TECHNICAL ASSISTANCE MANUAL
for AT 3000, NOVAP 3000 and RC/DC 3000 series
Introduction:
Each humidifier is entirely tested before leaving production. When a deviation occurs or
when the humidifier seems not to be working correctly, the problem is generally only sought
at the humidifier itself, though the deviation is rather often caused by a problem in the
installation of the humidifier. The specialist knows that he must also look at how the steam
pipe has been laid, at the drainage pipe, at the water connection, at the electric
connections, at the humidity controller and sometimes also at the type of water that is used.
You should proceed in the following order:
• observe
• work out the problem
• take action
Important:
This manual should aDlwataaySshebeet4Uu.sceodm along with the operating instructions of DataShee
the respective unit. A diagnosis should only be carried out by a specialist who
follows the recommendations of the operating instructions.

(m) Check processor PCB
For this PCB, a diagnosis can only be done at the factory by the manufacturer. On
site, first exchange the print by a spare PCB you have in your stock.
(n) Steam distribution pipe installed incorrectly
Check installation instructions and install correctly.
(o) Condensate hose not draining
Check for clogging or sharp bent. Verify the positive fall to drain. Check if the duct
is not below atmospheric pressure.
(p) Foam in cylinder
Foam is generally caused by chemicals that entered the cylinder through treated
water or because of using water intake-, steam or condensate hoses which contain
lubricants. Check the quality of the water and that of the hoses. Drain and flush
steam cylinder and flush intake hose. Use Nordmann steam- and condensate hose
as they are free of lubricants. Use normal tap water.
(q) Message of max. water level (S = 1 in service level of AT 3000 or red flash in
the green continuous of the LED with NOVAP 3000 and RC/DC 3000)
Unplug max. level sensor from the cylinder, wait 2 minutes, max. level indication
should extinguish and cylinder should start filling when filling is required.
If the message is still there, disconnect the wire on terminal 2 of the current
transformer and wait 2 minutDeast.aSThheeet4laUm.cpomshould then extinguish and the cylinder DataShee
should start filling. If not, then replace current transformer.
(r) Check for correct inlet valve body or any clogging of valve inlet.
(s) Check for too high duct pressure (max. 1000 Pa) , for too long steam hoses
(should be less than 4 m long), too small diameter of steam hose, sharp bents or
clogged exhaust holes of the distribution pipe in the duct.
(t) There may be air in the supply water pipe
(u) Check if the proportional adaptor is fitted correctly, check external wiring
connections and if a control signal is sent by the humidity controller.
(v) - water level too low in the steam cylinder, refer also to (s).
- too conductive water because of the use of softened water (ion exchanging
method) with conductivity above 1250 microsiemens/cm.
- too conductive water because cylinder does not drain, refer to (k),(l),(m),or
because cylinder is spent and full of minerals.
(w) This signal appears if a replacement electronic controls unit has been fitted to
the humidifier without being coded. The humidifier is prevented from operating.
The signal disappears as soon as the electronic controls unit has been coded.
