  • For H&S reasons we do not recommend working a full day with a backpack on your back. Rest frequently and schedule changes in work routine during the day.

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

To read the voltmeter: Turn the pump switch to the lower ON (II) setting – when GREEN light shows, this indicates the backpack is fully charged; when just the yellow or red lights show, this indicates the backpack needs to be re-charged soon; when the red light only shows it indicates the backpack must be recharged immediately. 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.

Please Note:

  • 240v power leads (such as kettle and computer leads) are not compatible with this backpack for charging and will destroy the unit if used
  • Only a blade fuse between 3 and 10 amps must be used with this backpack. Using a different amp blade fuse will invalidate the warranty on the backpack
  • The backpack is warrantied for use with water only – due to health and safety reasons no warranty returns will be accepted if the backpack has been used with any chemicals
    Any unauthorized modification to this unit will invalidate the warranty on the backpack
