Turn the flow meter bag inside out and the flow
meter appears.
Tip: When flow meter bag is turned inside out
with the flow meter turned in the bag can be
used as a storage bag.
Place the head-top in the flow meter and start
the fan unit.
Grip the lower part of the bag to seal around the
breathing hose.
Grip the flow meter tube with the other hand so
that the tube points vertically upwards from the
bag.
Read the position of the ball in the tube. This
should hover at a level with or slightly above the
upper marking on the tube.
If minimum flow is not achieved, check that:
•
The flow meter is held upright.
•
The ball moves freely.
•
The bag seals well around the hose.
The equipment is designed to provide a warning
if the air flow is obstructed. This alarm function
should be checked in conjunction with the flow
check before the equipment is used.
Cause an air flow stoppage by gripping the top
part of the bag or by shutting off the flow meter
outlet.
The fan unit should then initiate alarms by sound
and light signals.
