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.
PROBE INSPECTION
It is recommended that the generator be thoroughly
inspected for excessive scale and lime build-up on a
quarterly basis. In hard water areas or for units heavily
used, a shorter interval should be used. This inspec-
tion consists of the following:
Drain Plug - Remove clean-out port plug to check
for scale.
Probe - A check of lime build-up on the water
level probe assembly.
Controls - A check of all generator controls,
including the pressure switches.
