3. PRODUCT DESCRIPTION
Viking Microfast and MicrofastHP Quick Response Upright and Conventional (Old Style) Sprinklers
are small thermosensitive glass bulb spray sprinklers available in various finishes, temperature ratings,
and orifice sizes to meet design requirements. The special Poly finishes and Teflon coatings can be used
in decorative applications where colors are desired. In addition, these finishes have been investigated for in-
stallation in corrosive atmospheres and are cULus listed as corrosion resistant as indicated in the Approval
Chart. (Note: FM Global has no approval classification for Teflon and Poly finishes as corrosion resistant.)
The pip cap and sealing assembly of the sprinkler are held in place by the glass bulb operating element. During fire con-
ditions, 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.

1 The sprinkler temperature rating is stamped on the deflector.
2 Based on NFPA -13. Other limits may apply, depending on fire loading, sprinkler location, and other requirements of the Authority Having
Jurisdiction. Refer to specific installation standards.
3 The corrosion- resistant coatings have passed the standard corrosion test required by the approving agencies indicated on page 51 c. These
tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end -user that the coatings
are compatible with or suitable for the proposed environment. For automatic sprinklers, the coatings indicated are applied to the exposed
exterior surfaces only. Note that the spring is exposed on sprinklers with Poly finishes and Teflon coatings.

5. ORDERING INSTRUCTIONS (Also refer to the current Viking price list.)
Order Microfast Quick Response Upright and Conventional Sprinklers by first adding the appropriate suffix for the sprinkler
finish and then the appropriate suffix for the temperature rating to sprinkler base part number.
Poly Finish Suffix: Brass = A, Chrome- Enloy F.
White Poi Finish = M -/W, Black Poly Finish = M - /B, and Black Teflon = N
Temperature Suffix ( °F / °C): 135 °168 = A, 155 ° /68 = B, 175 °179 = D, 200 ° /93 = E, and 286°/141 = G
For example, Sprinkler VK300 with a 1/2" thread, Brass finish and a 155 °F/68 °C temperature rating = Part No. 06661 BAB.
