1 The humidity in that room is
lower than 40% r.h. .
The effort of the dryer is
uneconomical in the case of these
conditions. It is recommended to
disconnect the dryer. Tipp: Put
the built-in hygrostat on an
attainable value (e.g. approx.
50%r.F.), with it the dryer
punctually may switch off.
2
The air filter is soiled
The dryer does not receive air
sufficiently. Clean the filter and/or
install a new one. A soiled air filter
can in the long run lead to
disadvantages at the dryer. Tipp:
Control the filter regularly.
3 The temperature in that
room is lower than +15°C.
In the case of these conditions,
the capacity of DH-types is very
small on account of the design of
the refrigeration components and
the automatic defrosting. We only
recommend DH series for heated
rooms with temperatures >= 15°C.
The dehumidifier shows a
bad and/or no drying
capacity.
