Maintenance and service (see "13 Maintenance and service" [ 4 204] )
CAUTION
Water coming out of the valve may be very hot.
WARNING
If the internal wiring is damaged, it has to be replaced by the manufacturer, its
service agent or similarly qualified persons.
CAUTION
Although the water circuit is drained, some water may be spilled when removing the
magnetic filter/dirt separator from the filter housing. ALWAYS clean up spilled water.
CAUTION
To protect the piping connected to the magnetic filter/dirt separator from damage it
is recommended to perform this procedure with the magnetic filter/dirt separator
removed from the unit.
CAUTION
Opening the magnetic filter/dirt separator is ONLY required in case of severe issues.
Preferably this action is never to be done during the complete lifetime of the
magnetic filter/dirt separator.
CAUTION
Check the condition of the O-rings and replace if needed. Apply water to the O-rings
before installation.
CAUTION
Make sure to open the valve (if equipped) towards the expansion vessel, otherwise
the overpressure will be generated.
