Maintenance of Your ECO-matic (Continued)
Maintaining The Salt Level
The optimum salt levels for best chlorinator efficiency is 4500-5000ppm. It is important to always maintain at least the
minimum recommended salt level of 3500ppmin the pool water. Always monitor and maintain the optimum salt level for
your ECO-matic model.
Operating your ECO-matic at lower than recommended salinity level will shorten the life of your ‘Cell’ and will void
warranties on the ‘Cell’. An excess of salt (up to 6000 ppm) is acceptable and will not harm the ECO-matic (in fact, the
system operates more efficiently at higher salt levels).
Checking The Salt Level
Your ECO-matic has a Low Salt Indicator (LED 2) . When the level of salt in the water falls below the minimum level,
LED 2 will turn RED. The Unit will continue to produce sanitizer, but the situation should be corrected quickly. Otherwise
the
Low Salinity Cut-Out
will shut down the ECO-matic.
The Low Salt Indicator (LSI) has been factory calibrated (plus or minus) to a salt level 3000 ppm so could therefore
activate at slightly higher salinity than the designed minimum salinity. If the LSI activates when you think there is sufficient
salt in the water, a physical test kit measurement of the salinity is necessary.
Salt Test Kits
Various ‘salt’ test kits are available, and less expensive salt test strips can be purchased from your local pool professional.
Some pool shops will test your salt levels.
How Salt Is Lost From Your Pool
The ECO-matic process does not consume the salt – it merely re-uses it over and over. No salt is lost through
evaporation. However, salt is lost from the pool when water is lost – back-flushing filter, splash-out, overflow in rainy
periods, leaks in the pool.
Adding Salt To The Water
Pool salt (sodium chloride) is available in bags of various sizes from your local pool professional. Call your ECO-matic
Dealer if you need assistance in locating a source of salt.
Add the salt by tipping it directly into the pool. Dissolve by sweeping the salt to the deep-end floor drain and/or by
vacuuming the pool. The heavier-than-water saline ‘syrup’ will remain on the floor of the pool if not mixed properly.
Note: Some ECO-matic owners find it convenient to add 5 - 10 lbs of salt after each back-flushing of the filter.
How Much Top-up Salt To Add
When topping-up the salt level, we suggest adding salt at the rate of approx 100 lb per 10,000 gallons of water.
Remember: A slight excess of salt is not a problem, but too little salt causes damage to the ‘Cell’. When the added salt is
dissolved, check that
LED 2 remains GREEN. Measure the salinity if in doubt. DO NOT continue to add salt if LED 1 and/
or LED 2 remain RED. Measure salinity before adding more salt to prevent over-salting the pool.
