Day To Day Operation - Davey EcoSalt 2 DES2-25EL Installations- Und Betriebsanweisungen

Method two:
As an alternative, an approved commercial cell cleaning solution can be used a number of times effectively.
NOTE: Always add acid to water. Never add water, to acid. Always wear eye protection
and rubber gloves. Always clean the cell in a well-ventilated area.
RE-INSTALLING CELL AFTER CLEANING OR REPLACEMENT
When re-installing the Eco-Salt2 cell into the in-line housing, ensure that the cell locking nut is tight. Do this
by turning on the pool pump once fitted, then checking for leaks.
If there is a leak, remove the lock nut and inspect the o-ring for debris, or damage. Then re-try. Before re-
fitting the cell connectors, ensure that the terminals are dry.
SAFETY DEVICE
Hydrogen Gas is a by-product of the chlorine producing process. A Flow Switch has been supplied with the
EcoSalt2, which will stop output if low or no flow is detected. The EcoSalt2 system will run to flows down to
3.6m³/h (60L/min).

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 25-50ppm. If a ORP controller is used, Stabiliser should be maintained at a level of
15-25ppm. Before adding more stabiliser, have your pool water analysed at your pool shop to ensure that
you do not add too much. (FOR OUTDOOR POOLS ONLY, INDOOR DO NOT REQUIRE STABILISER)
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, in order to correctly sanitise the pool.
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. An inability to keep the pH constant may cause staining, etching and corrosion of metals. High Total
Alkalinity will cause constantly high pH levels and tends to encourage Calcium scaling.
