General
The Variety Steamer produces steam using plain tap
water for quick heating and reconstituting of food items.
Simple push-button action delivers a fully adjustable
impulse of steam. Because the amount of steam is
consistent, it removes the guesswork and produces a
uniform finished product from one operator to the next.
This manual provides the safety, installation, and oper-
ating procedures for the Variety Steamer. We recom-
mend that all information contained in this manual be
read prior to installing and operating the unit.
Your Variety Steamer is manufactured from the finest
materials available and is assembled to Roundup’s
strict quality standards. This unit has been tested at
the factory to ensure dependable trouble-free
operation.

OPERATION
Figure 3. Operator Controls
TIMED CYCLE
The desired timed steaming cycle (up to 99 minutes
and 59 seconds) is selected by pressing and releas-
ing any of the four menu buttons (Figure 3). The main
Control Board applies power to the solenoid at regular
intervals for the duration of the displayed cycle time.
The display counts down to zero when the cycle is
complete, then reverts back to the original programmed
cycle time and the unit is ready for the next cycle.
IMPORTANT: Your steamer is factory programmed
for the following (on each of the 4 menu channels):
 • TotalCycleTime=10seconds[00:10]
(Range: 1 second to 99 minutes and 59 seconds)
 • ShotIntervalRate(RATE)=5seconds[00:05]
(Range: 1 second to 5 minutes and 59 seconds)
 • SteamShotTime(SHOT)=0.70 second [00:70]
(Range: 0.10 second to 2.50 seconds)
This converts approximately 3/4 oz. (25 milliliters)
of water to steam every 5 seconds for a 10 second
steaming cycle. To change any of these settings refer
to the Programming section of this manual.
Operator Controls
POWER SWITCH
When the Power Switch is on, the Control Board
is activated. If the Generator temperature is below
the factory preset setpoint, power is applied to the
Generator until the setpoint temperature is reached.
The Generator is constantly monitored and power is
regulated to maintain the temperature setpoint.
MENU BUTTONS
When any menu button is pressed and released,
power is supplied to the solenoid, the solenoid oper-
ates, and water sprays onto the heated Generator sur-
face. The water flashes immediately into live steam to
heat the product.
One of two operational modes can be used: Single
Shot or Timed Cycle
SINGLE SHOT
The SINGLE SHOT button (Figure 3) is pressed and
released to initiate a single shot. The Control Board
applies power to the solenoid and a single shot of

General Programming
CYC (Total Cycle Time) refers to the total amount of
cooking time set for the product (Figure 4).
RATE (Shot Interval Time) is the time set between
each shot of steam during a complete cycle (Figure 5).
PROGRAMMING
400F
To verify or change the Generator setpoint tempera-
ture, press and hold the UP and DOWN ARROW but-
tons simultaneously for three seconds. Then, raise or
lower the temperature by depressing the UP or DOWN
ARROW buttons. Release the buttons when the
desired temperature is reached.
15:00
To Change the display from Fahrenheit (F) to
Celsius (C), press and hold the UP ARROW and the
PROGRAM buttons simultaneously for three seconds.
Repeat the process to reverse.
15:00
To verify the actual Generator temperature, press and
hold the UP ARROW button. The unit will display the
actual Generator temperature.
Before starting initial programming, there are three
items that should be verified.
* Check/change the setpoint temperature of the
generator (it is recommended that the generator be
set at 375°F (191°C).
* Change the display from Fahrenheit (F) to Celsius
(C) or vice versa.
* Verify the generator temperature after a 30 minute
pre-heat time.
Listed below are the steps to follow for the recommen-
dations listed above.
SHOT (Steam Shot Time) is used to adjust the water
volume used during each solenoid operation (shot of
steam) (Figure 6).
The amount of steam produced by your unit depends
on the amount of water sprayed onto the Generator sur-
face.FloodingoftheGeneratormayoccuriftheSHOT
setting is too high or if the RATE setting is too low.
To prevent this from occurring, the RATE should be
increased to allow more time for Generator heat recov-
ery,andtheSHOTcanbedecreasedtoreducethe
water volume.
Adjustments should be made to both values to deter-
mine the optimum settings for your cooking needs.
Factory Settings
The VS-250 is factory programmed for the following
values for each of the 4 menu channels:
CYC=[00:10]10seconds
(Range: 1 second to 99 minutes 59 seconds)
RATE=[00:05]5seconds(recommended)
(Range: 1 second to 5 minutes 59 seconds)
SHOT=[00:70]0.70seconds(recommended)
(Range: 0.10 second to 2.50 seconds)
These settings deliver approximately 3/4 oz. (25 millili-
ters) of water every 5 seconds for a 10-second cooking
time. Changes may be made to any of these settings.
However,foroptimumperformance,thesettingsshould
remain as shown above.

