5.Routine Maintenance
Your system is designed to run with the minimum of maintenance and does not normally
require much adjustment.
Weekly
Check the salt level (this may need to be done more regularly dependant on
consumption) The salt level should always be above the water level.
Check there is no sign of damage or leaks,
Check the quality of the treated water.
Monthly
Check the quality of the incoming water to see if it has changed significantly.
Yearly
Check for leaks or damage.

Soda Ash Regeneration (CR100 & CR200 Only)
GUIDELINES FOR THE USE OF SODA ASH AS A REGENERANT IN
CRYSTAL – RIGHT INSTALLATIONS
Crystal Right is a well proven iron and manganese reduction media. Provided that the guidelines are followed
with regard to the water analysis and selecting the correct grade and volume of media, then problems are rare.
However there can be certain ground conditions where dissolved gases in the raw water may lead to a reduction
in operating capacity.
During the normal service run gases present in ground water will be absorbed by the Crystal Right, and most of
these gases are released during the standard brine regeneration. However some gases [especially CO2] may
not be and stay retained in the crystals. This leads to a small reduction in Crystal-Right’s exchange capacity per
cycle which after a while can lead to a significant decrease in the exchange capacity of the unit.
To reverse the loss of capacity we have to carry out a regeneration that will release the remaining elements
retained by the crystals that have not been removed by the standard brine regenerations. The way we can
achieve this is to do regeneration with Sodium Carbonate [Na2CO3] which is also known as Soda Ash.
To reverse capacity loss we would suggest ‘shock treatment’ regeneration with Soda Ash followed by further
routine regenerations at set intervals to prevent a further build up of problem elements on the crystals. It can also
be beneficial to periodically regenerate Crystal-Right units that are working satisfactorily with Soda Ash purely as
a preventative measure; it will be beneficial to the crystals.
Soda Ash Regeneration Procedure As a Routine Maintenance
Soda Ash is a powder which needs to be dissolved in water to make a liquid that can be drawn into the unit
during a regeneration cycle, warm water will dissolve the Soda Ash faster, stirring the mixture also helps to
dissolve it. Once the measured amount has been dissolved it is added to the brine solution in the brine tank and
regeneration is initiated, during the injection cycle the mixture of brine and liquid soda ash will be drawn into the
Crystal-Right bed in the normal way. If the brine tank is fitted with a brine well you can ensure the liquid soda
ash makes direct contact with the brine by introducing it via the top of the brine well.
