Cleaning And Disinfection; Fault Finding; Storage And Transportation - 3M Powerflow 7900PF Guide Rapide

Airflow Check
Insert airflow indicator into the Powered Air Turbo outlet, ensuring filter and a
fully charged battery are fitted. Switch on battery.
Check airflow (see Figure 3) switch off battery and remove airflow indicator. If
mimimum airflow is not achieved see fault finding.
OPERATING INSTRUCTIONS
DONNING
With the battery pack switched OFF:
1. Clip battery pack onto waist belt.
2. Fully loosen all 6 head straps, then place harness on the back of the head
and pull the facepiece down over the face (Figure 4).
3. Progressively tighten the harness starting with the lower straps then upper
straps (Figure 5). Do not overtighten.
4. Perform a Negative Pressure Fit Check. See Figure 6.
5. Remove hand from filter inlet and switch ON battery pack.
FIT CHECK
Place the palm of the hand over the inlet, inhale gently and hold your breath for
five to ten seconds.
If the facepiece collapses slightly a proper fit has been achieved.
If an air leak is detected, reposition the respirator on the face and / or re-adjust
the tension of the elastic strap to eliminate the leakage.
Repeat the above fit check.
If you CANNOT achieve a proper fit DO NOT enter the hazardous area.
See your supervisor.
Users should be fit tested in accordance with national requirements.
For information regarding fit testing procedures, please contact 3M.
IN USE
Use in the power off state is not normal. However, reduced protection is
provided to allow safe exit from the contaminated area.
Take care to prevent the battery cable from becoming looped around protruding
objects. If this should occur vacate the contaminated area and check apparatus
is undamaged.
The 'in-use' life of the product will vary with frequency and conditions of use.
In everyday use, it is recommended that the product is discarded after
approximately 5 years service, provided the product is stored and maintained
as stated below.
Some extreme conditions may result in deterioration over a shorter period.
DOFFING
Do not remove the facepiece, filters or, when in Supplied Air mode, turn off the
air supply until you have vacated the contaminated area.
1. Release the tension on the head straps.
2. Carefully lift facepiece off the face and remove the respirator by lifting up and
away from the face.
3. Switch off the Powered Air Turbo.
4. Unclip the battery from the waistbelt.
NOTE: If the respirator has been used in an area that has caused it to
become contaminated with a substance requiring special
decontamination procedures it should be placed in a suitable container
and sealed until it can be decontaminated or discarded.

CLEANING AND DISINFECTION

Cleaning is recommended after each use. Use a clean cloth dampened with a
mild solution of water and liquid household soap. If personal shower
decontamination is necessary, do not allow water to enter the filter. Use the
decontamination kit (See reference leaflet). Do not allow water to enter the inlet
or outlet of the Powered Air Turbo or to come in contact with electrical
connections. Following cleaning or decontamination procedures, ensure that
electrical connections are free from dust/water and dry as necessary. The 3M™
105 Wipe should be used to wipe the face seal of the product. Disinfect
respirator by soaking in a solution of quaternary ammonia disinfectant or
sodium hypochlorite or other disinfectant. Rinse in clean, warm water and air
dry at room temperature in a non-contaminated atmosphere.
NOTICE
Do not use cleaners containing lanolin or other oils on these products.
Do not use petrol, chlorinated degreasing fluids (such as trichloroethylene),
organic solvents or abrasive cleaning agents to clean any part of the
equipment.
Do not autoclave.

Replace Battery pack
The facepiece should be repaired or disposed of if damaged or defective parts
are observed. See Preparation for Use.
A maintenance record should be kept at the monthly checking stage to comply
with Health and Safety Regulations. This record should be kept for at least 10
years.
If disposal of parts is required this should be undertaken in accordance with local
health and safety and environmental regulations.
^ DO NOT DISPOSE OF LITHIUM BATTERIES IN A FIRE OR SEND FOR
INCINERATION. Battery packs should be treated as special waste and in
accordance with your local environmental regulations.
Head Harness Removal
To remove the head harness, push the buckles forward whilst holding the
facepiece in the other hand to release the buckle from the harness button. To
replace the harness, push the buckle over the harness button and slide under the
button to lock into place. See figure 7.
Visor Replacement
Remove the screws from either side of the visor frame and remove the two
halves of the visor frame. Roll back the facepiece from the edge of the visor and
remove. To replace the visor, align the centre of the lens with the centre line of the
facepiece. The centre of the visor is marked by 2 small dots, one at the top centre
and one at the bottom centre. Place the visor into the facepiece ensuring that it is
sealed on all sides and reattach the visor frame. Replace the screws and tighten.
See figure 8.
Nose Cup Inhalation Valve Replacement
To remove the nose cup inhalation valve, grasp the valve and pull the valve stem
out from the valve seat. To replace push the valve stem into the hole in the valve
seat until locked in place. The valve stem should point away from the face when
worn.
Main Inhalation Valve Replacement
The inhalation valve is designed to seal the interface between the inhalation port
on the facepiece and the filters. Remove valve from the inhalation port. To
change the valve diaphragm, push the diaphagm over the centre post of the
inhalation valve. Insert the inhalation valve into the inhalation port ensuring seal is
secured in place.
Exhalation Valve Replacement
Remove the exhalation valve cover by pressing the 2 prongs on either side of the
centre opening and sliding the cover downwards. Remove the exhalation valve
by pulling on the edge of the valve. To replace, push the new valve down onto the
centre post of the valve seat. Replace the exhalation cover. See Figure 9.
