part no. 12226) on Nylatrons. 2. Raise lid up and down several times to spread degreaser.
Model 690 2-15. SOLENOID VALVE This is an electromechanical device that causes pressure to be held in the frypot. 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 nicked, pressure will not build up.
Page 31
Model 690 2-15. SOLENOID VALVE 5. If the core-disc assembly is sticking due to buildup of (Continued) shortening, breading, and food particles, proceed with the following steps: a. Unscrew the solenoid bonnet assembly from solenoid valve body. b. Remove the solenoid bonnet assembly and bonnet gasket.
Model 690 2-15. SOLENOID VALVE 13. Wet O-ring around seat with water and insert O-ring (Continued) assembly (flat side first) in valve through “IN” side of body. Use an eraser end of pencil and press in the Teflon seal until it snaps into place. BE CAREFUL NOT TO MAR OR NICK THE SEAT.
Model 690 2-16. DEADWEIGHT VALVE (Continued) DO NOT PULL THE RING ON SAFETY RELIEF VALVE. HOT STEAM WILL BE RELEASED AND SEVERE BURNS WILL RESULT. 1. AT THE END OF EACH DAY’S USAGE OF THE FRYER, THE DEADWEIGHT VALVE MUST BE CLEANED.
Model 690 2-17. REMOVAL & CLEANING 2. Use a wrench to loosen the valve from the pipe tee; turn OF SAFETY RELIEF VALVE counterclockwise to remove. (Continued) 3. Clean the inside of the pipe tee with hot water. Turn the safety relief valve towards the rear of fryer when reinstalling safety relief valve.
Model 690 2-19. GAS CONTROL VALVE The gas control valve sends regulated gas to burners when the controller calls for heat. The control valve can be turned on or off. In ON position, and power switch ON, a spark ignitor lights a standing pilot, and when the control calls for heat, the valve is opened and the burners are ignited.

Model 690 2-20. BLOWER ASSEMBLY The blower motor circulates air into the burner area to create the correct heat for the fryer. If the blower fails, a sensor will shut the power control valve down. 1. Make sure unit is off, and close and lock the lid. Lid should be in locked down position.
Model 690 2-21. TRANSFORMER The transformer reduces the voltage down to accommodate those components with low voltage. 1. Remove electrical power supplied to the unit. 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 690 2-22. AIRFLOW SWITCH The airflow switch senses the flow of air coming from the blower. If the airflow is reduced below a set amount, the switch will cut power to the control valve, which shuts the burners down. Replacement 1.
Model 690 2-23. DRAIN MICROSWITCH Upon pulling out on the drain handle, the microswitch should be activated and the unit will not heat, but when the handle is pushed back, the unit should operate properly. The bracket on the microswitch is slotted so it can be adjusted backward or `forward.
