Low Salinity Indicator and Cut-Out
Your ECO-matic is fitted with a number of protective features including the Low Salinity Indicator and a Cut-Out feature.
As the salt level in the pool decreases, the wear on the ‘Cell’ increases. Although salt is not consumed in the ECO-matic
process, it is lost through splashing, back-washing and on bathers as they leave the pool. The salt level is also reduced
by rain, which causes dilution. Salt is not lost to evaporation. As the salt level in the pool falls toward the minimum,
LED
2 will turn RED. At this point the salt level should be increased by adding approximately 50 lbs of salt per 5000 gallons
of water. If no action is taken and the salt level continues to fall, the Low Salinity Cut-Out will activate and LED 1 will
also turn RED. It is advisable to satisfy yourself that the salt level is in fact low, prior to adding salt, as LEDs 1 and 2 can
activate for reasons other than ‘low salt’. Salt Tests Strips can be used to confirm the salt level in the water. If you have
no means of measuring salt level, add the suggested amount of salt and dissolve it by vacuuming or sweeping onto floor
drain. If the LED indicators do not change, the salt level in the water MUST be measured prior to adding additional salt
(take a sample to your local ECO-matic Dealer for testing). This will prevent adding too much salt when ‘low salt’ may not
be the problem.
When the Cut-Out feature activates, the ECO-matic will no longer produce sanitizer, but will switch itself ON a number of
times each hour and assess whether the problem(s) (low salt for example) have been corrected. If the problem still exists,
the unit will switch OFF once again.
Other factors which can activate the
Cut-Out feature:
1. Heavy Rain - can cause very dilute pool water to pass over the ‘Cell’ due to surface skimming. The Unit will turn
back ON after the rain has been mixed into the water unless the salt level has been reduced by dilution/overflow.
2. Scaled ‘Cell’ - a scaled ‘Cell’ will not draw as much electrical current as a clean ‘Cell’ when first started. This will
cause the Cut-Out to operate. This is very beneficial as a scaled ‘Cell’ can cause an overload if it is operated for a
few hours. Heavy scale build-up also increases the wear on the ‘Cell’.
3. Cold Water - cold pool water reduces the ability of a ‘Cell’ to carry electrical current. (Refer Winter Mode below).
4. Failing ‘Cell’ - as ‘Cell’ ages there will come a time when the electrical current draw will drop. This can be
compensated for with the addition of extra salt. A ‘Cell’ is considered failed when it draws less than 80% of
maximum current. To keep a failed ‘Cell’ in operation, Winter Mode can be used along with extra salt. There will
come a time when the ‘Cell’ will not respond to either extra salt or Winter Mode . It will then need to be replaced.
Winter Mode
When the ‘Cell’ draws electrical current from the Power Supply, the amount of current drawn is dependent upon a number
of factors. Two of these factors are
Salinity and Water Temperature .
The Low Salinity Indicator and/or Cut-Out on your ECO-matic are designed to operate at swimming season water
temperatures. When the pool begins to cool in the off season the temperature drop causes the ‘Cell’ to behave differently
– it will draw less electrical current. This can cause the
Low Salinity Indicator and/or Cut-Out to assume that the salinity
has fallen even if the salinity has remained relatively constant.
When the temperature of the pool water drops (typically when it is too cold to swim), the
Winter Mode Switch should be
placed in the ON position. The Winter Mode Indicator will then be ON.
Winter Mode setting has two effects:
1. It alters the setting of the
Low Salinity Indicator
and/or
Cut-Out
.
2. It reduces the Cell Output by approximately 15%.
The Unit will now respond to a cold pool environment. Winter Mode should not be used in the swimming season as it
reduces the Cell Output , leading to less sanitizer, and it alters the setting of the Low Salinity Indicator and/or Cut-Out ,
which could lead to premature ‘Cell’ failure.
