Fuses (auxiliary circuits)
These measure 10.3 x 38 mm and are housed in the fuse cartridge; to
check the state of the fuses, check their continuity using a tester. Use the
fuses as specifi ed in the table.

Heaters
To replace the heaters, unmount them removing the fastening nut (D) on
the cover; in this case it is advisable to replace the seal (G).

Note: for sizes 002 - 013, spacers are featured between the heaters
to guarantee correct positioning. Release the spacers to remove the
heaters. After cleaning, reposition the spacers.
PTC temperature sensor
The PTC sensors (one for each heating element) do not require regular
maintenance; they should only be replaced if the safety thermostat is
activated due to operation without water: in fact, the intervention of
just one PTC will cause the control module to shut-down operation. To
replace them, remove the boiler (models UR002-UR013) or the top panel
of the humidifi er (models UR020-UR080) as explained in the previous
paragraphs and then:
•
remove the covers that protect the heaters;
•
disconnect the terminals of the PTC sensor from the terminal block,
remove it from probe housing and replace it;
•
insert the new sensor and restore wiring.
Note : the sensor should be inserted until it reaches the limit
switch.

NTC temperature sensor
The NTC temperature sensor is located in probe housing (P) outside the
boiler, under the insulation (where featured, depending on the model).
