FLUSH PENDENT SPRINKLERS, RESIDENTIAL
MODEL F990 AQUARIUS@‘, 4.2 K-FACTOR
The 4.2 K-factor, Model F990 Aquarius
Residential Pendent Sprinklers (Ref.
Figure A) are automatic sprinklers of
the fusible solder type. They are low
profile, flush mounting sprinklers
which are intended to be used in
. wet pipe residential sprinkler sys-
tems for one- and two-family dwell-
ings and mobile homes per NFPA
13D,
. wet pipe residential sprinkler sys-
tems for residential occupancies up
:p,;Tnitories in height per NFPA
. wet pipe sprinkler systems for the
residential portions of any occu-
pancy per NFPA 13.
Small and attractive, the F990 Sprink-
lers are installed with either a Push-on
or Clamp-on Escutcheon Plate and
feature a smooth, low profile, flush-
style design with an aesthetically
pleasing appearance that blends in
with all types of surroundings.
The Push-on Escutcheon Plates, as
described in the Technical Data sec-
tion, are intended primarily for use with
steel pipe or copper tubing. The l/4
inch adjustment provided by the Push-
on Escutcheon Plate and the addi-
tional l/4 inch of adjustment that can
be obtained by use of the Extension
reduces the accuracy to which the
sprinklers must be positioned. The 3
inch outside diameter of the Push-on
Plate also contributes to the ease of
installation by covering offset clear-
ance holes.
Clamp-on Escutcheon Plates, which
are designed for use with plastic pipe
fire protection systems, are described
in Technical Data Sheet TD810.
The F990 Sprinklers have been de-
signed to operate with a particular fus-
ible element temperature rating and
heat sensitivity characteristic, as well
as to discharge water in a specific pat-
tern and quantity per square foot rela-
tionship. The combination of. the per-
formance characteristics which are
associated with the F990 Sprinklers
have been proven to help in the control
of residential type fires and, therefore,
to improve the chance for occupants to
escape or be evacuated.
Fire sprinkler systems are not a substi-
tute for intelligent fire safety aware-
ness or construction materials and
practices required by building codes.

WARNINGS
The Model F990 Aquarius Resi-
dential Pendent Sprinklers de-
scribed herein must be installed
and maintained in compliance
with this document, as well as
with the applicable standards of
the National Fire Protection As-
sociation, in addition to the stan-
dards 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
and approval.
It is the responsibility of an in-
stalling contractor to provide a
copy of this document to the owner
or his representative and, 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.
Sprinkler Assemblies:
The 4.2 K-factor, Model F990 Aquarius
Residential Pendent Sprinklers are
available in a 16O’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. Escutch-
eon Plates are available with various
finishes and are ordered separately,
as indicated in the following sub-sec-
tion.
The F990 is shipped with a plastic Pro-
tective Cap covering the outside of the
Fusible Element and the lower 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 ceiling installation is com-
plete and the sprinkler system is ready
to be put into service.
The nominal discharge curve for the
F990 is plotted in Figure B and it rep-
resents the flow “Q” in U.S. gallons per
minute (GPM) as determined by the
formula:
Q=K$
where the nominal sprinkler discharge
coefficient “K” = 4.2, and “p” = pres-
sure in pounds per square inch (psi).
Listing standards permit the actual
value of K to vary from 4.0 to 4.4.
The Body is bronze per ASTM 8584
(C83600 or C84400) and the Dust Cap
is polyolefin. The Heat Collectors are
copper per ASTM 8152 (Cl 1000) and
the Inner & Outer Loading Plates are
brass per ASTM B16 (CSSOOO) or
ASTM 8140 (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 Retain-
ing Ring is titanium per ASTM 8348
(Grade 5). The Gasketed Button-De-
flector consists of a brass button per
ASTM B16 (CSSOOO), brass deflector
per ASTM B36 (C22000), and a Tef-
lonf gasket.
Escutcheon Plates:
The following are the three types of
escutcheon plates that may be used
with the F990 Aquarius Sprinkler:
9 Push-on Escutcheon Plate
l Push-on Escutcheon Plate with Ex-
tension
l Clamp-on Escutcheon Plate
Figures C and D illustrate typical in-
stallations of an F990 using a Push-on
Escutcheon Plate and using a Push-on
Plate with Extension. The Push-on Es-
-2-
cutcheon Plate provides a total of l/4
inch of vertical adjustment and it is
installed by simply slipping it over the
F990 Body; however, when it is used
in conjunction with the Extension, an
additional l/4 inch of adjustment can
be obtained for a total of l/2 inch of
vertical adjustment.
When using the Push-on Plate with
Extension, the installer simply deter-
mines the approximate distance from
the ceiling mounting surface to the bot-
tom of the Heat Collector. The Exten-
sion is used when this distance (Ref.
“D” in Figure D) is greater than 7/8 inch
and, the Extension is discarded for dis-
tances of 718 inch or less.
The Push-on Escutcheon Plate and
Extension are formed from low carbon
sheet steel and they are available with
a chrome, white, or bright brass finish.
Also a color finish other than white can
be provided.
The Clamp-on Escutcheon Plates are
suitable for use with plastic pipe fire
protection systems when they are in-
stalled in accordance with the instruc-
tions given in Technical Data Sheet
TD810.
NOTE
The Push-on Escutcheon Plates
shown in Figures C and D can
NOT be used to hold the F990 in
position. The F990 must be se-
cured inposition by firmly fasten-
ing the sprinkler system piping to
the dwelling structure. If theF990
is not properly secured in posi-
tion, reaction forces resulting
from sprinkler operation could
alter its orientation and water
distribution pattern.
The 4.2 K-factor, Model F990 Aquarius
Residential Pendent Sprinklers must
only be installed and utilized in accor-
dance with the following described cri-
teria which are provided by the manu-
facturer.
NOTES
1. Residential Fire Sprinkler Sys-
tems should only be &signed
and installed by those compe-
tent and completely familiar
with automatic sprinkler sys-
tem design, installation proce-
dures, and techniques.
2. Several criteria may apply to
the installation and usage of
each sprinkler. Consequently,
it is recommended that the
sprinkler system designer re-
view and develop a working un-
derstanding of the complete
t DuPont Registered Trademark
OBSOLETE

