Installation
The Model H
17
⁄
32
Sidewall and
Recessed Sidewall Sprinkler must be
installed according to current NFPA
13 Standards. Deviations from these
requirements and standards or any
alteration to the sprinkler itself will
void any warranty made by Central
Sprinkler Company. In addition,
installation must also meet local
government provisions, codes and
standards as applicable.
The system piping must be
properly sized to ensure the minimum
required flow rate at the sprinkler.
Check for the proper model, style,
orifice size and temperature rating
prior to installation. Install sprinklers
after the piping is in place to avoid
mechanical damage. Replace any
damaged units. Wet pipe systems
must be protected from freezing; refer
to the Central Bulletins on the Model
H-1 Dry Horizontal Sidewall
Sprinklers for use in dry pipe sprinkler
installations.
Upon completion of the installation,
the system must be tested per
recognized standards.
In the event of a thread leak,
remove the unit, apply new pipe joint
compound or tape and reinstall.
CAUTION: Do not wrench or turn
the deflector, as this action may
damage the sprinkler and cause it
to leak under pressure.
Special care must be taken when
installing sprinklers with a CPVC
system. Sprinklers must be installed
after the CPVC manufacturer's
recommended setting time for the
primer and cement to ensure that
neither accumulates within the
sprinkler.
Special care must be taken when
installing with a copper system.
Sprinklers must be installed only after
the inside of the sprinkler nipple and
associated fittings have been wire
brushed to remove any flux. Residual
flux can cause corrosion and in
extreme cases can impair proper
sprinkler operation.
Installation Sequence
Step 1. The unit must be installed in
the horizontal position.
Step 2. Use only a non-hardening
pipe joint compound or Teflon* tape.
Apply only to the male threads.
Step 3. Hand tighten the sprinkler
into the fitting. Then use a Central
Sprinkler H & HF wrench to tighten
the unit into the fitting. A leak-tight
joint requires only 7-14 ft-lbs
(9.5 - 19.0
Nm)
. of torque; a tangential force of 14-
28 lbs
(62.3 - 124.5 N)
. delivered through a
6"
(150 mm)
handle will deliver adequate
torque. Torque levels over 21 ft-lbs
(28.6 Nm)
may distort the orifice seal,
resulting in leakage.
Sprinklers must be handled
carefully. They must not be
transported or stored where ambient
temperatures may exceed 100
o
F/

C. For best results, store them in
a dry, cool location in the original

Sidewall and Recessed Sidewall Sprinklers are U.L. Listed for Extended Coverage applications in
light hazard occupancies only. For non-recessed versions, the distance away from the wall is per NFPA 13.
