3.7 Super-Chlorinating
From time to time, your pool service professional may ask you to super-chlorinate your pool. This
is necessary when the level of Chloramines becomes too high. Chloramines are the undesirable
compounds that form as a result of Chlorine killing bacteria and algae. Chloramines are the
compounds that cause the “Chlorine” smell and itchy eyes and skin. They will form in all pools,
including those using salt chlorinators. Super-Chlorinating oxidises these Chloramines back to
useful Chlorine.
Super-chlorinating is simply the process of adding a large amount of Chlorine in one dose. Your
pool professional will let you know how much Chlorine is required for your size pool. The
Chemflo
does the work for you by adding the amount of Chlorine that is needed. You do not need to handle
the Chlorine.
To Super-chlorinate your pool…
1. Press .
2. Press until “
o
SuperChlorine
” is selected and press
.
3. The Super-chlorination menu is now displayed, for example…
Chlorine Litres
0.0L
np
Enter
Press
and
to enter the number of Litres of Chlorine that you wish to add to the pool
and press
. The maximum dose that can be added is 25 Litres.
4. The
Chemflo
now proceeds to add the Chlorine. The display shows how much has been
added so far and how much will be added in total, for example…
Chlorine 0.0L
Enter Stops 0.7L
To stop adding the Chlorine immediately, press
.
5. When the
Chemflo
has finished adding the Chlorine or if the user stopped the dosing
prematurely, the
Chemflo
will continue to operate the main pool pump for a further 4 hours.
This will ensure that the Chlorine that was added will be thoroughly mixed. No ORP or pH
monitoring or chemical addition will occur during the 4 hours.
Running 00:00
pump for 4 hours
The time on the top right hand side of the display will count up to the 4 hours so that you know
how long it has been operating.
Press
to stop the 4 hour pumping cycle immediately. Note that the Chlorine may not have
mixed properly if pumping is stopped early.
Normal operation of the
Chemflo
will now resume. It is normal for the pH reading to be quite
high due to the large dose of Chlorine that was just added. This will return to normal within a
few days, when the Chlorine is back to normal levels. To avoid unnecessary chemical usage,
the
Chemflo
will not add any acid until the ORP reading has returned to normal.
