EO Abator Operation and Installation Manual

EO Abator Operation and Installation Manual

Section 1: Operating Instructions

Operating Instructions for 5XL/8XL and GS Series Steri-Vac Sterilizers

System Description:

1.

Auto-On: The Abator is turned on automatically by the sterilizer.

The 3M EO Abator was designed for use with 3M Steri-Vac Sterilizers and Aerators. The Abator includes all controls and indicators necessary to maintain safe operating conditions within the processing limits of the machine. This system provides an internal operating condition where the EO concentration is well below the lower flammability limit of 30,000 ppm EO in air.

2.

Abator system ready indicator (green) on indicator panel illuminates when the Abator is ready to process EO. With ambient temperature of 21ºC (70ºC), the indicator should illuminate within 40 minutes. If the Abator system ready indicator light does not illuminate within this time frame, observe the fault lights on the control panel and correct problem before operating unit.

3.

End of cycle. The Abator system is stopped automatically by the sterilizer. A timer lets the blower run 30 minutes to cool the Abator before shutting down.

4.

When performing maintenance or when the over temperature indicator is on, the system should be shut down. When shutting down the Abator, make sure the sterilizer is not venting EO and that the Abator is not processing EO. In an emergency situation, the Abator can be shut down at any time. To shut down the system in an emergency, have an authorized person switch the external disconnect and main circuit breaker in the control panel to the off position.

Note: The Abator will be automatically turned on if the power to the Steri-Vac is turned off, or the communication connections between the sterilizer and Abator are lost.

The 3M EO Abator is intended to remove ethylene oxide (EO) from the exhaust of 3M Steri-Vac Sterilizers and Aerators. The EO Abator converts EO into carbon dioxide and water vapor through a heated catalytic process.

The process by which the Abator system works is one in which ambient air is pulled by the blower into the Abator system through the air inlet and pre-filter. The air then passes through the electric heater where it is heated to approximately 138ºC (280ºF). The heated air then passes through the catalytic cell inlet where EO is fed into the air stream through a solenoid valve and injection manifold. As the EO enters the heated air stream, it is diluted with air before it enters the catalytic cell where the EO is catalyzed. The heat given off by this catalytic process raises the temperature of the catalytic cell and the effluent air stream in proportion to the amount of EO introduced into the Abator system. When properly installed with 3M Steri-Vac Sterilizers and/or Aerators, the temperature should not exceed 260ºC (500ºF). If this value is exceeded, damage to the catalytic cell and other internal components will result. The EO Abator achieves at least 99.9% efficiency (time weighted average) in removing EO during sterilization portion of cycle (when EO>100ppm) at normal operating temperatures and concentrations. The EO Abator achieves at least 99.0% efficiency (time weighted average) in removing EO during aeration portion of cycle (when EO<100ppm) at normal operating temperatures and concentrations. The EO Abator should be tested for efficiency on a regular basis as required by local, state or federal regulations.

Typical Abator System Cycle for 5XL/8XL and GS Series Steri-Vac Sterilizers:

After the sterilizer is loaded, the sterilizer door is closed and the cycle is started. The Abator system starts automatically. After approximately 40 minutes, the Abator ready light illuminates indicating the Abator is ready to begin processing EO. When the sterilizer purges EO from the cycle, it enters the Abator through the EO inlet where it is internally fed to the catalytic cell. The temperature of the catalytic cell increases proportionately to the amount of EO fed into the Abator. After the sterilizer cycle is complete and the abatement of EO is halted by the sterilizer, the Abator continues to run for 30 minutes to cool the system down before shutting off. Ambient air flows through the Abator and cools the catalytic cell.

Purchaser’s Responsibility

Select an appropriate site well in advance of purchasing the EO Abator system. Contact your building engineering department for help in selecting a site. It is suggested that the EO Abator system be installed indoors. This saves added installation expense. If this is not possible, the EO Abator system must be installed in a weatherproof enclosure easily accessible by service personnel. This enclosure must be maintained between 0°C to 49°C (32°F to 120°F) at all times. All wiring to and from the control box must be liquid tight until it is indoors. The EO Abator system must be bolted down. Therefore, position the EO Abator system in its proper location and secure it to the floor with 9.53 mm (3/8 in.) diameter bolts or lag screws (minimum 38 mm [1 ½ in.] long) through holes in feet to the floor. To meet seismic requirements, the EO Abator system must be installed using fasteners designed to meet the current local building code or governing jurisdiction. You must have your local architect recommend the proper fasteners. Provide adequate space all around unit for periodic maintenance and service access (see Figure 5).

