Viron e-Quilibirum Series Chlorinator Instructions V07-20
23
CyA bonds to chlorine more effectively in sunlight hours. Therefore, ORP readings will be lower in sunlight hours
than at night. As the chlorine bonds with CyA during sunlight hours, the ORP may drop more than 100 mv. This
means the e-Q chlorinator will drive higher levels of chlorine during sunlight hours as the chlorine is temporarily
bonded with CyA. After sunset, the CyA bond with chlorine will reduce, freeing up the chlorine to oxidize with
bacteria and exhibiting an increased oxidization potential reading on the e-Q chlorinator.
Why use CyA at all? CyA is used to extend the life of chlorine when the chlorine is manually added in the form of
a tablet, granules or liquid and it is not monitored by a measuring device. This reduces the quantity and cost of
chlorine used and maintains a residual chlorine in the pool even though manual dosing may take place every 2 or
3 days.
The AstralPool e-
Q Chlorinator continually monitors and produces chlorine to suit the pool’s chlorine demand and
costs very little to convert your pool minerals into chlorine.
AstralPool do not recommend the use of CyA in
conjunction with a Salt Chlorinator that is suitably sized and incorporates a chlorine (ORP) sensing device
to produce chlorine.
This includes adding CyA to the pool or supplementing the chlorinator with Dichlor or
Trichlor, both of which have CyA as an active constituent.
In particular, CyA should not be used in a covered
pool, indoor pool or a spa pool.