list of criteria, prior to initiat-
ing the design of the sprinkler
system
3. Question8 concerning sprink-
ler installation and usage cri-
teria, which are not covered by
the following instructions,
should be mailed to the atten-
tion of the Technical Data De-
partment. Include sketches
and technical details, as ap-
propriate.
4. In some instances, the nsquire-
ments of this document may
concern specifications which
are more stringent and which
take precedence over those
specified in NFPA 13, NFPA
130, NFPA 13R, or by the au-
thority havingjurisdiction.
5. The spray from the F990 is dis-
tributed radially outward and
downward from the sprinkler
deflector. Consequently, the
sprinkler8 must be located
such that there will not be any
blind spaces shielded from
spray by partitions, mom di-
viders, overhangs or other
parts of the dwelling structure.
General Service Conditions. The
F990 Sprinklers must only be utilized
in wet pipe sprinkler systems with all
interconnecting system piping as well
as the sprinklers maintained at a mini-
mum temperature of 4O’F/4’C, and
with water supplies which are substan-
tially free of contaminants and
particles of a size greater than 118
inch.
Hydraulic Design Criteria. The mini-
mum required single and multiple
DISCHARGE IN U.S. GALLONS PER MINUTE IGPM,
DISCHARGE IN LITERSPER ,,,lNU’~i
FIGURE B
NOMINAL DISCHARGE CURVE
sprinkler flow rates are given in Table
A for the maximum allowable coverage
areas. The single sprinkler flow rate is
the minimum required discharge from
the most hydraulically demanding sin-
gle sprinkler and, the multiple sprinkler
flow rate is the minimum required dis-
charge from each of the total number
of “design sprinklers” (as specified in
NFPA 13, 13D, or 13Fi).
NOTE
The number of sprinklers within
each compartment (as defined by
NFPA 13, 130, or 13R), must be
kept as few as possible. Do NOT
use more sprinklers than neces-
sary to cover a particular space.
Spray Coverage Criteria. Figures E
and F provide spacing rules that must
be followed to assure that the F990
Sprinklers will provide their design dis-
tribution of water spray. Nominal wet-
ting patterns for the F990 Sprinklers at
minimum required flow conditions
(Ref. Table A), are illustrated in Figure
G, for selected coverage areas.
Operational Sensitivity Criteria. For
proper operational sensitivity, the
F990 Sprinklers must be installed be-
neath solid ceilings having a smooth or
textured. surface and in the flush
mounted, pendent position with a bot-
tom of Heat Collector (Ref. Fig. A) to
ceiling distance of between 510 and 4
inches. Figures E and F provide re-
quirements necessary for the proper
operational sensitivity of the F990
Sprinklers.
The F990 Sprinklers must NOT be
used above or below open-gridded
type suspended ceilings; beneath sof-
fits or beams having a depth of more
than 3 inches; and, with beams, joists,

