USE ONLY the designated sprinkler wrenches shown in this document. Permanent damage to the
sprinkler assembly can occur if the proper wrench is not used. Other sprinkler wrenches available from
Viking may fit into the sprinkler adapter cup; however, only the wrenches shown here are designed to
properly install this sprinkler.
Step 2:
Rotate the wrench slightly in either direction
until the tines on the wrench (D) line up with
the vent openings (E) on the adapter cup and
lock into place. NOTE: A leak tight seal must
be achieved. Turn the sprinkler clockwise
