RPB PX4 AIR (01) PDF Document

The RPB PX4 AIR PAPR is NOT FOR USE if:

• In atmospheres immediately dangerous to life or health (IDLH).

• Wearer cannot escape without the aid of the respirator.

• Atmosphere contains less than 19.5% oxygen.

• In abrasive blasting applications.

• For protection against hazardous gases (e.g., carbon monoxide).

• Contaminants are in excess of regulations or recommendations.

• Contaminants or contaminant concentrations are unknown.

• Work area is poorly ventilated.

• The temperature is outside the range of 14°F to 131°F (-10°C to +55°C). If the internal battery temperature reaches 140°F (60°C) the unit will completely shut down.

• Flammable or explosive atmosphere is present. This system contains electrical parts that are not suitable for use in such environments. The RPB PX4 AIR is not intrinsically safe.

For a Powered Air source, check that the contaminated area is within the limits of use for a Powered Air Purifying Respirator and determine the type of contamination. Once the contamination level has been confirmed, you can then determine the filter cartridge to be used for the application to ensure you are sufficiently protected. Make sure that the area is well ventilated and that regular air samples are taken to confirm the atmosphere stays within the levels recommended by OSHA and other governing bodies.

BEFORE INITIAL USE – BE TRAINED AND MEDICALLY QUALIFIED

Do not use this device until you have read this manual and the approved head top Instruction Manual and been trained in the respirator’s use, maintenance, and limitations by a qualified individual. Do not wear this respirator until you have passed a medical evaluation by a qualified physician or other licensed health care professional (PLHCP).

MAKE SURE THE SYSTEM IS READY FOR USE

Make sure you have a complete system. The RPB PX4 AIR is only one component of a NIOSH approved respirator system. Verify that you have all required components:

• Respirator Head-top Assembly

• Breathing Tube Assembly

• RPB PX4 AIR PAPR

Inspect all components daily for signs of damage or wear and tear that may reduce the level of protection. Remove any damaged component or product from service until repaired or replaced with genuine RPB brand replacement parts. Replace the HE filter when it is visually dirty, the filter media is damaged, or the airflow is reduced. Inspect the prefilter and the spark arrestor for damage or blockage. Keep the inside of the respirator clean at all times.

Make sure that the PAPR is correctly assembled in the configuration that suits your application. Never use the respirator without a HE filter in place depending on the application. It is recommended that a prefilter always be used. For applications that produce sparks or high heat, use the FR (Fire Retardant) specific model of the RPB PX4 AIR with the FR belt and spark arrester.

You should leave the work area immediately if:

• Any product component becomes damaged.

• Vision is impaired.

• Airflow stops or slows down, or alarm sounds. Do not use Powered Air Purifying Respirators if airflow is less than 6 cfm (170 lpm).

• Breathing becomes difficult.

• You become dizzy, nauseous, too hot, too cold, or ill.

• Your eyes, nose, or skin become irritated.

• You taste, smell, or see contaminants inside the helmet.

• You have any other reason to suspect that the respirator is not providing adequate protection.

Welding and Grinding

For welding, grinding, and other applications that produce sparks or high heat, be sure to use the FR (Fire Retardant) specific model of the RPB PX4 AIR with the FR belt and spark arrestor in place.

Confined Spaces

If this respirator is used in confined spaces, ensure the area is well ventilated and that all contaminant concentrations are below those recommended for this respirator. Follow all procedures for confined space entry, operation, and exit as defined in applicable regulations and standards.

Welding in Confined Spaces

Welding in a confined space can present an atmospheric hazard due to the generation of contaminants and displacement of oxygen. A pressure-demand SCBA or a multifunctional pressure-demand supplied-air respirator with self-contained air supply shall be used during welding in confined spaces when welding can reduce the ambient oxygen level and supplemental ventilation and atmospheric monitoring are not provided according to 29 CFR 1910.146 and ANSI/ASSE Z117.1.

To reduce the risk of battery fire, explosion, or electric shock with the charger, follow these precautions and procedures:

Before charging:

• Allow the battery to cool before charging if it feels hot.

• Inspect the battery pack before each time it is charged. If there are any cracks or damage, do not charge the battery pack.

• Inspect the charger and power cords before use. Replace if any parts are damaged. Do not substitute, modify or add parts to the chargers. Do not attempt to service the chargers. There are no user-serviceable parts inside.

