B3. The cell has got a leak around the connectors.
The leak can often be found at the gland of the cell connectors. To check for leaks install the
unit on the pool system & check the gland when the filtration pump is in operation.
B.4 The cell housing is cracked
This cracking can typically occur when the pressure sharply increases in the cell housing. This
high pressure can occur
only if the salt chlorinator is in operation with the isolating valves
closed.
This fault is the consequence of a mistake made by the pool owner having mistakenly closed
the valves and having forgotten to open these valves when the chlorinator was started.
Important: In order to avoid this type of problem, it is strongly advised that a Non return
valve be installed in the pipe work between the cell & the pool return.
B.5 The wall of the housing is not transparent anymore
Overheating of the cell will result in you no longer being able to see through the cell housing to
the cell plates. This overheating occurs when the flow through the cell housing is insufficient.
This lack of flow can happen for the following reasons:
One valve closed or partially closed on the filtration circuit. This will result in the flow to the
cell being blocked or restricted thus causing overheating.
A cell full of scale: If the cell is scaled the flow going through the cell housing is restricted,
more common in the case of the EcoSALT cell.
B.6 Brown or black traces on plastic part of the ESC cell
Brown or black traces on the cell indicate the presence of metals in the water. The water coming
from wells often contain metals that can damage the cell. These traces can also be found in
pools located in close proximity to vineyards which have been treated with copper sulphates.
Davey advises against using water drawn from wells to fill up a swimming pool.
