To use the variable flow controller on the V3 Backpack, push the on/off switch to the upper “ON” (I) position and then turn on the unit using the flow control silver dial until the desired flow rate is reached. When desired flow rate is set, you can then switch on and off to this speed using just the on/off switch. For full flow rate push the switch to the lower “ON” (II) setting.


The battery comes charged as standard. However, it is recommended that you charge the battery again until the green LED on the charger illuminates. The battery charger will show a red LED whilst charging and when battery is less than full.


To read the backpack voltmeter: Turn the pump switch to the lower “ON” (II) setting -  when the green light shows, this indicates the backpack is fully charged; when just the yellow light (or red light) shows it indicates the backpack needs re-charging. Failure to do so and continuing to use the backpack in this battery state could damage the battery and shorten its lifespan. 


  • For prolonged battery life and to avoid battery cell damage it is best to keep the battery charged as often as possible, preferably after each use.
  • Only charge the unit using the supplied battery charger. Do not use a computer lead or similar.
  • If using with chemicals, always ensure that the unit is rinsed out fully and the pump and hose is flushed through for a few minutes with pure water before storage



What if your new Backpack runs, but does not pump water? This is usually becuase of an Air-Lock - this can be sorted by following these steps:

1. Fill up the backpack to at least half way; this helps to force the water through.
2. Unscrew the Claber Aquastop connector, or remove any fitting completely. If it is not possible to remove the end fitting, then plug a male tail into the female outlet to allow water and air to flow easily out - do not plug a pole hose length into it.
3. It also helps if the orange hose is laid flat on the floor, ideally below the level of the pump.
4. Run the backpack for at least 10-15 seconds and water should start to come through.
5. If the above does not work then with the backpack switched on, it may be worth trying to suck water through an open flow hose or fitting to start the pump pumping - only do this if using pure water!
