3. PRODUCT DESCRIPTION
Viking Micromatic®Special Response
Sprinklers are small thermosensitive
glass bulb sprinklers available in various
finishes, temperature ratings, and orifice
sizes to meet design requirements.
During fire conditions, the heat-sensitive
liquid in the glass bulb expands, causing
the bulb to shatter, releasing the pip cap
and sealing spring assembly. Water
flowing through the sprinkler orifice
strikes the sprinkler deflector forming a
uniform spray pattern to extinguish or
control the fire.

5. 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 lim-
ited to: painting, plating, coating, or
modification, may render the sprinkler
inoperative and would automatically nul-
lify the approval and any guarantee
made by The Viking Corporation.
A. Viking sprinklers are to be installed
in accordance with the latest
edition of Viking technical data,
the latest standards of NFPA, FM
Global, LPCB, Assemblee
Pleniere, VdS, or other similar or-
ganizations, and also with the pro-
visions of governmental codes,
ordinances, and standards when-
ever applicable. The use of Special
Response sprinklers may be limited
due to occupancy and hazard. Refer
to the Authority Having Jurisdiction
prior to installation.
B. Sprinklers must be handled with care.
They must be stored in a cool, dry
place in their original shipping con-
tainer. Never install sprinklers that
have been dropped, damaged, or ex-
posed to temperatures exceeding

the maximum ambient temperature
allowed (refer to Table 1). Never in-
stall any glass-bulb sprinkler if the
bulb is cracked or if there is a loss of
liquid from the bulb. Any sprinkler
with a loss of liquid from the glass
bulb should be destroyed immedi-
ately.
C. Sprinklers must be protected from
mechanical damage. Sprinklers sub-
ject to mechanical damage must be
protected with an approved sprinkler
guard.
D. Use only sprinklers listed as corro-
sion resistant when subject to corro-
sive environments. When installing
corrosion-resistant sprinklers, take
care not to damage the corrosion-re-
sistant coating. Use only the special
wrench designed for installing coated
and recessed Viking sprinklers (any
other wrench may damage the unit).
E. Use care when locating sprinklers
near fixtures that can generate heat.
Do not install sprinklers where they
could be exposed to temperatures
exceeding the maximum recom-
mended ambient temperature for the
temperature rating used.
F. Wet-pipe systems must be provided
with adequate heat. Sprinklers sup-
plied from dry systems in areas sub-
ject to freezing must be listed dry
sprinklers, or upright or horizontal
sidewall sprinklers installed so that
water is not trapped. For dry sys-
tems, pendent sprinklers and side-
wall sprinklers installed on return
bends are permitted, where the
sprinklers, return bend, and branch
line piping are in an area maintained
at or above 40 °F (4 °C). When in-
stalling Special Response Sprin-
klers on dry systems, refer to the in-
stallation standards and the Authority
Having Jurisdiction.
G. Before installation, be sure to have
the appropriate sprinkler model and
style, with the correct orifice size,
temperature rating, and response
characteristics. The sprinklers must
be installed after the piping is in place
to prevent mechanical damage.
Keep sprinklers with protective caps
or shields contained within the caps
or shields during installation and test-
ing, and any time the sprinkler is
shipped or handled.

