6. TROUBLE SHOOTING

Causes
1. No electrical power
2. On/off switch of the humidifier in position 0
(open)
3. Control connectors improperly connected
4. Blown fuses
5. Transformer failure
1. Remote ON/OFF 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 sensor/s higher than
the corresponding set point
1. High steam back pressure
2. Fill valve strainer clogged
3. Mineral in the fill cup
4. Drain pump valve leaking
1. The distributor is not installed correctly (too
near the top of the duct or the condensate return
is blocked)
2.Air flow rate is too low
3.Humidifier active when the fan in the duct is off
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
5. The bushing and / or O-ring at the base of the
cylinder are missing or not properly seated.
Causes
1. Minerals in the cylinder
concentrated and are deteriorating
electrodes.
1. The feed water contains large amounts of Iron,
Copper or other conductive contaminants.
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. Check the safety devices upstream from the humidifier
and the presence of power
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
1. Close ON/OFF contacts
2. Check the external connection
3. Replace the humidistat
1. Check that the steam hose is not kinked or sagging,
trapping condensate
2. Clean the fill valve strainer
3. Clean the fill cup
4. Check for voltage at the drain pump valve and/or drain
pump replacement
1. Check that the steam distributor is installed correctly
2. Increase air flow in duct or decrease PO maximum steam
production setting
3. Check the connection of the device (flow switch or
differential pressure switch) controlling the humidifier to the
ventilation in the duct
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 drain pan
4. Check the fastening of the hose clamps on the steam
outlet
5. Lift out the cylinder and check to see the bushing and / or
O-ring are properly seated. See illustration page 21.
have over- 1. Check for sags & kinks that could trap condensate in the
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 pump operation.
5. Correct installation problems and replace cylinder.
1. Contact the factory for an optional drain timer to force
additional drains to control the minerals.
2. If you are using a softener. Discontinue use.
3. Check the electrodes in the cylinder to be sure they were
not damaged in shipping.
1. Clean or replace the cylinder.
2. Check the steam hoses for kinks or gullies 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.
