4
. Bl own fuses
5. Transformer failure
1. Che c k the s a f et y devi c e s u ps t r eam fro m the humidi fi e r
a n d the pres e nc e of po we r
2
. Close the switch on the panel: position I
3. Check that connectors are properly inserted in terminal block
4
. Check the condition of fuses
5. Check that the proper voltage is connected and turned on
The humidifier does not
start operation
1 . Remote O N/ OF F contact open
2 . The humidistat has not been
connected correctly
3. Humidistat failure
4
. Control signal not compatible with
the type set
5. Value measured by the sensors higher
than the corresponding set point
1 . Close O N/ OF F contacts
2
. Check the ex ternal connection
3. Replace the humidistat
The humidifier fills with
water without producing
steam
1 . High steam back pressure
2 . Fill valve strainer clogged
3. Mineral in the fill cup
4
. Drain solenoid valve leaking
1 . Check that the steam hose is not kinked or sagging,
trapping condens ate
2 . Clean the fill valve strainer
3. Clean the fill cup
4 . Check for voltage at the drain solenoid valve and/or drain
solenoid replacement
The humidifier wets
the duct
1 . The distributor is not installed correctly
(too near the top of the duct or the
condensate return is blocked)
2
. System over-sized
3. Humidifier active when the fan in the
duct is off
1 . Check that the steam distributor is installed correctly
2. Decrease the steam production set on the control
3. Check the connection of the d e vice (flow switch or differential
pressure switch)
the duct.

The humidifier wets the
floor below
1 . The humidifier drain is blocked
2 . The supply water or overflow circuit has
leaks
3. The condensate drain pipe does not
bring the water back to the drain pan
4 . The steam hose is not properly fastened
to the cylinder
1 . Clean the drain assembly and pan
2 . Check the entire water circuit
3. Check the correct position of the condensate drain hose in the

Problem Causes 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 replac e cylinder
Heav y 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 th e cylinder to be sure th e y were not
damaged in shipping
Humidifier continuously
fills and drains without
production steam
1 . Minerals have bridged the electro d es
2
. There is back pressure from the steam
hoses or duct
3. The flow regulator in the fill valve is bro k en
or out of place
4
. Water conductivity is very high
5. Water is foaming e xcessively
1 . Clean or replace th e cylinder
2 . Check the steam hoses for kinks or gullies that might be
trapping condens ate
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
