“What is the expected life span of the RO Membranes
and what maintenance should I carry out?”
Two to three years. The life of this unit will depend on how regularly you change the pre-filters and flush the membrane. We recommend that you flush the membrane by turning the flush valve at least once a month and leave running for at least ten minutes.
Pre-filter changing is the single most important thing you can do to prolong the life of your reverse osmosis membrane. Failure to change these pre-filters, whilst not immediately affecting water quality, will gradually start to damage the membrane. Recommend change intervals are:
For single operator usage - four months
For dual operator usage - two-three months
Always change all three pre-filters together. After replacing filters, disconnect final filter output from membrane housing and allow unit to run for at least one hour. This will enable any damaging particles from new filters to flush through. Reconnect and start processing again.
Resin bead change is the final stage in the unit and this will need changing whenever your output TDS reading rises above 000-001ppm. To change resin bead, simply unscrew end of canister, pull out mesh or foam packer (keep), empty and throw away old resin, tightly pack in new resin, replace mesh or foam packer and re-fit end cap.
