problem causes solutions
Water in the cylinder turns black
1. minerals in the cylinder have
overconcentrated and are
deteriorating the electrodes.
1. Check for sags & kinks that
could trap condensate in the steam
hoses that could cause a back
pressure on the cylinder.
2. Check the duct static pressure.
3. Check the fill valve and inlet
strainer.
4. Check the drain valve operation.
5. Correct installation problems
and replace cylinder.
Heavy arcing occurs within hours
of startup
1. The feed water contains large
amounts of Iron, Copper or other
conductive contaminants.
1. Contact the factory for an
optional drain timer to force
additional drains to control the
minerals.
2. If you are using a softener,
check the salt being used. If it
contains any additives, discontinue
use, flush all lines and convert to
pure salt or unsoftened water.
3. Check the electrodes in the
cylinder to be sure they were not
damaged in shipping.
Humidifier continuously fills and
drains without producing steam
1. Mineral has bridged between the
electrodes.
2. There is back pressure from the
steam hoses or duct.
3. The flow regulator in the fill valve
is broken or out of place.
4. Water conductivity is very high.
5. Water is foaming excessively.
1. Clean or replace the cylinder.
2. Check the steam hoses for kinks
or gullys that might be trapping
condensate.
3. Replace the fill valve.
4. Consider using a mix of
demineralized water with raw
water.
5. Check cylinder - replace if
exhausted. If feed water contains
silica or nitrates, install a 1 micron
water filter.
Resetting Factory Defaults
If errors have occurred when setting the parameters, the
controller may be reset to the factory default values:
•
in the first 5 seconds from start-up (while the three
dashes are displayed), press the PRG button (2) until
the upper dash in the center flashes (1);
•
release the PRG button within 3 seconds to confirm
the permanent reset of the factory defaults; to confirm
the reset, the upper dash will stay on for 2 seconds;
•
the factory reset is not carried out if the PRG button is
pressed for more than 3 seconds, until the upper dash
disappears.
Recalling the default parameters does not change the parameter relating to the unit of measure (A1), and it is thus
recommended to check and if necessary select and save the unit of measure as required, and then recall the
default parameters. In this way the default values will automatically be converted.
