5. Commissioning / Winterise
5.1 Commissioning
a) Check of electrical function :
Before the water supply to the valve is opened, the coil has to be triggered through a control
unit. Through an acoustic “click” on the coil, the correct electrical function can be
determined. (The click arise through attracting the relay armature.)
b) Make sure that the manual operation stands on AUTO or OFF (Turn screw totally in or
out). In both positions it is warrant that the valve closes after the water supply.
c) Open water supply to the sprinkler slowly. Probably the valve opens for a short time, but
after 30 sec. it should close on its own.

d) After opening the water supply and after the max. working / operation pressure is reached,
every seal has to be checked / examined.
e) Check valves and sprinkler for perfect function, when opening the valve manual.
That can be executed by turning the manual operation to the right, until the sprinkler head
pops up. So that the water jet do not hit the operator, the manual operation should be
opened carefully. You can see the spray direction of the sprinkler on the out gushing water
and so the operator can see where he has to stay for not getting wet.
f) The desired pressure on the sprinkler nozzle, can be adjusted on the pressure regulation
screw while the sprinkler is working.
If on the sprinkler nozzle the min. pressure is adjusted, there is appr. 3 bar pressure on
the nozzle.
