4 SM-GSSP BOILERLESS STEAMER
When the MANUAL button is pushed, the heat remains on continuously and
produces full steam.
When the TIMED button is pushed, the display allows time to be entered in hours
and minutes, the heater turns on producing full steam, and the timer counts
down to zero automatically switching to HOLD with audible alert and timer
begins to count up. Heaters will cycle on and off to maintain cavity temperature
between 160º and 170ºF. At any time while in TIMED & HOLD mode, the “+1m”
button will add one minute of cook timer or transition HOLD to TIMED mode for
one minute turning heaters on producing full production.
When the door is open the display shows the door open icon. If “Compensating
Timer” set to “On”, the timer stops counting down, and the heater stops heating.
Close the door to resume timing and heating. If “Compensating Timer” is set
to “Off”, then timer will continue to count down even if door opens and closes.
When the timer counts down to zero the display shows three dashes, the beeper
sounds, and the heater cycles on and off slowly to keep the water temperature
just above the ready temperature. Push the CANCEL button to stop the beeper.
The “X” button may be pushed at any time to stop the MANUAL or TIMES modes.
If the door is open during the cooking process, the door interlock switch causes
power to be removed from the convection motor. The relay or gas valve opens
the circuit of the source of heat, instantly reducing the heat from the steam
reservoir.
WATER ENTRY INTO STEAM RESERVOIR
CAUTION: A SCALED RESERVOIR OR DEBRIS WILL CAUSE ERROR CODES. WHEN A
PROBE HAS EXCESSIVE SCALE IT WILL NOT FUNCTION PROPERLY.
NOTICE: WHEN POWERED OFF, THE CONTROLS EMPTY THE STEAM RESERVOIR.
On power up, the boiler goes through a fill/drain diagnostic to verify the condition
of the water level probes and drain. If either probe is not responding, a error code
is generated.
The LOW WATER probe determines if there is a full and proper level of water in
the steam reservoir. If the water level goes down, he probe is open by the water
level getting low. This causes the water fill valve for that steam reservoir to turn
on to permit water to enter the steam reservoir.
Water will continue to enter the steam reservoir until the level of water is high
enough to close the LOW WATER probe. This determines that the steam reservoir
is full and the water supply solenoid valve is turned off stopping the water flow
to the stem reservoir.
When the LOW WATER probe is open, there is a 3 second delay before the water
fill valve opens. This is to take into account the rising and lowering of the water
level due to the bubbling action of the boiling water in the steam reservoir. If the
probe is open for more than approximately 3 seconds, then the water fill valve
is activated.
SERVICE CODES
Error codes are normally cause by probes or timing issues (fill time and drain
time).
A error code is generated when the electronic controls are blind to the status
of the steam reservoir (i.e., probes are not working) or by a blocked drain. The
error may stop the machine from running and the error code number will be
displayed as a pop-up message on the touchscreen. Error codes protect the
steam reservoir from irreparable damage.
HEATER CONTROL
NOTICE: IF THE DOOR IS OPEN, THE HEATING CIRCUIT WILL NOT BE ENERGIZED AND
THE HEATING CIRCUIT WILL NOT TURN ON UNTIL THE DOOR IS CLOSED.
After the reservoir is initially filled and the diagnostic is complete, the relay
(electric) or gas valve (gas) energizes providing power to the heating circuit.
Then the control monitors the Ready Thermostat and determines when the
cavity is in “ready” condition.
If the Ready thermostat is at the required temperature and the Home screen
displayed (no cooking mode selected), the heater control cycles the heating
OPERATING PROCEDURE
1. Press the ON/OFF push button. The screen will display a self-diagnostic
screen with progress bar. The drain will close and the steam generating
reservoir will begin filling. When the low probe closes, drain will open until
low probe is open. The drain will close and the steam generating reservoir
fills to high probe until it closes, then the drain will open and the reservoir
drains until high probe is open, then heat will turn on if door is closed.
Unit will continue to drain until low probe opens, then drain will close and
reservoir will fill until the low probe closes. Fill sequence in complete and
the display screen will transition to MANUAL mode and preheating continues
until READY icon turns on (about 10-15).
2. Load food into pans in uniform layers. Pans should be filled to about the
same levels, and should not be mounted.
3. Open the door and slide the pans on to the supports. If you will only be
steaming one pan, put it in the middle position. Some foods will cause foam.
When cooking foods that foam, such as shrimp, put an empty solid 2 ½’
deep pan in the bottom slot of the pan racks.
4. Close the door. When the READY indicator is lit, take one of the following
steps:
• If you want to steam the food for a certain length of time, push the
TIMED button and set the desired time with the TIMER knob. The timer
will automatically run the steamer for the set time and then go into
HOLD. A beeper will sound. Then push “X” button to stop cancel “HOLD”.
• If you want to steam continuously, push MANUAL button. The unit will
continue steaming until stopped.
• Push “X” to stop producing steam.
5. To remove pans from cavity, open the door. Remove the pans from the
steamer, using hot pads or oven mitts to protect your hands from the hot
pans.
6. To shut off the unit, press the ON/OFF push button. The screen will display
a shutdown screen with progress bar. The steam generating reservoir will
begin filling to the high probe until it closes and then drains until the low
probe opens and refills.
NOTE : If a large amount of shrimp is cooked in the steamer, foaming will occur
because the steam lid actually gets so hot that the shrimp will cook on its
surface and the shrimp proteins in the dripping will foam on the surface of the
steam lid. *To avoid this, use a catch pan to catch shrimp drippings and proteins
to prevent foaming when cooking a large amount of shrimp.
TYPICAL QUESTIONS
The following is a sequence of events typical to SmartSteam Pro Boilerless
Steamers.
COOKING FOOD
To use the steamer, ensure the cavity door is closed, press the ON/OFF push
button to on (button light illuminates). The unit verifies the probes and drain
using the following sequence. The drain valve is closed and the water enters the
seam reservoir to the “fill” point. When the water level reaches the LOW level
probe, the water fill valve closes and the drain valve opens until water drops off
the LOW probe. At this point, the drain valve closes and the water valve opens to
refill to the HIGH probe. Drain valve opens allowing water to drop off HIGH probe
and the heater will operate. Water level will continue to drop off the LOW probe.
Drain valve closes and water opens and refills until water reaches LOW probe,
then water fill closes, stopping the entry of water into the steam reservoir.
A relay (electric) or gas valve (gas) energizes and provides power to the heating
circuit for the steam reservoir. This heats the steam reservoir to boil the water-
creating the required steam. When the cavity is heated above 180ºF, the READY
icon comes on with an audible alert indicating that the cooking can start. When
it is desired to cook food in the cavity, the pans are inserted into the cavity and
the door is closed.
Steamer starts in MANUAL mode and heat-up time is about 15 minutes after the
steamer is switched on, if all above conditions are met.
