INSTALLATION
NOTE
A leak tight 3/4 inch NPT sprinkler
joint should be obtained with a torque
of 10 to 20 ft.lbs. (13,4 to 26,8 Nm). A
maximum of 30 ft. lbs. (40,7 Nm) of
torque may be used to install sprin-
klers with 3/4 NPT connections.
Higher levels of torque may distort the
sprinkler inlet with consequent leak-
age or impairment of the sprinkler.
The Model FR-1 QR-EC/EC Horizontal
Sidewall Sprinklers must be installed
in accordance with the following in-
structions.
1. Horizontal sidewall sprinklers are to
be installed with their centerline of
waterway perpendicular to the back-
wall and parallel to the ceiling. The
top of the deflector is to face towards
the ceiling. It is recommended that a
lightweight spirit level be used to
level the sprinkler fitting, as applica-
ble, and the deflector as shown in
Figure B.
2. With pipe thread sealant applied to
the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
3. Tighten the sprinkler into the sprin-
kler fitting using only the W-Type 11
Sprinkler Wrench (Ref. Figure C).
The wrench is to be applied to the
sprinkler wrenching area shown in
Figure A.

(a) For use in Light Hazard Occupancy automatic sprinkler system applications per Factory Mutual Loss Prevention Data Sheet 2-8N
(QR-EC is quick response - extended coverage).
(b) The centerline of the sprinkler waterway is located 7/16 inch (11,1mm) below the deflector (Ref. Figure A).
(c) Ceiling is to slope downwards from the wall on which the sprinkler is located.
