Technical instructions ZELIA ZLT
19
If tarpaulin or a cover is used, the chlorine is protected from UV rays and the chlorine requirement
is reduced. In Automatic mode and when the cover contact point is connected, ZLT automatically
reduces production.
To enable the ZLT to operate with cold water (less than 18°C), it may be necessary to increase the
salt rate to 5g/l.
8.3. Cleaning the cell
When the indicated production is low despite the correct salt rate, the status of the cell should be
checked; if there is visible scale on the plates, the cell should be cleaned. To clean the cell, one end
should be blocked and diluted acid should be poured in (10% HCI recommended). Allow the acid
to act over several hours. This operation must be carried out with the greatest of care and it must
follow the instructions set out for the use of the acid.
