6 1 Regular checks
-Periodically check the water pressure in the heating
circuit (refer to the pressure level recommended by the
installer - between 1 and 2 bar)
-
If you need to fill up and reset the pressure, check the
type of fluid originally used (if in doubt, contact your
installer)
"
If frequent refills are required it is essential that
you look for any leaks
"
The frequent supply of water risks causing
scale to build up within the heat exchanger and
degrade its performance and life
-If error
Er 76
is displayed: Call your installer
6 2 Outdoor unit check
Remove any dust from the exchanger making sure you
do not damage the blades
Check that there is nothing hindering the air flow.
"
Always check that the electric power supply is switched off before maintaining the boiler
