7. Timed Test 3: Zero the Timer and start timing upon pressing the TIMED end of the
TIMED/MANUAL Switch.
Press the TIMED end of the TIMED/MANUAL Switch
a. Immediately:
The heater turns off and the condenser flow stops.
•
b. 30 Seconds:
Steam stops entering the cooking compartment.
•
Open the cooking compartment door for 2-3 minutes to allow it to cool slightly.
8.
9. Close the cooking compartment door and continue testing.
10. Set the TIMED/MANUAL Switch to Timed.
11. Set the Timer for 10 minutes.
Press the number keys 1, 0, 0, 0.
•
The display reads 10:00 (ten minutes, zero seconds).

12. Press the START/STOP key.
a. The steam generating cycle starts. When the float/probe assembly cylinder water level is
1 inch from the bottom of the cylinder, the heater coil turns on. A dull roaring sound indicates
the heater is working and steam is being produced.
b. The same sequence observed in 6 and 7 repeats, EXCEPT:
The Timer controls the steam generating cycle.
•
Note: The elapsed times are shorter because the steam generator and cooking
•
compartment are already hot.
c. The Timer display reads PAUS until the cooking compartment reaches cooking temperature.
Then the Timer begins to count down.
d. The condenser solenoid clicks open and a small stream of water flows from the drainpipe.
e. When the float/probe assembly cylinder water level drops below the initial fill level, the water
fill valve opens and fills the generator.
f. As steam is generated, the water level in the generator rises and falls and a clicking sound
indicates the solenoid valve is opening and closing the fill valve. The water level in the float/
probe assembly cylinder rises and falls about ¼ inch as the fill valve operates.
g. Check for steam leaks around the cooking compartment door.
h. When the Timer counts down to zero (00:00), the heaters turn off, the condenser flow stops,
and the buzzer sounds continuously. Press the START/STOP key to silence the buzzer.
i. After about 30 seconds, steam stops entering the cooking compartment.
13. Turn the SteamCraft off by pressing the OFF end of the ON/OFF switch. The red indicator light
goes out and the 3-minute automatic blowdown cycle starts.
14. After the blowdown is complete, turn OFF the Main External Power Switch.
15. Replace the side panel. After passing all the tests, the SteamCraft is ready for use.
