3M Versaflo TR-600 Series, TR-6710N-5, TR-6710N-40 Manual

System Description

The 3M™ Versaflo™ Powered Air Purifying Respirator (PAPR) TR-600 Assemblies are part of the 3M™ Versaflo™ Family of respiratory protection products. The TR-600 PAPR assemblies are designed to be used with the 3M headgear listed on the approval label to form a complete National Institute of Occupational Safety and Health (NIOSH) approved respiratory system. When used in accordance with its NIOSH approval, TR-600 PAPR assemblies help provide respiratory protection against certain gases, vapors and particulates. 3M™ Versaflo™ systems and components are for professional occupational use only. The TR-600 is not an intrinsically safe system. See the "NIOSH Approval" section in these User Instructions for additional information regarding approvals.
The TR-600 belt mounted assemblies consist of a motor/blower unit, high efficiency (HE) particulate filter or combination chemical cartridge/HE filter, lithium-ion battery pack, and waist belt. The motor/blower unit draws ambient air through its filter/cartridge and supplies filtered air to the headgear via a breathing tube. For ease of use and training, most user interface points are colored blue. The blower provides three user selectable airflow settings. It is equipped with automatic flow control; the motor airflow is regulated during operation to compensate for the charge state of the battery, the increasing level of airflow resistance caused by particle filter loading, and changes in air density due to changes in elevation and air temperature. Should the airflow fall below the minimum design flow rate, an audible alarm and vibratory alarm will activate and the filter loading LED on the blower unit will flash red to warn the user to immediately leave the contaminated environment. Similarly, an audible, vibratory and visual low battery alarm will activate when the battery pack has approximately 10-15 minutes of charge remaining to warn the user to leave the contaminated area.
Multiple cartridges are available for specific chemicals, grouping of chemicals, and chemical families. The effective use time (service life) of the cartridge will vary depending on your specific environment. Under the Occupational Safety and Health Administration (OSHA) Respiratory Protection Standard (U.S. 29 CFR 1910.134), it is the employer's responsibility to ensure adequate worker protection including selecting the appropriate filter/cartridge for this PAPR system, and ensuring the cartridge is used within its service life. 3M provides free software to aid in filter/cartridge selection and service life calculations available at www.3m.com/workersafety.

• Battery packs should be charged immediately and fully upon receipt.
• Read and understand the contents of these User Instructions prior to use, including all warnings and advisories.
• This system is for professional occupational use only.
• The filter loading indicator is for particulate only. It does not convey any information about gas and vapor service life.
• The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 System is not designed or approved to meet intrinsic safety standards.

At a minimum, each NIOSH approved configuration of this PAPR system should include approved headgear or facepiece, breathing tube, motor/blower, filter/cartridge, battery, and a belt or backpack. Common accessories include prefilter/spark arrestor and filter cover. Refer to the supplied User Instructions for each of these components for additional information prior to use.

High Efficiency (HE) Particulate Filter, Chemical Cartridge/Filter, Prefilter, Spark Arrestor and Filter Covers

Always correctly use and maintain the filter/cartridge assembly. Failure to do so may reduce respirator performance, overexpose you to contaminants, and may result in sickness or death.

1. Inspect filter/cartridge and inner circular sealing gasket before each installation. Replace filter/cartridge if damaged or if the circular gasket is damaged or missing.
2. Always properly install the filter/cartridge into the blower unit.
3. Keep inner circular sealing gasket clean.
4. Never attempt to clean filters by knocking or blowing out accumulated material. Doing so will damage the filter media.
5. Use of the spark arrestor is mandatory for welding and all situations where the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 may be exposed to sparks, molten metal or other hot particulates. Failure to use the spark arrestor when needed may allow the filter to catch fire, or be damaged and allow contaminants to enter the respirator and may result in injury, sickness or death.
6. Store the filter as described in these User Instructions within the recommended storage temperature conditions and observe filter expiration dates.
7. The filter loading indicator is for particulate loading levels only. It does not provide any information about gas and vapor service life. Attempting to use the filter loading indicator for gases and vapors may result in sickness or death.