• Use only the provided charger and cord.

Where to charge:

Charge only:

• indoors,

• in a dry area,

• away from sources of heat,

• away from anything that can burn if exposed to heat or flame,

• in a well-ventilated place,

• where the charger can be monitored and easily observed during charging.

Battery care:

• Do not use the battery outside the recommended temperature limits 14°F to 131°F (-10°C to 55°C).

• Do not charge the battery outside the recommended temperature limits 32°F to 113°F (0°C to 45°C).

• Do not store the battery outside the recommended temperature limits 14°F to 113°F (-10°C to 45°C).

• Do not disassemble. Do not immerse in water or other liquids.

• If the battery contacts are accidentally shorted by metal, built-in protections will make the battery appear uncharged. To reset it, place the battery on the charging station.

Disposal:

Dispose of battery packs according to local regulations. Do not crush, disassemble, dispose of in standard waste bins, in a fire, or send for incineration.

1. Fit the battery to the charging station by connecting the left side and rotating the battery down to latch it into place.

2. Connect the Power Pack to the charging station. Connect the Power Pack to the Mains Electrical Source (110 – 240v), and charging will begin.

3. Follow the indicators from left to right on the front of the charging station to know the status of the charge process. The triangle warning light will indicate a problem charging. When all three lights display green, the battery is fully charged.

4. To remove the battery from the charging station, press the release latch on the bottom of the battery and lift the battery from the station.

The battery has a power capacity indicator showing the level of charge from 20% to 100%. Press the test button to reveal the result.

To attach the battery to the RPB PX4 AIR, connect the left-hand edge to the base of the unit and rotate it up into position, making sure that the latch snaps into place.

The HE filter should be replaced if the airflow alarm is activated, or the flow indicator reading falls below the 6cfm (170 slpm) minimum airflow. The HE filter should also be replaced if there is damage to the filter media, such as a tear or puncture, or if the filter media becomes wet.

The Prefilter is recommended to be replaced when it is dirty or damaged, or at the same time as the HE Filter.

The Spark Arrestor should be replaced if it becomes damaged or clogged with debris.

1. A 03-981 Prefilter is mounted in front of the 03-985 HE filter to prolong its life.

2. In environments with sparks, such as welding or grinding, use the 03-982 Spark Arrestor in front of the 03-981 Prefilter to reduce the risk of fire.

3. Mount the 03-985 HE Filter into the Door. Note that the logo on the front of the Filter should be at the bottom.

4. Slide the Door onto the hinge block on the right side of the fan unit (as you face it), rotate the door to the left, and latch it in place.

WARNING: Depending on the contaminants filtered by the RPB PX4 AIR, the used filter itself may be hazardous. Take appropriate precautions when handling to avoid exposure to released contaminants; a company disposal procedure may be needed.

1. Make sure the 03-911 fan unit is switched off before attempting to open the Door. (Note: Press and hold the button to power off.) If the unit is on, contaminants may be pulled into the unit, and suction may make it difficult to remove the filter.

2. Depress the latch, then rotate the door to the right and lift the door off the latch.

3. Remove the 03-985 filter from the Door and dispose of it in a suitable way.

4. Install the new replacement 03-985 filter as instructed. Inspect the 03-981 Prefilter and replace as needed.

1. Select the flexible breathing tube that suits your respirator head-top (check that the fitting connects to your respirator type).

2. Take the end that fits to the respirator and connect it securely.

3. Now take the bayonet end, insert the connection into the RPB PX4 AIR and make sure the 2 small pegs line up with the slots in the RPB PX4 AIR outlet.

4. Twist the breathing tube clockwise a ¼ turn to lock into position. Make sure that it is fully locked in position.

The power button is on the right side of the unit as you look at the front of the RPB PX4 AIR.

POWER ON: Press and hold the power button for about 1 second. The unit will always start in the low speed setting and should reach nominal flow within 5-10 seconds. Allow the unit to warm up for 5 minutes or until the flow meter is in the safe range before use.

BATTERY INDICATION: The top row of green lights indicate the charge of the battery.

• 3 lights: Fully charged.

• 1 light: Battery is getting low.

• Top row of lights flashes red and alarm sounds: The battery is out of charge. Immediately return to a safe environment and remove the respirator to change/charge the battery.

POWER OFF: Press and hold the power button for about 1 second and the unit will turn off.

