WARNING: ANY POTENTIAL USEROF THEEQUIPMENT MUSTBE TRAINEDIN SAFEAND
CORRECT OPERATIONG PROCEDURES.
WARNING: WHEN YOU OPEN THE DOOR,STAY AWAY FROM THE STEAM COMING OUT
OF THE UNIT.THE STEAM CAN CAUSE BURNS.
WARNING
AVOID STEAM CONTACT
CONTROLS
Touchscreen Graphic Display
ON/OFF Push Button
Operator controls are on the front right of the unit.
The Groen SmartSteam Pro Boilerless control panel has the touchscreen graphic
display and the ON/OFF push button.
The touchscreen graphic display allows the user to enter and exist the three
cook modes (MANUAL, TIMED and HOLD) and select various settings with
different menus with the controls. The display also provide several audio and/or
visual indicators to the user as cleaning reminders, when the unit reached ready
temperature, hours of operation, error codes, etc.
The ON/OFF button get the Groen SmartSteam Pro Boilerless ready for use or
shuts it off.
COOK MODE OPERATIONS
1. At the home screen or idle mode, the steam generator stay at a low boil or
ready temperature.
2. When the TIMED button is pushed, time can be set by entering the time in
the HH:MM format. The unit steams until the timer counts down to zero and
goes into HOLD mode while timer counts up. At that time the STOP light
illuminates and a beeper sounds.
3. When the MANUAL button is pushed, the unit steams continuously.
4. HOLD mode the steam generator maintains a warming temperature below
the ready temperature.

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 ll/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 ll 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 ow
to the stem reservoir.
When the LOW WATER probe is open, there is a 3 second delay before the water
ll 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 ll valve
is activated.
SERVICE CODES
Error codes are normally cause by probes or timing issues (ll 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 THEDOOR ISOPEN,THE HEATING CIRCUIT WILLNOTBE ENERGIZEDAND
THE HEATING CIRCUIT WILL NOT TURN ON UNTIL THE DOOR IS CLOSED.
After the reservoir is initially lled 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 lling. When the low probe closes, drain will open until
low probe is open. The drain will close and the steam generating reservoir
lls 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 ll 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 lled 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 lling to the high probe until it closes and then drains until the low
probe opens and rells.
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 veries the probes and drain
using the following sequence. The drain valve is closed and the water enters the
seam reservoir to the “ll” point. When the water level reaches the LOW level
probe, the water ll 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
rell 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 rells until water reaches LOW probe,
then water ll 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.

