3. PRODUCT DESCRIPTION
®
The Viking Microfast Model M-6, Low-
Flow Residential Pendent Sprinkler, is a
small, high sensitivity, glass-bulb resi-
dential spray sprinkler. The sprinkler is
available in several finishes, with tem-
perature ratings to meet varying design
requirements. The orifice design, with a
K Factor of 3.1, allows efficient use of
available water supplies for the hydrau-
lically designed fire protection system.
The small rugged 3mm glass bulb, and
special deflector combine speed of op-
eration and area of coverage to meet
residential sprinkler standards, while
providing a pleasing aesthetic appear-
ance. The sprinkler is listed for use be-
low smooth, flat horizontal ceilings only.
During fire conditions, the heat sensitive
liquid in the glass bulb expands, causing
the glass to shatter, releasing the pip cap
and sealing spring assembly. The water
flowing through the sprinkler orifice
strikes the sprinkler deflector forming a
uniform spray pattern to extinguish or
control the fire.

LOW-FLOW RESIDENTIAL
PENDENT SPRINKLER
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 provisions of gov-
ernmental 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 special service
sprinklers for use in one and two fam-
ily dwellings, mobile homes, and resi-
dential portions of other occupancies
where allowed. The use of Residen-
tial Pendent sprinklers may be lim-
ited due to occupancy and hazard.
The minimum flow rate indicated for a
listed area of coverage must be pro-
vided at the sprinkler, therefore, the
system must be hydraulically calcu-
lated. 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 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.
Never install sprinklers which have
been exposed to temperatures in ex-
cess of maximum ambient tempera-
ture allowed. Such sprinklers should
be destroyed immediately.
C. Corrosion resistant sprinklers must
be installed when subject to corrosive
atmospheres. Viking Microfast
Residential Pendent Sprinklers are
not intended for use in corrosive en-
vironments.
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
