1. General
We presume that you are experienced in the eld of irrigation. We have therefore kept these instructions
brief and included only the information that it is imperative for you to have to use this product.
Any warranty claims can be accepted only if the sprinkler is used in accordance with these operating
instructions and if any defect emerges within the warranty period.
We reserve the right to make changes in line with technological advances, including without prior notice.
2. Safety
ese operating instructions contain some fundamental instructions that must be followed when
installing, operating, servicing and maintaining the sprinkler. It is therefore imperative that these
instructions are read by the installer and the relevant specialised sta / operators prior to installation and
startup.
Attention must be paid not just to the general safety information set out in this ‘Safety’ section, but also
to the special safety instructions included in the other sections.
2.1. Use of symbols in these operating instructions
Where failure to follow safety information can place individuals at risk, such information is specically
marked in these operating
instructions with the general danger symbol:
!
Warning of potential hand injuries
Warning of potential automatic start-up
In the case of safety information, where failure to follow it can damage the sprinkler and/or impair its
function, you will see the word: WARNING!

2.2 Proper use
e sprinkler is used for the even distribution of water onto lawns, green spaces and sports elds laid with
natural or articial grass. e water should be pre-cleaned and free of any coarse or brous contamination.
e water and ambient temperatures must be below the limits specied in the technical data.
2.3 Clearly improper use
• Operation of the pop-up sprinkler by unauthorised personnel (if the control unit is freely accessible).
• Operation of the sprinkler with the acrc to be watered wrongly set, e.g. as the result of vandalism. is
can result in the jet of water being directed to the side away from the grassed area.
2.4 Safety information
!
Read the operating instructions, especially the safety information, before starting any work
on or with the sprinkler.
e specic safety instructions appear at the start of each section.
2.5 Dangers of failing to observe safety instructions
Failure to observe safety instructions can result both in people being placed at risk and in damage to the
environment and machine. Failure to observe safety instructions can lead to the loss of any rights to claim
compensation.

5. Assembly, set-up and installation
5.1 Hazard warnings
!
If any impurities get into the sprinkler, it is possible that the sprinkler could be destroyed
and that installers could be injured. Flush out the line thoroughly before connecting the
water supply.
!
Any unexpected emergence of a jet of water can lead to serious injury.
Make sure that the installation has been fully completed before turning on the water supply.
5.2 Installation instructions
• e thread connection on the pop-up sprinkler is 2" NPT.
• For the thread seal, use hemp and sealing compound, e.g. Fermit Spezial.
• e pop-up sprinkler should be tted in accordance with the 'TS170 pop-up sprinkler installation
diagram' (see next page). In order to avoid any load pressure on the main line, you should denitely
use a exible connection.
• Providing a drainage pit directly connected to the drainage, as shown in the installation diagram, is
very much recommended.
• For screwing in the connection joint the housing or housing edge of the pop-up sprinkler can be
rmly held or clamped.

5.5 External start using key switch
ere is a safety circuit with key-operated switch for checking whether any unauthorized people are in the
danger zone / area to be watered.
e key-operated switch gets tted in a position from which the whole danger zone can be clearly seen.
Watering begins only when the operator gives the all-clear by turning the key.
5.6 Cabling
3-core cable laid during installation to the TS170 pop-up sprinkler’s electrical connection.
e cable is pulled through the right or left opening on the bottom of the housing into the cable
compartment.

e DBR/Y-6 cable connector kit (article no.:
ZH90032) for connecting the control cable to the
coil tted inside the sprinkler.
Opening the cover of the cable compartment and
attach cable connector.
e cables remain in the compartment provided for
the purpose and get closed o with the cover for the
cable shaft.
e electrical connection is thus not exposed to the
soil, but is instead protectively integrated inside the
sprinkler and accessible again at any time.
is simplies any search for faults and any
maintenance work can be carried out at any time
without any earthwork.

