OWNER INFORMATION
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 finished product from one operator to the next.
This manual provides the safety, installation, and operating procedures for the Steamer/Scale. We recommend 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 operation.
Warranty Information
Please read the full text of the Limited Warranty in this
manual.
IMPORTANT! Keep these instructions for future reference. If the unit changes owner-
ship, be sure this manual accompanies the equipment.
If the unit arrives damaged, contact the carrier immediately and file a damage claim with them. Save all
packing materials when filing a claim. Freight damage
claims are the responsibility of the purchaser and are
not covered under warranty.
The warranty does not extend to:
• Damages caused in shipment or damage as
result of improper use.
• Installation of electrical service.
• Normal maintenance as outlined in this manual.
• Malfunction resulting from improper maintenance.
• Damage caused by abuse or careless handling.
• Moisture damage to electrical components.
• Damage from tampering with, removal of, or

IMPORTANT SAFETY INFORMATION (continued)
In addition to the warnings and cautions in this manual,
use the following guidelines for safe operation of the
unit.
• Read all instructions before using equipment.
• For your safety, the equipment is furnished with
a properly grounded cord connector. Do not
attempt to defeat the grounded connector.
• Install or locate the equipment only for its intended use as described in this manual. Do not use
corrosive chemicals in this equipment.
• Do not operate this equipment if it has a damaged cord or plug, if it is not working properly, or
if it has been damaged or dropped.
• This equipment should be serviced by qualified
personnel only. Contact the nearest Roundup
authorized service facility for adjustment or repair.
• Do not block or cover any openings on the unit.
• Do not immerse cord or plug in water.
• Keep cord away from heated surfaces.
• Do not allow cord to hang over edge of table or
counter.
The following warnings and cautions appear
throughout this manual and should be carefully
observed.
• Turn the unit off, disconnect the power source
and allow unit to cool down before performing
any service or maintenance on the unit.
• The equipment should be grounded according to local electrical codes to prevent the
possibility of electrical shock. It requires a
grounded receptacle with separate electrical
lines, protected by fuses or circuit breaker of
the proper rating.
• All electrical connections must be in accordance with local electrical codes and any
other applicable codes.
• WARNING ELECTRICAL SHOCK HAZARD.
FAILURE TO FOLLOW THESE INSTRUCTIONS
COULD RESULT IN SERIOUS INJURY OR
DEATH.
- Electrical ground is required on this appliance.
- Do not modify the power supply cord plug.
If it does not fit the outlet, have a proper
outlet installed by a qualified electrician.
- Do not use an extension cord with this
appliance.
- Check with a qualified electrician if you
are in doubt as to whether the appliance is
properly grounded.
• This equipment is to be installed to comply 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).
• If the supply cord is damaged, it must be
replaced by the manufacturer or its service
agent, or a similarly qualified person.
• Do not clean this appliance with a water jet.
• Do not use a sanitizing solution or abrasive
materials. The use of these may cause damage to the stainless steel finish.
• To ensure proper steaming characteristics,
some mineral deposits must be present on
generator surface. If, during cleaning, the
surface does become free of mineral deposits, one approved method is to add plain tap
water to the generator surface and allow it
to boil off. This will ensure proper steaming
characteristics by creating a thin layer of mineral deposits on the casting.
• Chlorides or phosphates in cleansing agents
(e.g. bleach, sanitizers, degreasers or detergents) 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
covered by warranty.
NOTE: This may require repeating several times.

When mounting the Dual Water Pressure Regulator
onto a fixed horizontal or vertical surface, you must
use the mounting screws provided with the kit. These
screws are self-tapping and require a 0.125” inch hole
for mounting.
A free-standing mounting does not require use of the
mounting screws.
WARNING
DO NOT mount the Dual Water Pressure Regulator
over an electrical outlet or any other appliance or
area that may be damaged by water or that may
cause personal injury.

INSTALLATION (continued)
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-clockwise 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.

Installation
The optional Water Installation Kit is used in conjunction with the Dual Water Pressure Regulator for the
STS-200.
It allows you to easily connect your existing water supply to the STS-200 Steamer/Scale. It is equipped with
quick disconnect attachments for easy installation and
also has a water shut-off valve for maintenance
(Figure 5).
To install, follow these steps:
1. Make sure that the Water Shut-off Valve is
closed.
2. Attach the T-Fitting to your existing water supply.
NOTE: The T-Fitting is for 1/4” O.D. Tubing
3. Attach the Quick Disconnect fitting to the inlet
connection of the Dual Water Pressure Regulator.
WARNING
Make sure that the water hoses are not kinked or
bent. This could result in poor steaming performance.
