• HEATING lamp – indicates heating elements are on. Cycle on/off when
in drying mode.
• FAULT lamp – unit has a fault
To start the dehumidifier, turn the On / Off switch to position M.
After a slight delay the fans will operate – air can be felt blowing from the air
outlets and the heater will come on.
The unit will operate continuously at this setting.
If an external humidistat control is fitted, turn the unit to switch to position A.
Depending on the setting of the humidistat, the dehumidifier may switch off as
the relative humidity in the room decreases. As the humidity increase the unit
will automatically switch back on.
High Temperature Cut-Out:
The DD700 dehumidifier has been designed to work in ambient conditions of
-4ºF to +104ºF. Should the temperature in the room become excessive a
manual overheat protector will operate, switching off the heaters. The fans
and drive motor will continue to operate but the fault lamp will illuminate. Prior
to resetting the protector, check that the dehumidifier is installed correctly and
the ambient temperature does not exceed 104°F.
See repairs section for details on resetting device.
