2. Standard
A. Set the timer to the desired cookin
time.
The timer must be set past five minutes to
chan
e the state of the timer control micro
switch contacts. If preheatin
is desired,
allow five to ten minutes (recommended)
of additional time at the be
innin
of the
cook cycle. The len
th of time will vary
with the type, size, temperature and
condition (frozen or thawed) of the product
and must be determined from experience.
B. Pull the steam control arm handle forward
and lock it by pullin
the handle down.
This closes the steam exhaust
ate valve
and opens the steam inlet
ate valve,
allowin
steam to enter the compartment.
C. Press the compartment power switch to
ener
ize the timer and red li
ht. The
balance of the cookin
sequence is
automatic. Durin
preheat, cooler air and
condensate are exhausted from the
compartment throu
h the steam trap
(condenser) until the temperature reaches
180°F, closin
the internal bellows.
Throu
hout the cookin
cycle, the
compartment pressure should be 6 psi if
equipped with a compartment pressure
re
ulatin
valve. On models without the
compartment pressure re
ulatin
valve,
the compartment pressure cycles with the
boiler pressure between 4 and 6 psi.
D. Approximately one minute before timer
reaches zero the steam control solenoid is
ener
ized to unlatch the steam control
arm. An internal sprin
will automatically
pull the arm to the rear. This closes the
steam inlet
ate valve and opens the
steam exhaust
ate valve, allowin
steam
and pressure to exit the compartment.
When the timer reaches "0" the red li
ht
shuts off and a buzzer sounds indicatin
the end of the cook cycle. Turn the
compartment power switch OFF to silence
the buzzer and remove power from the
compartment controls.
E. Turn the screw handle on the
compartment door counterclockwise
until
the
asket no lon
er seals a

compartment surface. After the remainin
steam escapes, move the latch paddle to
the left and open the door.

C. Press the compartment power switch to
supply power to the compartment controls.
The automatic compartment controls,
feature load compensated cookin
time by
utilizin
a thermal switch. With this
feature, when the compartment
temperature reaches 180°F (the
temperature at which preheatin
or
defrostin
is complete) the red li
ht will
then come on and the timer will start. For
a small food load, the delay time before
the timer starts mi
ht be a minute or less.
For a lar
e food load, the delay time could
be four to five minutes. Durin