3 inches located within the sprinkler
coverage areas.NOTE
Beam8 having a height of more
than 3 inches may be located with
their centerlines along the bound-
aries separating adjacent sprink-
ler coverage areas.
It is recommended that as part of the
sprinkler system design, the designer
review the dwelling plans and, where
appropriate, advise the owner or his
representative as to the following.
I. Lintels of at least 3 inches in height
and preferably 8 inches should be
used over all passageways from one
space to another, in order to reduce
the possibility of sprinkler operations
outside of the fire area.
II. Beams of at least 3 inches in height
should be used to border each of 5
or more adjoining areas of F990
Sprinkler coverage (within the same
compartment), in order to decrease
the time to first sprinkler operation as
well as to reduce the possibility of
multiple sprinkler operations.
Cold Soldering Criteria. Figures E
and F provide the minimum spacing
requirements necessary for prevent-
ing the wetting (i.e., cold soldering) of
the Fusible Element Assembly of a
non-operated F990 Sprinkler, which is
adjacent to one which has operated.
Heat Source Criteria. Refer to NFPA
13D for the requirements relating to
preventing the weakening followed by
the possible release of an F990
Sprinkler Fusible Element Asembly,
due to exposure to heat sources other
than abnormal fire.

NOTES
Residential Fire Sprinkler Sys-
tems should only be designed and
installed by those competent and
completely familiar with au-
tomatic sprinkler system design,
installation procedures, and
techniques.
The Technical Data Department
should be contacted relative to
any questions.
The Model F990 Aquarius Pendent
Residential Sprinklers must be in-
stalled in accordance with the follow-
ing instructions:
1. The Sprinkler must only be installed
in the pendent, flush mounted posi-
tion and with the threaded end per-
pendicular to the mounting surface.
2. When using the Push-on Escutch-
eon Plate shown in Figure C, the
pipe connected to the sprinklerfitting
should be cut so that the “A” dimen-
sion is between 1 and l-1/8 inches.
When using the Push-on Escutch-
eon Plate with Extension shown in
Figure D, the pipe connected to the
sprinkler fitting should be cut so that
the “A” dimension is between 13/l 6
and i-1/16 inches. In either case,
the remaining portion of the adjust-
ment can be used to help compens-
ate for the possible manufacturing
variations in the make-in of the
Sprinklers and the take-out of the
fittings (as permitted by ANSI
81.20.1).
Refer to Technical Data Sheet
TD810 for installation information on
the Clamp-on Escutcheon Plate
which is suitable for securing the
Sprinkler to its mounting surface in
plastic pipe fire protection systems.
NOTE
The Push-on Escutcheon Plates
shown in Figures C and D can
NOT be used to hold the Sprink-
ler in position. The Sprinkler
must be secured in position by
firmly fastening the sprinkler
system piping to the dwelling
structure.If theSprinkler is not
properly secured inpoeition, re-
action forces resulting from
sprinkler opemtion could alter
itsorientation and water distri-
butionpattern.
3. Use only a non-hardening type of
Teflont based pipe joint sealant and
apply it sparingly to the male threads
only.
4. Hand tighten the Sprinkler with the
attached Protective Cap (as
shipped), into the sprinkler fitting.
5. Using the Model F873 Sprinkler
Wrench shown in Figure H, tighten
the Sprinkler into the fitting.
The Wrench is slipped over the Pro-
tective Cap and can be mounted to
a l/2 inch socket drive ratchet. A
radial force of 10 to 18 Ibs. applied
to atypical 9 inch long ratchet handle
will exert the 7 to 14 ftlbs. of torque
required for a leak tight sprinkler
joint.
NOTES
Amaximumof21ft.lbs.oftorque
is to be used to install the
sprinkler. Higher levels of
torquemay distort thesprinkler
orifice seat with consequent
leakage.
All sprinklers installed within
compartments in which the
sprinklers are only located on a
level ceiling must be installed
with their wrench lugs aligned
parallel to a straight compart-
ment walL
All sprinklers installed within
compartments having apitched
ceiling with one or twoparallel
horizontal ceiling ridges must
be installed with their wrench
lugs alignedpamllel to theceil-
ing ridges.
Failure toproperly orientate the
sprinkler wrench lugs may re-
sult in impaired fire protection
due to cold soldering and/or in-
adequate spray coverage
6. Do not remove the Protective Cap at
this time. The Protective Cap is’ in-
tended to help protect the sprinkler
until the ceiling finish is complete
and the sprinkler system is ready to
be put into service.

