6.2
a) Check electrical function:
Before any water supply to the sprinkler is opened, activate the coil by means of the controller. If you
hear a 'clicking' sound from the coil, the electrics are working properly. (The click is produced by the
movement of the armature.)
b) Ensure that <Manual opening> is set to AUTO (turn screw for <Manual opening> as far as it will go to
the left). This setting ensures that after water is supplied the sprinkler closes if it has no power.
c) Slowly open supply of water to the valve until operating pressure is built up. It is possible that the sprin-
kler will briefly open, but should then automatically close after at most 30 seconds.
d) Once the water supply has been opened and max. operating pressure has been reached, check sprinkler
and connection for leaks.
e) Check that sprinkler is working properly: Open sprinkler using <Manual opening> by moving the
screw for <Manual opening> into the position between AUTO and OFF (approx. 1 rotation). Sprinkler
head rises and starts to rotate.
!
Do not stand in front of the nozzle opening!
f ) Close <Manual opening> and put into AUTO position (see point 6.2b).
Sprinkler must stop water flow within 30 seconds.
g) Keep repeating steps 'e' and 'g' until the sprinkler is working faultlessly.
h) Check once again that it works correctly when activated electrically from the controller.
