Maintenance
Prevent bacteria from growing in the pore fluid. Do this by adding a bactericide
to the fluid and by changing the pore fluid frequently.
Pore fluid lines can be flushed with a mild detergent solution. Use the steps in
“Purging and Filling the Fluid Lines” on page 16 to flush the lines. Follow the
detergent flush with a thorough fresh water flush.
Check the accumulators’ precharge pressures at least once a month. Your Series
111 Accumulator manual has details on accumulator maintenance.