Speed Settings: Cycle through the 3 speed settings by pressing the Power Button. Each button press will advance through these speed settings:

• Speed 1 – 170 slpm

• Speed 2 – 210 slpm

• Speed 3 – 240 slpm

Operation Legend: The blue lights indicate the selected fan speed. The red lights indicate the level of blockage.

• Lights flash red and blue: The selected fan speed cannot be reached, but sufficient air supply (170 slpm) can still be reached.

• 3 lights flash red and the alarm sounds: Insufficient air supply is being produced. Return to a safe environment and check the filter and/or the airway for blockage. If the filter is contaminated, replace it with a new cartridge.

When the alarm sounds, it is recommended that you leave the work area immediately. Do not remove the respirator, remove the filter, or disconnect the breathing tube while in the work area. Once outside of the work area, power the unit down and resolve the problem.

Alarm volume is 85 dBA at 4″ (104mm).

1. Choose the appropriate belt for the working environment: Standard (07-765) or FR (07-765-FR for welding, grinding, high heat applications).

2. Thread the belt through the support in a left to right direction when looking at the front of the RPB PX4 AIR.

3. Take the loose end of the Belt and thread from behind through the outer slot (slot furthest out from the RPB PX4 AIR) in the left support and then back through the inner slot (closest to the RPB PX4 AIR).

4. Thread the belt through the belt loops so that it passes between the loop and the support.

5. Thread the belt through the inner slot from the back and then back through the outer slot.

6. Now thread the clip end of the buckle on to the belt and pull to the desired length.

Before each use, the unit should be inspected for the following points:

1. RPB PX4 AIR PAPR SYSTEM: Make a visual inspection of the entire unit, which includes the motor housing, filter door and door cover, filter and pre-filters, battery, belt and breathing tube. Also inspect that the correct hood or face piece is attached.

2. BATTERY PACK: Check that the battery has a full charge to confirm sufficient charge for the work period. Make sure the battery is securely fitted to the RPB PX4 AIR PAPR.

3. BREATHING TUBE: Inspect the breathing tube completely, looking for splits and cracks. Ensure the fittings are held securely in the tube and that the O-ring is in place on the bayonet fitting. Make sure the breathing tube fits firmly into the RPB PX4 AIR unit and seals without any leaks.

4. HE FILTER: Inspect the filter casing for cracks and distortions that will affect the seal. Inspect the filter paper and the seal carefully for dirt, cuts, tears, distortions, or indentations. The seal can be wiped clean with a damp cloth. Do not use solvents or detergents. The HE filter paper must not be cleaned or submersed in water. All damaged filters, pre-filters and spark arresters must be replaced before use.

5. AIRFLOW METER: Check the ball in the 04-091 airflow meter is moving freely. Insert the flow meter into the outlet of the RPB PX4 AIR and rotate ¼ turn to lock it in place vertically. Turn on the RPB PX4 AIR and let the air stabilize over a 30 second period. Check that the ball is sitting above the minimum flow rate marker. Do not use the unit if it does not reach the minimum airflow rate.

6. ALARM SIMULATION: Check the operation of the airflow alarm. Power on the RPB PX4 AIR and place the palm of your hand over the outlet. Hold your hand tightly over the outlet until the alarm sounds (audible alarm and Red LED indicators) after 5-10 seconds. Remove your hand; the alarm and LED should return to normal operation.

7. CLEANING: The RPB PX4 AIR unit can be cleaned with a damp cloth and mild detergent on the external surfaces and the face of the fan motor housing. WARNING: DO NOT submerge in water or use solvents on any parts of the RPB PX4 AIR.

8. BELT LOOPS/SUPPORTS: Check the Belt Supports and Belt Loops for cracks or excessive wear. If present, they should be replaced.

The RPB PX4 AIR should not be stored with the filter or battery attached if not being used for long periods of time. Store it in a clean, dry environment, away from direct heat sources between 14°F and 114°F (-10°C and +45°C), at a relative humidity of less than 70%.

All batteries must be stored in a cool dry atmosphere. DO NOT store a battery in ambient temperatures that exceed 114°F (45°C). It is recommended that the battery is stored at 14°F to 114°F (-10°C to 45°C) as the optimal temperature range for storage, to maximise the life of the battery.

All filters must be stored in an airtight plastic bag or container so that they are not exposed to contamination. Partially used filters should also be stored in an airtight plastic bag so that contaminants are contained.
