Description
Reliable Model TNL280 is a cULus listed pendent open spray nozzle for use in fixed fire protection systems. The nozzle has an Electroless Nickel PTFE (ENT) finish and it is cULus listed as corrosion resistant. Verify compatibility with the environment where the nozzle will be located prior to installation.
Installation
Model TNL280 nozzles must be handled carefully. Nozzles should be stored in the original packaging until installed. Handle nozzles only by the frame and not by the deflector. Nozzles that are visibly damaged should not be installed.
Install the nozzle by applying PTFE-based thread sealant to the male threads of the nozzle. Thread the nozzle into the sprinkler system fitting by hand, then tighten the nozzle using only the Reliable Model N1 wrench. Recommended installation torque is 30 to 40 N/m. Do not exceed the maximum recommended torque. Exceeding the maximum torque may damage and impair the performance of the nozzle.