CLEANING THE STEAM GENERATOR
Your steamer utilizes an open Steam Generator. Water
sprayed onto the Generator surface flashes into steam
immediately, but the minerals in the water stay on the
Generator surface. A small amount of calcium/min-
eral deposits are needed for proper operation, but a
buildup of excessive calcium/mineral deposits causes
poor steaming efficiency and excessive moisture (wet
steam), which will eventually affect the steaming action
completely.
1. Turn the power off, unplug the power cord, and
allow the unit to cool down before proceeding.
 2. PerformtheDailyCleaningprocedures,butdo
NOT reassemble the unit.
3. With the unit cool, use a non-abrasive brass
brush and/or scraper to loosen and remove
the excessive calcium/mineral deposits from
the Generator surface (Figure 8). Wipe the
Generator with a clean damp cloth. Reassemble
the unit.
NOTE: If deposits are still excessive and/or
difficult to remove, see Step 4.
4. Wearing protective eyewear and gloves, pour
delimer solution (not supplied) onto the Generator
surface (Figure 8). Be sure to follow the delimer
manufacturer’s directions for proper mixture and
use.
5. Using a sponge or dry towel, remove the delimer
solution from the Generator. Then, rinse the
Generator with clear water.
CAUTION
If a chemical cleaner/delimer is used, be sure it is
safe to use on cast aluminum. Observe all pre-
cautions and warnings on the product label.
NOTE: To ensure proper steaming characteristics,
some calcium/mineral deposits must be present on
the Generator surface. If, during cleaning, the sur-
face does become free of calcium/mineral depos-
its, add plain tap water to the surface and allow it
to boil off. This may have to be repeated several
times in order to formulate a thin coating of depos-
its. If unsuccessful, see below.
NOTE: In soft water areas, it may be necessary to
add a small amount of lime to the Generator sur-
face to season it. This will ensure proper steam-
ing characteristics by producing a thin coating of
calcium/mineral deposits on the Generator sur-
face. Seasoning mixture consists of 3/4 ounces
(25ml/25cc) of baking soda, 3/4 ounces (25ml/25cc)
of lime and 1 quart (950ml/950cc) of water. Stir
mixture and pour 1/4” deep onto the hot Generator.
After mixture is converted to steam, the remaining
loose powder can be wiped off.
6. Plug power cord into electrical outlet
7. Turn power on and allow the unit 30 minutes to
warm up.
8. Press the SINGLE SHOT button three times to
purge remaining delimer from the Generator.

CHECKING AND CLEANING THE WATER STRAINER
The Water Strainer protects the unit from any foreign
debris in the water line that could get into the food,
damage the unit’s solenoid (causing the unit to leak or
flood), or interfere with the equipment’s proper and con-
sistent operation (Figure 10).
To ensure proper and consistent steaming results,
check the Water Pressure Regulator and Strainer
Cup regularly. If the pressure on the Water Pressure
Regulator has dropped, check the clear plastic Strainer
Cup and clean out the accumulated debris.
1. Shut off the water supply valve to the unit,
unscrew the plastic Strainer Cup, and carefully
remove the mesh Strainer Screen.
2. Take the Strainer Cup and Strainer Screen to
the sink and gently flush out all the accumulated
debris. Be especially careful not to damage the
Strainer Screen.
3. Carefully place the Strainer Screen into its seat at
the bottom of the Strainer Cup and confirm that
the orange O-ring is properly seated in its place
before screwing the Strainer Cup and top back
together.
4. Purge the air out of the strainer and tubing by dis-
connecting the male quick disconnect fitting from
the equipment and, over a bucket, pushing the
white plastic tip in until there is a good water flow.
5. Replace damaged or worn parts as needed.

