Product Description
The F1 LO Glass Bulb Sprinkler combines the durability
of a standard sprinkler with the attractive low profile of a
decorative sprinkler. Whether installed on exposed pip-
ing or in an office ceiling, it is functional and attractive.
Beautifully versatile is the description for the Reliable
Model F1 LO Recessed Designer glass bulb sprinkler.
Recessing The Designer®enhances its already low pro-
file decorative appearance, and facilitates a rapid and
perfect installation.
Model F1 LO Recessed Designer’s escutcheon is high-
ly adjustable. The two piece construction makes field
installation a very easy and rapid task. This also allows
ceiling panels to later be removed without shutting down
the fire protection system, thus facilitating maintenance
of above ceiling services.
The Designer®Automatic Sprinkler utilizes a frangible
glass bulb. The glass bulb consists of an accurately con-
trolled amount of special fluid hermetically sealed inside
of a precisely manufactured glass capsule. This glass
bulb is specially constructed to provide fast thermal re-
sponse.
Upright
At normal temperatures, the glass bulb contains the
fluid in both the liquid phase and in the vapor phase. The
vapor phase can be seen as a small bubble. As heat is
applied, the liquid expands forcing the bubble smaller
and smaller as the liquid pressure increases. Continued
heating forces the liquid to push out against the bulb,
causing the glass to shatter, opening the waterway and
allowing the deflector to distribute the discharging wa-
ter.
The F1 LO Sprinkler temperature rating is identified by
the color of the glass bulb capsule as well as frame color
where applicable.

Model F1 LO & 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 rat-
ing, 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 specifi-
cally 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
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 ap-
provals 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-lbs (10.8 - 24.4 N-m). Do not tighten sprinklers over maxi-
mum recommended torque. It may cause leakage or impair-
ment of the sprinklers.
Glass bulb sprinklers have orange covers to protect the
bulb during the installation process. REMOVE THIS PRO-
TECTION ONLY AFTER THE SYSTEM HAS BEEN HYDRO-
STATICALLY TESTED AND, WHEN APPLICABLE, THE ES-
CUTCHEONS 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 ac-
cordance 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 ap-
plied) or damaged in any way. A stock of spare sprinklers
should be maintained to allow quick replacement of dam-
aged 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.
