Maintenance - Pool Controls SWC Series User Manual

Maintenance

Like all equipment your chlorinator will look better and last longer if it is maintained and
operated in accordance with these instructions.
Power Supply
The Power Supply has been designed for operation in full sun and weather. However, it will
benefit from being under cover. There is little maintenance required however – some Do's
and Don'ts –
Don't:
•
Install it in a small sealed enclosure (so it does not overheat)
•
Install it in a very hot unventilated shed (so it does not overheat)
•
Allow insects to nest in the unit (because they will prevent it from functioning)
•
Install chemical drums under or close to the unit (to prevent corrosion)
•
Forget about the unit once installed – it should be checked regularly to ensure
that it is working for you
Do:
•
Install it as per the instructions
•
Check it regularly
•
Make sure the pool balance is checked regularly
The Cell
The cell does not have an unlimited life because its anodes (active electrodes) will wear
away slowly as it produces chlorine.
Scale forms on the cell cathodes (negative electrodes). Scale is a combination of
calcium/magnesium and other mineral salts (usually carbonates). The rate of scale build-
up is determined by the amount of use, the pH/calcium hardness/TA and the temperature
of the pool water. Generally concrete and plaster pools will scale much faster than
fibreglass pools due to higher calcium levels in the water caused by leaching of minerals
from the pool surface.
The cell is manufactured from extremely expensive materials so if it fails early due to lack
of maintenance, the pool operating cost will not be as economical as it could have been.
Note that bore water
water is used it is likely that faster cell scaling will be seen.
When the cell polarity is reversed any scale comes off the electrodes in crystal "sheets".
This scale is almost insoluble and can sometimes be seen as white flakes near the pool
returns. This is normal for a reverse polarity salt water chlorinator. If an automated cleaner
is used it may not be noticed at all as it is picked up.
generally contains far more minerals than scheme water. If bore