“OPEN” will be displayed when the thermocouple is open or
not installed correctly. The unit will not call for heat.
OPEN
“TEMP” indicates the control cabinet temperature has
exceeded 155°F (68°C) causing the unit to shut down. If this
occurs, the unit must be turned off for at least 20 minutes so
it can cool off and reset. If this condition occurs again, con-
tact your maintenance person or Authorized Service Agency.
The Control Board monitors the control cabinet ambient tem-
perature and records the highest temperature. Your
service technician could find such information very useful
when troubleshooting the unit.
To determine the control cabinet’s highest temerature since
the last reset:
1. Turn the unit off.
2. Turn the unit back on while pressing both the UP and
DOWN ARROW buttons at the same time.
3. Read the highest control cabinet temperature shown
on the display and release the arrow buttons.
4. Turn the unit off again to preserve this record.

Technical Theory of Operation
When the Power Switch is on, line voltage flows to the
primary side of the step down transformer. The trans-
former’s secondary side supplies 12 and 24 VAC to the
Control Board.
Once powered, and provided that the Generator’s tem-
perature is below the setpoint temperature, the Control
Boardcallsforheatbysupplying3to5VDCtothe
Solid State Relay terminals 3 (+) 4 (-). Once powered,
the Solid State Relay then closes terminals 1 and 2,
which allows line voltage to flow to the Generator.
AstheGeneratorbeginstoheatup,atype“K”thermo-
couple monitors the internal Generator temperature.
As the heat continues to increase, so does the thermo-
couple’sDCmillivolts.
Once the Generator’s temperature approaches the
setpoint temperature, the Control Board begins to pulse
theVDCtotheSolidStateRelay.TheGenerator’s
VAC and AMPS will also pulse during this point. When
the Generator’s temperature is between the recom-
mended setpoints of 375°F─400°F (190°C─204°C), the
thermocouple generates approximately 7.5─8.5DCmil-
livolts. The Control Board receives these millivolts and
proceeds to remove the 3─5VDCtotheSolidState
Relay since the heating circuit has now become satis-
fied.
Then, the Solid State Relay terminals 1 and 2 open up,
and the Generator stops heating. The heating circuit
cycles on and off as needed, even at idle.
When the SINGLE SHOT button is pushed, it signals
the Control Board to initiate a single shot of steam. The
Control Board then supplies 24 VAC to the Solenoid
Valve for a split second. The Solenoid Valve opens and
allows approximately 3/4─1 ounce (4 to 5 tablespoons)
of water to be disbursed onto the Generator surface
for steaming. The water is immediately converted into
steam, which is forced up through the Black Manifold
Orifices to steam the product within the baskets.
Each of the four MENU CHANNEL buttons can be
custom programmed for cycle time, time between when
each steam shot occurs, and water volume used per
each shot (See the Programming section of this manu-
al). An audio signal will sound for three seconds at the
end of the cycle.
If the heating circuit continues to call for heat and the
Generatoroverheats,amanualresettableHi-Limit
Thermostat will trip and open the Generator circuit.
NOTE: If any of these conditions should arise, the
root cause must be determined and corrected. See
the Maintenance section of this manual for further
details.
NOTE: All direct water feed units require a Water
Pressure Regulator. It should be set to 20─25 psi
(1.4─1.7 kg/cm2or 138─172 kPa). Failure to install
a Water Pressure Regulator will result in poor
steaming and flooding of the steam generator.
