These sprinklers must be installed with a Reliable
Model ZX Sprinkler Wrench. Any other type of wrench
may damage the sprinkler which is designed to allow
wrenching with the shipping cap installed, thereby pro-
viding further protection to the sprinkler. Shipping caps
should be removed only after walls are finished and when
escutcheons are being installed. When Model XL sprin-
klers are ordered, escutcheons and retaining flanges are
included. The Model XL Institutional Escutcheon is the
only escutcheon that can be used with this sprinkler. The
use of any other escutcheon will void all approvals and
negate all warranties. Also, each installed sprinkler must
include an escutcheon.
Use care to avoid damaging the sprinklers before,
during and after installation. Install them according to
Caution Sheet CA-132, and inspect all installed sprin-
klers to insure that they have not been damaged. Re-
place all sprinklers which have any sign of damage.
