saturate for a minimum of one half hour for filters below 16”, one hour for 18” to 30”, 2 hours
for 36” to 48” and a minimum of 3 hours for larger vessels.
After the media has been fully saturated, open the by-pass until the full backwash flow is
reached. Inspect the water going to drain for evidence of the water being milky in colour.
Once the water going to drain begins to run clear, close the by-pass and allow the unit to
settle for 5 minutes.
Open the by-pass again and inspect the water going to drain, again you will notice a milky
colour in the water.
Repeat this procedure until there is no longer any colour in the water going to drain.
At this point you may rinse the filter for 10 to 30 minutes depending on the size and then
place the valve into the service position.
Note
Check the service and backwash flow rates (see technical information). If the service
flow rates are exceeded or the backwash flow rate is not correct then the filter may not
work correctly.
If during a backwash cycle you need to skip through the cycle this can be done in the
following way. To skip to the next stage press the REGEN button.
3.3 Service
Water flows into the valve at the top, down through the media and then up through the ‘riser’
tube in the middle of the vessel. As the water travels through the media the contaminants are
removed. The timer options are set to automatically self clean (backwash) and wash away any
of the accumulated contaminants.
4.Routine Maintenance
The filter system is designed to run with the minimum of maintenance and does not normally
require much adjustment.
Monthly
Check there is no sign of damage or leaks, check drain lines and power cables are still
in good condition and not kinked.
Yearly
We recommend that a competent service engineer checks the system annually. The
inlet and outlet pipes need to be rinsed, the drain line checked for degradation, and the
system flushed through. The media should be checked, if pH it probably needs to be
topped up.
The quality of the treated water needs to be checked regularly. How regularly depends on
what the water is being used for eg drinking water or irrigation etc. If the water is being used
for drinking water then it needs to be checked more regularly and the relevant Private Water
regulations covers the sampling and testing routines for England this is “The Private Water
Supplies Regulations 2009” No. 3101. However it is sensible to at least partially test the
treated water every 3 months or so and certainly every 6 months to look for compliance. A
competent water treatment company can help with this.
