The following table presents failures that do not trigger an error message,
together with indications on their cause and notes on how to eliminate the
sources of trouble.
Failure Cause Remedy
Sealing elements improperly
installed or defective.
Post-evaporation elements
improperly installed or ceramic
plates broken.
Air velocity in the duct is too high
(systems without booster
>2.5 m/s, systems with booster
>4 m/s).
Nominal value of humidity is too
high.
Ambient humidity very low.
The internal sensor of the control
unit is active although an external
sensor is connected.
Set nominal value correctly.
Wait.
Deactivate the internal sensor of
the control unit (see chapter 5.5).
Unstable controller signal. Check controller settings and
adjust controller, as required.
Output limitation active.
System incorrectly dimensioned
(insufficient capacity).
Booster pump defective (insufficient
permeate pressure).
Output limitation active and/or
selected starting point of booster
pump is too high.
Fuse F3 blown.
Water hose(s) between spray valves
and spray nozzles (or hoses inside
the duct) disconnected.
Working pressure is too low.
Spray valve Y6 and/or spray valve
Y7 defective.
Output limitation active.
Mount sealing elements correctly
or replace, as required.
Mount ceramic plates correctly or
replace, as required.
Reduce air velocity in the duct, if
possible, or install booster (consult
your Condair supplier beforehand).
Deactivate output limitation (see
chapter 5.5).
Contact your Condair supplier.
Replace booster pump.
Deactivate output limitation (setting:
100%, see chapter 5.5) and/
or adjust starting point of booster
pump (call service technician).
Replace fuse.
Attach water hose(s).
Check reverse osmosis system
and fully demineralized water
supply conduit.
Replace spray valves.
Deactivate output limitation (setting:
100%, see chapter 5.5).
