Each rotor arrives with a pre-set 40° arc setting preinstalled with a 1.5 nozzle plus 5 interchangeable nozzles. This flexibility allows complete customisation of flow range (180 – 750 L/h), radius (5.5 – 11 metres), sprinkler spacing (5.2 – 10.4 metres), arc adjustment (40° - 360°) and precipitation rate (6.6 – 15.24 mm/h) – Ideal when creating a completely flexible pop up system tailored to your garden’s consumption requirements. Check the performance data to allocate a nozzle for the required rate of flow and throw distance, adjust the radius using the radius screw located on the top turret and alter the arc by simply twisting the ratcheting riser from the left starting position clockwise to increase the arc or anti-clockwise to decrease.

Before installing an underground system, calculate the available water and bar pressure from your water source. Top Tip: Use the calculation below to calculate flow rate or attach a Pressure Gauge to your tap. Take the output from each nozzle in litres per minute or litres per hour and multiply by how many sprinklers you intend to run in that sprinkler zone. This tells you how many rotors can be run in a single length. Depending on sprinkler output and flow rate usually, a maximum of up to three rotors should be installed in a single zone.
