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,
usually daily
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
