6. TROUBLESHOOTING
Problem Cause Solution
The humidifi er does not start 1. No electrical power
2. Humidifi er ON/OFF switch in position 0 (off )
3. Control connectors badly connected
4. Broken
fuses
5. Controller fault
1. Check the protection devices upstream from the
humidifi er and the presence of power
2. Close the ON/OFF switch: position I (on)
3. Check that the connectors are properly inserted in the
terminal block
4. Check the condition of the fuses
5. Check that this is activated and the correct voltage is
connected
The humidifi er does not start 1. Remote ON/OFF contact open
2. The humidistat has not been connected correctly
3. Humidistat
fault
4. Control signal not compatible with the type set (see
note 5.11)
5. Value measured by the sensor/sensors higher than the
corresponding set point
1. Close the ON/OFF contacts (terminals AB-AB)
2. Check the external connections
3. Replace the humidistat
The humidifi er fi lls with water
without producing steam 1. High steam backpressure
2. Fill valve fi lter blocked
3. Minerals in the fi ll tank
4. Leaks from the drain pump 1. Check that the steam hose is not twisted or curved
downwards, thus trapping the condensate
2. Clean the fi ll valve fi lter
3. Clean the fi ll tank
4.
Check the voltage on the drain pump and/or replace the
drain pump
The humidifi er wets the duct 1. Distributor not installed correctly (too near the top of the
duct or the condensate return is blocked)
2. System oversized
3. Humidifi er active when the fan in the duct is off
1. Check that the steam distributor is installed correctly
2. Decrease the set steam production
3. Check the connection of the device (fl ow switch or
diff erential pressure switch) slaving the humidifi er to
the fan in the duct
The humidifi er wets the fl oor
below 1. Humidifi er drain blocked
2. The supply water or overfl ow circuit has leaks
3. The condensate drain hose pipe does not carry the
water to the tank
4. The steam hose is not fastened to the cylinder correctly
1. Clean the drain circuit and the fi ll tank
2. Check the entire water circuit
3.
Check the correct position of the condensate drain hose
in the drain tank
4. Check the fastening of the hose clamps on the steam
outlet
Sparks form inside the cylinder a
few hours after starting 1. The supply water contains considerable quantities of
iron, copper or other conductive contaminants.
1. If using a softener, check the salts used. If these contain
additives, stop use, rinse all the lines and use non-
softened water.
2. Check the electrodes in the cylinder to make sure they
have not been damaged during transport.
The cylinder fi lls with water and
drains continually, without produ-
cing steam 1. The minerals have formed a bridge between the
electrodes.
2. Backpressure from the steam hoses or the duct.
3. The fl ow controller on the fi ll valve is broken or not
calibrated.
4. High conductivity of the water.
5. Excessive foam forms.
1. Replace the cylinder.
2. Check if the steam hoses have twists or sags that may
trap the condensate.
3. Replace the fi ll valve.
4. Consider using a mixture of demineralised water and
untreated water.
5. Check the cylinder and replace it if exhausted.