5 SM-GSSP BOILERLESS STEAMER
circuit power relay or gas valve and maintains the ready conditions by cycling
the elements 18 seconds ON, 6 minutes OFF.
If the MANUAL mode is on, the heater control continuously turns on heat to
produce steam.
If HOLD mode is on, the HOLD and READY thermostats operate the control the
heat on the following conditions:
Scenario #1
1. When “HOLD” button is pressed, if HOLD and READY thermostats are
closed then heat will turn on.
2. Heat will remain on until HOLD and READY thermostat opens.
3. When READY thermostat opens, heat turns off.
4. Heat will remain off until READY thermostat closes then heat ON/OFF
cycle rate will initiate.
5. Heat cycle will continue until HOLD “X” is pressed to exit or the unit is
turned off.
6. If the HOLD thermostat closes due to drop in temperature, and the
READY thermostat is still closed, then the heat turns on and sequence
returns to step 2.
Scenario #2
1. When “HOLD” button is pressed, if HOLD thermostat is open and READY
thermostat is closed then heat will turn on.
2. Heat will remain on until READY thermostat opens.
3. When READY thermostat opens, heat turns off.
4. Heat will remain off until READY thermostat closes then heat ON/OFF
cycle rate will initiate.
5. Heat cycle will continue until HOLD “X” is pressed to exit or the unit is
turned off.
6. If the HOLD thermostat closes due to drop in temperature, and the
READY thermostat is still closed, then the heat turns on and sequence
returns to step 2.
Scenario #3
1. When “HOLD” button is pressed or “Timed Cook” mode expires, if HOLD
and READY thermostats are open, then heat will turn off.
2. Heat will remain off until READY thermostat closes.
3. Heat will remain off until READY thermostat closes then heat ON/OFF
cycle rate will initiate.
4. Heat cycle will continue until HOLD “X” is pressed to exit or the unit is
turned off.
5. If the HOLD thermostat closes due to drop in temperature, and the
READY thermostat is still closed, then the heat turns on and sequence
returns to step 2.
A High-Limit thermostat is provided as a safety device on each steam reservoir
to monitor the internal temperature of the steam reservoir. This temperature is
set for 280ºF and will shut down the steamer if there is very little or no water and
the steamer cavity starts to overheat.
DRAINING WATER FROM THE STEAM RESERVOIR
When water or steam is drained from the reservoir, it passes through a water
spray in the drain box controlled by a water solenoid valve to condense the
steam before it exits the steamer drain box into the drain line.
A solenoid drain valve is connected to each steam reservoir. This valve is
normally open, permitting water from the steam reservoir to drain out. When the
unit is turned on, the steam generator drain valve closes and the steam reservoir
starts to ll/drain, and the sequence runs until water reaches the proper level
for cooking operation.
When the unit is turned off, the solenoid valve opens and drains the water from
the steam reservoir. When water is drained from the steam reservoir, it passes
through the drain box and then into the drain line.
When the unit is turned off by the ON/OFF push button, the steamer will ll to the
high probe, drain, rell and drain. This is to remove the heat from the reservoir
for cleaning and reduce any possible cavity warping.
*If hot water is existing, the drain fan thermal switch could close and energize
circuit giving error code 19.
LOW WATER LEVEL DETECTION
Because prolonged operation with less than the required amount of water in the
steam reservoir could present a dangerous situation, the control takes action to
prevent the situation.
If the low probe is satised, the heat turns on and continues operation. If the low
probe is not satised, the control begins to operate unit on the HIGH water level
probe for a period up to a 8 hours maximum.

near non-combustible surfaces, the following minimum clearances are to any
surface, combustible or non-combustible.
Right Side: 2 inches
Left Side: 2 inches
Rear: 6 inches
However, for easy service, at least 6 inch clearance should exist for right side
access to gas shut-off valve.
The unit must be installed in a well-ventilated room with an adequate air supply.
The steamer must be installed beneath a ventilation hood since gas combustion
products exit the appliance.
Any item which might obstruct the ow of air for combustion and ventilation
must be removed. Do not obstruct the ue cover or rear vents after installation.
The area directly around the appliance must be cleared of all combustible
material. The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
National Gas and Propane Installation Code, CAS B149.1.
The unit and its individual shutoff valve must be disconnected from the gas
supply system during any pressure testing of that system which has test
pressures in excess of ½ PSI (3.45kPa). It must be isolated from the gas supply
piping system by closing its individual manual shutoff valve during any pressure
testing of the gas piping system which has test pressures equal to or less than
½ PSI (3.45 kPa).
ELECTRICAL SUPPLY CONNECTION
Provide 115 VAC, 60 HZ, 1 PH, 15 AMP service. Bring wire in through hole on
the back panel. Each cavity requires a separate cord for connection. Local codes

