The Model BV/BV-QR Intermediate Level Automatic Sprinklers
must be installed in accordance with the following instructions.
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

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.
Upright Sprinklers
Step 1. Upright sprinklers must be installed only in the upright
position. The deflector is to be parallel to the ceiling, roof, or
mounting surface, as applicable.
Step 2. With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the sprinkler fitting using only
the Combination Wrench (Ref. Fig. 5). The Combination
Wrench is to be applied to the wrench flats only.
Pendent Sprinklers
Step 1. Pendent sprinklers must be installed only in the
pendent position. The deflector is to be parallel to the ceiling,
roof, or mounting surface, as applicable.
Step 2. With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.

pendent position. The deflector is to be parallel to the ceiling,
roof, or mounting surface, as applicable.
Step 2. Thread the WS-3 Water Shield onto the sprinkler
threads with the stamped marking toward the deflector and
just to the end of the threads. There should be an 1/8 inch (3,2
mm) gap between the plate and the Sprinkler Wrench Flat.
Step 3. With pipe thread sealant applied to the pipe threads,
hand tighten the sprinkler into the sprinkler fitting.
Step 4. Tighten the sprinkler into the sprinkler fitting using only
the Combination Wrench (Ref. Fig. 5). The Combination
Wrench is to be applied to the wrench flats only.
Step 5. Rotate the WS-3 Water Shield clockwise (looking up)
so that it engages with the sprinkler threads.
