3.2 Functional check
• Check that the mask is complete, correctly assembled,
thoroughly 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.
• Check the condition of the head harness. The head harness
is a consumable item and should be replaced if there are any
signs of wear or reduced elasticity.
• On every occasion before using the equipment:
Check on the rated capacity of the compressed air
o
system.
Check the maximum number of users permitted.
o
Check the number of users already connected.
o
Check that the minimum flow of air through the facepiece is at
least 150 l/min.
Proceed as follows:
Connect the breathing hose to the control valve. Fig. 3.
o
Connect the compressed air supply tube to the control
o
valve. Fig. 4.
Turn the control valve knob anti-clockwise as far as it will
o
go, in order to throttle the airflow rate to a minimum. Fig. 3.
Place the facepiece in the bag and grip the opening of the
o
bag so that it seals around the breathing hose.
Grip the flow meter with the other hand and hold it so that
o
it points vertically up from the bag. Fig. 2.
Read the position of the ball in the tube. It should float level
o
with or just above the marking on the tube.

If the flow rate is below the minimum value, check that
-
• the flow meter is vertical,
R03-1530
• the ball can move freely,
R03-1531
• the air supply is not restricted by kinks or other restrictions

• Arrange the control valve in a way that allows easy adjustment
of the flow rate and a strict watch over the breathing hose, i e.
it must not be placed on the back of the waist.

If any leakage is detected, check the inahalation and
-
exhalation valves, adjust the straps of head harness or
-
switch to alternative size of the respirator. Repeat the fit

valve outlet. Fig. 3.
H03-2810
• Unroll the compressed air supply tube and make sure that it
is not twisted.
• Connect the compressed air supply tube to the control valve
inlet. Fig 4.
Mask – Fitting
• Put on the mask and adjust the head harness strap until the
mask fits well and comfortably. Fig. 5.
• The retainment clip on the breathing hose is ideal for
fastening the hose close to the body. Fig. 1:1a.
Airflow rate
• Use the control valve knob to set the air flow rate to suit your
current work intensity. Fig. 3. In the fully closed position (turn
the knob anti-clockwise), the flow is about 150 l/min. In the
fully open position (turn the knob clockwise), the flow is
about 320 l/min.