INSTALLATION
NOTICE: THE QUALITY OF THE WATER IS A FACTOR IN THE PROPER PERFORMANCE
OF THE STEAMER. THE WATER SUPPLY SHOULD HAVE A MINIMUM VALUE
OF 30-40 PARTS PER MILLION OF TOTAL DISSOLVED SOLID (TDS).
Many of the problems associated with the degraded performance or non-
operation of the SmartSteam Pro Boilerless Steamer can be traced directly to
improper installation and/or lack of proper and periodic cleaning-all of which is
the responsibility of the customer.
This section is provided to determine that the equipment was installed correctly,
to indicate the proper cleaning techniques ads to be used by Groen customers
and steamer test procedures.
It is to be expressly noted that ALL work associated with the installation and
cleaning of the SmartSteam Pro Boilerless Steamer is NOT covered by the Groen
warranty provisions.
WATER CONNECTION
Make sure that the incoming water connection is made with a ¾” N.H. COLD
water supply hose. Rigid pipe is not required. The water pressure should be
between 30 and 60 PSIG. Higher pressures will require the use of a pressure
regulator. Make sure that all connections are tight with no leaks-no matter how
small.
LEVEL INSTALLATION
It is preferable that the steamer be installed level side to side (left to right) and
slightly pitched (1 to 5 degrees) back to front, with the front always being lower
that the rear. This allows the condensate water to go to the drain at the front of
each cavity.
Make sure that all leg extensions are tight against the oor and that the steamer
is supported on all four legs.
DRAIN LINE INSTALLATION
The drain line should not be less than 1-1/2” – for single units, 2” (5E) – for
double stacked units.
There must be a 2” air gap to the (non-pressurized) building drain. Make sure
that the drain is sloped AWAY and DOWN from the steamer and that there are
no obstructions in the line. Failure to observe these requirements may cause a
water trap in the drain line and produce enough back pressure to prevent proper
cavity draining –resulting in condensate water leaking from the door. Drain line
must NOT be made of plastic pipe. It must be able to withstand boiling water.

PURPOSE
SmartSteam Pro Boilerless Steamers are designed to require only a daily
cleaning of the steamer cavity, pan racks, steam lid and probes to maintain
full performance. Daily cleaning may not be sufcient to control scale build-up,
when a boilerless steamer is operated in a heavy duty, continuous operation in
an area with extreme hard water.
The following procedure outlines steps for optional periodic deliming for
steamers in heavy duty applications and extreme water conditions. The
frequency of the deliming depends upon the severity of the scale build-up and
individual operators.
RECOMMENDED TOOLS & CLEANERS
• Nylon scrub pad, cloth or sponge: Scotch-Brite™ medium duty scrubbing
sponges are preferred. DO NOT use metal scrub pads.
• Delimer/Descaler: Groen Delimer Descaler (PN 114800), Commercial
Lime Away or any equivalent. DO NOT use any cleaning or deliming agent
that contains Citric Acid, any Sulfamic agent or any chloride, including
Hydrochloric Acid.
• Vinegar: Commercial vinegar (5 to 7% strength) has been used successfully
by a number of SmartSteam users as a descaler. Follow the same instructions
as when using delimer/descaler.
CLEANING STEPS
If the “Delime” setting is set to “ON”, the “Delime” button will be available to
initiate the delime process or a manual delime process can be performed by
doing the following:
1. Press ON/OFF push button to turn the steamer off. Open the steamer door.
2. Allow the steamer to shutdown, drain and to cool completely before cleaning.
3. After the steamer has cooled completely, remove the pan and racks.
4. Remove any spilled foods from the steam lid. Remove the steam lid from the
steam reservoir.
5. Press ON/OFF push button to turn the steamer on. Wait for the stem reservoir
to start to ll.
NOTE: Use protective gear, including eye wear for the following steps
involving delimer/descaler.
6. Add delimer/descaler (or vinegar) to the water in the steam reservoir, push
TIMED, and set the timer for 20 minutes. Close the steamer door.
NOTE: ADDITIONAL AMOUNTS OF DELIMER AND LONGER TIME SETTINGS
ARE NOT RECOMMENDED, THEY WILL NOT INCREASE THE EFFICIENCY OF
THE PROCEDURE.
7. When the beeper sounds, press ON/OFF push button to turn the steamer off.
Open the steamer door and wait for the steam reservoir to drain.
8. Press ON/OFF push button to turn the steamer on and wait for the steam
reservoir to again ll with water. Use a nylon scrub pad to remove the
loosened scale.
