7. INSTALLATION
WARNING: Viking sprinklers are manu-
factured and tested to meet the rigid
requirements of the approving agency.
The sprinklers are designed to be in-
stalled in accordance with recognized
installation standards. Deviation from
the standards or any alteration to the
sprinkler after it leaves the factory in-
cluding, but not limited to, painting, plat-
ing, coating or modification, may render
the sprinkler inoperative and will auto-
matically nullify the approval and any
guarantee made by The Viking Corpora-
tion.
A. Sprinklers are to be installed in ac-
cordance with the latest published
standards of the National Fire Protec-
tion Association, Factory Mutual,
Loss Prevention Council, Assemblee
Pleniere, Verband der Sachver-
sicherer or other similar organiza-
tions and also with the provisions of
governmental codes, ordinances and
standards whenever applicable. For
conditions not specifically covered by
the Standards, refer to the "Viking
Residential Installation Guide". Fi-
nal approval and acceptance of all
Residential Sprinkler Installations
must be obtained from the Author-
ity Having Jurisdiction. Residen-
tial sprinklers are generally consid-

ered special service sprinklers for
one and two family dwellings, mobile
homes and residential portions of
other occupancies where allowed.
The use of residential sprinklers may
be limited due to occupancy and haz-
ard. The minimum flow rate indicated
must be provided at the sprinkler,
therefore, the system piping must be
hydraulically calculated. Refer to the
Authority Having Jurisdiction prior to
installation.
B. Sprinklers must be handled with care.

Horizon
Model H-3 Residential
Flush sprinklers are provided with a
plastic protective shell which should
remain in place over the sprinkler
body during installation, testing, and
any time the sprinkler is handled or
shipped. The plastic protective shell
must be removed prior to placing the
system in service. See paragraph
"F" below. Prior to installation, sprin-
klers must be stored in a cool, dry
place in their original shipping con-
tainer. Never install sprinklers that
have been dropped, damaged in any
way, or have been exposed to tem-
peratures in excess of maximum am-
bient temperature allowed. Such
sprinklers should be destroyed im-
mediately.
C. Corrosion resistant sprinklers must
be installed when subject to corrosive
atmospheres. Viking Horizon
klers are not intended for use in cor-
rosive environments.
D. Use care when locating sprinklers
near fixtures that can generate heat.
Do not install sprinklers where they
will be exposed to temperatures that
exceed the maximum recommended
ambient temperature for the tem-
perature rating used.
E. Sprinklers must be protected from
mechanical damage. Wet pipe sys-
tems must be provided with adequate
heat.
F. The sprinklers must be installed after
the piping is in place to prevent me-
chanical damage. Before installing,
make sure the appropriate model,
style, orifice size, and temperature
rating with the desired response
characteristic is used. Install the
sprinklers according to the following
steps:
Step 1: Install all piping and cut the
sprinkler drop nipple to position
the 1/2" (15mm) NPT outlet of the
reducing coupling at the desired
