5.4.1 Handling the TS170 pop-up sprinkler with filled synthetic turf Remove plug so that the lid and the cable shaft cover can be disassembled / assembled see 8.6. WARNING! Do not plug the drainage holes during adhesive bonding of the synthetic turf. 5.4.2 Operating instructions for TS170 pop-up sprinkler with filled synthetic turf Operation of the manual control using an engineered flat-blade screwdriver (.04” x .35”).
5.5 External start using key switch There is a safety circuit with key-operated switch for checking whether any unauthorized people are in the danger zone / area to be watered. The key-operated switch gets fitted 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.
The DBR/Y-6 cable connector kit (article no.: ZH90032) for connecting the control cable to the coil fitted inside the sprinkler. Opening the cover of the cable compartment and attach cable connector. The cables remain in the compartment provided for the purpose and get closed off with the cover for the cable shaft. The electrical connection is thus not exposed to the soil, but is instead protectively integrated inside the sprinkler and accessible again at any time.
Cable plan (schematic only) Toro controller ! Control cable specification: Suitable for underground installation PVC insulated and EPDM sheathed cable, NYY For TS170: NYY 2x2.
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 pressure 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.
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 is set to AUTO (turn screw for 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.
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. fingers) can get jammed if the sprinkler should unexpectedly close. Cover Sprinkler head Safety catch folded out Safety catch folded in Housing No special procedures are needed to set the sprinkler.
6.3 Setting the Arc With this pop-up sprinkler the arc setting is infinitely variable. You can adjust the area to be watered by pulling on the relevant end 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). Pull spring stop apart at both ends only to such extent that they can just be slid off. WARNING! 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 off.
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. Irrigate at reduced speed only if the water is clear. If WARNING! the water is dirty, the regulating screw must remain fully opened.
7. Shut down and preparing for winter For shut down, please turn off 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. The TS170 sprinkler has an automatic emptying system. The 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.
Tighten cover using face spanner ZB98236 and approximately 10Nm of torque. That means, with a lever length of 4”, you need to apply a force of 100N to the spanner. After the third or fourth winter, there should be no further expansion. If the lock screw cannot be screwed in, it will hit a WARNING! piston drive bracing rib. In this case, the grey cover must be tightened a bit more so that the lock screw misses the bracing rib. The orientation of the bracing ribs is indicated by marker points.
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 • • • • After one year of use, tighten the M6 flange screws (8 of them) using a 10mm box spanner to ensure that the sprinkler module is fixed firmly in place. Tightening torque 9 +1Nm. Clean out the inside of the sprinkler housing using an industrial vacuum cleaner or similar (as necessary).
When changing the main nozzle the nozzle’s thread should be cleaned and greased. This enables the nozzle to be easily loosened by hand (using the assembly key RB25189) and just as easily tightened again. When fitting the nozzle make sure that the funnel gets pushed on in the right position. (See picture.) wrong position correct position If the funnel is not properly fitted first, the nozzle cannot be screwed into the manifold head.
8.3 Removing the Valve Insert The sprinkler module needs to be taken out of the housing in order to carry out the repairs described below. • • Unscrew cover using 5mm Allen key. Remove the 8 flange screws using a 10mm box spanner Flange screw tightening torque: 9+1 Nm 22 • Pull sprinkler module out of the housing. • Remove retaining ring in the housing bottom using removal hook RT17839. • Screw valve lifter RT25359 in the housing base onto the valve and pull upwards.
8.4 Fitting the valve insert • • • • • • • Fitting the valve using valve lifter RT25359. Prior to fitting, check valve for any damage to the membrane. Check for any dirt and clear away. Screw the valve insert with the stainless steel onto the valve lifter. The chambered surface of the stainless steel must point to the valve insert. The valve insert must be greased slightly at the sealing beads and before it is pushed back into the housing.
• When replacing the control unit, cut off the hoses as close as possible to the unit’s grommet. Control unit Fitting the control unit • When buying a replacement part, the control unit is supplied with plug-and-socket connections. Push hoses into plug-in grommets as far as they will go and ensure that the mounting ring springs back. WARNING! 24 Please ensure that the hoses are fitted in the correct position. Otherwise the sprinkler will not work. • Otherwise the sprinkler will not work.
9. Troubleshooting 9.1 Sprinkler malfunctions Malfunction Cause Dirty water. Sprinkler not rotating or only very Speed regulator set to minimum. slowly. Blocked Sprinkler not rotating at all. Defective piston drive Sprinkler has poor jet Nozzle / funnel is blocked Arc angle gets bigger during operation. Spring stop is loose. Spring force has slackened. Spring stop has been overextended.
