INSTALLATION
The 5.6 K-Factor, Model PH-5 Sprinklers must be in-
stalled in accordance with the following instructions:
NOTES
Refer to the Design Criteria section for important informa-
tion regarding the piping installation design and its affect
on maintaining the integrity of the tamper resistant design
of the Institutional Escutcheons.
A leak tight 1/2 inch NPT sprinkler joint should be ob-
tained with a torque of 7 to 14 ft.lbs. (9,5 to 19,0 Nm). A
maximum of 21 ft.lbs. (28,5 Nm) of torque is to be used to
install these sprinklers. Higher levels of torque may dis-
tort the sprinkler inlet with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for improper location of
the sprinkler fitting by under- or over-tightening the Sprin-
kler. Readjust the position of the sprinkler fitting to suit.
After the installation is complete, make certain that the In-
stitutional Escutcheon is held fast to the mounting sur-
face and that it sits squarely against the wall around its
entire perimeter.
1. The Model PH-5 Sprinklers must be installed with the
centerline of their waterway horizontal and perpendicu-
lar to the back wall surface, and the Deflector must be lo-
cated with the top towards the ceiling (Ref. Figure 1).
2. With the Institutional Escutcheon in place and with pipe
thread sealant applied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
3. Wrench tighten the Sprinkler using only the #1509-1 or
#1509-3 Sprinkler Wrench (Ref. Figure 4). The wrench-
ing teeth of the Sprinkler Wrench are to be applied to
the sprinkler wrenching notch areas (Ref. Figure 1).
4 After the installation is complete, make certain that the
Institutional Escutcheon is held fast to the mounting sur-
face and that it sits squarely against the wall around its
entire perimeter.
NOTE
The Sprinkler Body must not extend beyond the Institutional
Escutcheon (Ref. Figure 5). Otherwise the tamper resistant
design of the Model PH-5 will be compromised.
CARE AND MAINTENANCE
The 5.6 K-Factor, Model PH-5 Sprinklers must be main-
tained and serviced in accordance with the following in-
structions:
NOTES
Service inspections should be made on a regular basis to
detect possible damage or alterations to the sprinkler and
escutcheon. Inspections should include making certain
that the Institutional Escutcheon is held fast to the mount-
ing surface. Damaged or altered sprinklers are to be re-
placed immediately to avoid personal injury and to pre-
vent use for causing personal injury, as well as to
maintain the sprinkler system in an operative condition.
Before closing a fire protection system main control valve
for maintenance work on the fire protection system which
it controls, permission to shut down the affected fire pro-
tection systems must be obtained from the proper authori-
ties and all personnel who may be affected by this action
must be notified.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperatures will exceed 100°F/38°C and
they must never be painted, plated, coated, or otherwise
altered after leaving the factory. Modified or over-heated
sprinklers must be replaced.
