PACE hereby disclaims all responsibility for any personal injury, property damage, fine, citation or penalty imposed by any government or private entity which results from any use, misuse or mis-application of this product, failure of the user to regularly maintain the product according to the recommended guidelines, or failure to adequately monitor fume extraction exhaust air and the ambient workplace air for the presence of harmful levels of gases, fumes and particulates.

Compliance with all applicable environmental and personnel safety regulations is the sole responsibility of the user and adequate self-monitoring of exhaust air released into the atmosphere or the workplace as well as monitoring of the ambient workplace air is strongly recommended. To insure continued effective performance, the following guidelines must be followed.

SAFETY

DANGERS

1. PACE Furne Extractors are not intended to be used as a substitute for devices such as personal protective respirators which are designed to remove poorly adsorbed substances including carbon monoxide, methane, hydrogen, acetylene and other gases. Risk of serious injury or death, fire or explosion may result from improper use. If in doubt, consult with your industrial hygienist or PACE.
2. Never use PACE Fume Extraction Systems to extract fumes from highly flammable liquids and gases such as Ether, Gasoline (Petrol) and others. Risk of serious injury, death, fire or explosion may result.
3. High concentrations of airborne contaminants such as Methyl Ethyl Keytone, Cyclohexone, Ozone and others, when contacted with activated carbon, can undergo oxidation, decomposition or polymerization resulting in exothermic reactions or heat generation. PACE Fume Extraction Systems must not be used to extract fumes from these substances when high concentrations are present.
4. Failure to comply with the application and maintenance guidelines, filter replacement schedules, monitoring recommendations and safety guidelines contained herein and in other relevant product safety literature (i.e., Material ,Safety Data Sheets) provided with the substances and equipment producing the fumes to be extracted could result in risk of serious injury, foe or explosion.

WARNINGS

1. Do not attempt to clean any PACE fume extraction fillers for reuse. Cleaning the filters will severely damage the filter media and, consequently, the filter’s performance. This will result in unfiltered, contaminated air being returned to the working environment. Unfiltered air can also damage the motor pump.
2. Use with inappropriate chemicals or substances, failure to provide regular maintenance or other misuse of your Fume Extraction System may result in contaminated air being recirculated into the work environment.

CAUTIONS

1. Failure to supply the correct voltage to the unit will result in damage to the motor.

NOTES

1. To ensure the highest level of performance, use only PACE replacement filters in your PACE Fume Extraction System.
2. BE SURE the new filter cartridge is installed with the airflow arrow pointing downward.

FILTER CARTRIDGE NOTES
PACE Fume Extraction Systems are equipped with filters designed to capture particulates and noxious gases and odors that are present in the air being filtered. The Fume Extraction systems are equipped with combinations of pre- filters for coarse particle removal, HEPA filters for fine particle removal, and gas filter media to remove gaseous compounds. Over time, the HEPA filter will gradually become clogged, impeding air flow through the system, and the capacity of the gas filter will be reached, reducing its ability to continue to neutralize and adsorb noxious gases and odors.

Filter Cartridges must be replaced at regular intervals to ensure that the fume extraction system is operating effectively. These intervals will vary depending on the type of work being performed, the level of use, and the amount and composition of airborne contaminants produced.
The exhaust air stream from the central filtration unit as well as the ambient air in the workplace should be monitored with appropriate and adequate measuring/detection devices to assure compliance with all applicable Health and Safety regulations.

Flammable vapors and gases (i.e. Isopropyl Alcohol) are removed by and accumulate in the gas portion of the Filter Cartridge presenting a potential fire hazard. Therefore, the user must exercise appropriate precautions when extracting such fumes or when handling and disposing of filters containing such flammable substances.
Follow all fire safety and personnel protection guidelines contained in the Material Safety Data Sheet (MSDS) for the substance(s) producing the extracted vapors and gases (fumes).

