conditions may result in deterioration over a shorter period. For indoor or occasional use we would anticipate a
service life of approximately 5 years, provided the headtop is stored as stated below.
DOFFING
Do not remove the headtop or turn off the air supply until you have vacated the contaminated area.
1. Grasp the face seal, raise the visor, and lift the headtop off the head.
2. Switch off the air filter unit or disconnect the compressed air supply tube from the regulator.
3. Unbuckle 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.
CLEANING INSTRUCTIONS
Use a clean cloth dampened with a mild solution of water and liquid household soap.
Do not use petrol, chlorinated degreasing fluids (such as trichloroethylene), organic solvents or abrasive cleaning
agents to clean any part of the equipment.
To disinfect use wipes as detailed in Reference leaflet (3M 105).
MAINTENANCE
Maintenance, servicing and repair must only be carried out by properly trained personnel.
Use of unapproved parts or unauthorised modification could result in danger to life or health and can invalidate any
