Condensation Drain Pan
The pressure gauge indicates the pressure inside the cookpot.
The solenoid valve is an electro-mechanical device that causes
pressure to be held in the cookpot.
The solenoid valve closes at the beginning of the frying cycle
and is opened automatically at the end of the frying cycle. If
this valve should become dirty or the teflon seat nicked,
pressure will not build up and it must be repaired per the
maintenance section.
The drain valve is a two-way ball valve. It is normally in the
. closed position. Pull the knob out to drain the shortening from
the cookpot into the filter drain pan.
DO NOT OPEN THE DRAIN VALVE WHILE
COOKPOT IS UNDER PRESSURE. Hot shortening
will exhaust from this valve. Severe burns will result.
The drain interlock switch is a microswitch that provides
protection for the cookpot in the event an operator inadver-
tently drains the shortening from the cookpot while the main
switch is in the POWER position. The switch is designed to
automatically shut off the heat when the dram valve is opened.
The condensation drain pan is the collection point for the
condensation formed within the steam exhaust system. It must
be removed and emptied periodically.
The lid stop bracket stops the upward motion of the lid
assembly. This allows the lid to be lifted to an upright position
with the rack removed allowing easier access to the cookpot
for filtering and cleaning.
