Recommendation:

Use Authorized Service Personnel (ASP) for this procedure.

  • Authorized service personnel will perform an inspection of complete OMD installation. Condition of measuring head to be checked and replaced if necessary!

If not possible to use ASP, alternatively do as follows:

  • Replace exchange unit set and clean all necessary parts. Replace filter and check pressure regulator performance, replace unit if necessary. Clean suction pipes/pipe system and siphon blocks with compressed air and fill siphon blocks with oil! Check all sampling funnels positions and make sure they are firmly attached. Tighten all connections and make final functional test with smoke ampulla kit through sampling funnels to ensure there are no blockage in the pipe system.

If ASP is not possible, contact us for exchange unit set at: epp@epp.no or phone: +47 92 46 32 20!

Every 48 months or 32 000 engine running hours – whatever comes first!
