Maintenance Of Power Supply; Maintenance Of Electrolytic Cell - Davey PoolFresh Installations- Und Betriebsanweisungen

MAINTENANCE OF POWER SUPPLY

Little or no maintenance is normally required. However, it is essential that the wall or post to which the
Unit is installed be sprayed (not the Unit itself) with a good surface type insect repellent periodically since
penetration by insects may cause damage which is not covered by your warranty.
The back of the Unit has been designed as a heat sink. It is normal for this area to become very hot.

MAINTENANCE OF ELECTROLYTIC CELL

The cell is composed of precious materials, and although proper maintenance can prolong its life to the
maximum, eventually the process of electrolysis will wear away its delicate coating, at which time it gradually
ceases to produce chlorine.
Mineral salts and calcium (scale) are deposited on the outer and the inner plates as electrolysis takes place.
This build up – will interfere with the flow of electrical current in the Cell and thus lowers sanitiser production.
It is essential to inspect the Cell regularly and clean when necessary. The rate at which deposits will form on
the cell plates differs with each pool and can be influenced by the following:
• Calcium hardness of the water
• Water Temperature
• pH Control
• Water which has been chlorinated with Calcium hypochlorite for an extended period
• Calcium in the plaster surfaces of a concrete pool
Because these conditions vary so much, check the Cell at least weekly to begin with to see when either
scale or a blue/green soapy substance appears on the plates. You will then be able to determine the cleaning
cycle necessary for your pool (obviously more in summer). The intervals between cleaning could get longer
to the point where cleaning is only necessary a few times each year. One exception is the use of bore water
or ground water, in which case cleaning may always need to be as frequent as once a week.
NOTE: In areas with hard water, reverse polarity systems may require occasional manual cleaning.
The life of Davey electrolytic cells vary substantially from one installation to another due to variations in
operating time, water quality and composition, system and cell maintenance. Please ensure that when cell
replacement is necessary you use the correct genuine Davey replacement cell to match your system.
Refer to your local Davey dealer for the correct cell for your model.
