Function
The safety relief valve is set at 14.5 PSI (99.9 KPa). In the
event that the dead weight valve becomes clogged, the safety
valve releases excessive pressure, keeping the frypot at a
maximum of 14.5 PSI (99.9 KPa). If this occurs, turn the main
power switch to the OFF position to release all pressure from
the frypot. Also, clean the dead weight valve at this time.
DO NOT pull the Safety Relief Valve Ring, or severe burns
will result.
Indicates nominal pressure within the frypot. This gauge is not
used to calibrate the dead weight assembly. Operating pressure
of the dead weight assembly is preset at the factory .The gauge
is used as an indication of pressure build up within the frypot.
An electromechanical device that causes pressure to be held in
the frypot. The solenoid valve closes at the beginning of the
cooking cycle and automatically opens at the end of the cooking
cycle.
A two way ball valve, normally in the CLOSED position. To
open the drain, pull the handle slowly outward, away from the
fryer. This releases the oil from the frypot into the filter drain
pan. Push it back in to close the valve.
DO NOT open the drain valve while frypot is under
pressure. Hot shortening exhausts from this valve.
Severe burns will result.
A microswitch that provides protection for the frypot in case the
operator drains shortening from the frypot while the main
switch is in the POWER position. The switch is designed to
automatically remove power from the heating elements when
the drain valve is open.
A two way ball valve which operates in conjunction with the
filtering system. With the handle in the open position (handle
facing vertical by turning it counterclockwise) and the main
power switch in the PUMP position, this valve directs the
filtered shortening from the drain pan back to the frypot. To
close the filter valve, turn it clockwise to the horizontal position.
