Installation
Model F1 LO sprinklers are standard response sprinklers in-
tended for installation as specied in NFPA 13. They must also
be installed with the Model W2 Sprinkler Wrench specically
designed by Reliable for use with these sprinklers.
The Model F1 LO Recessed Sprinklers are to be installed with
a maximum recess of ¾ inch (19mm). The Model F1 Escutch-
eon illustrated is the only recessed escutcheon to be used with
the Model F1 LO Pendent and EC Sprinklers. The use of any
other recessed escutcheon will void all approvals and negate
all warranties. When installing Model F1 LO Recessed Pendent
and EC Pendent Sprinklers, use the Model GFR2 Sprinkler
Wrench. Any other type of wrench may damage these sprin-
klers. Note: A leak tight 3/4” NPT (R/4) sprinkler joint can be
obtained with a torque of 14 - 20 ft-lbs (19 - 27 N-m). Do not
tighten sprinklers over maximum recommended torque. It may
cause leakage or impairment of the sprinklers.
Glass bulb sprinklers have orange covers to protect the bulb
during the installation process. REMOVE THIS PROTECTION
ONLY AFTER THE SYSTEM HAS BEEN HYDROSTATICALLY
TESTED AND, WHEN APPLICABLE, THE ESCUTCHEONS
HAVE BEEN INSTALLED. RASCO wrenches are designed to
install sprinklers when covers are in place.
Maintenance
The Models F1 LO sprinklers should be inspected 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 which has been painted
(other than factory applied) or damaged in any way. A stock of
spare sprinklers should be maintained to allow quick replace-
ment of damaged or operated sprinklers. Prior to installation,
sprinklers should be maintained in the original cartons and
packaging until used to minimize the potential for damage to
sprinklers that would cause improper operation or non-oper-
ation.
