INSTALLATION
NOTE
Residential Fire Sprinkler Sys-
tems should only be designed and
installed by those competent and
completely familiar with auto-
matic sprinkler system design, in-
stallation procedures, and tech-
niques.
The Model F993 Aquarius RES/QR-
EC/EC Horizontal Sidewall Sprinklers
must be installed in accordance with
the following instructions.
1. The Sprinkler must only be installed
in the sidewall, flush position with the
centerline of the waterway horizon-
tal and perpendicular to the mount-
ing surface.
NOTE
It is recommended that a spirit
level be used to level the sprin-
kler fitting as shown in Figure F
and that a square be used to
check perpendicularity of the
waterway centerline to the
mounting surface.
2. When using the Push-on Escutch-
eon Plate shown in Figure C, the
pipe connected to the sprinkler fitting
should be cut so that the “A” dimen-
sion is between 1 and 1-1/8 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 13/16
and 1-1/16 inches. In either case,
the remaining portion of the adjust-
ment can be used to help compen-
sate for the possible manufacturing
variations in the make-in of the
Sprinklers and the take-out of the
fittings (as permitted by ANSI
B1.20.1).
NOTE
The Push-on Escutcheon Plates
shown in Figures C and D can
NOT be used to hold the Sprin-
kler in position. The Sprinkler
must be secured in position by
firmly fastening the sprinkler
system piping to the dwelling
structure. If the Sprinkler is not
properly secured in position, re-
action forces resulting from
sprinkler operation could alter
its orientation and water distri-
bution pattern.
3. With pipe thread sealant applied to
the pipe threads, hand tighten the
Sprinkler with the attached Protec-
tive Cap (as shipped), into the sprin-
kler fitting.
4. Using the Model F873 Sprinkler
Wrench shown in Figure G, tighten
the Sprinkler into the fitting. The
word “TOP” on the Deflector Hat
must face upwards towards the ceil-
ing.
The Wrench is slipped over the Pro-
tective Cap and can be mounted to
a 1/2 inch socket drive ratchet. A
radial force of 10 to 18 lbs. applied
to a typical 9 inch long ratchet handle
will exert the 7 to 14 ft.lbs. of torque
required for a leak tight sprinkler
joint.
NOTES
It is recommended that a spirit
level be used to level the Deflec-
tor Hat, as shown in Figure F.
A maximum of 21 ft.lbs. of
torque is to be used to install the
sprinkler. Higher levels of
torque may distort the sprinkler
orifice seat with consequent
leakage.
5. Do not remove the Protective Cap at
this time. The Protective Cap is in-
tended to help protect the sprinkler
until the wall finish is complete and
the sprinkler system is ready to be
put into service.
NOTE
Failure to use the Protective
Cap, while the wall installation
is being completed, can result in
the accidental damage or paint-
ing of a sprinkler. Damaged or
painted sprinklers must be re-
placed.
6. After the wall finishing is complete
and the sprinkler system is ready to
be put into service, slide off the Pro-
tective Cap.
NOTE
Failure to remove the Protective
NOTES :
1. For a given position within the coverage area, ceiling mounted obstructions must not hang
below the elevation dimension given in the graph.
2. Elevation dimensions are with respect to the top of the Deflector Hat (ref. Fig. A), where
positive (+) dimensions are above the Deflector Hat and negative (-) dimensions are below.
(Reference: the Deflector Hat is 5/8" above the sprinkler centerline of waterway.)
