METHOD 2
As an alternative, an approved commercial Cell cleaning solution can be used a number of times effectively.
When clean the Cell should be rinsed thoroughly and the connections should be dried carefully to avoid
connector corrosion. It should not take longer than a few minutes to clean, if it does the Cell should be cleaned
more frequently. Return the Cell to its position in the pipe work and re-connect it.
SAFETY DEVICE:
Hydrogen Gas is a by – product of the chlorine producing process. A Gas Sensor has been incorporated into the
Unit and Cell, which will switch off chlorination if gas is detected in the Cell Housing or there is no water flow.
EcoSalt ™ Units are also fitted with a Thermal Cut – Out to prevent overheating. If the temperature rises too high,
power is automatically disconnected. The Unit will resume operation when it cools down.
DAY TO DAY OPERATION:
Four Prime rules must be observed if your unit is to give the best possible service:
1. STABILISER
The importance of pool stabiliser cannot be over – emphasised. It is essential in helping retain chlorine in your
pool. Chlorine is rapidly dissipated by sunlight and the use of stabiliser will reduce this dissipation substantially.
Without stabiliser, it may be necessary to run the Unit for up to three times as long!
Stabiliser should be added at the rate of 500 grams for every 10,000 litres of water. Stabiliser should be
maintained at a level of 30 – 50 ppm. Before adding more stabiliser, have your pool water analysed at your pool
shop to ensure that you do not add too much.
2. pH AND TOTAL ALKALINITY:
A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water, etc. An
incorrect pH level can damage the pool. Correct pH levels are as follows; Fibreglass – 7.2 to 7.4 Concrete & tiled –
7.4 to 7.6 If you allow the pH level to rise to 8.0 or above, the chlorine required could be as much as three times
the normal amount.
Total Alkalinity should not be confused with pH, although the two are closely related. Total Alkalinity determines
the speed and ease of pH change. The ideal range is 80 – 150 ppm, or refer to your pool professional.
You should use a test kit which includes a test for Total Alkalinity. Low Total Alkalinity can cause unstable pH
levels – i.e. An inability to keep the pH constant may cause staining, etching and corrosion of metals. High Total
Alkalinity will cause constantly high pH levels.
3. SALT LEVELS:
Salt is the essential element by which your Unit operates. Not enough salt means not enough chlorine - this simple
rule governs the total operation of your EcoSalt ™ , and insufficient salt will damage your Cell.
WARNING: Follow safety instructions provided with the Hydrochloric Acid or cleaning solution. When
handling Hydrochloric Acid, the use of eye protection, mask and gloves are highly recommended.
Extreme caution should be taken whenever handling Hydrochloric Acid or Cell Cleaning Solution.
Warning: Some people recommend that you put salt directly in the skimmer box. This is a very
poor practice as it allows very high concentrations of salt to be passed through your filtration and
other pool equipment.
RECOMMENDED SALT LEVEL RANGE: 4500 - 6000ppm
(Above ground pool models only: 2500ppm)
