6. INSTALLATION
WARNING: Viking sprinklers are manu-
factured and tested to meet the rigid re-
quirements of approving agencies. The
sprinklers are designed to be installed in
accordance with recognized installation
standards. Deviation from the standards or
any alteration to the sprinkler after it leaves
the factory including, but not limited to,
painting, plating, coating, or modification,
may render the sprinkler inoperative and
will automatically nullify the approval and
any guarantee made by Viking.

accordance with the latest edition of
Viking technical data, the latest stan-
dards of the National Fire Protection
Association, Factory Mutual, Loss

Prevention
Pleniere, VdS or other similar organi-
zations, and also with the provisions
of governmental codes, ordinances,
and standards, whenever applicable.
The use of dry sprinklers may be lim-
ited due to occupancy and hazard.
Refer to the AHJ prior to installation.
B. Sprinklers must be handled with care.
They must be stored in a cool, dry place in
their original container. Never install
sprinklers that have been dropped or
damaged in any way. Never install any
glass-bulb sprinkler if the bulb is cracked
or if there is a loss of liquid from the bulb. If
a glass bulb lacks the appropriate amount
of fluid, it should be set aside and returned
to Viking (or an authorized Viking distribu-
tor) for analysis as soon as possible. If the
sprinkler is not returned to Viking, it should
be destroyed. Never install sprinklers that
have been exposed to temperatures in
excess of the maximum ambient temper-
ature allowed. Such sprinklers should be
destroyed immediately.
C. Viking dry pendent sprinklers are not in-
tended for use in corrosive environ-
ments. Use only sprinklers listed for
corrosive environments when subject
to corrosive atmospheres.
WARNING: Viking dry sprinklers are to be
installed in the 1" outlet or run of malleable
or ductile iron threaded tee fittings that
meet the dimensional requirements of
ANSI B16.3 (Class 150), or cast iron
