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.

Switching on and setting the flow rate

• Before switching on the V8 connect a flow meter to the air sampling head.
• Press start/pause to switch on the unit. The display will show, in this order, the serial number, the current firmware version and the battery status.
• If start/pause is pressed the display shows ‘Flow not set’.
• Press either arrow to open and start Calibration Mode and to Set Flow.

• Press start/pause to start calibration. NOTE: Run for 45 seconds to allow to stabilise.
• Press up/down arrows to adjust flow rate. (A single press advances the display by one increment, holding while pressing advances the display by 10 increments). Check the flow rate against the flow meter and adjust acording to flow requirements. (Any
• increment changes will be saved for the post test flow check, see 2.3).
• To confirm and set the flow rate press stop.
• IMPORTANT: If pump is shutdown between setting the flow and starting the test, flow will have to be re-calibrated by repeating the steps above.

2. ‘Test Completed Check Flow’, in which case continue as instructions above.

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.
