Toro ACME Installation Instructions

ACME Thread Installation Instructions
The ACME thread golf sprinkler body requires an ACME thread swing joint for connection to the piping system. The ACME swing
joint has an o-ring on the exit fitting that provides a watertight seal inside the sprinkler body when properly assembled.
With the ACME fitting, it is important to note that thread sealants such as Teflon
should not be used during assembly.
Important! For ease of assembly and to ensure proper sealing, moisten the o-ring with clean water just prior to installation.
To Install full-circle sprinklers:
Screw the sprinkler body clockwise onto the ACME swing joint exit fitting until it
stops. No further tightening is required.
To Install part-circle sprinklers:
Screw the sprinkler body clockwise onto the ACME swing joint exit fitting until it
stops. If necessary, adjust the left (fixed) side of the sprinkler arc by turning the body
counterclockwise up to ⁄ turn.

Caution: Leakage between the swing joint exit fitting and the sprinkler body
may indicate that the o-ring is improperly seated, missing, damaged and/or the
sprinkler body is not completely installed.
If leakage is observed, perform the following procedure:
1. Shut off and relieve system water pressure.
2. Remove the sprinkler from the swing joint fitting.
3. Verify that the o-ring is undamaged and is properly seated in the o-ring groove.
(Replace the o-ring if necessary.)
4. Moisten the o-ring with water, reinstall the sprinkler, repressurize the system and
check for leakage.
