3. Unpacking and assembly
3.1 Unpacking
Check that the package is complete and that no part has
been damaged in transit or for other reasons.
A package with the complete system including
accessories contains:
1.
Blower unit including battery
1 pc
2.
Belt
1 pc
3.
Flexi hose
1 pc
4.
Air flow indicator
1 pc
5.
Battery charger
1 pc
6.
Operating manual
1 pc
The FA Flow Control is supplied with P R SL filter.
3.2 Assembly
1. Connect the battery to the blower unit.
2. Attach the unit onto the belt. Make sure that the
filter or filters are fitted properly.
3. Connect the air hose to the blower unit.
4. Connect the air hose to the headpiece and hand
tighten.
4. Usage
4.1 Inspection before every use
Do the following checks always before you start using the
equipment:
• Check that all components are in good condition
with no visible damage. Replace any damaged or
worn parts. Carefully examine the air hose, seals and
the facepiece.
• Check that there is a good connection between the
air hose and the headpiece as well as the blower unit
• Ensure that there is sufficient air flow as explained in
section "Air flow test".
• Check that the air is supplied through the whole
respiratory system from the blower to the hood.
Fully charge the battery before first use.
4.2 Air flow test
Before every use, you should conduct an air flow test on the
equipment as follows:
1. Disconnect the air hose from the blower unit.
2. Connect the air flow indicator to the unit.
3. Turn the unit on and check the air flow using the
bottom air flow level.
If the pointer on the air flow indicator goes into the red
zone, the air flow is insufficient and the filter(s) must be
replaced.
4.3 Using the FA Flow Control
1
Switch on the unit by pressing the ON/OFF button on
the control panel.
2
The airflow can be adjusted with the plus and minus
buttons (+ and –) from 170 l/min up to 240 l/min. The
number of lit green LED diodes indicates the airflow level.
The unit ensures a constant supply of air. The microprocessor
inside the unit automatically regulates the motor speed to
compensate the filter clogging and the battery state.
If the microprocessor cannot maintain the adjusted airflow,
an acoustic alarm signal can be heard and the LED diodes
display RED in colour. If possible, the microprocessor
automatically reduces the airflow to the next lower level.
3
When the airflow falls below the minimum level, the
alarm intensifies. Then the user must stop working at once
and change the filter or recharge/change the battery.
To check the alarm function, perform the air flow test as
follows:
1. Disconnect the air hose from the headpiece.
2. Cover the disconnected end of the air hose with
your hand. The blower starts to run faster after
about 20 seconds, the audible alarm activates and
the LED diodes on the control panel start blinking.
3. Remove your hand . The blower speed should
decrease.
If the blower speed does not change, it is necessary to
check the unit.
4.4 Checking the battery state
4
Press and hold the left button (–) for more than 1
second. The more red coloured LED diodes come on, the
higher the remaining battery capacity is.
4.5 Checking the filter
5
Press and hold the right button (+) for more than 1
second. The more yellow LED diodes come on, the more
clogged the filter is.
After releasing the buttons, the LED diodes return to the
green light state indicating the current airflow.
