OR 52-7
According to the IMO Resolution MEPC 07 (49), section 4.2., the measuring accuracy of the 5 ppm
bilge alarm must be checked when the equipment is inspected in order to obtain the extension of the
period of validity of the IOPP certificate (5 years) as specified by the manufacturer.
For this inspection the measuring transducer ORG 2 must be exchanged.
Please order a replacement for the measuring transducer ORG 2 (stock code 389 427), indicating the
serial number, in good time before the IOPP certificate expires.
Before exchanging the measuring transducer undo the central screw of the connectors for the light
emitter/receiver and for the purging valve and detach the connectors.
Remove the measuring transducer and mount the replacement equipment.
Attach the connectors to the light emitter/receiver and the purging valve and tighten the central screw.
