General
The STS-200 Steamer/Scale produces steam using
plain tap water for quick steaming of sliced meats.
Simple push button action delivers a consistent impulse
of steam. Because the amount of steam is consistent,
it removes the guesswork and produces a uniform fin-
ished product from one operator to the next.
This manual provides the safety, installation, and oper-
ating procedures for the Steamer/Scale. We recom-
mend that all information contained in this manual be
read prior to installing and operating the unit.
Your Steamer/Scale 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.

Checking and Cleaning the Water Strainer
The Water Strainer protects your equipment from any
foreign debris in the water line that could get into the
food and damage the unit’s solenoid (causing the unit
to leak or flood), It protects from interference with the
equipment’s proper and consistent operation
To ensure proper and consistent steaming results,
check the water pressure regulator gauge and strainer
cup regularly. If the pressure on the gauge has
dropped, check the clear, plastic strainer “cup” and
clean out the accumulated debris as follows.
1. Press the Release Tab and remove the Quick
Disconnect Fitting #2 (Figure 4c). Unscrew the
clear, plastic strainer “cup” and carefully remove
the mesh strainer screen (Figure 4c).
NOTE: Some water may drip out from the Quick
Disconnect fitting and Strainer Cup.
2. At the sink, gently flush all of the accumulated
debris from the strainer cup and mesh strainer.
Be especially careful not to damage the mesh
strainer screen.
3 Carefully place the mesh strainer screen into its
seat at the bottom of the clear, plastic cup and
confirm that the orange O-ring is properly seated
in its place before screwing the strainer cup and
top back together.
4. Reinstall the Quick Disconnect until a “click” is
heard.
5. Cycle the steamer several times. This ensures
the air is purged from the Water Line.
6. Replace damaged or worn parts as needed.
7. Verify that the Water Pressure Regulator Gauge
is set to 7 - 9 PSI (.4 - .6 kg/cm2 or 48 - 62 kPa).
Adjusting the Water Pressure Regulator
The Dual Water Pressure Regulator uses a fixed
regulator and an adjustable regulator (Figure 4c). The
adjustable regulator must be set between 7 - 9 PSI (0.4
- 0.6 kg/cm2 or 48 - 62 kPa). Follow these steps to
adjust this regulator:
1. Make sure that the inlet water valve is on.
2. Over a bucket, press and hold the white plastic tip
on the Quick Disconnect #1 (Figure 4c) until good,
steady water flow is noted (this will purge all air
out of the line). Release and note the pressure
on the Water Pressure Regulator gauge. It should
read 7-9 PSI. If it reads more or less, adjust the
pressure by pulling the black knob upwards and
turning it clockwise to increase or counter-clock-
wise to decrease the water pressure. Push the
knob down to lock it in place.
NOTE: When adjusting the knob, you must relieve
the existing pressure by pressing the white plastic
tip on the Quick Disconnect Insert for 3 seconds.
This allows the newly set pressure to register on
the gauge. Repeat this until the gauge reads 7-9
PSI.
3. Re-install the Quick Disconnect until it “clicks” into
place and test the unit. Re-adjust the regulator as
needed.

OPERATION
Operating Instructions
1. Turn the Rocker Switch (power On/Off) to ON
(Figure 2).
2. Allow the unit to preheat for approximately 30
minutes. The yellow Heater LED, located on the
back of the unit, will illuminate during the time
that the heating element is heating up. When the
unit is ready for operation, the blue Ready light
on the front of the unit will turn on and remain
lit. The unit will display 0.0. If it displays anything
besides 0.0, zero the scale by pressing the “Zero”
button once. If the display still does not read 0.0,
perform the procedures in the “Calibrating the
Steamer Scale” section of this manual.
NOTE: Do NOT press any buttons or use the scale
until it has warmed up and the Blue Ready LED is
ON.
3. Place the sliced meat onto the center of the
Steamer/Scale surface. At the same time, press
the Air Switch (Figure 1). The Steamer/Scale will
initiate a shot of steam.
4. The Blue LED will also turn off for 4 seconds.
This is the timer cycle.
5. Note the weight of the sliced meat and adjust
according to serving requirements.
CAUTION
Handle the Steamer/Scale with great care. Do not
place objects other than sliced meat on the unit
and NEVER place anything over 4 pounds (64
ounces) on the Steamer/Scale. Damage to the
unit may result due to careless handling or mis-
use.