When disposing of used filters, extreme care must be taken to comply with all applicable environmental regulations. Carefully consult the MSDS supplied with the material(s) producing the fume. If in doubt, check with your local Environmental Authority.

Extreme care must be exercised when disposing of a used Filter Cartridges containjng potentially hazardous substances. When disposing of filters, appropriate and adequate personal protective equipment (i.e. gloves, respirators, plastic containment bags, etc.) must be used when hazardous substances such as asbestos, lead, radioactive or biohazard materials may be present. Consult the Material Safety Data Sheet (MSDS) of the materials generating the extracted fume.

INSTALLATION

GENERAL
The Ann-Evac 250 and Ann-Evac 200 have been designed with maximum installation flexibility in mind. A number of configurations may be used. (See the “Configurations” section.) The following are recommended guidelines for setting up your system. If you have any specific questions that this section does not cover please consult your PACE Representative or call PACE directly.

1. Placement

There are 3 major considerations that need to be addressed for proper placement of the central filtration unit.

• Exhaust Port: This is located on the back of the filtration unit, next to the power inlet. When positioning the unit, make sure that the exhaust port is 1101 blocked or that airflow from the exhaust port is not restricted in any way.
• Unit Location: The filtration unit should be positioned so that it will not block aisleways or impede normal operating traffic or material handling pathways. [t is important to position the unit to allow for proper clearance to remove the filter access cover and replace the filter as needed.
• Proximity to the work area: The filtration unit should be placed as close to the work area as possible. If using a flex hose, it is advantageous to keep the length of flex hose as short as possible. Do not kink or create any sharp bends in the flex hose, as this will reduce airflow.

2. Power

The Arm-Evac 250/200 will plug into a standard 110 volt or 230 volt electrical outlet, depending on the model you purchased. A line cord is provided with each system. Be sure the unit you have is rated for the intended power supply.

3. Self-Calibration Procedure

4. Filters
Before operating the unit, make sure the filters are correctly positioned. The pre-filter is always located on top, and the direction of airflow is clearly marked on the filter cartridge. Airflow is always in a downward direction for the Arm-Evac 250/200.

5. Inlet Caps
If an inlet port is not connected to a collection device, it must be covered with the inlet cap provided.

6. Accessories

The Ann-Evac 250/200 is designed lo be used with one or two collection accessories (i.e. flex arm, articulated artn, plenum, etc.). ·when using two collection devices, any two may be used together. This provides maximum flexibility in meeting the fume extraction needs in your work environment. Performance can only be guaranteed when using genuine PACE Fume Extraction collection accessories.

CONFIGURATIONS

Connecting the 45mm (1.75’1 and 50mm (2’1 Static-Safe Metal Flex Arms

1. Attach the Static-Safe Metal Flex Arm (either size) at a convenient location on the workbench either permanently or with the bench mounting bracket (PIN 8886-0552).

ARM-EVAC200
As the system is used, the filter will eventually become clogged with collected particulates. If air flow is insufficient to collect the fumes, the filter(s) should be replaced. Refer to “Filter Replacement”, page 12.

1. Turn the power switch to the On (“I”) position.
2. Position the Arm-Evac accessory in a convenient and effective extraction location.

OPERATION

ARM-EVAC 250
Self-Calibration Feature
The Arm-Evac 250 contains advanced microprocessor-based sensing technology which allows for self calibration of the filter condition monitor by establishing clean filter air flow conditions (that is, 0% filter blockage) and fully clogged filter flow conditions (that is, 100% filter blockage). Further, this procedure insures that the air flow sensing process is consistent with and particular to the accessory configuration array and filters being used.

Self-Calibration Procedure

NOTE
This procedure must be performed on the Arm-Evac 250 before initial operation, whenever a filter changeout occurs and whenever a change in system configuration occurs.

DO NOT make any adjustments to the accessory configurations during calibration as this will disrupt the self-calibration process.