The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 can be used with either a high efficiency (HE) filter or combination chemical cartridge/HE filter. The available filter and filter/cartridge options can be found at www.3M.com/workersafety or in the TR-600 Components, Accessories and Replacement Parts guide.

Particulate Filter Loading

The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Motor/Blower has a combination HE filter loading/low airflow indicator (Fig. 14-5). This indicator is for particulate loading only; it does not apply to the service life of the carbon in the chemical cartridge for the combination HE filter/gas and vapor cartridges. With a new HE only filter, all LEDs on the indicator will light green. For certain combination HE filter/gas and vapor cartridges the inherent pressure drop, even on a new cartridge/filter, may prevent the top LED on the filter loading indicator from being lit. As the HE filter becomes loaded, the LEDs will begin to turn off. User must immediately leave the work area and the filter should be changed when the audible alarm or a red LED activates or when the chemical cartridge service life is exceeded – whichever comes first. See the "Operating Instructions" section of these User Instructions for further information on the HE filter/low airflow alarm.

Gas and Vapor Cartridge Service Life

The effective use time (service life) of a chemical cartridge (gas and vapor cartridge) will vary depending on your specific environment. The user must determine a service life period based on their specific work conditions. The 3M™ Service Life Software (www.3m.com/workersafety) may be able to assist user in this calculation.

Prefilter/Spark Arrestor

Use of the foam prefilter (3M™ Prefilter TR-6600) and metal mesh spark arrestor/prefilter (3M™ Spark Arrestor TR-662) is optional in many situations. They can be used individually or in combination. Both act by helping to block larger particles from reaching the main filter, and if changed (TR-6600) or cleaned (TR-662) frequently may help to extend the useable life of the main filter. The spark arrestor may be cleaned by rinsing it under water. NOTE: Use of the spark arrestor is mandatory for welding and all situations where the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 may be exposed to sparks, molten metal or other hot particulates. Failure to use the spark arrestor when needed may allow the filter to catch fire, or be damaged and allow contaminants to enter the respirator and may result in injury, sickness or death. The foam prefilter and the metal mesh spark arrestor must be used with a filter cover.

Filter Covers

Filter covers are available for each size of filter. Use of filter covers are highly recommended. Filter covers help protect the filter body and filter media from damage from external forces. The filter cover must be in place if operating the PAPR in a decon shower or while being subject to liquid spray. The filter cover helps the PAPR resist water spray directed towards the wearer, such as if going through a decon shower. The filter cover is required when using a prefilter or spark arrestor prefilter.

Install and remove HE filter, filter/cartridge, prefilter, spark arrestor and cover

Install and remove the filter/cartridge in non-hazardous locations only.

1. Inspect the filter/cartridge to be installed:
   • Filter/cartridge is intact with no tears, cracks, distortion or other damage.
   • The inner circular gasket is present and intact with no tears, cuts or distortions. Wipe the filter seal with a clean cloth if necessary. Dispose of and replace filter/cartridge if damage is noted or suspected. NOTE: The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600/TR-800 Filter/Cartridge Assemblies have both an inner circular gasket (Fig. 3-6) and outer rectangular barrier (Fig. 3-5). The inner gasket is the primary seal between the filter and blower. The outer barrier acts to keep dirt and debris from behind the filter.

• Press and hold the smaller, blue power button (Fig. 13-1) for 1 second. The unit will turn on and perform a self-diagnostic. The flow level, filter loading and battery charge indicators will blink, the auditory alarm will sound and vibratory alarm will activate. Battery indicator (Fig. 13-4) will show current charge status of the battery pack. Filter indicator will show remaining capacity of the filter (Fig. 13-5). Continuous blinking and/or sounding of any alarm indicates a fault condition that must be corrected prior to use of the respirator system. If auditory, vibratory alarm or visual indicators do not activate at start-up, do not use system. Remove from service and see your supervisor.
  
