(3) Air intake for the turbocharger
(4) Flame arrestor for the intake air
(5) Flame arrestor for the aftercooler condensate drain valve
(6) Aftercooler condensate drain valve The C15 Hazardous Location SCAC (separate circuit aftercooled) Diesel Engine is equipped with a flameproof intake system. The system has been type tested and approved to the following standards:
EN 1834-1 for Gas Group IIA
Temperature Class T3 with an ambient capability of 50° C (122° F)The flameproof system includes the following components:
An intake air flame arrestor mounted on the inlet of the turbocharger
A flame arrestor on the aftercooler condensate drain valveThe flameproof intake system is designed with tight seals, closely matched joints, and robust enclosures to prevent any internal flames or explosions from propagating to the exterior atmosphere.Note: Inspect the flame arrestor for the aftercooler and clean the flame arrestor if necessary at the following interval:
Table 1
Maintenance Intervals for Inspecting and Cleaning(1) of the Flame Arrestors
Flame Arrestor for the Turbocharger Air Inlet System PM Level 1 - Every 12750 (3375 US gal) of Fuel or 250 Service Hours or 6 Months
Flame Arrestor for the Aftercooler Condensate Drain Valve Every 50 Service Hours

When replacement parts are required for this product, Caterpillar recommends using Cat replacement parts or parts with equivalent specifications including, but not limited to, physical dimensions, type, strength, and material.Never reuse any clamps, seals, or gaskets in the flameproof intake or exhaust system. Always replace clamps, seals, and gaskets with new Cat parts which match the parts being replaced by the exact Cat part number.Failure to heed this warning may lead to premature failures, product damage, personal injury, or death.

(7) Bolts
(8) O-ring seal Residue from normal engine operation may begin to plug the engine intake flame arrestor.
Remove the bolts that attach the flame arrestor to the inlet air line.
Remove and dispose of the seal.
Remove the flame arrestor and hold the flame arrestor up to a light to ensure that the passages are clear. If necessary, clean the flame arrestor with isopropyl alcohol or suitable solvent. Use filtered dry air with a maximum pressure of 30 psi to remove the solvent and dry the flame arrestor. Do not clean by inserting probes as the fine passages may be enlarged which impairs the performance of the flame arrestor.
Always replace the O-ring seal with a new Cat O-ring seal with the same part number. Replace the seal.
