SECTION 3: GENERAL OPERATION

A. EXTERNAL MAIN POWER SWITCH (Junction Box)

Usually the kitchen’s external main power switch is left ON. If the
external main power switch was left in the OFF position, tur n it
ON as follows.
(1) Check that the water supply valv es to the steamer are open.
(2) Turn the steamers ON/OFF Switch to the OFF position. The
TIMED/MANUAL switch and timer settings are not important
in this procedure. The control panel circuits are not powered
while the ON/OFF switch is set to OFF.
(3) Refer to the external main power switch in Figure 3-1, and turn
ON electric power to the steamer. The s team generator(s) will
immediately start blowdown cycles. T he blowdown cycle lasts
3 minutes

B. DOOR INTERLOCK SWITCH (Optional)

The steamer compartments of a SteamCr aft Steamer may be
equipped with optional automatic steam c utoff switches, which turn OFF the production of steam to a
cooking compartment whenever the door to that compartment is opened. NOTE: Even though the
production of steam ends as soon as a door is opened, it ma y take up to a minute for residual steam in
the system to clear from the steam lines and the cooking compartment. To avoid possible injur y always
wait until this residual steam has cl eared before reaching into the cooking compartm ent.

C. POWER ON (AUTOMATIC FILL)

When each steamer compartment is turned on, it a utomatically fills the steam generator with water. Use
this procedure at the beginning of a sh ift to prepare the steamer for operation without starting steam
generation. When ready to start steam cooking, begin either the Timed or Manual Operat ing Procedure.
NOTE: The steamer automatically goes int o a standby heat mode, as soon as power is turned on t o the
steamer. This is either accomplished by a ther mostat or a timer, which will cycle the heating elements
ON and OFF to maintain a standb y water temperature of approximately 193°F, once the unit has come
up to temperature. This insures that the steam er begins producing steam almost immediately when an
actual cooking operation is select ed.
(1) Press the TIMED (top) end of the TIMED/M ANUAL switch on the control
panel.
(2) Turn the POW ER SWITCH (see Figure 3-2) to the ON Pos ition on the
steamer. The red indicator light on the control pane l lights, and water fills
the steam generator.
(3) When the generator is full, the steamer automatically stops water f low.
(4) Once the water has reached the s afe level, the elements are cycled ON and
OFF and automatically start to heat the water to the standby heat
temperature.
