USER’S GUIDE
WHAT TO CHECK ON A REGULAR BASIS
Essential recommendations for the correct operation of the appliance
ACV recommends to check the system at least every 6 months as follows:
•
Check that the system water pressure is at least 1 bar when cold. If the pressure drops
below 0.8 bar, the built-in pressure sensor blocks the appliance until the pressure
exceeds 1.2 bar.
•
If it is required to top up the system to maintain the minimum recommended water
pressure, always turn the appliance off and only add small amounts of water at a time. If a
large amount of cold water is added in a hot boiler, the boiler can be damaged definitively.
•
If the system needs to be refilled repeatedly with water, please contact your installer.
•
Check that there is no water on the floor under the boiler. If there is, please call your installer.
•
If a condensate neutralisation system is installed, check it and have it cleaned regularly.
•
Check regularly that there is no error code (lockout) flashing on the display. Refer to
paragraph below.
