Brown Waxy <br /> Footnotes <br /> The sprinkler temperature rating is stamped on the deflector. <br /> 2 Based on NFPA-13.Other limits may apply,depending on fire loading,sprinkler location,and other requirements of the Authority Having Jurisdiction. <br /> Refer to specific installation standards. <br /> 3 Sprinklers of Ultra-High temperature rating are intended for use inside ovens,dryers,or similar enclosures with normal operating temperatures above <br /> 300 OF(149°C).Where the ambient temperature around the Ultra-High temperature rated sprinkler is significantly reduced below 300 OF(149 °C), <br /> response time may be severely retarded. <br /> 4 The corrosion-resistant coatings have passed the standard corrosion test required by the approving agencies indicated in the Approval Charts.These <br /> tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coatings are com- <br /> patible with or suitable for the proposed environment. For automatic sprinklers,the coatings indicated are applied to the exposed exterior surfaces <br /> only. Note that the spring is exposed on sprinklers with Polyester and ENT coatings. For ENT coated automatic sprinklers,the waterway is coated. <br /> 5 Wax melting point is 170 OF(76°C)for 286 OF(141 °C)temperature rated sprinklers. <br /> Protective Sprinkler Wrench Flat <br /> Clip ` Hn <br /> Protective Sprinkler <br /> Cap <br /> Figure 1: Standard Sprinkler Wrench 10896W/B <br /> Form No. F_031414 19.02.21 Rev 19.1 <br />
