3. Setup
3.1 Battery Installation
Before first use, ensure the 18V 2.5 Ah battery is fully charged using the AL 1810 HP charger. Once charged, insert the battery into the battery control unit.

This image shows a hand sliding the charged 18V battery into the designated slot on the top of the green and black battery control unit. The control unit is designed to securely hold the battery during operation.
3.2 Mounting the Control Unit
The battery control unit offers flexible mounting options:
- Tank Mounting: Use the provided tank mounting system to hang the control unit directly on the edge of your rainwater tank.
- Wall Mounting: For a more permanent setup, attach the control unit to a wall using the wall mounting system. This option also provides a theft-proof installation when secured with a screw.

3.3 Pump Placement and Hose Connection
Submerge the rain water pump into your rainwater tank. Connect the 2.5m connection hose to the pump and then to your desired watering accessory (e.g., spray gun, sprinkler).
