Site Planning and Installation Guide
I. Introduction (continued)
Plan and Install
Site planning is a critical aspect for a successful
installation process. Site planning includes
considerations for: the location, the work flow,
the 3M™Steri-Vac™Sterilizer/Aerator GS Series
service requirements, 3M™Steri-Gas™EO Gas
Cartridge storage requirements both near the GS
Series sterilizer and storage for larger volumes, any
connected hardware such as the 3M™Abator,
3M™Stacking Rack 1237, ventilation apparatuses,
and local code requirements. The purchaser must
comply with all state and local regulations affecting
the use of ethylene oxide (EO). It is important
to have a properly planned and acceptably
prepared site to ensure the GS Series sterilizer
operates safely and effectively. All site planning
and preparation must be completed prior to the
scheduled installation date.
The following describes the tasks for planning and preparing for a successful installation. While each
installation site is unique, the following steps are common to all situations:
Step 1 Select the Equipment
3M offers a complete system of products for ethylene oxide (EO) sterilization, including two sizes of
3M™Steri-Vac™Sterilizer/Aerator GS Series. Both sizes are available in single door or double door
configurations. Use the 3M™Abator, where applicable, for efficient abatement of exhausted EO and for
using supporting accessory equipment. Selecting the size, quantity and configuration of the GS Series
sterilizer and the number of 3M™Abators is the first equipment selection task. Second, select any
required auxiliary equipment. Additional detailed equipment technical specification information for the
products is available from 3M. Use Table 1 on the following page to document selected equipment.
Step 2 Select a Location
Step 2 recommends a process for analyzing a site and for selecting a suitable location for installing the
Sterilizer/Aerator system. This Guide includes sample proposed site plans, with architectural details,
for a satisfactory site design. It also includes information on how to design the site. Site Planning and
Equipment Location Worksheets are provided in ANNEX B.
Step 3 Prepare the Area and Service Requirements
Critical service requirements must be met before completing and approving the 3M™Steri-Vac™
Sterilizer/Aerator GS Series Site Readiness Verification Form. These requirements include acceptable
room ventilation, connections to electrical power, connections to vent lines, and compressed air lines.
Service requirements are detailed in Section III.
The purchaser is responsible for securing and scheduling all contracted services in order to meet
installation requirements and for supplying details of the service requirements to the contractors.
The final installation support visit will not be scheduled until all equipment installation requirements
have been met, verified, and documented on the Site Readiness Verification Form found in ANNEX C.
Sections II and III provide information detailing service specifications and requirements. ANNEX B
provides Site Planning and Equipment Location Worksheets. This information can be reproduced
and provided to service contractors, as necessary, to complete the required pre-installation work.
Deviations from the Site Plan:
The purchaser should document any deviations from the recommended 3M Site Planning guidance
and communicate the deviations to 3M Health Care service personnel or authorized 3M service
personnel prior to installation.
Step 4 Install the Equipment
Final equipment hook-up and installation support is performed by 3M Health Care service personnel
or authorized 3M service personnel. A final Installation Verification Form is completed at the end of
equipment installation.

DANGER
To reduce the risks associated with
exposure to ethylene oxide, ensure
compressed air supply is clean, with a maximum
allowable dirt particle size of 0.5 microns, and
oil-free. Ensure air filters on compressed air
supply contain a water trap and are cleaned
and maintained properly.
Compressed Air Requirements
Compressed air is used to operate a venturi vacuum generator and to operate the air-controlled pistons
that both lock and unlock the 3M™Steri-Vac™Sterilizer/Aerator GS Series door. Table 4 provides
the compressed air requirements. The vacuum operates during the sterilization cycle to remove air
and ethylene oxide (EO) from the GS Series sterilizer chamber. The vacuum also operates during the
Aeration stage, which may last in excess of 12 hours.
Moisture in the compressed air line will not be removed by the supplied filter. A refrigerated air dryer
may be needed to meet the dew point requirement in Table 4 and should be a non-cycling hermetic
type compatible with the flow and pressure of the selected compressor. The air dryer should be
capable of accepting saturated air and drying it to 10°C (50°F) dew point at 38°C (100°F) ambient.
The air dryer would typically have an automatic drain trap and be wired from the compressor controller.

