solutions
Water in the cylinder turns black
1. minerals in the cylinder have
over concentrated 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.
