6. Maintenance
6.1
Dirt trap
Dirt traps must be cleaned periodically, initially at short intervals.
When opening the dirt trap please pay attention to points 2.3. When putting back into operation watch points 4.1...4.4 of these
instructions.
6.2
Meter, spare parts
Check connections periodically for tightness and if necessary tighten again. For control and cleaning, the measuring chamber and the
ring piston of the meters DN15 ... 50 can be removed without demounting the meter off the pipe.
The cleaning and revision cycle depends largely on the conditions of operation. Under favourable conditions 5 ... 10 years are suffi-
cient. Check the units for corrosion. When ancillary equipment is used, observe their mounting and operation instructions.
Spare part-lists may be requested from Aquametro.
