Product Usage Instructions
Setting up and using the V8 pump
Before you use the Variflow 8 pump make sure it is fully charged. A battery level indicator shows the available power when the unit is first switched on.
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.
Removing the waterproof covers
IMPORTANT: Before switching the unit on, ensure the gold air outlet and
sampling head are not covered.

Maintenance
Replacing the battery
The V8 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 it.
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.
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).
Cleaning the unit
The casing of the V8 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.
