6.5 Super-Chlorinating
From time to time, your pool 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 the Chlorine doing its job of killing bacteria and algae.
Chloramines are actually 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
easyCHEM 770
does all the hard work for you by adding the amount of Chlorine that is needed.
You do not need to handle the Chlorine at all !
To Super-chlorinate your pool…
1. Plug
the
easyCHEM 770
mains lead into the mains power outlet to switch the controller on.
2. Press .
3. Press until “
→
SuperChlorine
” is selected and press
.
4. The Super-chlorination menu is now displayed, for example…
Chlorine Litres
0L
↑↓
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.
5. The
easyCHEM 770
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 0.1/10L
Enter Stops
To stop adding the Chlorine immediately, press
.
6. When
the
easyCHEM 770
has finished adding the Chlorine or if the user stopped the dosing
prematurely, the
easyCHEM 770
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.
7. Normal operation of the
easyCHEM 770
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
easyCHEM 770
will not add any acid until the ORP reading has returned to normal.
