Be sure to follow all safety guidelines contained herein and precautions contained in other relevant product safety literature (i.e., Material Safety Data Sheets) provided with the substances and equipment producing the fumes to be extracted.

Disclaimer
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 personal 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.
Dangers

1. PACE Fume 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, contact 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 or airborne contaminants such as Methyl Ethyl Ketone, 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, fire or explosion.

Warnings

1. Do not attempt to clean any PACE fume extraction filters 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 particles 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 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 & 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 the 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 Cartridge containing 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.

Set up

The Arm-Evac 250 has been designed for ease of use and maximum installation flexibility in mind. 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 three 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.  When positioning the unit, make sure that the exhaust port is not blocked or that airflow from the exhaust port is not restricted in any way.
   ---|---
   Proximity to 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 the flex hose as short as possible.  Do not kink or create any sharp bends in the flex hose, as this will reduce airflow.
   Unit Location| The filtration unit should be positioned so that it will not block aisle ways or impede normal operating traffic of material handling pathways.  It is important to position the unit in such a way that allows for proper clearance to remove the filter access cover and replace the filter as needed.

2. Power
   The Arm-Evac 250 will plug into a standard 110v or 230v 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.
   Caution
   Failure to supply the correct voltage to the unit will result in damage to the motor.

3. Self-Calibration Procedure
   IMPORTANT
   This procedure must be performed on the Arm-Evac 250 before initial operation.

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.

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 Arm-Evac 250 is designed to be used with one to four collection accessories (i.e. flex arm, plenum etc). When using two collection devices, any two may be used together. When using more than two, you must use either 45mm or 50mm Flex Arms and accessories. Performance can only be guaranteed when using genuine PACE Fume Extraction collection accessories. A Silencer/Mobile Cart (8885-1225) is also available.

NOTE
The Arm-Evac 250 can be placed on the benchtop or located under a workbench, depending on operator preference

Self-Calibration Feature

The Arm-Evac 250 contains advanced microprocessor-based sensing technology which allows for selfcalibration of the filter condition monitor by establishing clean airflow conditions (that is, 0% filter blockage) and fully clogged filter flow conditions (that is, 100% filter blockage). Further, this procedure insures that the airflow sensing process is consistent with and particular to the accessory configuration array and filters being used.
NOTE
This procedure must be performed on the Arm-Evac 250 before initial operation, whenever a filter change out 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. Turn the Power Switch (4) on (“I”/”0”) whilst depressing the “Motor On/Off (CALIBRATE)” button on the front touch panel (2). The system will beep once. Continue to hold the “Motor On/Off (CALIBRATE)” button (2) until the system beeps twice. This sequence signals initiation of the self-calibration procedure. The LED lights will sequence from Green to Amber to Red on the Filter Condition Gauge (1) several times. There is no need to adjust the Speed Controller (3); the self-calibration mode over-rides the controller. Note that the Motor Speed LED’s (3) are not illuminated.
2. The Self-Calibration procedure will require a running time of approximately 2 minutes in order to establish clean filter airflow (0% filter blockage) levels for all three speed settings as well as fully clogged filter levels.
3. When the first Green LED (1) remains illuminated and the Motor Speed LED’s (3) illuminate, the self-calibration procedure is complete. To initiate normal operation, depress the “Motor On/Off (calibrate)” button (2) on the front panel until the desired motor speed is achieved.
4. Daily operations can be initiated by simply turning the Power Switch (4) (illuminates Green when on) to the “On” (“I”) position and setting the 3 position speed controller (3) 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 (1) which continuously monitors filter condition. As the system filter(s) collect particulates, LED’s 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 airflow rate decreases (as the filter(s) start to become clogged), LED’s will illuminate high on the graphical display.
Illumination 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 airflow. 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 the display) illuminates, an alarm will sound. Immediately, turn the 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.
Motor Compensation Feature
The Arm-Evac 250 features intelligent pump flow sensors that increase the power to the motor as filters become blocked to assure peak performance.

Maintenance

General Tips:

• Before opening the Arm-Evac 250, always turn off the power source.
• Protect the Arm-Evac and accessories from dampness.
• Do not extract water vapor or steam.
• The Arm-Evac 250 must not be operated without filters. Impurities in the extracted air can damage the motor pump.