  1. On/Off button,
  2. Flow control button,
  3. Airflow setting indicator,
  4. Battery charge status level/alarm indicator,
  5. Filter loading/alarm indicator,
  6. Tight-fitting mode indicator (future option)

Select airflow:

• There are three user selectable airflow settings – standard, medium, and high flow. The motor/blower will start at the standard flow setting. Pressing and holding the larger blue flow control button (Fig. 132) for 1 second will cycle the motor/blower to the next of three flow settings. One beep and flow LED on the flow setting indicator (Fig. 13-3) indicates standard flow, two beeps and two flow LEDs indicate medium flow, three beeps and three flow LEDs indicate high flow. Pressing the flow control button once more cycles back to the standard flow setting.

Power 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 off:

• Press and hold the smaller, blue power button for 2 seconds (Fig. 13-1).

Display Sleep Mode

To conserve battery power, the display will go into 'sleep mode' after 30 seconds from the last button press. The flow speed indicator will periodically blink with the current flow setting (Fig. 13-3). To wake up the display, momentarily press any display button.

Battery Charge Status Indicator and Low Battery Alarm

The battery level/alarm indicator (Fig. 13-4) displays the remaining battery charge status. This charge status indicator mirrors the charge status indicator on the battery. The number of bars illuminated indicates approximate battery pack charge status remaining: 5 bars = 80-100%, 4 bars = 60-80%, 3 bars = 40-60%, 2 bars = 20-40%, 1 bar = < 20%, 1 bar flashing = < 10%. The charge status indicator is based on the original charge capacity. It does not recalibrate as the battery ages, and the number of bars illuminated with a fully charged battery will decrease as the battery naturally loses capacity. This is a safety feature so that throughout the life of the battery the number of charge status bars lit consistently indicates approximate run time remaining (with a given system setup and filter loading). When the low battery alarm sounds, users must immediately exit the hazardous area and replace the battery.

Filter Load Indicator and Low Flow Alarm

The filter loading indicator (Fig. 13-5) monitors the pressure drop in the system. Increase loading of contaminants on the filter is indicated by the progressive extinguishing of LEDs in the filter loading indicator. As the pressure drop increases the motor/blower fan speed increases to compensate. When the fan is no longer able to compensate and provide adequate airflow, the motor/blower will alarm. A low flow alarm is indicated by the bottom LED of the filter loading indicator flashing RED. When the low flow alarm sounds, users must immediately exit the hazardous area and replace the filter/cartridge and/or the prefilter/spark arrestor.

INSPECTION

Failure to follow these User Instructions may reduce respirator performance, overexpose you to contaminants, and may result in injury, sickness, or death.

1. Do not use with parts or accessories other than those manufactured by 3M as described in these User Instructions or on the NIOSH approval label for this respirator.
2. The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 assembly is one component of an approved respiratory protection system. Always read and follow all User Instructions supplied with your 3M headgear and other system components in order to ensure correct system operation.
3. Do not turn off the motor/blower, remove the facepiece or headgear, or reach your hand into the headgear while inside the contaminated area. This could allow contaminants to enter the respirator and may result in sickness or death.

Before each entry into a contaminated area, the following inspection must be performed to help ensure proper function of the respirator system. Respirator systems are intended to help reduce exposures to certain contaminants and should always be handled with care and fully inspected prior to use. Refer to the specific assembly subsection of these User Instructions for proper assembly procedures.

1. PAPR system:
   • Closely inspect the entire PAPR system including the motor/blower, cover, filter/cartridge, breathing tube, battery, belt, headgear. Pay particular attention to component connection points for wear or damage. If parts are missing or damaged, replace them only with 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 replacement parts before proceeding.
2. Filter/cartridge:
   • Closely inspect filter/cartridge plastic housing including the corners and latches, outer rectangular barrier, and inner circular filter seal gasket for cracks, tears, cuts, distortion, indentations or debris. Replace filter/cartridge if damaged. If the filter/cartridge has been mishandled or dropped, reinspect fully. If you have any concerns, contact 3M Technical Service for guidance.
   • Ensure the filter/cartridge is properly installed in the PAPR unit.
   • If the filter cover is used, the filter/cartridge label must be visible in the filter cover window (Fig. 14).
     
