AXE 3 D UNIT 32 R
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For possible clean-
ing do not use chemical products or wire brushes.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise, bring
it to that value.
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• Check the magnesium anode and replace it if necessary.
A
The boiler casing, control panel and aesthetic parts can be cleaned with a soft
and damp cloth, if necessary soaked in soapy water. Do not use any abrasive
detergents and solvents.
Boiler cleaning
1. Disconnect the power supply to the boiler.
2. Remove the front top and bottom panel.
3. Open the door by undoing the knobs.
4. Clean the inside of the boiler and the entire path of exhaust fumes, using a tube
brush or compressed air.
5. Then close the door, securing it with the knob.
To clean the burner, refer to the Manufacturer's instructions.
4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdown (marked with the letter "A"): to restore
operation just press the RESET button (detail 8 - fig. 1) for 1 second or RESET on the
optional remote timer control if installed; if the boiler fails to restart, it is necessary to elim-
inate the fault indicated by the operation LEDs.
Faults marked with the letter "F" cause temporary shutdowns that are automatically reset
as soon as the value returns within the boiler's normal working range.
