the lifting tool. Remove the foot valve and inspect the inlet screen. Clean any debris
that may have collected in the bottom of the foot valve filter screen.
8.2 Re-‐Assembling the Sprinkler
Prior to re-‐assembling the sprinkler, flush the sub-‐lateral line thoroughly. Securing the
upper and lower portions of the sprinkler body with the fasteners and using the special
flushing tool p/n RZG2 17623 (shown as 31 in the Figure 8-‐1 below), can accomplish this
task.

1)
Locate the foot valve and thread into the valve sleeve tool p/n RZK2 17623. Insert into
the lower sprinkler body with the chamfered surface pointing downward. Grease the
rubber edges to ease of insertion.
2)
Align the valve insert with manual control device or ventilating screw, as the foot valve
is set into place. This may require some slight downward blows with the sleeve tool to
seat into place.
3)
Replace the retaining snap ring by placing into the groove with the snap ring tool p/n
RTC4 17839. If the snap ring will not seat properly, confirm the foot valve is seated
properly. This may require the foot valve to be removed and re-‐seated.
4)
Align the impact drive subassembly with its guide pins in any small groove. Press into
place and secure with the stainless steel fasteners. Tighten in a star pattern to set to
secure properly.
