The operating valves are located at the back of the unit. The
valve left of the pressure gauge is a 14 1⁄2 lb. safety relief valve,
and to the right of the pressure gauge, the operating valve.
Valves are working properly, when "OPERATING ZONE"
indicates on the gauge by the pointer. The gauge pointer
should not normally exceed the operating zone. If the pressure
builds to 14 1⁄2 lbs., the safety relief valve opens and releases
pressure from the frypot.
