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
Ju
risdiction. Refer to specific installation standards.
3
Sprinklers of Ultra-High temperature rating are intended for use inside ovens, dryers, or similar enclosures with normal oper-
ating temperatures above 300 °F (149 °C). Where the ambient temperature around the Ultra-High temperature rated sprinkler
is significantly reduced below 300 °F (149 °C), response time may be severely retarded.
4
The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated
on pages 11 d-e. 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
Polyester and Teflon
®
coatings. For Teflon
®
coated open sprinklers only, the waterway is coated.

Wax Over Polyester is unavailable for Sprinklers VK023 and VK122.

Wax melting point is 170 °F (76 °C) for 212 °F (100 °C) and 286 °F (141 °C) temperature rated sprinklers.
