(For valve-in-head sprinklers)
c) Check electrical function:
Before opening water supply to the sprinkler, activate coil via the control module.
The sound of a 'click' on the coil lets you determine if the sprinkler's electrical
function is working correctly (the click is caused by the rotor being activated).
d) Make sure that 'Manual opening' is set to AUTO (turn screw for 'Manual opening'
round to the left as far as it will go).
On this setting, whenever it is not switched on the sprinkler is guaranteed to close
following the supply of water.
i) Slowly open water supply to the valve until operating pressure is present. The
sprinkler may briefly open but should then close automatically after no more than 30
seconds.
j) Once the water supply is open and the maximum operating pressure has been reached,
check sprinkler and connection for leaks.
k) Check sprinkler is working flawlessly:
Open sprinkler using 'Manual opening' by turning the screw for 'Manual opening' to
the position between AUTO and OFF (approx. 1 revolution). Sprinkler head rises and
begins to rotate.
Do not stand facing the nozzle opening!
Set desired output pressure by turning the 'Pressure regulator screw' to the right (-)
as far as it will go (minimum pressure). The output pressure is now set to
approximately 3 bar. If you turn the 'Pressure regulator screw' one complete
revolution to the left (+), the output pressure will go up by 1 bar.
l) Close 'Manual opening' and put in the AUTO position (see point 5b).
Sprinkler should stop the throughflow of water within 30 seconds.
m) Perform steps e) and f) again repeatedly until this functions are flawlessly.
n) Check again that the sprinkler is working correctly by starting it electrically from the
control module.
