Installation
Set-up the unit
Place the unit in the pond on a horizontal, firm and sludge free ground and ensure that it is completely covered by
water.
Setting the fountain/water feature (Fig. B, C)
Pull the nozzle tube (11) to the desired length. Undo the clamping screw (10), vertically align the nozzle tube (11) and
fasten the clamping screw (10) hand tight.
Fully open the rotary regulator (18) for the fountain. The rotary regulator (17) for the features or the water course is
also used to control the fountain/water feature. The additional water recirculation via the lateral outlet improves the
filtering effect, even if the feature or the water course is not connected.
