Inspection, repair, replacement

It needs to be reviewed every six months, it needs to be maintained, and every year a full review is needed. The rack pipe, pressure hose assembly, metering clamp located in the cabinets shall be subjected to a pressure test every 5 years. The above tasks are specified in the 54/2014. (XII.5.) BM. Our colleagues draw up a report of the work done and an inspection report.
