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.
