When the power is on (Figure 4), the control board
is activated and a thermostat senses generator tem-
perature. If generator temperature is below the factory
preset setpoint, power is applied to the generator until
setpoint is reached. The generator is constantly moni-
tored and power is regulated to maintain temperature
setpoint.
MeNu ButtoNs
When any menu button is pressed and released, power
is supplied to the solenoid, the solenoid operates and
water sprays onto the heated steam generator. The
water flashes immediately into live steam and shoots
down onto the product.
One of two operational modes can be used:
single
shot
or
timed Cycle
siNGle shot
The
siNGle shot
button (Figure 4), is pressed to
initiate a single timed shot. The control board applies
power to the solenoid and a timed “shot” of steam
occurs.
tiMed CYCle
The desired timed cook cycle (up to 99 minutes, 59
seconds) is selected by pressing and releasing any of
the four menu buttons (Figure 4). The main control
board applies power to the solenoid at regular intervals
for the duration of the displayed cycle time. The dis-
play counts down to zero when the cycle is complete,
then reverts back to the original programmed cycle
time and the unit is ready for the next cycle.
