Installation
Operation
Maintenance Daily
Service
1. Position steamer on level surface and plug power cord into 3-hole 120 volt AC grounded receptacle. If an adapter is used, it must be grounded properly.
2. Pull out water pan and fill with distilled (NOT HOT OR BOILING) water to
1
/4" from the
top of the water pan baffles; then close drawer. Unit is now ready for operation.
1. Move rocker switch to ON position. The ready light will come on but you must allow 15-20 minutes to reach operating temperature.
2. Open food drawer, place food in pan; close drawer and turn dial of timer to time required per cooking guide. Depress push button at center of timer (ready light will go out) and cycle will proceed. When the cycle has completed, ready light will come on and buzzer will sound for 10 seconds. At the end of the cycle open drawer and remove food.
3. Manual Operation: Depress square switch approximately 1 - 2 seconds.
The food pan is removed by lifting up. Clean the inside thoroughly and wipe the outside to remove any material which might have accumulated.
To remove the food drawer, pull the drawer out until it stops, release stop located at rear underside of drawer to unlock, and pull out the frame. Wipe the drawer and frame clean and return by inserting the drawer slide into the slide of the frame, then push the food pan to the rear until the lock engages automatically.
DANGER: READ AND UNDERSTAND THIS BULLETIN THOROUGHLY BEFORE STARTING ANY TROUBLE SHOOTING. AN INADVERTENT SERVICE ERROR COULD RESULT IN SEVERE PERSONAL INJURY OR DEATH. ONLY A TRAINED EXPERIENCED SERVICE TECHNICIAN SHOULD ATTEMPT ANY REPAIR PROCEDURE.
Qualified serviced agencies are available at most locations - Refer to EmberGlo listing of AUTHORIZED SERVICE AGENCIES included in Standard Equipment Catalog.
Note: Before attempting service, unplug power cord. For service or examination, all "working parts" of the steamer are exposed by removing first the cabinet top, then the back. The wiring diagram and spare clean out gasket is located on inside of back.
Electric Switch/Thermostat
The on-off switch should audibly "click" when operated manually. To determine if electrically operative, a continuity check should be made.
The thermostat is factory calibrated and non-adjustable and should not be repaired. Replace if
defective.
Pump System
The pump system is an electrical vibrator type which is controlled by the main timer. It supplies power to the solid state (#606) recycle timer. A failure in this circuit may be traced from the main timer thru the solid state timer. Please note that the "on" time of the solid state timer may be as short as .1 second and then 10 seconds "off" . See the schematic for test points. If the pump is operating but not pumping, check that the filter mounted on the inlet side of pump is not clogged, if so, remove and clean. If still not streaming, refer to the “Steam Generator” section of this manual.

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.

Remove the old gaskets from the discharge plate and scrape residue silicon from the discharge plate. Clean the groove of the discharge plate. To install the new gaskets in the discharge plate grooves, as shown in Figure 1, first apply a bead of Dow Corning 732 or General Electric 159 RTV silicon adhesive at the ends of the gasket then butt the two ends of the individual gasket. Place discharge plate and silicon assembly on the steamer (gasket facing towards generator) so that steam holes line up with the twelve round holes in steam chamber. Place the generator on the above assembly so that mounting holes line up with the sixteen round holes in the discharge plate. Tape the carriage bolts in place from inside steam chamber and then tighten the nuts with lock washers. Remove all tape.
3. To Replace. Remove the old gaskets from the discharge plate and scrape residue silicon

Place the generator on the above assembly so that mounting holes line up with the sixteen round holes in the discharge plate. Tape the carriage bolts in place from inside steam chamber and then tighten the nuts with lock washers. Remove all tape. Place casting on plate carefully so that holes align properly. Replace screws and tighten securely. Allow the RTV to set approximately 24 hours before operating unit.
Heating and Cooking Guide
These suggestions are made only to help the operator get started. Since each location will have different portions and different requirements, each operator must determine his own operation habits. Please remember that the steamer conserves its steam in the drawer and therefore does not often need repeated shots. The main exception is when frozen product must be defrosted.
If a product is at room temperature or refrigerated, start with 2 shots. This ensures that the food pan is full of steam.
If a product is frozen, start with 3 shots because condensation on the cold product eliminates the steam quickly.
