3-1. OPERATING COMPONENTS

(Continued)
Safety Relief Valve Ring	DO NOT PULL THIS RING. SEVERE BURNS FROM
	THE STEAM WILL RESULT.
Pressure Gauge	Indicates the pressure inside the frypot.
Solenoid Valve	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
	becomes dirty or the teflon seat nicked, pressure will not build and
	it must be repaired per the Maintenance Section of the Technical
	Manual
Drain Valve	A two-way ball valve, normally in the closed position; turn the han-
	dle to drain the shortening from the frypot into the filter drain pan

	DO NOT OPEN THE DRAIN VALVE WHILE
	FRYPOT IS UNDER PRESSURE. HOT SHORTEN-
	ING WILL EXHAUST, AND SEVERE BURNS WILL
	RESULT.
Drain Interlock Switch	A microswitch that provides protection for the frypot in the event an
	operator inadvertently drains the shortening from the frypot 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 collection point for the condensation formed within the steam
	exhaust system; it must be removed and emptied periodically,
	usuallydaily
Shortening Mixing System	The unit is equipped with a shortening mixing capability to ensure
	the shortening is properly mixed to prevent an accumulation of
	moisture, causing boiling action in the frypot; the filter pump is
	activated by the controls, at preset intervals, to mix the shortening
Lid Latch	The fryer lid is equipped with a mechanical catch on the front
	of the lid which engages a bracket on the front of the frypot; this
	device holds the lid down while the lid is being locked into
	place, but is not meant to hold pressure in the frypot
