Installation
Model F156-300 EC sprinklers are standard response
sprinklers intended for installation as specified in NFPA 13.
They must be installed with the Model D Sprinkler Wrench
specifically designed by Reliable for use with these sprin-
klers.
The Model F156-300 EC Recessed Sprinklers are to
be installed with a maximum recess of ¾” (19mm). The
Model F1, F2, and FP escutcheons illustrated are the only
recessed escutcheons to be used with Model F156-300
EC Pendent Sprinklers. The use of any other recessed es-
cutcheon will void all approvals and negate all warranties.
When installing Model F156-300 EC Recessed Pendent
sprinklers, use the Model GFR2 Sprinkler Wrench. Any
other type of wrench may damage these sprinklers.
Glass bulb sprinklers have orange bulb protectors to
minimize bulb damage during shipping, handling and
installation. REMOVE THIS PROTECTION AT THE TIME
THE SPRINKLER SYSTEM IS PLACED IN SERVICE FOR
FIRE PROTECTION. Removal of the protectors before this
time may leave the bulb vulnerable to damage. RASCO
wrenches are designed to install sprinklers when covers
are in place. REMOVE PROTECTORS BY UNDOING THE
CLASP BY HAND. DO NOT USE TOOLS TO REMOVE
THE PROTECTORS.
Maintenance
The Models F156-300 EC Pendent and Recessed EC
Pendent Sprinklers should be inspected quarterly and the
sprinkler system maintained in accordance with NFPA 25.
Do not clean sprinklers with soap and water, ammonia or
any other cleaning fluid. Remove any sprinkler that has
been painted (other than factory applied) or damaged in
any way. A stock of spare sprinklers should be maintained
to allow quick replacement of damaged or non-operated
sprinklers. Prior to installation, sprinklers should be main-
tained in the original cartons and packaging until used to
minimize the potential for damage to sprinklers that would
cause improper operation or non-operation.
