1. Setting up and using the LOWFLOW pump
Before you use the LOWFLOW pump make sure it is fully charged. A battery level indicator
shows the available power when the unit is first switched on.
1.1 Charging the battery
When the charger is plugged into the charging socket a red LED will be illuminated. The LED
will change to green when the battery is fully charged. It takes approximately 6-8 hours to
completely charge the battery.

1.2 Removing the waterproof covers
IMPORTANT: Before switching the unit on, ensure the gold air outlet and sampling head are
not covered.
IMPORTANT: BEFORE RUNNING TEST YOU WILL NEED TO SET THE
FLOW RATE
Ensure that the mechanical flow rate adjuster is OPEN (see Fig. 1).
Turn anticlockwise to OPEN and clockwise to CLOSE.

2. Setting the flowrate
2.1 - Setting the flowrate between 5-8L/min
CAUTION: REDUCE FLOW RATE BY DIGITAL DISPLAY TO 5L/MIN BEFORE USING THE
NEEDLE VALVE ADJUSTMENT (Fig.8)
The pump is set at aprox 8 L/min as a default, to fine tune this:-
2.1.1 Before switching on the LOWFLOW connect a flow meter to the air sampling head.
2.1.2 Press start/pause to switch on the unit. (Fig.2) The display will show, in this order: The
serial number, the current firmware version and the battery status.
2.1.3 Press start/pause the display shows ‘Flow not set’. (Fig.3)
2.1.4 Press either arrow to begin Calibration Mode, the pump will start running. (Fig.4)
NOTE: Run for 45 seconds to allow to stabilise. (Fig.5)

2.5 If Timed Test is selected
Press start/pause the display shows ‘Enter Run Time’
Press arrows to adjust time:-
Press start/pause to move between (Hrs) 00 (Mins) 00 (Sec) 00.
Press start/pause the pump runs and the timer starts. When the time has elapsed the

Press stop display shows ‘Test completed - Check Flow’.
Press stop display shows ‘Connect flow meter’ (now reconnect your flow meter to check
the flow rate).
Press start/pause display shows ‘Flow Check’ (any increment changes made when
setting the flow rate (see 2.1.6) will be shown.
NOTE: Wait 45 seconds for flow rate to stabilise.
Press stop display shows ‘Flow Check Complete’
Press stop to shutdown.
Note: If the pump switches itself off during either Free Running or Timed Test (i.e if the
battery dies or the sampling head gets blocked) on restart it will either show:-
1. ‘Test Incomplete, Restart Test?’, Press start/pause to resume test and see where the
previous test got to.
2. ‘Test Completed Check Flow’, in which case continue as instructions above.
3. ‘Low battery’, in which case either replace battery (within 10 minutes of disconnecting
old one) or charge pump directly from the mains for a short time to complete the flow
check.
2.4 If Free Running is selected
Press start/pause the pump runs and the timer starts counting, (you can pause during
the test by pressing start/pause)
Press stop during test and the display shows ‘Test Stop? Are you sure?’ If you are not sure,
press start/pause to continue test, if you are sure:-
Press stop display shows ‘Test completed - Check Flow’.
Press stop display shows ‘Connect flow meter’ (now reconnect your flow meter to check
the flow rate).
Press start/pause, display shows ‘Flow Check’ (any increment changes made when
setting the flow rate (see 2.1.6) will be shown).
NOTE: Wait 45 seconds for flow rate to stabilise.
Press stop display shows ‘Flow Check Complete’.
Press stop to shutdown.
2.3 Setting test mode
Press start/pause the display will show ‘Set test mode’.
Press arrows to select ‘Free Running’ or ‘Timed test’.
2.1.5 Press up/down arrows to adjust flow rate. (Fig.6)
(A single press advances the display by one increment, holding while pressing advances the display
by 10 increments).
2.1.6 Check the flow rate against the flow meter and adjust according to flow
requirements.
(Any increment changes will be saved for the post test flow check, see 2.4 & 2.5).
2.1.7 Once flow is adjusted to required flow rate, set the flow rate by pressing stop. (Fig.7)

2. Setting the flowrate (cont)
2.2 - Setting the flowrate between 2-5 L/min
2.2.1 Follow the switch on procedure as above
2.2.2Press up/down arrows to adjust flow rate down to 5 l/min
(see above)
2.2.3 Once 5 L/min has been reached, slowly turn the
mechanical flow rate
adjuster clockwise to close needle-valve and reduce flow.
(Fig.8)
CAUTION: When restarting a new job and before calibrating
flow rate, always ensure the mechanical flow rate adjuster is
open. Then follow steps to calibrate flow rate.
IMPORTANT: If the pump is shut down between setting the the
flow and starting the test, flow will have to be re-calibrated by
repeating the steps above.

3.1 Replacing the battery
The LOWFLOW pump has been specifically designed to make replacing the battery a quick
and easy task. Simply undo the two screws on the front of the battery housing, pull off the
terminal connectors, remove the battery and replace.
NOTE: This process is made easier if pump is lying on it’s back.
IMPORTANT: The terminals on the battery are colour coded red and black to match the
red and black wires of the unit. When fitting a new battery make sure that these match up
correctly.
3.2 Replacing the mast
The mast is secured on the unit in a threaded housing, so to replace just unscrew and remove.
We would also recommend removing the mast when cleaning the unit (3.3).
3.3 Cleaning the unit
The casing of the LOWFLOW pump is made from a hard wearing ABS structural foam,
making it incredibly rugged and also very easy to clean. Tested to IP65 standards
(‘Protected against low pressure water jets from any direction.’) the unit can be cleaned
under a shower hose.
NOTE: Do NOT Submerge the product fully in water.
