(14)When the water in the steam generator reaches a safe operating level (which is the level of the
lower probe), heating elements and the convection fan will come ON and the unit will begin
warming up to the standby heat temperature. Open the door; the heating elements and
convection fan will turn OFF.
a) Water continues to fill the generator and the water level in the reservoir continues to rise.
b) The water in the reservoir stops rising, when water reaches the upper probe.
i
If the water level continues to rise above the tip of the higher probe, see the
troubleshooting guide on page 16. If the problem persists have a qualified service
representative check the probe circuit.
(15)Close the compartment door to close the door interlock circuit.
a) The heating elements and the convection fan will come back ON and the unit will begin
warming up to the standby heat temperature.
b) The unit will continue to heat up until the standby heating temperature is reached.
i
When the standby heat temperature is reached, the “SureCook” indicator lights and the
convection fan will turn OFF, and the heating elements will be de-energized.
c) If the unit is left in this mode the heating elements and convection fan will intermittently
cycle ON and OFF to maintain the standby heating temperature.
(16)Set the TIMED/MANUAL switch to MANUAL (or for ON/OFF Models set the selector switch to
ON), the steaming cycle starts. Check the following functions.
x
The heating elements, the condenser water and convection fan will turn ON and the water
will begin to heat to steam. After a few seconds, a stream of water flows from the drainpipe.
x
After a few more minutes the compartment will reach cooking temperature. The heating
elements, condenser water and convection fan will continue to be ON for as long as the
unit remains in manual (or ON for ON/OFF Control Models).
x
With the unit in manual cooking mode (or for ON/OFF Models, when the unit is ON) the unit
will continue to operate at the cooking temperature for up to 60 minutes, or it is set to the
timed cooking mode. After several minutes of steaming, check for steam leaks around the
door gasket.
NOTE: That after 60 minutes of uninterrupted operation in the manual mode or for an
ON/OFF unit left “ON” (continued operation without opening the doors, or switching the unit
to the timed mode), the unit will automatically drop back down to the standby heating
temperature. This is done to save energy and water, and maximize equipment operating
life. To return the unit to the cooking temperature, simply open and close the compartment
door.
(17)As the unit continues to steam in Manual Cooking Mode, test the no-water/low water safety
circuit.
a) Close the manual water supply valves to the steamer.
b) When the water level drops below the lower water safety cutoff point (the lower probe). The
heating system (including the condenser water and convection fan) will automatically
shutoff, and the production of steam will cease.
c) Re-open the manual water supply valve to the steamer. The steamer’s controls
automatically refill the steam reservoir with water to the safety level and the steamer will
resume steaming.
(18)When the TIMED/MANUAL switch is set to TIMED (and the timer is zeroed), the steam
generating cycle stops. Press the TIMED end of the TIMED/MANUAL switch.
