Operation and maintenance, Discfilter HPF2200-series PFLC
4.4 Equipotential bonding
The Hydrotech Discfilter and associated equipment should be protected with a suitable system
for equipotential bonding. This is very important to prevent galvanic corrosion. Ideally use a ca-
ble with a cross section of 10–16 mm2. The cable should be connected to the same electrical
potential as the drive system.
4.5 Checking drum rotation
Start drum rotation and check that the drum rotates in the same direction as the rotation arrow
on the drive unit cover.
4.6 Pipe connections
Piping for reject should have a minimum inclination of 1%.