   • If sparks or other hot particles are present, the spark arrestor with filter cover must be in place in front of the filter/cartridge and prefilter (if used). Failure to use the spark arrestor when needed may allow the filter to catch fire, or be damaged and allow contaminants to enter the respirator, and may result in injury, sickness, or death.
3. Battery pack: Confirm that the battery pack is fully charged or charge is sufficient for duration of the work period. Ensure plastic surrounding electrical contact pins are intact. The battery pack must be latched to the motor/blower. Gently tug on the battery to ensure secure connection.
4. Breathing tube: Examine the entire breathing tube for tears, holes or cracks. Bend the tube to verify that it is flexible. Ensure the gaskets located at both ends of the breathing tube (i.e. headgear and air source connections) are present and not damaged. The breathing tube should fit securely into the air source connection.
5. Headgear: Follow the User Instructions supplied with your 3M headgear to ensure correct system operation.
6. Airflow check:
   The TR-600 is pre-calibrated to ensure required airflow. However, the 3M™ Airflow Indicator TR971 must be used to verify minimum required airflow is attained prior to each day's use. The TR-600 compensates for changes in air density, which is affected by elevation and air temperature. During use, if you suspect the TR-600 is not delivering a minimum of 6 cfm (170 lpm), exit the contaminated area, see your supervisor, and recheck the airflow with the 3M™ Airflow Indicator TR-971. The airflow is checked with your current filter installed.
   • Ensure float ball in the TR-971 moves freely in the tube and the gasket at the bottom end of the tube is in place.
   • Insert the TR-971 into the outlet of the TR-600 motor/blower unit. If the breathing tube is in place, it must be removed to allow the airflow indictor to be inserted (Fig. 15-1).
     
   • Turn the motor/blower unit on by pressing and holding the power button for 1 second. Run the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 for up to 1 minute to allow the airflow to stabilize.
   • With the airflow indicator in a vertical position, ensure that the bottom of the floating ball rests at, or above, the minimum flow mark for the 'letter' representing your 'Zone' (Fig. 15-2). Airflow indicator must be in the vertical position for an accurate reading.
     
     The airflow indicator is graduated into different 'zones' based on air density, which is based on elevation and ambient temperature. To determine your zone, determine the elevation and temperature for the environment where you are conducting the airflow check. See your supervisor if you are not certain of these values. Find the zone where your elevation and temperature intersect on the chart supplied with the airflow indicator (Chart 1). For additional guidance on conducting an airflow check, consult 3M Technical Data Bulletin #221 Conducting Airflow Check on the TR600 or contact 3M Technical Service.
     
     Recommended use temperature range: 23°F to 131°F (-5°C to 55°C). Recommended elevation: -328 feet to 16404 feet (-100 meters to 5000 meters). Contact 3M Technical Service if intended use may be outside of these ranges.
     NOTE: If the airflow indicator ball fails to rise at or above the minimum flow level, do not use the motor/blower unit. Refer to the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Troubleshooting Guide or contact 3M Technical Service.
7. Low flow alarm check: Check the low airflow alarm by simulating a low airflow condition. With the motor/blower on:
   • Remove the airflow indicator and tightly cover the outlet of the motor/blower with the palm of your hand. The motor should automatically speed up, attempting to compensate for the low airflow condition.
   • Continue to press your palm tightly against the end of the outlet, making a tight seal. In less than approx. 30 seconds, the unit will sound an audible and vibratory alarm, and the bottom bar on the filter loading/low flow indicator will flash red. (Fig 13-5).
   • Remove your hand from the end of the breathing tube. In less than approx. 30 seconds, the audible alarm and the flashing red LED should both stop when the motor returns to the selected speed.