6. Startup and Operation
6.1 Potential danger
!
When it starts up, the pop-up sprinkler rises up out of the housing and builds up full pres-
sure within about 5 seconds. The jet of water emitted can cause injury. For this reason the
following guidance must be followed when and operating the sprinkler:
• When the sprinkler is being operated in automatic mode,
there must be nobody present in the area.
• Operating personnel must not stand in the direction of the sprinkler’s jet. The jet’s
direction is marked on the cover by an arrow.
!
If the sprinkler is not installed ush with the ground, people may be injured by a fall as a
result of stumbling or tripping. Therefore check prior to and regularly during ongoing use
whether the sprinkler cover shuts ush with the surrounding ground.
!
The sprinkler must not be operated without a closed cover for the cable compartment.
During operation the sprinkler head props itself against the edge of the cover and cannot
rotate freely without the cover.

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. (e 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). is 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 briey 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 ow 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.

The following points 6.3, 6.4 and 6.5 should ideally be carried out with the sprinkler
running. First fold out the safety catch to the side of the sprinkler head (below) so that no
limbs (e.g. ngers) can get jammed if the sprinkler should unexpectedly close.
No special procedures are needed to set the sprinkler. All you need to set are the sprinkler’s rotational
speed and, when using it in back-and-forth mode, the arc to be watered.

6.3 Setting the Arc
With this pop-up sprinkler the arc setting is innitely variable.
You can adjust the area to be watered by pulling on the relevant end of the top or bottom spring stop.
Setting the arc angle
WARNING! Innitely variable setting is possible by pulling (not pressing) on the relevant and of
the top or bottom spring stop

6.4 Full-circle irrigation
For full-circle irrigation the spring stops need to be removed.
First, the sprinkler module needs to be removed from the housing.
(See point 8.3).
WARNING!
Pull spring stop apart at both ends only to such extent that they can just be slid off.
If the spring stops get overextended, it will not be possible to use them any more for
back-and-forth operation.
Gently pull both spring stops apart and remove
downwards.
Now splay the spring stops over the sliding pipe
and pull o.
New spring stops are tted in reverse order.
Any overextension of the spring stops must be
avoided, as otherwise it can no longer be certain
that they will t tightly and it will no longer be
possible to set the irrigation arc’s switch-over point
when reverting to arc operation.

17
6.5 Regulating the speed
Turning the regulating screw to the right reduces the rotational speed.
!
It is possible for the sprinkler to be completely stopped when the speed-regulating screw is
turned to the right.
If you turn it to the left, the rotational speed gets increased again.
WARNING!
Irrigate at reduced speed only if the water is clear.
If the water is dirty, the regulating screw must remain fully opened.
Otherwise there is a risk of the sprinkler stopping

7. Shut down and preparing for winter
For shut down, please turn o the water supply and electricity supply of the pump.
7.1 Preparing for winter
During times of possible frost please ensure that there is no standing water in the sprinkler.
e TS170 sprinkler has an automatic emptying system.
e sprinkler has a discharge valve and can thus be emptied by gravity. To do this, the water is let out at
the deepest point of the main pipe, as a result of which the sprinkler empties itself. (Deep point emptying)
e remaining water in the piston drive causes no damage in the event of freezing. If the sprinkler is taken
back into use despite there still being ice in the piston chamber, then, at an ice temperature of approx.
–4°F, it will take around 15 minutes until the drive is thawed out.
WARNING!
Electrically activate the solenoid several times so that any residual water is pushed
out of the coil cavity.
During the winter we recommend activating the coil for approx. 1 minute twice a
week.
7.2 Springtime
As a result of the change of load and diverse installation conditions (damp/dry), the head of the piston
sprinkler is subjected to extreme tensions. ese circumstances can lead to the piston acquiring some axial
play. In order to avoid any operating problems, the piston cover should be tightened as described below
during spring in the rst and second year of operation.
Before the grey cover can be tightened, the lock
screw needs to be removed.
After rmly tightening the grey cover, twist in
the new lock screw again.
!
e lock screw prevents the grey cover from
working itself loose.
