2. Standard
A. Set the timer to the desired cookin
g
time.
The timer must be set past five minutes to
chan
g
e the state of the timer control micro
switch contacts. If preheatin
g
is desired,
allow five to ten minutes (recommended)
of additional time at the be
g
innin
g
of the
cook cycle. The len
g
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

compartment throu
g
h the steam trap
(condenser) until the temperature reaches
180°F, closin
g
the internal bellows.
Throu
g
hout the cookin
g
cycle, the
compartment pressure should be 6 psi if
equipped with a compartment pressure
re
g
ulatin
g
valve. On models without the
compartment pressure re
g
ulatin
g
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
g
ized to unlatch the steam control
arm. An internal sprin
g
will automatically
pull the arm to the rear. This closes the

defrostin
g
is complete) the red li

then come on and the timer will start. For
a small food load, the delay time before
the timer starts mi
