If the salt level drops to a very low level, ALL the
-
GREEN LED indicators
-
on the readout will
not illuminate until eventually only the first three
AMBER
lights will illuminate. (Indicating to
check the salt level) The illumination of
AMBER
lights also indicates that low levels of chlorine
are being produced and that more salt may need to be added to increase the salt level in the pool
so that the WATERMAID Chlorinator can produce more chlorine, enough so that the pool
remains clean, clear, sparkling and sterile.
PLEASE NOTE:
The WATERMAID QT400 Cell only requires a salt level of 4000 PPM to achieve a reading of
100% on the front control panel. This is ideal for pool owners that wish to run with a lower salt
level. An even lower level may only be needed for pools that are heated.
The figures given in the table above, assume a water temperature in the pool of 20 Deg. C / 68
Deg. F.

WATER TEMPERATURE --
Water temperature is also a determining factor in the amount of
chlorine production that the cell produces, again proportional to the LED readout on the front
panel of the WATERMAID Power Pack.
WARMER
WATER TEMPERATURES result in the water being
more
conductive and the cell
producing
more
chlorine.
COOLER
WATER TEMPERATURES result in the water being
less
conductive and the cell
producing
less
chlorine.
PLEASE NOTE:
Swimming Pool & Spa Owners that use HEATERS to warm the water can maintain a lower salt
level in the swimming pool and still achieve a 100% reading on the LED Control panel.
5.
CALCIFICATION ON THE CELL --
The build-up of calcium deposits on the centre cell
electrode can also determine the chlorine production from the cell.
THICK
heavy build-up can result in less chlorine being produced.
VERY HARD, THIN
calcium deposits can also reduce the chlorine production from the cell.
PLEASENOTE:
Usually a small build up of calcium will not result in a loss of chlorine production from the unit.
Is advised to inspect the cell every 2 - 4 weeks and check the build up on the cell.
If necessary, clean the cell as per the instructions.
In some cases, a thick calcium build-up may cause the reading on the LED % readout to read
normally however result in low levels of chlorine being produced by the cell. It is important that
an inspection of the cell is done on a regular basis.
6.
CELL AGE -
Normally a WATERMAID cell will have a minimum life of
5
or more years.
Cells beyond this age may deteriorate and result in less chlorine being produced from the cell.
This is also indicated by the LED readout dropping below 100% and therefore less chlorine being
produced.
When salt levels are maintained within the correct range but the LED readout is low, the cell is
clean and the cell is beyond 5 years of age, a NEW cell may be needed to produce sufficient
amounts of chlorine for the pool.
