7. Watering volumes:

The amount of irrigation differs depending on how many water sprayers are in the system. In ad-

dition, the set interval time on the control unit plays a major role.
The amount of water per watering session can be found in the table below. The watering takes 

place automatically at sunrise and sunset.
Please note, however, that these are approximate watering volumes. The volume of water can 

vary slightly.
In order to use the watering  pump to full capacity, at least 10 sprayers should be connected. 

Since the max. delivery rate of the pump is approx. 100 l/h, the total watering quantities do not ch-

ange significantly. The water quantity is only distributed in smaller quantities via several sprinklers.

8. Care and maintenance

The maintenance of the ‘WaterSpray Professional’ is straightforward. If the sprayer nozzles are 

clogged, proceed as follows to clean them: 

Note: Please switch off the watering computer before cleaning!

1.  To be able to clean the sprayer, pull it off the water hose. 

2.  Then carefully unscrew the sprayer’s cap, making sure that the inside of the sprayer does not 

fall out. 

3.  Rinse the sprayer with clean water and clean the hole with a toothpick. 

4.  Then screw the sprayer back together.

9. Faults

-   During operation, water runs out of the check valve.

  The non-return valve has been attached the wrong way round. Turn it around and attach it the 

other way around.

-   No water comes out of some sprayers.

  Clean the sprayer as described under point 8!
-   Water is continuously leaking from a sprinkler. 

  Check the continuity and correct seating of the check valve. The check valve may bave been 

attached the wrong way round.
