5. Commissioning / Winterise
5.1.1 Connection
Measurements:
5.1.2 Measurements
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) 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.
c) After opening the water supply and after the max. working / operation pressure is reached,
every seal has to be checked / examined.
d) Check valves and sprinkler for perfect function, when opening the valve manual.
e) While operation of the sprinkler, there is the possibility to adjust the desired irrigation
sector on the spring stop [14].
f) After the complete ventilation of the sprinkler the current supply to the coil must be
stopped, than the sprinkler has to close.
5.2 Winterise
Before beginning of the frost period the sprinkler has to be totally drained off.
Therefore there must be connected a powerful compressor on the network / main circuit.
Open the valve on the sprinkler until only air is coming out of the nozzle.
 Sprinkler is equipped with a automatic drainage valve and could be winterised by gravity,
just by drainage the pipe.
 After the drainage the solenoid has to be activated at least 5 times, so that remaining water
can be pressed out of the solenoid housing.

7.3.1 How to check sprinklers, which do not open
Check solenoid in or at the controller for efficient operation.
Engage valve and check at the relief exit of the controller for a brief water splash
to come out
Exchange solenoid at the controller only when there is no pressure in the line
7.3.2 How to check sprinklers, which doesn’t close
Control line has not been ventilated completely.
Foreign particles are blocking the valve
There is a leak in the hydraulic system.
The retaining circlip [9] on top of the valve is not fitted correctly and the valve has
been pushed out of it's seat by the operating pressure.
Check the outlet of the solenoid valve for correct functioning. To implement this,
disconnect the control line. The valve at the controller is normally open (without
current).

2. Installation
Dimension
When installation to the public water supply system, you must pay attention to the
regulations of the water utility respectively guideline of the DVGW (Deutscher
Verein der Gas- und Wasserfachmänner e.V.).
On stony ground, pipes are to be laid in a sand bed. The sand bed should surround the
pipe everywhere 10 cm.
It is necessary that the installation of the pop-up sprinkler is in the same level as the
ground.
Under each sprinkler there must be, a gravel packing of 3 – 10 buckets of gravel,
grading approximately 32. A perfect drainage of the sprinkler housing is very
important.
Pop-up sprinkler
Main pipe
Coarse gravel
Swing joint
PE-connection
T-piece
Flush the pipes proper before installation of the sprinklers
3. Commissioning
Pipes must always be filled slowly, that means you must open the gate valve gradual, under
observance of the assigned operating pressure. Despite of a thoroughly flushing it may happen
that the sprinkler nozzle is blocked. To clean the nozzle you must turn off the nozzle and flush
the sprinkler. To unscrew the nozzle you must put a block under the lid or take off the cover.
(Use socket spanner)

4. Adjustments
4.1 Sectors
The sectors of the reference part circle of sprinklers are adjusted by pushing the spring stop
at the end, which expand the spring. You achieve a crude adjustment before installation,
the fine adjustment should be done on the working sprinkler.
4.2 Casting range
The casting range is regulated through the application of different nozzles and pressures.
(Further information see catalogue)
4.3 Jet deflector screw (type SIS120P no adjustment available)
 The jet deflector screw is for adjustment of the near irrigation around the sprinkler. If you
screw in further the screw in the water jet, the „rainfall“ consistency around the sprinkler
increases, the casting range decreases. If you unscrew the interruption screw the irrigation
around the sprinkler decreases and the casting range increases.
5. Maintenance / Cleaning / Repair
To clean or suction the housing you must lift the sprinkler by hand or remove the cover
from time to time.
Examine function of gravel package
In case that the sprinkler insert or nozzle head is dirty, only clean it with water.
Do not use lubricants or grease, other wise the gliding plate in the sprinkler might be
damaged!!!
Please dismount defect parts immediately and repair them or send them to repair.
6. Preparation for winter time
Before winter the pipe system and the pumping station are to be drained. The drainage valve
must be open until the next in commissioning.
By sprinklers with a stop valve (H), the water above the stop valve cannot discharge itself.
Because of that reason the sprinkler insert of the installation are to be lift on the cover ( e.g. for
winterising). When the sprinkler insert are lift, the water can flows out off the guiding housing
and air can enter into the conductions.
Therefore it is the best to put a piece of wood with approximately 2 cm between cover and
housing until the installation is empty.

7. Troubleshooting + Solutions
Attention !!!
Before above-mentioned works are executed, it must be ensure
that the valve is pressure-less.
In case of less casting range of some sprinklers it might be garbage in the filter.
Then you must dismount the sprinkler insert and clean the filter.
Flushing the pipe
Only with flushing insert, otherwise the water which flows back can take garbage with it in the
housing and can than enter to the pipe system.
8. Disassembly and assembly of sprinklers
That work can be done with help of standard tools.
Disassembly
Unscrew slot screws in the cover.
Remove screw / nut and pull out sprinkler insert
Assembly
Tighten sprinkler insert with screw / nut
Mount cover with screws and retainer for cover
