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 opera-
tion.

• This equipment is to be installed to com-
ply with the basic plumbing code of the
Building Officials and Code Administrators,
Inc. (BOCA) and the Food Service Sanitation
Manual of the Food and Drug Administration
(FDA).
• Water pressure must not exceed 30 psi (2.1
kg/cm2or 207 kPa). Higher water pressures
may cause poor performance, flooding. To
reduce water pressure, install a water pres-
sure regulator and set water pressure to
20 -25 psi (1.4 - 1.7 kg/cm2or 138 - 172 kPa).
• Do not clean this appliance with a water jet.
• Do not use a sanitizing solution or abrasive
materials. The use of these may cause dam-
age to the stainless steel finish.
• To ensure proper steaming characteristics,
some calcium/mineral deposits must be pres-
ent on the generator surface. If, during clean-
ing, the surface does become free of deposits,
add plain tap water to the surface and allow
it to boil off. This will ensure proper steam-
ing characteristics by creating a thin layer of
calcium/mineral deposits on the surface.
• Chlorides or phosphates in cleansing agents
(e.g. bleach, sanitizers, degreasers, or deter-
gents) could cause permanent damage to
stainless steel equipment. The damage is
usually in the form of discoloration, dulling
of metal surface finish, pits, voids, holes or
cracks. This damage is permanent and not

OPERATION
Operator Controls
ROCKER SWITCH (POWER ON/OFF)
When the Rocker Switch (Power On/OFF) is in the ON
position, the Control Board is activated. If the genera-
tor 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 tem-
perature 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 steam genera-
tor surface. 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
steam occurs.
UP DOWN PROGRAM SINGLE SHOT

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.

LOCK LEVER
When in the full forward (towards operator) position,
the lock lever (Figure 8) secures the generator manifold
in position on top of the unit. Moving the lock lever to
the full rearward position unlocks the generator mani-
fold, allowing it to be removed for cleaning or servicing.
NOTE: Do NOT force the lever into position.
HI-LIMIT RESET THERMOSTAT
If the generator overheats for any reason, the Hi-Limit
Thermostat opens (trips) and cuts off power to the
generator. This can be reset by turning the unit off,
unplug the power cord, and allow the unit to cool for 45
minutes. Remove the Main Housing Cover and press
the Hi-Limit’s red reset button (Figure 8). If the Hi-Limit
Thermostat requires continuous resetting, contact your

2002 have an externally resettable Hi-Limit. To
reset it, remove the black protective cap located
underneath the front of the unit and press the but-
ton fully. Reinstall the cap after resetting the unit.
Operating Instructions
1. Turn the unit on and allow it to preheat for approx-
imately 30 minutes.
IMPORTANT: Do not push any of the menu but-
tons during warm-up. The word “LOW” flashes on
the display to indicate the unit is not up to operat-
ing temperature. When the cycle time is displayed,
the unit may be operated.
2. Remove baskets and place desired product into
baskets. Insert baskets into the steamer.
3. Single Shot: Press and release the Single Shot
button and wait 10 seconds for the steam to pen-
etrate the product.

found.
4. When the cycle is complete, remove and empty
the basket(s). At the end of the serving day or
shift, turn off the unit and allow it to cool before
performing the daily Cleaning procedures in the
Maintenance section of this manual.
Steaming Tips
Listed below are some samples of products that have
been tested in the Variety Steamer. Recommended
settings are listed following each product. Refer to
the Programming section of this manual to setup the
steamer for any of these items (results may vary).
Experiment with your products and different steam-
ing times–a little more or less steam could change the
appearance and/or flavor.
Pre-cooked pasta is easily reconstituted, and gives you
a hot product without the wetness of the normal “dip”
method. CYC = 00.20, RATE = 00.05, SHOT = 00.55
If you serve melted cheese on sandwiches, steam is
the perfect way to melt cheese. CYC = 00.10, RATE =
00.05, SHOT = 00.40
A steamed bun (which takes about 10-15 seconds)
says “Hot Sandwich” to your customer. CYC = 00.10,
RATE = 00.05, SHOT = 00.70
Vegetables, rice, and bread products can be reconsti-
tuted by steaming before serving which reduces waste.
CYC = 00.20, RATE = 00.05, SHOT = 00.55
Dinner rolls, muffins, even tortillas can be heated com-
pletely and held without drying out the product.
Use a low plate or pan when steaming to allow
full steam penetration and shorter cooking times.
Condensation inside the steamer is normal, but excess
moisture indicates too much water is being used. See
the Programming and Equipment Setup areas of this
manual.
Heat meat and bread products apart from each other,
then combine in a sandwich. This will keep the meat
juices from soaking the bread. Finish off a special
meal with a steamed hand towel–hot without excessive
moisture.

