AIR MOVING SYSTEM:
The DD200 is a single fan balanced system providing both the “Process” air
and “Regeneration” air flow. As the air passes over the rotor, it will be heated
as a result of the regeneration cycle. The air leaving the unit will be hotter
than the air entering
During normal operation some parts of the dehumidifier may become hot. This
is normal.
HIGH TEMPERATURE CUT OUT:
The DD200 dehumidifier has been designed to work in ambient conditions of
-20ºC to +40ºC. Should the temperature in the room become excessive an
overheat protector will operate, switching off the PTC heaters. The fan and
drive motor will continue to operate. This is a manual reset device. Prior to
resetting the protector, check that the dehumidifier is installed correctly and
the ambient temperature does not exceed 40°C.
See repairs section for details on resetting device.
