5.1. Maintenance activities
In order to ensure optimal operation of the unit, a number of checks
and inspections should be carried out on the unit ar regular intervals,
preferably yearly. This maintenance shall be carried out by the
installer or service agent. Refer to the installation manual for more
details.
The only maintenance which may be required by the operator is:
■
keeping the remote controller clean by means of a soft damp
cloth,
■
checking if the water pressure indicated on the manometer is
above 1 bar.
If the supply cord is damaged, it must be replaced by the
manufacturer, its agent or similar qualified persons in order
to avoid hazards.
During longer periods of standstill, e.g. during summer with
a heating only application, it is very important NOT TO
SWITCH OFF THE POWER SUPPLY towards the unit.
Switching off the power supply stops the automatic
repetitive movement of the pump in order to prevent it from
getting jammed.
