Instructions for use and maintenance of LEX Smart Water Softeners
6. Service / Service interruption
As the water softener works automatically, you only have
to refi ll salt from time to time, but at the latest when the
display signals that the salt level is low. The SYR LEX Smart
control indicates the number of days left until the salt stock
is depleted.
The salt stock should not be reduced to the extent that the
liquid level is above the salt, as otherwise it rises excessively
when refi lling salt. The SYR LEX Smart control will signal a
malfunction.
When no softened water or just a little quantity of softe-
ned water is drawn off, the water softener will automatically
carry out a forced regeneration after 4 days at the latest to
ensure perfect hygiene (in compliance with EN 14743 and DIN
19636-100 (DVGW-test guideline).
When restarting the water softener after a service
interruption, the start-up process has to be carried out again
(cf. the relevant instructions for installation and start-up).
Should the main water supply of the water softener be
interrupted (main shut-off valve closed or on „bypass“),
the power supply of the device has to be interrupted as
well.