NOTE
Failure to use the Protective
Cap, while the ceiling installa-
tion is being completed, can re-
cultintheaccidental damage or
painting of a sprinkler. Dam-
aged orpainted sprinklersmust

After the ceiling finishing is complete
and the sprinkler system is ready to
be put into service, slide off the Pro-
tective Cap.
NOTE
Failure toremove theProtective
Cap will prevent proper opem-
tion of the Sprinkler:

on the inside edge of the Push-on
Escutcheon Plate with the Wrench
Lugs on the Sprinkler Body and then
push the Escutcheon Plate over the
Body of the Sprinkler until its outside
edge comes in contact with the
mounting surface.
When using the Push-on Plate with
Extension, first determine the dis-
tance from the ceiling mounting sur-
face to the bottom of the Heat Col-
lector. If the dimension is 7/8 inch or
less, discard the Extension and pro-
ceed to install the Push-on Plate as
indicated above. If the dimension is
greater than 7/8 inch, assemble the
Extension to the Push-on Plate and
then proceed to install the assembly
as indicated above.

ing the factory. Modified or over-
heated sprinklers must be replaced.
NOTE
Particular care to prevent over-
heating must be exercised when
storing sprinklers in cars, trucks,
trains, or other vehicles on warm,
bright sunny days.
Care must be exercised to avoid dam-
age to the F990 Sprinklers - both be-
fore and after installation. Sprinklers
damaged by dropping, striking,
wrench twist/slippage, orthe like, must
be replaced.
NOTES
Absence of an Escutcheon Plate
may delay the time to sprinkler
operation in a fire situation.
Before closing a fire protection
system main control valve for
maintenance work on the firepro-
tection system which it controls,
permission to shut down the afi
fected fire protection systems
must be obtained from the proper
authorities and allpersonnel who
may be affected by this action
must be notified.
It is recommended that automatic
sprinkler systems be inspected
and maintained in accordance
with the advice and suggestions
given in NFPA 13, 13A, 130, and
13R, as applicable.
It is recommended that automatic
sprinkler systems be inspected quar-
terly by a qualified Inspection Service.
The F990 Sprinklers must only be re-
placed with pendent sprinklers which
are listed for residential fire protection
service and which have the same nom-
inal K-factor, the same coverage area,
the same or lower flow ratings (as indi-
cated under “Hydraulic Design Cri-
teria”), and the same or higher temper-
ature rating.
All residential sprinklers installed
within a compartment as defined by
the NFPA must be made by the same
manufacturer and have the same type
of heat responsive element and tem-
perature rating.
NOTES
Wet pipe sprinkler systems must
be maintained at a minimum tem-
perature of 4OFl4C. Exposure to
freezing temperatures can result
in bursting of the pipe andlor
sprinkler.
Do NOT enclose sprinklers within
drapes, curtains, or valances.
Do NOT hang anything from the
sprinklers.
Automatic sprinklers are NOT to
be tested with a heat source.
Weakening or operation of the
Fusible Element Assembly can re-
sult.
Do NOT cleanse the sprinklers
with soap and water, detergents,
ammonia, cleaning fluids, or
other chemicals. Remove dust,
lint, cobwebs, cocoons, insects,
and larvae by gently brushing
with a feather duster or gently
vacuuming with a soft bristle (i.e.,
dusting) brush attachment.
The minimum vertical clearance
between the tops of free standing
partitions, room dividers, cab-
inets, storage racks, stock piles,
etc., and the centerline of the
sprinkler waterway is NOT-to be
less than the clearance given
below.

Exercise suitable safety precau-
tions in the use and storage of
highly flammable and potentially
explosive materials. The rapid
rate of fire development and
spread which can be caused by
such materials can reduce the
ability of the sprinkler system to
aid in the control of a fire in
which they are involved. s
When remodeling, such as by adding
false beams or light fixtures or chang-
ing the location of compartment walls,
first verify that the new construction
will not violate the installation require-
ments stated under WARNINGS. Alter
the new construction and/or the sprink-
ler system to suit the requirements of
this document.
