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 synthetic turf. Source water should be pre-ltered and free of any coarse or brous
contamination. e water and ambient temperatures must be within the limits specied in the technical
data (see Section 4).
2.3 Clearly improper use
• Operation of the pop-up sprinkler by unauthorized personnel.
• Operation of the sprinkler before the arc has been properly set, or when the arc has been altered
without authorization (e.g., as a result of vandalism). is can result in the water being directed away
from the target irrigation 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.

5. Assembly, set-up and installation
5.1 Hazard warnings
!
If any debris get into the sprinkler, it is possible that the sprinkler could be damaged or
destroyed. Flush out the line thoroughly before connecting the sprinkler to the water supply.
!
Any unexpected incidents at start-up can lead to serious injury from the jet of
water. Make sure the installation has been completed before turning on the
water supply.
5.2 Installation instructions
• e inlet thread connection on the TS120 pop-up sprinkler is 1½" NPT.
• For the thread seal, use a sealing compound and/or material (e.g., Teon tape). Please be sure your
sealing compound of choice is compatible with all materials at the point of connection.
• e pop-up sprinkler should be installed in accordance with the TS120 sprinkler installation diagram
(see next page). In order to avoid any load pressure on the main line, use a recommended Toro
adjustable swing joint or other pressure compatible exible connection.
• Providing a drainage pit directly connected to the drainage, as shown in the installation diagram, is
strongly 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 Wiring
e laid 2-core wire is installed for the electrical connection of the TS120 Impact Sprinkler.
e wire is pulled through the right or left opening on the bottom of the housing into the
solenoid compartment.
Use a Direct Bury Splice Kits (Toro part number
DBRY-100) to connect the control wire to the
solenoid tted inside the sprinkler.
Open the cover of the control module
compartment and connect the solenoid wire.
Use a waterproof connector kit for the connection.
Return the wires into the solenoid compartment
and close the cover.
Use one of the drain holes
to pull the control wires
into the sprinkler.

9
In this installation, the electrical connection is
not exposed to the soil, but is protected inside the
sprinkler and readily top-accessible. is simplies
any search for faults and any maintenance work can
be carried out at any time without digging.

10
6. Start-Up and Operation
6.1 Potential danger
!
At start up, the impact sprinkler rises up out of the housing and builds up full
pressure within about 5 seconds. The jet of water emitted can cause injury. For
this reason, it is critical that all personnel and bystanders are clear of the
irrigation area and are not in the path of the sprinkler’s nozzle opening.
!
If the sprinkler is not installed ush to the ground, it may pose a trip hazard. Prior to startup,
and as a part of regular maintenance checks, ensure the sprinkler cover closes ush with
the sprinkler body.
!
The sprinkler must not be operated without rst closing the cover for the control
compartment. The control compartment cover is an integral component to the proper
operation and rotation of the sprinkler.

6.2 Start-Up Procedure
Be sure to follow the start-up procedure in order, a) to h).
Steps
a) Check electrical function:
Before any water supply to the sprinkler is opened, activate the solenoid by means of the controller.
An audible ‘clicking’ sound from the solenoid is indicative of its functioning properly.
(e click is produced by movement of the plunger.)
b) Ensure the manual control switch (located along the top cover of the rotor) is set to AUTO.
is setting ensures that the sprinkler will retract after the irrigation cycle.
c) Slowly open supply of water to the valve until operating pressure is built up.
It is possible that the sprinkler will briey open, but should then automatically close after at most
30 seconds.
d) Once the water supply has been opened and the operating pressure has been reached,
check sprinkler and connection for leaks.
e) Conrm the sprinkler solenoid is operating properly by toggling the manual control switch between
AUTO and OFF. In between toggles is the ON position--the sprinkler should rise and begin rotating.
!
Do not stand in front of the nozzle opening!
f) Check that the manual control switch is set to AUTO and deactivate solenoid (see point 6.2b).
Sprinkler will stop water ow within 30 seconds.
h) Check once again that it works correctly when activated electrically from the controller.
For Winterization process, see Section 7.

6.3 Arc Setting
• With this impact sprinkler the arc setting is innitely adjustable between 30° and 330°
and capable of a full circle 360°.
• You can adjust the area to be watered by pulling or pressing 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 end of
the top or bottom spring stop.

7. Shut-Down and Preparing for winter
• For winter shut-down, turn o the water supply and electricity supply of the pump.
• During times of possible frost, ensure there is no standing water in the sprinkler.
• e TS120 Impact Sprinkler has an automatic drainage system.
• e sprinkler has a discharge valve and will drain by gravity as long as water drains from the main
pipe. e sprinkler should empty itself.
• Any water that fails to drain from the sprinkler is inconsequential and will not aect the sprinkler in
the event it freezes.
WARNING!
Electrically activate the solenoid several times so that any residual water
is pushed out of the solenoid cavity.
During the winter we recommend activating the solenoid for approx. 1 minute
twice a week.
For Start-up, see section 6.2.

8 Maintenance and Repair Work
!
An unexpected jet of water can cause serious injury. Prior to any maintenance
or repair work ensure that the water supply is securely turned off.
8.1 Maintenance
• Clean out the inside of the sprinkler housing using an industrial wet/dry vacuum cleaner or similar
(as necessary).
• Cut sprinkler housing free of any overgrowing grass. It is recommended this is completed prior to
spring startup.
• Regularly check that the sprinkler is ush with the surface, especially in the case of natural grass.
8.2 Changing the Nozzles
It is recommended that the tools listed in Section 3.3 are used for changing the nozzles.
Use 10mm socket wrench (RT15745) for the driving nozzle and 1” (26mm) socket wrench
for the main nozzle.
8.3 Cleaning or Changing the Valve Insert
e sprinkler module needs to be taken out of the housing in order to carry out the repairs described
in section 8.4.
• Lift the cover and secure the sprinkler module
against snapping back (using a screwdriver or
other brace). Locate the cover clip (see photo)
and pull the clip to release. Remove cover.
• Use a long shank screwdriver to unscrew
the four ange screws at the base of the riser
assembly. (Retain screws.)
Pull sprinkler module out of the housing.