1. The normal operating position of the Keyed Switch (item ®) is in a vertical position.
2. TI1e Keyed Switch is supplied with 2 identical keys. To start the self- calibration procedure, insert the key into the switch. Tum the Keyed Switch 1/4 turn clockwise (from nom1al vertical position).
3. Tum the Power Switch (item®) to the On (“l “) position (Green switch light illuminates). An audible single beep followed by a double beep signals initiation of the self-calibration procedure.
   The LED lights will sequence from Green to
   Amber to Red on the Filter Condition Gauge (item ®) several times. There is no need to adjust the 3 position Speed Controller (item CD); the self calibration mode over-rides the controller.

4. The Self-Calibration procedure will require a running time of approximately 2 minutes in order to establishing clean filter air flow (0% filter blockage) levels for all three speed settings as well as fully clogged filter levels.
5. When the far right LED remains illuminated, the self-calibration procedure is complete. To initiate normal operation, turn the Keyed Switch 1/4 tum counter-clockwise. The Red LED will turn off and the Green LED will illuminate and normal operation will resume. Adjust the 3 position Speed Controller (item
6. as necessary. To assure tamperproof operation, the key can be removed from the switch.
7. Daily operations can be initiated by simply turning the Power Switch (illuminates Green when On) to the “On” (” 1 “) position and setting the 3 position Speed Controller (item 0) to the appropriate position. A single beep will sound when the Arm-Evac 250 is turned on.

Arm-Evac 250 Filter Condition Display
The Arm-Evac 250 has a graphical Filter Condition Display which continuously monitors filter condition. As the system filter(s) collect particulates, LEDs on the Filter Condition Display will illuminate along the graphical curve of the display.

Initially, a Green LED will illuminate (at bottom of graph). As the air flow rate decreases (as the filter(s) start to become clogged), LEDs will illuminate high on the graphical curve.
lllumination colors will darken to shades of Yellow and finally to Red as the illumination reaches the top of the graphical curve.

When the first Red LED illuminates, it is indicating insufficient air flow. Replacement of the filter(s) at this point is highly recommended. Refer to “Filter Replacement”, page 12.
If the last Red LED (at the upper right of display) illuminates, an alarm will sound. Immediately, turn system power off (Power Switch) and change filters.

CAUTION
Overheating may occur and cause motor damage if the system is operated with completely clogged filters.

Optional Benchtop Controller for Arm-Evac 250
An optional Benchtop Controller (PIN 8884-2250) is available for the Arm-Evac 250 to enable convenient access to the three speed flow control switch ( refer to item Cg), next page), and surveillance of the filter condition display (refer to item G), next page).

Setup/Operation
Use the following procedure to set up and operate the Remote Control. Refer to illustration below.

1. Attach the end of the Benchtop Controller Cable identified as “250” to the connector located on the back of the Ann-Evac 250 identified as “Remote”. Refer to illustration below.
2. Attach the end of the Benchtop Controller Cable identified as “REM” to the connector located on the Benchtop Controller (item ®).
3. Position the Benchtop Controller i11 convenient location.
4. Once the cables are connected, assume normal operating procedures.

NOTES
Once connected to the Arm-Evac 250, the Benchtop Controller will over-ride all controls with the exception of the keyed calibration switch and Green lighted Power Switch.

If the self-calibration procedure is initiated while the Benchtop Controller is connected, the LED Display on the Benchtop Controller will mimic the filter condition gauge (refer to item CD) as identified in the “Arm-Evac 250 Self- Calibration Procedure”.

Arm-Evac 250 RS232C Output for ISO 14000 Software
The Am1-Evac 250 has a microprocessor integral with its electronic control circuitry which can transfer data to support ISO 14000 documentation requirements. The output connector (marked “PC COMS “) on the back of the Arm- Evac 250 and cable connection provides a corrununication link for transfer and storage of data to a computer.

Contact your local PACE representative or contact PACE directly to obtain detailed operating instructions.
