When positioning the dehumidifier, ensure that it is placed on a level surface and that there
is a minimum of 10cm of space on either side of the unit to allow for efficient airflow.

We do not recommend the use of an extension lead, so please try to ensure that the unit is
sufficiently close to a fixed main socket. If it is necessary to use an extension lead, please
ensure the diameter of the wires of the cable is at least 1 mm

When the dehumidifier is in operation, outside doors and windows should be closed when
necessary for most efficient use.

Make sure that there is no obstruction around the air inlet and the air outlet. The position of
the air inlet and outlet is as below:
