10.1 Maintenance
Maintenance interventions on the humidifi er should be carried out by
specifi cally qualifi ed staff .
Important
:
before proceeding with any operation:
•
cut off the power supply setting the master switch of the machine to
“OFF”;
•
close the shut-off valve of the water supply line.
•
ON/OFF swithc on the device cuts off power to electronic circuit only,
not to heaters!
10.2 Maintenance operations
Routine maintenance of humidifi ers using tap water provides:
1.
cleaning all the parts that come into contact with water:
a.
feeding solenoid valve;
b.
loading/unloading group:
c.
drain pump;
d.
heaters;
e.
collection tray with lime collection basket (models UR002-
UR013);
2.
boiler gasket replacement.
Non-routine maintenance is carried upon every time scheduled
maintenance request (code “CL” on display). Therefore, it is necessary to
perform complete maintenance of the humidifi er and reset the hour
counter.
10.3 Maintenance frequency
Maintenance frequency depends on the amount of water and steam
generated.

15…25 °f
25…40 °f

Demineralised water
The use of demineralised water minimises maintenances times.
Note
: we recommend you carry out non/routine maintenance at
least once a year, regardless of the operating hours and the data
shown on the hour counter.
10.4 Maintenance of the cylinder-boiler
This operation is necessary as the lime deposits that form inhibit the
exchange of heat between the heating elements and the water.
Warning
:
•
do not use detergents or solvents to clean the components in the
boiler and all other plumbing;
•
do not use metal devices to clean the heating elements;
•
the boiler may be hot! Wait for the boiler to cool down before touching
it or use safety gloves.
To access the boiler:
•
shut down the device and open the breaker of the power supply line;
•
completely empty the boiler from water (see the “Shutdown” section);
•
open and remove the front panel (see chapt. 1).
