Model F1 LO and F1 LO
Recessed Sprinklers
Application
Model F1 LO and F1 LO Recessed sprinklers are used in
fixed fire protection systems: Wet, Dry, Deluge or Preaction.
Care must exercised that the orifice size, temperature rating,
deflector style and sprinkler type are in accordance with the
latest published standards of the National Fire Protection
Association or the approving Authority Having Jurisdiction.
Installation
Model F1 LO sprinklers are standard response sprinklers
intended for installation as specified in NFPA 13. They must
also be installed with the Model D Sprinkler Wrench specifically
designed by Reliable for use with these sprinklers.
The Model F1 LO Recessed Sprinklers are to be installed with
a maximum recess of 3/4" (19 mm). The Model F1 Escutcheon
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 sprinklers.
Note: A leak tight 1/2" NPT (R1/2) sprinkler joint can be obtained
with a torque of 8-18 ft-lb (11-24 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 and F1 LO Recessed 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 replacement 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-operation.
