Between 5-10 l/min
Press up/down arrows to adjust ow rate. (A single press advances the display by one
increment, holding while pressing advances the display by 10 increments).
Check the ow rate against the ow meter and adjust according to ow requirements.
(Any increment changes will be saved for the post test ow check, see 1.6/1.7).
Once ow is reduced to required ow rate, set the ow rate by pressing stop.

2.1 Replacing the battery
The V8 LOWFLOW pump has been specically designed to make replacing the
battery a quick and easy task. Simply undo the two screws on the front of the
battery housing, pull o 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 tting a new battery make sure that these
match up correctly.
2.2 Replacing the mast
The mast is secured on the unit in a threaded housing, so to replace just unscrew
and remove.
IMPORTANT: Please do not lift the pump by the mast.
2.3 Cleaning the unit
The casing of the V8 LOWFLOW pump is made from a hard wearing ABS structural
foam, making it incredibly rugged and also very easy to clean. Tested to IP65