6. When the blue LED turns on, another steam/time
cycle can be initiated.
7. Remove steamed product and complete the
assembly of the sandwich.
Calibrating the Steamer/Scale
If the Steamer/Scale displays anything other than 0.0
during operation, first zero the scale. If the Steamer/
Scale still does not display 0.0 after it has been zeroed,
you must calibrate it as follows:.
1. Turn the unit on and allow it to warm up for 30
minutes.
2. Turn the unit off and wait for 20 seconds.
3. Ensure nothing is on the Steamer/Scale surface
and that the Top Cover is seated correctly.
4. Directly to the right of the Zero (on) button is the
Hidden button used to adjust the scale (Figure 1).
Simultaneously press and hold both the Zero (but-
ton) and the Hidden button and then turn the unit
on. Continue holding the buttons. The system
displays 888, 93, r 1.8, and then rb. At this point,
release both buttons. The unit will then display
C0. If the unit does not display C0, repeats Steps 2
through 4.
5. Press and release the Zero (on) button. Wait for
10 seconds. Do NOT bump the unit, counter,
or touch the Steamer/Scale during this 10
second period! The unit will then display C
and then C1.
6. Place a 1 pound (16 oz.) calibration weight on the
center of the scale surface. Press and release
the Zero (on) button. Wait 10 seconds. Do NOT
bump the unit, counter, or touch the Steamer/
Scale during this 10 seconds! During this 10
second time frame, the unit will display C, don, Sav,
and then 15.9, 16.0, or 16.1.
Remove the 1 pound (16 oz.) calibration weight.
The unit should read 0.0. If it does not, repeat
Steps 2 though 6.
IMPORTANT
Weight readings are accurate at the center of the
scale surface ONLY. Do not weigh sliced meat on
the edges or corners of the Steamer/Scale.
IMPORTANT
Handle the Top Cover with care. If the Top Cover
is bent, dented, or damaged, it may not sit prop-
erly on the Steamer/Scale resulting in inaccurate
weight measurements.

MAINTENANCE (continued)
Weekly Maintenance
The STS-200 Steamer/Scale utilizes an open Steam
Generator. Water sprayed into the Steam Generator surface
flashes into steam immediately, but the minerals in the water
do not steam, they stay on the Steam Generator surface and
accumulate. A small amount of mineral deposits are needed
for proper operation, but a build-up of excessive mineral
deposits causes poor steaming efficiency, excessive moisture
(wet steam) and will eventually severely retard the steaming
action completely.
CLEANING STEAM GENERATOR
1. Perform the Daily Maintenance first.
2. Remove the Top Cover from unit.
3. Remove the Steam Diffuser.
4. Clean Steam Generator free of any product spills.
NOTE: If the mineral deposits come off in “flakes” or in
layers, build-up is excessive.
CAUTION
Use only Arby’s Approved Delimer/Scale Remover when
performing these cleaning procedures. Observe all
instructions, precautions, and warnings on the product
label.
IMPORTANT
Turn the Rocker Switch (power On/Off) to OFF, unplug
the power cord and allow the unit to cool down before
proceeding.
Cleaning the STS-200 Steamer/Scale Daily
1. Check the water quick disconnect fitting and all
hose clamp connections for leakage. If leakage
is apparent, tighten all clamps or replace part if
required.
2. Remove the Top Cover and Diffuser and wash in
a solution of Steam Generator Cleaner (HCS).
Use a wire brush to clean/remove the meat resi-
due from the Top Cover and Diffuser. Rinse in
Sanitizer Solution (HCS) and then with clear
water. Allow to air dry.
3. To clean the Steam Generator, wipe out any meat
and meat juices. Pour some Steam Generator
Cleaner (HCS) into the Steam Generator.
Wait 15 minutes and then use the wire brush to
clean the Steam Generator.
Make sure to remove all meat and meat juices.
Rinse the Steam Generator using Sanitizer
Solution (HCS) and then clear water. If the
Steam Generator is not clean, repeat this step.
4. In this step, the cloths are to be damp, NOT
dripping wet. Clean the Steamer Scale base
using a damp soft cloth and General Detergent
Cleaner (HCS). Rinse using a soft cloth with
Sanitizer Solution (HCS) and then a soft cloth
dampened with clear water.
5. Re-install the Diffuser and Top Cover and plug the
power cord into the appropriate outlet.
