WARNINGS
The Model F993 Aquarius
RES/QR-EC/EC Horizontal Side-
wall Sprinklers described herein
must be installed and maintained
in compliance with this docu-
ment, as well as with the applica-
ble standards of the National Fire
Protection Association, in addi-
tion to the standards of any other
authorities having jurisdiction.
Failure to do so may impair the
integrity of these devices.
Because of the above cited stipu-
lations and the varied nature of
residential type architecture,
there will be some compartment
designs which cannot be fully
sprinklered in accordance with
the recommendations of NFPA 13,
13D, or 13R. In the event of this
condition, consult the authorities
having jurisdiction for guidance.
It is the responsibility of an in-
stalling contractor to provide a

in turn, it is the obligation of the
owner to provide a copy of this
document to a succeeding owner.
The owner is responsible for
maintaining their fire protection
system and devices in proper op-
erating condition. The installing
contractor or sprinkler manufac-
turer should be contacted relative
to any questions.
GENERAL TECHNICAL DATA
Sprinkler Assemblies:
The 5.6 K-Factor, Model F993 Aquar-
ius RES/QR-EC/EC Horizontal Side-
wall Sprinklers are available in a
160°F/71°C temperature rating and
they are rated for use at a maximum
service pressure of 175 psi. They are
available with a chrome, white, or
bright brass finish. Escutcheon Plates
are available with various finishes and
are ordered separately, as indicated in
the following sub-section.
The F993 is shipped with a plastic Pro-
tective Cap covering the outside of the
Fusible Element and the outer portion
of the Body. The Protective Cap can
be left in position while the Sprinkler is
being installed and then it is slid off
once the wall installation is complete
and the sprinkler system is ready to be
put into service.
The nominal flow “Q” in GPM (LPM) is
determined by the following formula:
Q = K (p
1/2
)
where the nominal sprinkler discharge
coefficient “K” equals 5.6 (80,6); and
“p” equals the residual pressure in psi
(bar).
The Body is bronze per ASTM B584
(C83600 or C84400) and the Dust Cap
is polyolefin. The Heat Collectors are
copper per ASTM B152 (C11000) and
the Inner & Outer Loading Plates and
Spacer are brass per ASTM B16
(C36000) or ASTM B140 (C31400 or
C31600). The Loading Screw and two
Arms are Type 302 stainless steel per
ASTM A276 or Type 303 per ASTM
A582. The Disc Spring is a chrome
plated high strength carbon steel and
the Retaining Ring is titanium per
ASTM B348 (Grade 5). The Gasketed
Button-Deflector consists of brass but-
ton per ASTM B16 (C36000), brass
deflector per ASTM B36 (C22000),
and a Teflon
†
gasket.
Escutcheon Plates:
The following are the two types of es-
cutcheon plates that may be used with
the F993 Aquarius Sprinkler:
•
Push-on Escutcheon Plate
•
Push-on Escutcheon Plate with Ex-
tension
Figures C and D illustrate typical in-
stallations of an F993 using a Push-on
Escutcheon Plate and using a Push-on
Plate with Extension. The Push-on Es-
cutcheon Plate provides a total of 1/4
inch of horizontal adjustment and it is
installed by simply slipping it over the
F993 Body; however, when it is used
in conjunction with the Extension, an
additional 1/4 inch of adjustment can
be obtained for a total of 1/2 inch of
horizontal adjustment.
When using the Push-on Plate with
Extension, the installer simply deter-
mines the approximate distance from
the wall mounting surface to the out-
