b). DIAL TIMER MODELS
If the Timer is not zeroed, turn the dial counter clockwise until it points to the 0 mark.
3). Set the ON/OFF lever/switch to the ON position. As the steam generator fills with water, check
the following functions.
a). The red ON/OFF indicator light turns ON. The fill valve opens, and water begins to fill the
steam generator. The combustion blower turns on to purge the combustion chamber.
b). After a few minutes, water appears in the bottom of the probe cylinder. As the water level in
the steam generator rises;
Check that no water flows from the drain opening.
Check for plumbing leaks.
4). When the water in the steam generator reaches a safe operating level (which is the level of the
middle probe), the combustion blower shuts off and the pilot ignition cycle starts. The steam
generator begins to heat the water to stand-by temperature by lighting the pilot/standby burner.
a)
Water continues to fill the generator and the water level in the probe cylinder continues to
rise.
b)
The water in the probe cylinder stops rising, when water reaches the upper probe.
5). If the water level continues to rise above the tip of the higher probe, have a qualified service
representative check the probe circuit. Set the TIMED/MANUAL switches of both compartments
to MANUAL (or for ON/OFF Models set the compartment selector switches to ON), the
steaming cycle starts. Check the following functions.
•
If the water level in the steam generator is above the lower probe, the heating components
turn ON and begin to heat the water to steam. (For mechanical timer models only, the
SURECOOK
™ light comes ON)
•
After a few minutes steam begins to enter the compartment from the nozzles. A small
quantity of water may drip from the nozzles until steam clears the lines.
•
After a few more minutes the compartment will reach cooking temperature. When the
compartment reaches cooking temperature:
a.
24CGA6.2S & 24CGA10.2 (high capacity) units - the thermostat will close (the
SURECOOK
™ light will go OFF for mechanical timer units) the condenser solenoid
clicks open and condenser flow starts. A small stream of water flows from the
drainpipe. . If no drain water flows, check that the water supply valves are open, and
the lines are connected properly.
b.
STEAMSAVER
™
24CGA6.2SES & STEAMSAVER
™
24CGA10.2ES (high efficiency)
units
– the SURECOOK™ thermostat will close (the SURECOOK™ light will go OFF
for mechanical timer units). The burners will soon begin to cycle on the compartment
operating temperature thermostat. The condenser solenoid clicks when the condenser
box has reached maximum drain temperature. A small stream of water flows from the
drainpipe. The water stops when the drain water has cooled to the proper temperature.
•
With the unit in manual cooking mode the unit should steam continuously or cycle on
compartment temperature, depending on model, until turned OFF, set to the timed cooking
mode, or when the energy saver timer is activated (See Note below). After several minutes
of steaming, check for steam leaks around the door gasket.
6). As the unit continues to steam in Manual Cooking Mode, test the no-water/low water safety
circuit.