Site Planning and Installation Guide
Filters
A 3M air line filter kit is needed and supplied with each 3M™Steri-Vac™Sterilizer/Aerator GS Series to
remove dirt and mist particles from the incoming air. This filter must be installed on the compressed
air line at the time of equipment installation and must be drained periodically by the purchaser in order
to remove excess water. These filters are replaced at each recommended six month preventative
maintenance service procedure.
The installation includes installing the 0.3 micron filter element (mist separator) in front of the
0.1 micron filter element (micro mist separator) in order to remove coarse air contaminants that would
otherwise plug the micro-mist element. The elements may need to be changed more frequently than
six month intervals if the air supply is highly contaminated.
The purchaser is solely responsible for providing a dry, oil-free air supply (to a dew point of10°C/50°F).
Filters are provided for precautionary purposes only, and not as a replacement for a clean air supply.
A contaminated air supply can quickly reduce the effectiveness of the filter element, resulting in early
equipment failure.
Multiple Sterilizer/Aerator Installations
Each 3M Steri-Vac GS Series sterilizer requires a minimum flow rate of 2.2 liters per second
(4.7 scfm) at 5.6 kg/cm2(80 psig) pressure. Two sterilizers would require a flow rate of
4.4 liters per second (9.4 scfm) air flow at 5.6 kg/cm2(80 psig).
Compressed Air Line Installation Kit
The Compressed Air Line Installation Kit, supplied with each GS Series sterilizer, is installed between
the sterilizer and the compressed air services as shown in Figure 9. The purchaser is responsible for
providing compressed air services.
Compressor Location
The compressor should be located away from work areas in order to reduce noise levels around the
GS Series sterilizer. Make sure the compressor manufacturer’s electrical power requirements are met.

Ethylene Oxide Vent Line Requirements
DANGER
To reduce the risks associated with
exposure to ethylene oxide:
a connection must be made from the
3M™Steri-Vac™Sterilizer/Aerator GS Series to a
dedicated vent line to exhaust ethylene oxide (EO)
to the outside atmosphere or to the 3M™Abator
emission control system.
ensure the vent line is gas tight from the GS Series
sterilizer to the outside atmosphere.
do not terminate vent line into exhaust system that
recirculates air into the building.
the vent line should terminate away from areas
where people walk or work. The vent line should
be located at least 7.6 m (25 ft) away from the
building air intake source.
vent line must be labeled to indicate EO.
ensure no blockages in vent line exist.
ensure the instructions detailed in this Guide are
followed when planning and installing the ethylene
oxide vent line.
A connection must be made from the 3M™Steri-Vac™Sterilizer/Aerator GS Series to a dedicated vent
line in order to exhaust ethylene oxide (EO) to the outside atmosphere or to the 3M™Abator emission
control system. The requirements for venting the GS Series sterilizer must be met (Table 5).

The 3M EO Abator can be used with the GS Series sterilizer with a maximum of two GS Series
sterilizers and up to a maximum of two 3M Aerator models XL or XLS connected to a single EO Abator
unit. Sterilizer models 5XL and 8XL cannot be combined with a GS Series sterilizer when connecting to
an EO Abator. The EO Abator interfaces with GS Series sterilizers to start and stop automatically.
The diameter of the vent line used for the EO inlet and safety vent depends on the combined length of
the two vent lines. The size of the copper tubing to connect sterilizer discharge to the EO Abator system
EO inlet should be between 2.5 cm (1.0 in) and 3.8 cm (1.5 in). The size of the National Pipe Thread
(NPT) connection at the EO Abator system should be 1.9 cm (3/4 in.). Reference Table 5 for required
line diameters.
The maximum length of the vent line from the GS Series sterilizer port is 91.5 meters (300 feet).
Do not exceed this specification. The use of Type K hard drawn copper tubing is recommended.
The vent system should be constructed of straight lengths of copper tubing using a minimum number
of long radius elbows. Short radius elbows and T fittings cause an excessive amount of back pressure
and should not be used. Include a threaded fitting to termination of the run with which to facilitate the
pressure test of the system.
The vent line should be designed to avoid sags or loops in order to prevent moisture buildup at other
points within the vent line. The vent line must be gas tight from the sterilizer to the outside atmosphere
and be brazed or soldered in accordance with local fire codes.
The vent line, with the exception of a turned-down extension terminating on the roof top or exterior wall,
should be inside the building in order to prevent moisture from freezing in the vent line and blocking the
vent (Figures 10, 11 and 12).
3M Abator (Emission Control Devices)
3M Abators (Models 50AN, 50AE or 50AJ) can be connected to and are compatible with the
3M Steri-Vac Sterilizer/Aerator GS Series. Consult the 3M Abator Operation and Installation Manual
for further information.

Vent Line Labeling and Install Considerations
The vent line contains significant amounts of EO during the Gas Removal and Flushing stages. Ensure
the vent line is gas tight from the GS Series sterilizer to the outside atmosphere and is labeled to
indicate EO. A separate vent line to the outside is required. The vent line should terminate away from
areas where people walk or work and should be located at least 7.6 m (25 ft) away from the building
air intake source.1
Do not terminate the vent line within 7.6 m (25 ft) of any possible source of ignition or any opening to
the building interior such as fresh air inlets, unsealed windows, or pedestrian traffic areas. The inlet
assembly, from the Vent Line Installation Kit, must be installed within 91.44 cm (3 ft) of the
sterilizer's EO port in a position that is accessible to 3M Health Care service personnel (Figure 10).
The single vent line is run directly to the exterior or to the 3M Abator using the appropriate connection
fittings. When the 3M Abator is installed, run the vent line from the vent outlet port on the 3M Abator
to the outside. Shut off valves in the vent line are not recommended.
