Installation
The Central Model BVR-2 Residential Pendent Sprinklers
must be installed in accordance with the following instruc-
tions:
NOTES
Do not install any bulb type sprinkler if the bulb is cracked
or there is a loss of liquid from the bulb. With the sprinkler
held horizontally, a small air bubble with an approximate
diameter of 1/16 inch should be present.
A leak tight 1/2 inch NPT sprinkler joint should be obtained
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 1/2
inch NPT sprinklers. Higher levels of torque may distort the
sprinkler inlet with consequent leakage or impairment of the
sprinkler.
Step 1. The sprinkler must only be installed in the pendent
position and with the deflector parallel to the mounting
surface.
Step 2. After installing the BV Res./QR Recessed Support
Cup (or other acceptable escutcheon, as applicable) over
the sprinkler pipe threads and with pipe thread sealant
applied to the pipe threads, hand tighten the sprinkler into
the sprinkler fitting.
Step 3. Wrench tighten the sprinkler using only a BV
Sprinkler Wrench (1099 - Ref. Figure 3). The wrench recess
of the BV Sprinkler Wrench is to be applied to the sprinkler
wrench flats (Ref Figure 1).
Step 4. For Recessed Pendent Sprinkler Applications, a
Protective Cap is available which helps to prevent damage
to the sprinkler during ceiling installation and/or during
application of the finish coating of the ceiling. Place the
Protective Cap over the Recessed Support Cup and push it
upwards until it bottoms out against the sprinkler deflector.
NOTE
As long as the Protective Cap remains in place, the system
is considered to be "Out of Service"
Step 5. After the ceiling has been completed, remove and
discard the Protective Cap. If the Sprinkler has been
damaged, replace the entire Sprinkler assembly. Do not
attempt to modify or repair a damaged sprinkler.
Step 6. Push the outer ring of the Recessed Escutcheon
over the Recessed Support Cup. Do not continue to push
on the Recessed Escutcheon such that it lifts a ceiling
panel out of its normal position. If the Recessed Escutch-
eon cannot be engaged with the Support Cup or the
Recessed Escutcheon cannot be engaged sufficiently to
contact the ceiling, the Sprinkler Fitting must be reposi-
tioned.
