cleaned and undamaged.
Check particularly carefully
the inhalation and exhalation
membranes and their seats.
The membranes are
consumables and must be
replaced if there are any
signs of damage or ageing.
1.2 The membranes are
consumables and must be
replaced if there are any
signs of damage or ageing.
Check the condition of the
head harness. The head

measured through the mask -
is at least 5.3 CFM (150 l/min)
Connect the breathing hose of
the mask to the control valve.
1.5 Connect the compressed
air supply tube to the control
valve.
1.6 Turn the control valve
knob anti-clockwise as far as

other hand and hold it so that
it points vertically up from the
bag.

ball in the tube. It should float
level with or just above the
marking on the tube 5.3 CFM
(150 l/min).
If the flow rate is below the minimum value, check that
• The flow meter is vertical.
• The float can move freely.
• The air supply is not restricted by kinks or other restrictions in the
hoses.

on top of the cartridge. Grasp
both protective elements.
Squeeze hard until you hear
the particle filter snap onto
the gas filter.

sideboards or if your face is unshaven or deeply wrinkled, if you wear
glasses, or if the exhalation valves are defective or dirty.
