Warning / Fault
Red
4 Humidifier short cycling 4 Observe operation to
ensure humidifier can
normally run long
enough to perform a
drain. If not turn on the
Short Cycle feature on
page 56.
Low Conductivity
Warning Low water
conductivity
1 Drain valve leaking 1 Clean drain valve or
replace (see
maintenance chapter)
2 Back pressure causing
some fill water to go
down drain
2a Check for restrictions
and proper condensate
removal in steam line.
2b If water is going down
drain during fill cycle
then install fill cup
extension kit.
3 Wrong Cylinder Installed 3 Install cylinder of same
model number as was
previously installed
4 Newly installed cylinder
not reaching demand
for extended time due
to Low water
conductivity
4a Add 1/4 teaspoon of
salt to fill cup.
4b Adjust drain factor to
0.7 in User Defined
Settings (see operation
chapter)
4c Turn on the Low
Conductivity feature on
page 56.
Max Level Warning
Water level at
top of cylinder or
foaming
1 Humidifier has filled to
top of cylinder without
reaching demand
1 None, for information
only, it is normal for a
new cylinder to reach
max level before water
in cylinder is
concentrated and for an
old cylinder to reach
max level near the end
of cylinder life.
1b If the cylinder is new,
add ¼ teaspoon of salt
to fill cup to assist
cylinder in
concentrating.
1c Supply water
conductivity too low (DI
or RO). Change to
potable water supply
with conductivity above
150 µS/cm.
