6. Performance check, minimum flow
2019-06-04
OI06H-7018 SR 700 10
6.1 Check that the fan unit is
complete, correctly mounted,
thoroughly cleaned and
undamaged
Connect the hose from the
head top to the fan and turn it
about 1/8 of a turn clockwise.
6.2 Turn the flow meter bag
inside out so that the
transparent measuring tube is
on the outside.
Note. If the bag is turned with
the measuring tube inwards,
it can be used as a storage
bag.
.
6.3 Place the head top in the
flow meter bag and start the
fan unit.
Grip the lower part of the bag
in order to seal around the
hose.
Grip around the measuring
tube and hold the tube
vertical.
The ball should now float
level with or just over the
175 l/min marking.
If the minimum flow is not
achieved, check that:
-The flow meter is vertical
-The ball moves freely
-The bag seals well around
the hose.

7. Performance check, alarms
2019-06-04
OI06H-7018 SR 700 11
The equipment is designed to provide a warning if the air flow is
obstructed, and this should be checked in conjunction with the
flow. Check before the equipment is taken into use.
N.B. If the minimum flow is not achieved or if the alarm signals
do not operate as intended, the fan must not be used.
7.1 Cause a flow stoppage
by still holding tightly the joint
between the hose and the
flow meter bag and then
blocking off the flow meter
outlet.
7.2 The fan will now initiate
an alarm by audible and
visual signals.
7.3 If the flow meter outlet is
now unblocked and the air is
allowed to flow freely, the
alarm signals will cease
within 10 –15 seconds.
Switch off the fan and remove
the head top from the flow
meter bag.
