Timers
There are three timers in this system.
1. Push-button Automatic Reset - times length of cycle in minutes and supplies power to the
solid state timers. To determine if timer is functioning properly a volt meter or test lamp may
be used. See schematic for test points.
2. Solid State Programmable Recycle #606 - times length of shot (.1 second adjustable) and
time between shots (10 seconds adjustable). To determine if timer is functioning properly, a
volt meter or test lamp may be used. See schematic for test points.
3. Solid state delay interval programmable timer - 6013 - buzzer item delay and buzzer on time.
Factory set at .1 second delay and 10.0 second on time. To determine if timer is functioning
properly, a volt ohmmeter or test lamp may be used. See schematic for test points.
Dip Tube and Spring
If the dip tube does not enter the water pan properly it must be replaced. When replacing, the
open end or point of hook must be at the bottom and the eye must be in a vertical plane, like a
coin standing on edge.
Steam Generator
1. To Clean. Remove cabinet top and generator insulation. This will expose a square plate on
the generator, which is removable for cleaning water passages.
Check the three exposed holes when the clean-out cover is removed. If any of these
holes are clogged, clean them out by hand-twisting a
7
/ 64" drill for the center hole and a
3
/16" drill for the two side holes.
After thoroughly cleaning the three holes, plug in power supply and operate momentary
switch to steam unit. THE UNIT MUST BE HOT. Operate several times to blow out any
accumulation.
Replace the clean out cover, using new gasket. With the unit hot, operate pump with the
momentary switch. The unit should steam properly. If it does not, and the pump is operative
as detailed under PUMP SYSTEM, the entire generator assembly is probably limed and must
be disassembled and cleaned or replaced.
To clean generator assembly, separate casting from plate and clean lime from cavity in
casting.
Caution: Do not damage plate by scratching or polishing the finish.
2. To Remove.
Disconnect the water riser tube.
Disconnect electric wiring at the two terminals.
Remove 16 hex nuts. Note: Remove food drawer and hold screws up to prevent turning.
Separate generator from discharge plate.
