Oase Filtral 2500 UVC Instrucciones De Uso página 15

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 wa-
ter.
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 fil-
tering effect, even if the feature or the water course is not connected.
