c. If the float cylinder water level drops below the initial fill level, the
water fill valve opens and fills the generator. When the float cylinder
water level is above one inch, the heater coil turns on. A dull roaring
sound indicates the beater is working and the unit is beginning to
generate steam.
d. As the unit generates steam, the water level fluctuates and a clicking
sound is heard as the solenoid opens and closes the fill valve. The level
in the float cylinder rises and falls about 1/4 inch as the fill valve
operates.
e. Check for steam leaks around the door.
f. 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.
g. After about 30 seconds, steam stops entering the cooking compartment.
11. Turn the SteamCraft 3.1 off by pressing the OFF (bottom) end of the
ON/OFF switch. The red indicator on the switch turns off immediately,

3 minutes.
12 When blowdown is complete, turn the steamer off at the main power
switch.
13. Install the side panel and secure it in place with two screws (see Figure 2-
16). After completing the Initial Setup and Blowdown Inspection

Operating Tests • Dial Timer Control Panel
This procedure is followed for SteamCraft 3.1's with dial timer control panels
(Figure 2-24). The test consists of observing and timing various steamer
functions in the MANUAL operating mode, and in the TIMED operating
mode. To become familiar with the functions observed and timed, read
through all steps of the procedure before starting the steamer.
The times listed in the procedure are approximate and may vary with the
temperature of the equipment, the temperature and pressure of the supply
water, beater supply voltage, and pipe lengths. A stopwatch, wristwatch with a
second hand, or one with a digital readout in seconds is required for timing the
functions.
1. Remove the right side access cover.
2. Perform the Setup and Blowdown Inspection procedure. Leave the control
settings as they are at the end of the procedure.
• The main power switch is ON.
• The ON/OFF switch is OFF (indicator not lighted).