NOTE: If the low airflow alarm fails to sound, do not use the unit. Contact 3M Technical Service.

ENTERING AND EXITING THE CONTAMINATED AREA

Prior to entering the contaminated area, complete the Inspection procedures listed in these User Instructions and ensure the selected PAPR setup is appropriate protection for the given airborne contaminant and concentration.

1. Turn the motor/blower on.
2. It is recommended to check both the airflow with the airflow indicator and low flow alarms. NOTE: High environmental noise levels or use of hearing protection may interfere with the user's ability to hear audible alarms. Heavy clothing or tasks with high vibration levels may interfere with sensing the vibratory alarm. User may need to check for the visual alarms more frequently in high noise, or high vibration environments.
3. Don the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Assembly and Headgear. Enter the work area.
4. Leave the contaminated area immediately if any of the following conditions occur:
   1. Any part of the system becomes damaged.
   2. Airflow into the respirator decreases or stops.
   3. The low airflow or low battery alarms trigger. In the event an audible, visual, or vibratory alarm triggers, the user should immediately leave the contaminated area.
   4. Breathing becomes difficult.
   5. You feel dizzy or your vision is impaired.
   6. You taste or smell contaminants.
   7. Your face, eyes, nose or mouth become(s) irritated.
   8. You suspect that the concentration of contaminants may have reached levels at which this respirator may no longer provide adequate protection.
5. Do not turn off the motor/blower, remove the facepiece or headtop, or reach your hand into the headgear in areas where the air is contaminated. This could allow contaminants to enter the respirator and may result in sickness or death.
6. Follow your facility's specific exiting and decontamination procedures for turning off the motor/blower and removing the respirator system.

CLEANING AND STORAGE

The 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Assembly should be cleaned and inspected after each use and prior to storage. Refer to 3M Technical Data Bulletin #222 Cleaning and Maintenance of TR-600 for additional guidance.

Cleaning

While system is together and still running, conduct a general wipe down/removal of dust and debris with a soft brush or soft cloth prior to disassembly. Remainder of cleaning steps should be conducted outside of the hazardous area with the blower turned off. Inspect all parts for damage or other signs of excessive wear. Replace all damaged parts prior to storage or next use.

1. Motor/blower:
   • Clean the outer surfaces of the TR-600 assembly and battery pack (still attached) with a soft cloth dampened in a solution of water and mild, pH neutral detergent. Do not use solvents or abrasive cleaners. Do not attempt to clean the interior of the motor/blower with compressed air or vacuum. Do not attempt to clean the battery connection pins on the blower or the blower/charger connection pads on the battery – these are coated and direct cleaning with moist cloths or wipes should be avoided.
   • If additional cleaning is required, remove the filter/cartridge and breathing tube. To minimize material falling onto the motor/blower, remove the breathing tube (Fig. 12) and filter/cartridge (Fig. 6) while it is facing downward. Remove the battery. Attach the air inlet and air outlet cleaning and storage plugs (3M™ Cleaning and Storage Kit TR-653) into the TR-600 (see Fig. 16). The TR-600 can now be rinsed under running water, immersed, or put in a respirator washer for further cleaning. Water temperature should not exceed 122°F (50°C). The plug gaskets should be inspected for damage and wear prior to each use. Worn or damaged gaskets must be replaced. Washing the TR-600 while using damaged plug gaskets may cause damage to the TR-600 and void the warranty. Blowers which have been dropped or damaged should not be immersed or put into a respirator washer due to potential water ingress. NOTE: Gaskets should be replaced every 30 uses or yearly, whichever comes first, to minimize use of worn gaskets.
     
