Maintenance
WARNING
Electrical shock hazard!
Always disconnect the main power before perform-
ing maintenance on the humidifier!
The humidifier and its cylinder contain live electrical
components and hot surfaces, and therefore all
service and/or maintenance operations must be
performed by expert and qualified personnel, who
are aware of the necessary precautions. Remove the
cylinder from the humidifier only after having
drained it completely using the manual drain"
button or procedure. Check that the model and the
power supply voltage of the new cylinder
correspond to the data on the rating label.
Recommended periodic checks
S
After one hour of operation: Check that there are no
significant water leaks.
S
Every fifteen days or no more than 300 operating
hours: Check operation, that there are no significant
water leaks and the general condition of the cylinder.
Check that during operation there is no arcing between
the electrodes.
S
Every three months or no more than 1000 operating
hours: Check operation, that there are no significant
water leaks and, if necessary, replace the cylinder.
Check that there are no blackened parts of the cylin-
der. If there are blackened parts of the cylinder, check
the condition of the electrodes, and if necessary re-
place the cylinder.
S
Annually or no more than 2500 operating hours: Re-
place the cylinder.
Maintenance of plumbing components
WARNING
When cleaning the plastic components do not use
detergents or solvents.
Cleaning the fill valve
Disconnect the cables and the
hoses. Remove the valve and check the condition of the
inlet filter. Clean, if necessary, with a soft brush and warm
water.
Cleaning the drain pump
Remove the valve body.
Clean, if necessary, with a soft brush and warm water.
Cleaning the drain pan
Clean the drain pan of any
mineral deposits and check that the water flows freely from
the pan to the drain at the drain pump.
Cleaning the supply, fill, and overflow pipes
Check
that the piping is clear of obstructions; clean or replace if
necessary.
After replacing or checking the plumbing, check that all
components have been reconnected correctly using the
proper seals. Re−start the humidifier and perform 2 or 3
cleaning cycles (see section Starting with a new cylin-
der"), then check for any water leaks.
WARNING
Always disconnect the main power before touching
the cylinder in the event of leaks, as current may
flow through the water.
Cylinder maintenance
The life of the cylinder depends on a number of factors, in-
cluding the amount and type of mineral in the water, the
correct use and sizing of the humidifier, and the output, as
well as careful and regular maintenance. Another factor af-
fecting cylinder life is Maximum Productionthe higher
the production rate, the shorter the cylinder life; for this rea-
son, the HCSteam−35 humidifiers is preset from the factory
at 70%. Further reductions in maximum production will ex-
tend cylinder life.