Only health care professionals, or other appropriately trained personnel in health care and industrial areas, should use this equipment. It is a violation of federal law to use this product in a manner inconsistent with its labeling. Injury to persons or property can result unless the operating instructions are followed carefully.

Securely mount the indicator panel indoors and near the sterilizer in a location that is easily visible by the sterilizer operator. Wiring connections between the EO Abator system, the indicator panel, and the sterilizer are discussed in Electrical Requirements.

It is the purchaser’s responsibility to provide the necessary machine service requirements to the area where the sterilizer and EO Abator system are to be installed. These services include electricity, EO inlet line, safety vent line, and a dedicated exhaust system.

Do not install the EO Abator system in areas where flammable gases or liquids other than EO are present.

Because of varying local codes and labor policies, it is also the responsibility of the purchaser to locate the EO Abator system in its permanent location and to connect the services to the machine. It is the purchaser’s responsibility to ensure that local requirements are met.

EO Abator Efficiency Testing

During the installation and start up process performed by 3M, the EO Abator is tested for electronic function. It is the recommendation of 3M Company that the EO Abator be tested for efficiency on a regular basis as required by local, state or federal regulations by using a gas chromatography method. This method of testing is accepted by most local and state agencies and will provide an efficiency baseline of performance. If independent certification of efficiency is required by state or local authorities or if it is desired by your facility, 3M Company recommends that your facility contact a test lab or company certified by state or local agency. 3M does not perform efficiency testing of the Abator. Return used catalytic cells to 3M Health Care Service Center for proper handling.

Connect corresponding wire numbers between indicator panel terminal strip and the control box terminal strip (see Figures 2, 3, 5, and 6). Use three-pair (6 wire) shielded cables (recommended Belden 18 AWG Part #83656) and limit the length of the wire to 40 M (130 ft.). The shield on the control panel end of the cable must be connected to the ground lug in the control panel. A ground wire from the indicator panel to the EO Abator system is required. If the indicator panel is within 12 M (40 ft.) from the EO Abator system, a 12 AWG ground wire should be used. If the length is 12-24 M (41-80 ft.), a 10 AWG ground wire should be used. For 25-40 M (81-130 ft.) length, an 8 AWG ground wire should be used. In no case is the indicator panel to be mounted more than a maximum of 40 M (130 ft.) away from the EO Abator system. The indicator panel must be located in the sterilizer area. A ground wire from the ground lug in the control panel to earth ground is required. Use the same wire criteria as listed above for the indicator panel to determine the proper wire AWG for the distance run between the control panel and earth ground. Using the DB-15 connector(s) with cable, connect wiring between the sterilizer(s) and the EO Abator system indicator panel (see Figures 2, 3, 5, and 6). Install cable between the EO Abator system indicator panel and the Abator using 6 conductor 18 AWG shielded cable (recommended Belden Part #83656). A 3M service representative will connect the wires to the Abator terminal strip. When connecting only one sterilizer, a jumper wire must be connected from terminal 27 to 25 and from terminal 28 to 26 inside the control box.

EO Inlet Line Requirements – Vent Line from Sterilizer to Abator

A combination of two Steri-Vac gas sterilizers Model 5XL, 8XL, or GS Series sterilizer may be vented through a common vent line to the EO Abator system. Note: The Model 5XL or Model 8XL sterilizers CANNOT be combined with a GS Series sterilizer when connecting to an Abator. Connect the sterilizer vent line to the EO Abator system’s 1.9 cm (3/4 in.) National Pipe Thread (NPT) EO inlet. An adapter may be needed to facilitate the need for a 2.5 cm (1.0 in.) vent line. See Figure 5. The diameter of the vent line used for the EO inlet and safety vent depends on the combined length of the two vent lines. Use 2.5 cm (1 in.) to 3.8 cm (1.5 inch) copper tubing to connect sterilizer discharge to the EO Abator system EO inlet. Refer to table for line sizes. Use a 1.9 cm (3/4 in.) National Pipe Thread (NPT) connection at the EO Abator system. Avoid sags or loops in all lines to prevent moisture buildup at other points in the line. Ensure that the vent line is gas tight