2. Battery:
   • While still on the blower, wipe the housing of the battery pack with a soft cloth dipped in mild cleaning solution. Then wipe with a soft cloth dipped in clean water. Wipe dry.
   • Remove battery and wipe down top of battery pack, if needed, with a soft dry cloth. Avoid contact with the blower/charger connection pads; if they become damp, allow to dry before reinstalling on blower or charger.
   • If needed, the battery strap included with the 3M™ Cleaning and Storage Kit TR-653 can be used to protect the pads during cleaning. With the strap in place, the battery can now be rinsed under running water, immersed, or put in a respirator washer for further cleaning.
3. Breathing tube:
   • Detach breathing tube with unit upside down (Fig. 12).
   • Clean the connection sites on the breathing tube with the water and detergent solution. The breathing tube can be immersed in water for cleaning if required. The inside of the tube must be completely dried prior to use or storage.
   • Air dry, or dry by connecting to the motor/blower unit and use it to force air through the tube until dry. Orient tube to prevent water from running into blower.
   • Optional plastic breathing tube covers (BT-922) may also be used to facilitate cleaning.
4. Belt:
   • Remove the belt from the motor/blower by lifting the bottom of the belt over the belt locking tabs and sliding the belt down. The 3M™ Easy Clean Belt TR-627 is made of a non-porous and closed-cell material and can be wiped down or submersed in a soapy water solution. The 3M™ High Durability Belt TR-626 is made of leather leads with a rubber hip belt.
   • The leather leads can be cleaned with a leather cleaner. The hip belt can be cleaned with a soapy water solution. Wipe or rinse all belts thoroughly and dry completely before next use.
5. Filter/cartridge:
   • Remove the filter cover and inspect the filter/cartridge (and prefilter/spark arrestor if used). Replace filter/cartridge if excessively dirty, wet or damaged.
   • Do not attempt to clean the inside of the filter/cartridge housing or the filter/cartridge media itself. Do not clean with compressed or pressurized air. Doing so will damage the media. The exterior of the filter/cartridge can be gently wiped down with a dry or damp cloth to remove excess dirt and debris.
   • The prefilter (3M™ Prefilter TR-6600) cannot be cleaned. Replace if excessively dirty or damaged.
   • The spark arrestor (3M™ Spark Arrestor TR-662) can be cleaned using a water and detergent solution. Completely dry the spark arrestor with a clean cloth or air dry. If the spark arrestor cannot be cleaned or is damaged, replace with a new spark arrestor.

NOTE: To minimize material falling onto the motor/blower, remove the filter/cartridge while it is facing downward (Fig. 6).

Storage

Clean the system prior to storing. Store in a clean/dry environment not exposed to contaminant dusts, gasses or vapors. Filters/cartridges may be stored attached to the blower. Do not hang blower or headtop by the breathing tube, or hang the blower from the headtop. The system must be fully inspected prior to next use. For prolonged storage, the motor must be run for 5 minutes annually to ensure proper lubrication and operation.
See "Specifications" section of these User Instructions for information on suggested storage temperatures. Humidity and ambient contaminants may diffuse into chemical cartridges once they are removed from their original packaging, which may reduce service life. Storing chemical cartridges in a clean airtight container, attached to or removed from the blower body, may help maintain remaining service life. For additional information on cartridge reuse, refer to 3M Technical Data Bulletin #142 – Reuse of Organic Vapor Chemical Cartridges.

Battery Pack Maintenance and Storage

Battery packs should be charged prior to storage. Battery pack charge depletes slowly during storage; battery packs must not be allowed to fully discharge during extended storage. For short-term storage, the battery pack may be left attached to the motor/blower. For long-term storage, the battery pack should be removed from the motor/blower. Refer to the 3M™ Versaflo™ Powered Air Purifying Respirator TR-600 Chargers and Battery Packs User Instructions for specific maintenance and storage recommendations.
3M™ Battery Packs can provide approximately 250 full charge/discharge cycle equivalents while maintaining 80% of its original capacity, when used under recommended conditions and during its first year of service. Normal use of the battery and natural aging of battery cells will gradually decrease the battery's available capacity. For additional information on battery use and optimization see the Versaflo TR-600 Chargers and Battery Packs User Instructions and 3M Technical Data Bulletin #223 3M™ Versaflo™ PAPR Battery Maintenance.
Do not store battery packs where temperatures may exceed 122°F (50°C).
