8.2 Disassembly
The Mirage M-‐125 / M-‐115 series sprinklers are designed to be fully serviceable from the
top of the sprinkler and therefore do not always require complete removal from an
installation for servicing.
Disassembly of the Mirage sprinkler series should be done in a valve box where backfill has
been previously removed and set to the side for replacement once servicing has been
completed. This is to avoid loose debris from falling down into the exposed portions of the
sprinkler body.
To avoid injury, the mainline or sub-‐lateral should be de-‐pressurized prior to
working on a Mirage valve-‐in-‐head sprinkler series.
1)
Locate and unscrew the 2 (qty) slotted-‐head fasteners that secure the cover to the
impact drive subassembly. Set the lid, the 2 (qty) fasteners and brass-‐threaded plate to
the side.
2)
Locate and unscrew the slotted-‐head fasteners that secure the impact drive assembly to
the lower portion of the sprinkler body. Set the fasteners to the side and carefully lift
the impact drive assembly out of the sprinkler body. The same fasteners that secure the
internal impact drive assembly also secures the upper portion of the sprinkler body to
the lower portion.
3)
The upper portion of the sprinkler body also houses the valve solenoid and filters.
Unscrew the solenoid counter-‐clockwise to remove from the sprinkler body. There is a
white and black filter located directly below the threaded inlet. Carefully remove the
filters and verify both are clean of any debris.
4)
Locate the white snap ring in the bottom of the lower sprinkler body. Using service
tools, p/n RTC4 17839 and p/n RZG2 17844 remove the snap ring.
5)
To remove the foot valve, thread the valve sleeve tool p/n RZK2 17843 into the valve
insert. Loosen the valve insert by applying slight blows upwards with the sleeve around
