Standard
A.
Set the timer to the desired cooking time.
The timer must be set past five minutes to
change the state of the timer control micro
switch contacts. If preheating is desired,
allow five to ten minutes (recommended)
of additional time at the beginning of the
cook cycle. The length 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 pulling the handle down.
This closes the steam exhaust gate valve
and opens the steam inlet gate valve,
allowing steam to enter the compartment.
C.
Press the compartment power switch to
energize the timer and red light. The
balance of the cooking sequence is
automatic. During preheat, cooler air and
condensate are exhausted from the
compartment through the steam trap
(condenser) until the temperature reaches
180°F, closing the internal bellows.
Throughout the cooking cycle, the
compartment pressure should be 6 psi if
equipped with a compartment pressure
regulating valve. On models without the
compartment pressure regulating 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
energized to unlatch the steam control
arm. An internal spring will automatically
pull the arm to the rear. This closes the
steam inlet gate valve and opens the
steam exhaust gate valve, allowing steam
and pressure to exit the compartment.
When the timer reaches "0" the red light
shuts off and a buzzer sounds indicating
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 gasket no longer seals against the
compartment surface. After the remaining
steam escapes, move the latch paddle to
the left and open the door.

Press the compartment power switch to
supply power to the compartment controls.
The automatic compartment controls,
feature load compensated cooking time by
utilizing a thermal switch. With this
feature, when the compartment
temperature reaches 180°F (the
temperature at which preheating or
defrosting is complete) the red light will
then come on and the timer will start. For
a small food load, the delay time before
the timer starts might be a minute or less.
For a large food load, the delay time could
be four to five minutes. During preheat,
cooler air and condensate are exhausted
from the compartment through the steam
trap (condenser) until the temperature
reaches 180°F, closing the internal
bellows. Throughout the cooking cycle, the