Safety Vent Line Requirements

The EO Abator system is equipped with a safety vent port to vent EO to the atmosphere in the event of an EO Abator system malfunction. Connect a safety vent line to the 1.9 cm (¾ in.) NPT port using properly sized O.D. copper tubing. Install 180º elbow (turned down) with a “bug screen” at the end of the line. Refer to Table 1 for determining proper line size based upon the combined length of both safety vent and EO inlet lines. Note: Adapters may be required. The safety vent line could contain significant amounts of Ethylene Oxide in the event of a system malfunction. Do not terminate the line within 8 M (25 ft.) of any possible sources of ignition or any opening to the building interior such as fresh air inlets, unsealed windows, or pedestrian traffic areas. Keep all of the vent line, with the exception of a turned down extension terminating on the roof top or exterior wall, inside the building. This prevents moisture from freezing in the line and blocking the vent. For additional information refer to the appropriate (XL Series or GS Series) 3M Steri-Vac Sterilizer Site Planning and Installation Guide.

Exhaust System Requirements

The temperature of the air exhaust from the EO Abator can be as high as 260°C (500°F). The EO Abator exhaust can contain low concentrations of EO, typically less than 2.5 PPM. The EO Abator exhaust must be connected to a dedicated exhaust system supplied by the customer. Note: There are two exhaust ducting arrangements that can be used (see Figure 1). Arrangement 1 The EO Abator exhaust is mixed with room air in a negative pressure duct. The advantage of this arrangement is that all leaks are into the duct. The dedicated duct used for the sterilizer hood (if the sterilizer is equipped with a hood) may be used for this arrangement if the ducting and blower is sized to handle the extra 5.66 m3/min (200 ft3/min) of air required for the EO Abator. For 5XL or 8XL, use the information in the 3M Steri-Vac XL Series Site Planning and Installation Manual (78-8078-8490-9) and for the GS Series sterilizers use the information in the 3M Steri-Vac GS Series Site Planning and Installation Guide (78-8083-3481-3) for ducting and blower installation. This arrangement requires an air mixing valve that is attached to the EO Abator exhaust. Air mixing valve (part number 78-8078-9814-9) is available through the 3M Health Care Service Center. Connect the air mixing valve to the EO Abator exhaust flange using high temperature RTV to seal the flanges, then tighten flange clamp (part number 78-8069-7474-3) to lock the parts together. Connect the outlet of the air mixing valve 152 mm (6 in.) O.D. to the duct system with 152 mm (6 in.) metallic ducting (Figures 1 and 8). An airflow damper will be required in the 152 mm (6 in.) duct downstream of the mixing valve to balance the airflow between the EO Abator and the hood duct system. The airflow in the 152 mm (6 in.) duct must be maintained between 5.66-7.08 m3/min (200-250ft3/min) with the EO Abator running and the “abator ready” light illuminated.

Section 4: Figures

The exhaust system is a sealed type which uses the blower in the EO Abator to move the exhaust out of the building. This duct is under positive pressure and must be sealed. It must be dedicated to the EO Abator exhaust only. The suggested ducting to use is Selkirk Metalbestos Model PS in 152 mm (6 in.) size. It must be installed per the manufacturer’s recommendation.

Figure 1

Negative Pressure System – Arrangement 1

The 152 mm (6 in.) Model PS ducting can be used for runs up to 183 meters (600 ft.) long minus 12 meters (40 ft.) for each 90° elbow. The Metalbestos adapter (part number 78-8078-9813-1) is needed to connect the EO Abator exhaust to the Metalbestos ducting, and is available through the 3M Health Care Service Center. Connect the Metalbestos adapter to the EO Abator exhaust using high temperature RTV between the two flanges and then clamp the flanges together with clamp (part number 78-8069-7474-3) to lock the parts together. The termination for either ducting arrangement must not be within 8 meters (25 ft.) of any opening to the building interior such as fresh air inlets, unsealed windows, and/or pedestrian traffic.