UP DOWN PROGRAM START/STOP
1 5 : 0 0
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 gen-
erator (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 steam genera-
tor surface. 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 (Shot Interval
Time) should be increased to allow more time for gen-
erator heat recovery, and the SHOT (Steam Shot Time)
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-350 is factory programmed for the following val-
ues 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, settings should
remain as shown above.
To restore the factory settings:
1. Turn the unit off. Press and hold the Program
and Single Shot buttons.
2. Turn the unit on while still holding these buttons.
3. Release the buttons as soon as the unit stops
beeping.
Programming the Unit
NOTE: CYC, RATE, and SHOT are sequential opera-
tions per channel for all programming (you must
perform all steps for CYC and RATE to change
SHOT).
NOTE: CYC, RATE, and SHOT are only displayed
momentarily during the programming sequence
when the PROGRAM button is pressed.

punching tool (such as a paperclip) and fully
insert it through all 18 orifices in the black
manifold as well as through the 10 orifices in
the spray tube. This assures the orifices are
not obstructed with debris. Wash all items in hot,
soapy water. Rinse these items and allow them
to air dry.
5. Reinstall the spray tube into the steam generator
hole and reinstall diffuser plate.
6. Lightly apply some Petrol Gel (included) onto the
large black O-ring and reinstall the O-ring onto
the manifold plate (this allows the manifold plate
to seat easily onto the steam generator). Hold
the manifold plate up to a light source and verify
that light is visible through all the orifices. If so,
seat the manifold fully onto the generator and pull
the locking lever forward to lock the plate.

rectly set to 20 PSI (1.4 Kg/cm2 or 138 kPa).
8. Reinstall all parts and accessories.
Monthly: 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 do not
steam, they stay on the generator surface. A small
amount of calcium/mineral deposits are needed for
proper operation, but a build-up of excessive calcium/
mineral deposits causes poor steaming efficiency,
excessive moisture (wet steam) and will eventually
affect the steaming action completely.
1. Turn the Rocker Switch (power On/Off) to 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 gen-
erator surface (Figure 8). Wipe the generator
with a clean damp cloth. Reassemble the unit.
NOTE: If deposits are still excessive and/or diffi-
cult to remove, see Step 4.

2. Check the rear water quick disconnect fitting and
all hose clamp connections for leakage. If leak-
age is apparent, tighten all clamps or replace
part(s) if required.
3. Remove baskets, top cover housing assembly,
drip tray, and wash in hot, soapy water. Then,
rinse these parts and allow them to air dry.
4. Remove the Black Manifold plate by slightly lifting
and sliding the Locking lever (on the right side
of the unit) towards the rear, carefully remove
the plate and remove the large black O-ring from

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 surface.
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 mix-

PRESSURE RELIEF PLUNGER
The Pressure Relief Plunger (Figure 8) protects the
equipment and user from any harm that can result
if the orifices of the Black Manifold Plate (Figure 8)
has not been cleaned according to the Daily Cleaning
Procedures in this manual. When the orifices become
restricted or clogged, steam pressure buiilds up within
the black manifold plate. This pressure build-up even-
tually forces the Pressure Relief Plunger to elevate
and relieve the pressure, generating a loud “whistling”
sound. If at any time this condition should occur, the
unit must be cleaned according to the Daily Cleaning
Proceduers in this manual. Maintenance procedures
are not covered by warranty.
NOTE: Be sure that the Plunger Relief Valve is
securely mounted to the Plunger Weldment.

Technical Theory of Operation
When the Rocker Switch (power On/Off) is ON, line
voltage flows to the primary side of the step down
transformer. The transformer’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 thermocou-
ple’s DC millivolts.
Once the generator’s temperature approaches the set-
point 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 recommended
setpoints of 375 - 400° F (190 - 204° C), the thermo-
couple generates approximately 7.5 - 8.5 DC millivolts.
The Control Board receives these millivolts and pro-
ceeds to remove the 3-5 VDC to the Solid State Relay
since the heating circuit has now become satisfied.
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 channel buttons can be custom pro-
grammed for cycle time, time between when each
steam shot occurs, and water volume used per each
shot (See the Programming section of this manual). An
audio signal will sound for three seconds at the end of
the cycle.
Two safety devices are incorporated into the VS-350:
• Hi-Limit Thermostat
• Pressure Relief Plunger
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.
If water and or steam pressure builds up beneath the
black Manifold Plate (due to restricted Manifold Plate
orifices), a Pressure Relief Plunger will elevate and vent
the steam pressure above the manifold plate.
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 fed 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 steam-
ing and flooding of the steam generator.
