	What to do:	Interval:	Part kit:
Procedure 1	Check the negative pressure with u-tube manometer or digital manometer. Adjust if necessary! Setting level is 60,00 mmH2O! Replace the sintered bronze air filter/fresh air filter in the measuring head. Clean the fresh air bores in the measuring head. Use the cleaning needle (Part no.: 151482 – cleaning kit). Clean both infrared sensor glasses in the measuring head with cotton pins and technical alcohol.	Every month or 650 running hours. (Whatever comes first)	Maintenance kit – Part no.:151481 Cleaning kit – Part no.: 151482 U-tube gauge kit – Part no.: 270532 Test glass kit – Part no.: 11072-270453
Procedure 2	Replace filter in pressure regulator. If you have a water separator: Replace filter cartridge of water separator (Part no.: 273119).	Every 4 months or 2600 running hours. (Whatever comes first)
Procedure 3	Replace complete service kit on OMD. Clean the inside & outside of base plate. Check performance of pressure regulator- replace parts if necessary!

Procedure 4	Replace measuring head. Use our Exchange Pool Service (ExP) for this procedure! NOTE: When ordering an exchange unit – always inform us about engine type! Replace complete service kit on OMD. Clean the inside & outside of base plate. Check performance of pressure regulator- replace parts if necessary! Clean suction pipes/ pipe system and siphon blocks with compressed air! Check sampling funnels/pipe system. If your system has siphon blocks: Replace rubber inserts and o-rings in siphon blocks (Part no.: 10095/360106 & 365287).
