9.6 Cleaning and maintenance of the other
components
•
when cleaning plastic components do not use detergents or solvents;
•
scale can be removed using a solution of 20% acetic acid and then
rinsing with water.
Maintenance checks on other components:
□
fi ll solenoid valve. After having disconnected the cables and the
tubing, remove the solenoid valve and make sure the inlet fi lter is
clean; if necessary, clean with water and a soft brush;
□
manifold with drain pump. Check that there are no solid residues
in the cylinder attachment, remove any impurities. Check that the
gasket (o-ring) is not damaged or cracked, replace if necessary. Check
that there are no solid residues in the drain hose;
□
drain pump. Disconnect the power supply, remove the pump and
clean any impurities. Clean the tank from any deposits and check that
the water fl ows freely from the tank to the drain (corresponding to
the drain pump);
□
fi ll tank. Check that there are no obstructions or solid particles and
that the conductivity measuring electrodes are clean, remove any
impurities and rinse;
□
internal tubing kit. Check that the pipes and hoses are free and clear
of impurities, remove any impurities and rinse.
Important: after having replaced or checked the water circuit,
make sure that the connections are tight. Restart the unit and run
a number of fi ll and drain cycles (from 2 to 4), after which, applying the
safety procedure, check for any water leaks.
