INSTALLATION
The Model TFP1 must be installed in accordance with the
following instructions:
NOTES
The Protective Cap is to remain on the sprinkler dur-
ing installation and until the ceiling installation is
complete. The Protective Cap must be removed to
place the sprinkler in service.
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 sprinklers. Higher levels of torque may
distort the sprinkler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for insufficient adjust-
ment in an Escutcheon Plate by under- or over-tight-
ening the Sprinkler. Readjust the position of the sprin-
kler fitting to suit.
Step 1.
The Sprinkler must be installed only in the pen-
dent position and with the Sprinkler waterway centerline
perpendicular to the mounting surface.
Step 2.
Install the sprinkler fitting so that the distance
from the face of the fitting to the mounting surface will be
nominally 29/32 inches (23,0 mm) as shown in Figure 1A.
Step 3.
With pipe thread sealant applied to the pipe
threads, hand tighten the Sprinkler into the sprinkler fit-
ting.
Step 4.
Wrench tighten the Sprinkler using only the
#4947 Sprinkler Socket or #4948 Wrench & Socket Com-
bination (Ref. Figure 4). The wrench recess of the
#4947 is to be applied to the sprinkler wrenching area
(Ref. Figure 1A).
Step 5.
Use the “ceiling level tolerance limit” indicator on
the Protective Cap to check for proper installation height.
Relocate the sprinkler fitting as necessary. If desired the
Protective Cap may also be used to locate the center of
the clearance hole by gently pushing the ceiling material
against the center point of the Cap.
Step 6.
After the ceiling has been completed with the 2
inch (50 mm) diameter clearance hole, use the Protective
Cap Removal Tool (Ref. Figure 5) to remove the Protec-
tive Cap and then push on the Escutcheon until its flange
just comes in contact with the ceiling. Do not continue to
push on the Escutcheon such that it lifts a ceiling panel
out of its normal position. If the Escutcheon cannot be en-
gaged with the Sprinkler, or the the Escutcheon cannot
be engaged sufficiently to contact the ceiling, relocate the
sprinkler fitting as necessary.
