Possible cause:
The operating temperature inside the device is too high (>
65°C).
Counter measures:
– The device should be switched off immediately.
– Check whether the air flow into the device is restricted.
Also make sure that the device has a sufficient
clearance to other objects (wall, cupboard, etc.).
– It may be necessary to replace the device inlet filter in
the back wall of the device. Further information
concerning this matter can be found in the section
“Maintenance”.
NOTE!
For protection, the oxygen supply is set after a further
waiting period and the error code "nOP" is displayed.
However, the compressor continues to run.
Checking the alarm function:
– Temporary blockage of the exhaust opening.
NOTE!
If the internal temperature exceeds 84°C, the
temperature fuse is activated and shuts off the
device. In this case, contact your service provider.
