Notes for external dispensers:
-
if
the detergent dispenser
only
operates during
wash pump
operation; terminals
7-9
of the main terminal board are powered at the
same time.
-
if
the detergent dispenser
only
operates during
filling electrovalve
operation for
restoring the boiler level; terminals
7-9
of the main
terminal board are powered at the same time.
For connections, see the wiring diagram.
Example:
Supposing that an external detergent dispenser has
been connected with a tank concentration measuring
sensor, a standard setting could be as follows:
the dispenser is not activated during filling of
the tank.
the dispenser is activated during wash
pump operation and, thanks to the concentration
measured by the conduction sensor, the correct
amount of detergent is dispensed.
Changing the detergent type.
If changing to a
different detergent type
(even one by
the same manufacturer), you must rinse the suction
and pressure hoses with fresh water before connecting
the new detergent container. Otherwise, the mixing of
different types of detergent will cause crystallisation,
which may result in a breakdown of the dosing pump.
Failure to observe this condition will invalidate the gua-
rantee and product liability.
