This annual change-out schedule is based on a possible fuel contaminant of 2.7 mg/Sm
3
(approx.
4 ppm) of H
2
S as outlined in the standard specifications in Section 2.4. If the concentration of H
2
S in
the fuel supply exceeds the standard specification, contact GPT for the appropriate cartridge
replacement frequency.
Failure to replace the filter cartridges when required may result in excessive drop in pressure and the
possibility of contaminant carry-over to the Sentinel TEG. To order additional filter cartridges, please
contact GPT.
Do not subject the fuel filter to vapours or liquids from synthetic solvents, acetone, methanol, esters,
lacquer thinners, phosphates, etc.
Refer to APPENDIX C for SDS of fuel filter replacement cartridges prior to handling and disposal.
WARNING!
Never replace filter cartridge when the unit is under pressure. Always follow safe
work procedures when working with high pressures and ensure that pressure has
been released from the system before performing work.