6. Turn the Steamer/Scale on, allow the unit to
preheat for 30 minutes, and “zero” it by pressing
“zero” button/switch on the front of the unit
(Figure 8).
7. If the Water Inlet Tube becomes clogged so that
water cannot flow onto the Steam Generator,
refer to the section titled “Cleaning the Water Inlet
Tube” in this document.
IMPORTANT
Turn the Rocker Switch (power On/Off) to OFF, unplug
the unit and allow it to cool down before proceeding.
5. Use a stainless steel wire brush to loosen and
remove excessive deposits from the Steam
Generator surface. Next, reinstall the Steam
Diffuser.
6. Pour Delimer/Scale Remover (HCS) (Arby’s
approved) so that it just covers the top of the
Diffuser. Be sure to follow the delimer manufac-
turer’s directions for proper mixture and use; it
must be safe to be used on aluminum. Wait one
hour.
7. Remove the Delimer/Scale Remover (HCS) from
the Steam Generator and rinse with clear water
to remove all traces of Delimer/Scale Remover
(HCS). Repeat Steps 3 through 7 if needed to
remove mineral deposits.
8. Clean the Cover and Diffuser in a hot solution of
General Detergent Cleaner (HCS) and water,
then rinse in clear water and allow to air dry.
9. Clean unit surface with a hot, clean, damp cloth
(not dripping wet) and wipe dry. Re-install all
parts.
IMPORTANT: To ensure proper steaming characteristics,
some mineral deposits must be present on the Steam
Generator surface. If during cleaning, the surface does
become free of mineral deposits (bare aluminum), add
plain tap water to the surface and allow it to boil off.

Checking/Cleaning the Water Strainer
Monthly
GENERAL
The Water Strainer (Figure 4c) 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 prop-
er and consistent operation.
To ensure proper and consistent steaming results,
visually check the water pressure regulator gauge and
strainer cup regularly. If the pressure on the gauge has
dropped, visually check the clear plastic strainer “cup”
and clean out the accumulated debris as follows.
1. Remove the Quick Disconnect #2 (Figure 4c) from
the incoming water supply or shut off the water
supply valve to the unit. Unscrew the clear plas-
tic strainer “cup” and carefully remove the mesh
strainer screen.
2. Take the strainer cup and mesh strainer to the
sink and gently flush all the accumulated debris
out of them, be especially careful not to damage
the mesh strainer screen.
IMPORTANT: In soft water areas, it may be necessary to
add a small amount of lime to the Steam Generator sur-
face to “season” it.
This will ensure proper steaming characteristics by
producing a thin coating of mineral deposits on the sur-
face. To season the Steam Generator, Mix 1 teaspoon of
Baking Soda with 3 ounces of water.
Pour the seasoning mixture onto hot Steam Generator.
After mixture is converted to steam, the remaining loose
powder can be removed.
10. Plug the power cord into the appropriate outlet
and connect the water line. Turn the Steamer/
Scale on, allow the unit to preheat for 30 minutes,
and “zero” the unit.
11. If the Water Inlet Tube becomes clogged so that
water cannot flow onto the Steam Generator,
refer to the section titled “Cleaning the Water Inlet
Tube” in this document.
Cleaning the Water Inlet Tube
Sometimes when cleaning the Steam Generator, small
particles may be pushed into the Water Inlet Tube caus-
ing it to become clogged.
In a clogged state, the unit is unable to spray water into
the Steam Generator. Follow these steps to clean the
Water Inlet Tube and to restore the unit to proper oper-
ating condition:
1. With the unit heated, insert a straightened paper
clip SLIGHTLY into the Water Inlet Tube opening
(Figure 1) and rotate in a circular motion
NOTE: Do NOT shove the paper clip into the tube,
otherwise you may further clog the tube.
2. After cleaning the Water Inlet Tube, remove the
paper clip and cycle the unit several times to flush
out any particles. If the water sprays, the unit is
ready for use. If the water does NOT spray, follow
Steps 3 through 5.
3. Set the adjustable Water Pressure Regulator
(Figure 4c) between 20-25 PSI.
4. Next, cycle the unit several times to flush out any
particles.
5. Once the water sprays, set the water pressure
back to 7-9 PSI.
NOTE: Cycle the Steamer several times while
adjusting the water pressure regulator knob until
the water pressure gauge reads between 7-9 PSI.
