valve ring
safety valve
Do not attempt to remove the valve cap while the fryer is
operating, or severe bums, or other injuries could result.
The operating control valve and safety relief valve are located side
by side at the back of the unit. The valve next to the pressure
gauge is the operating control valve, and the other valve is a
14 l/2 lb. safety relief valve.
Valves are working properly, when "OPERATING ZONE" is
indicated on the gauge by the pointer. The gauge pointer should not
normally exceed the operating zone. At 14 l/2 psi, the safety relief
valve opens to release steam pressure from the frypot.
Do not manually activate the safety relief valve. Hot steam
releases from the valve when the ring is pulled. Keep body
parts away from safety valve exhaust, or severe burns could
result.

Rinse thoroughly with hot water. Dry parts and replace imme-
diately to prevent damage or loss.
