COOKING CYCLE TEST
General
During a cooking cycle, the gas heating system will cycle on and off as necessary to maintain steam pressure in the generator. When the steam pressure in the steam generator reaches 4 psi for the first time after machine is switched on, the steam header pressure relay latches on and supplies power to compartment controls. Ready light will illuminate (header pressure relay remains latched until the machine is switched off).
Test operation of the cooking compartment controls.
1.With both timer knobs at the off position, open the compartment doors.
2.Observe that no steam has entered the cooking compartments.
3.Close the doors.
4.Set both timer knobs at 2 minutes.
5.Confirm that the ready lights go off, the cooking lights come on, and steam begins to enter the compartments.
6.After one minute, open both doors.
7.Observe that steam has ceased to enter each compartment, cooking lights go back to ready, and one minute is remaining on each cook timer.
8.Close the doors.
9.Confirm that steam delivery and cook timing resume.
10.Observe the floor drain to ensure that live steam from the compartments is being cooled by cold water from the cold water condenser solenoid valve.
11.When the timer knobs reach 0, confirm that the buzzers sound, steam delivery ceases, cooking lights go off, and ready lights come on.
12.To silence the buzzers, turn the timer knobs to off position.
13.Turn the main power switch off to remove power from the steamer, and confirm that the red light goes out and generator drains.