2. Apply a small amount of pipe-joint
compound or tape to the external
threads of the sprinkler only, tak-
ing care not to allow a buildup of
compound in the sprinkler inlet.
NOTE: Sprinklers with protective
caps or bulb shields must be con-
tained within the caps or shields
before applying pipe-joint com-
pound or tape.
3. Install the sprinkler onto the piping
using the special sprinkler wrench
only, taking care not to over-
tighten or damage the sprinkler
operating parts. DO NOT use the
deflector to start or thread the
sprinkler into a fitting.
H. After installation, the entire sprinkler
system must be tested. The test must
be conducted to comply with the in-
stallation standards.
Make sure the sprinkler has been
properly tightened. If a thread leak
occurs, normally the sprinkler must
be removed, new pipe-joint com-
pound or tape applied, and then rein-
stalled. This is due to the fact that
when the joint seal is damaged, the
sealing compound or tape is washed
out of the joint.
Air testing the sprinkler piping prior to
testing with water may be considered
in areas where leakage during testing
must be prevented. Refer to the in-
stallation standards and the Authority
Having Jurisdiction.
I. Remove plastic protective sprinkler
caps or shields AFTER the ceiling
finish work is completed where
the sprinkler is installed and there
no longer is a potential for me-
chanical damage to sprinkler op-
erating elements. To remove the
bulb shields, simply pull the ends of
the shields apart where they are
snapped together. To remove caps
from frame style sprinklers, turn the
caps slightly and pull them off the
sprinklers. SPRINKLER CAPS OR
BULB SHIELDS MUST BE RE-
MOVED FROM SPRINKLERS BE-
FORE PLACING THE SYSTEM IN
SERVICE! Retain a protective cap in
the spare sprinkler cabinet.
J. If it is necessary to remove the entire
sprinkler unit, the system must be
taken out of service. See section 7.
MAINTENANCE and follow all warn-
ings and instructions.
7. MAINTENANCE
NOTICE: The owner is responsible for
maintaining the fire protection system
and devices in proper operating condi-
tion. For minimum maintenance and in-
spection requirements, refer to the
NFPA standard that describes care and
maintenance of sprinkler systems. In
addition, the Authority Having Jurisdic-
tion may have additional maintenance,
testing, and inspection requirements
that must be followed.
A. Sprinklers must be inspected on a
regular basis for corrosion, mechani-
cal damage, obstructions, paint, etc.
The frequency of the inspections
may vary due to corrosive atmo-
spheres, water supplies, and activity
around the device.
B. Sprinklers that have been painted,
caulked, or mechanically damaged
must be replaced immediately.
Sprinklers showing signs of corrosion
shall be tested and/or replaced im-
mediately as required. Installation
standards require sprinklers to be
tested, and if necessary, replaced af-
ter a specified term of service. Refer
to the installation standards (e.g.,
NFPA 25) and the Authority Having
Jurisdiction for the specified period of
time after which testing and/or re-
placement is required. Sprinklers
that have operated cannot be reas-
sembled or re-used, but must be re-
placed. When replacing sprinklers,
use only new sprinklers.
C. The sprinkler discharge pattern is crit-
ical for proper fire protection. Nothing
should be hung from, attached to, or
otherwise obstruct the discharge pat-
tern. All obstructions must be imme-
diately removed or, if necessary, ad-
ditional sprinklers installed.
D. When replacing existing sprinklers,
the system must be removed from
service. Refer to the appropriate sys-

tem description and/or valve instruc-
tions. Prior to removing the system
from service, notify all Authorities
Having Jurisdiction. Consideration
should be given to employment of a
fire patrol in the affected area.
1. Remove the system from service,
drain all water, and relieve all
pressure on the piping.
2. Using the special sprinkler wrench,
remove the old sprinkler and in-
stall the new unit. Care must be
taken to ensure that the replace-
ment sprinkler is the proper model
and style, with the correct orifice
size, temperature rating, and re-
sponse characteristics. A fully
stocked spare sprinkler cabinet
should be provided for this pur-
pose. Follow instructions in sec-
tion 6. INSTALLATION.
3. Place the system back in service
and secure all valves. Check for
and repair all leaks. Sprinkler sys-
tems that have been subjected to
a fire must be returned to service
as soon as possible. The entire
system must be inspected for
damage and repaired or replaced
as necessary. Sprinklers that
have been exposed to corrosive
products of combustion or high
ambient temperatures, but have
not operated, should be replaced.
Refer to the Authority Having Ju-
risdiction for minimum replace-
ment requirements.
