CHAPTER 2
GENERAL OPERATION
A. MAIN EXTERNAL POWER SWITCH
Usually the steamers main external power switch is left ON. If
the main external power switch was left in the OFF position, turn
it ON as follows.
1.
Check that the water supply valves are open.
2.
Turn the ON/OFF levers/switches to the OFF position.
3.
The TIMED/MANUAL switch and timer settings are not
important in this procedure. The control panel circuits are
not powered while the ON/OFF levers/switch is set to OFF.
4.
Refer to the main external power switch in Figure 2-1 and
turn on electric power to the steamer. The steam generators
will immediately start blowdown cycles. The blowdown cycle
lasts 3 minutes
(Refer Ch.5 “Shutdown and Cleaning
procedure” for blowdown cycle).
B. DOOR INTERLOCK SWITCH
The steamer compartments of the Gemini Steamer are equipped with automatic steam cutoff switches,
which turn OFF the production of steam to a cooking compartment whenever the door to that compartment
is opened.
NOTE:
Even though the continued production of steam ends as soon as a door is opened, it may
take up to a minute for residual steam in the system to clear from the steam lines and the cooking
compartment. To avoid possible injury always wait until this residual steam has cleared before reaching into
the cooking compartment.
C. POWER ON (AUTOMATIC FILL)
When each steamer compartment is turned ON, it automatically fills its steam generator with water. Use this
procedure at the beginning of a shift to prepare the steamer for operation without starting steam generation.
When ready to start steam cooking, begin either the Timed or Manual Operating Procedure.
1.
Press the TIMED (top) end of the TIMED/MANUAL switch (for ON/OFF models set the selector switch
to OFF.
2.
Turn the ON/OFF lever/switch to the ON position to energize the steamer control panel. The red
indicator light on the control panel lights, the combustion blower turns ON to purge the generator and
water fills the steam generator.
NOTE:
The ON/OFF lever/switch must be turned fully to the ON position to START the steamer.
3.
When the generator is full, the steamer automatically stops water flow.
4.
Once the water has reached the minimum operating level, the blower turns OFF and the pilot/standby
burner lights to heat the water to the standby temperature.
D. LIGHTING AND SHUTDOWN INSTRUCTIONS
DO NOT TRY TO LIGHT THE BURNERS OR PILOT WITH A FLAME. THE PILOT AND BURNERS ARE
SELF IGNITING.
The Gemini Steamer has an electronic ignition system, which automatically lights the pilot and burners,
senses the flame and controls gas flow. This provides precise burner control, safety ignition, and
shutdown.
