Day To Day Operation - Davey PoolFresh Installations- Und Betriebsanweisungen

DAY TO DAY OPERATION

Four Prime rules must be observed if your unit is to give the best possible service:
1. STABILISER
FOR OUTDOOR USE
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
dramatically. 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 stabilisers, have your pool water analysed at your
pool shop to ensure that you do not add too much.
If you use an ORP controller, the stabiliser should not exceed 15ppm.
FOR INDOOR USE
Stabiliser is NOT needed for indoor pools and as such should not be used.
Please consult your local Davey Dealer for more information on stabilising your pool.
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 – 7.0 to 7.4. Other
pools – 7.2 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. To lower the pH add HYDROCHLORIC ACID. To raise the pH levels add
SODIUM BICARBONATE OR SODA ASH.
Total Alkalinity should not be confused with pH, although the two are closely related. Total Alkalinity
determines the speed and ease of pH change. It is measured in ppm – 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.
To lower add HYDROCHLORIC ACID (a little at a time). To raise add SODIUM BICARBONATE.
3. SALT LEVELS
The salt level MUST NEVER BE LESS THAN 3000 ppm (3g/l). The ideal operating salt level is 4500ppm
(4,5 g/l). Operating the Unit with too little salt in the pool will cause damage to your Cell. For PoolFresh units
salinity must not exceed 6000ppm.
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 PoolFresh chlorinator, and insufficient salt will damage your Cell.
Low salt levels will destroy the coating on the cell's Anode materials and will void all Warranty.
The PoolFresh chlorinator has a built in warning system to minimise damage resulting from insufficient salt
levels, however, the ultimate responsibility is on the owner to ensure adequate salt levels are maintained all
year round.
NOTE: Swimming pools contain water with a low level of salinity, free chlorine and other
compounds. Any materials in contact with the pool water should be suitable for this environment.
Davey Water Products SAS can not be held responsible for damages that occur to the materials
of other products that come into contact with the water of the pool.
4. RUNNING TIMES & CHLORINE PRODUCTION
These instructions cover PoolFresh in residential use only.
If you run your chlorinator for 24 hours a day, or for long periods, the Cell life will be reduced dramatically. It is
important that the correct model chlorinator has been installed on your pool. (Consult your local Davey Dealer for
more information).
