CDA FW522 Installation, Use And Maintenance Manual page 19

Ensuring the door seals correctly:
It is normal for the seal to be compressed after the door has been
reversed.
With the door closed, use a hair dryer to expand the seal and fill the
gap between the door and the body of the appliance.
Take care not to use the hair dryer too close to the appliance, which
could damage the seal. A distance of approximately 10cm should be
adequate.
When completed, allow the seal and door to cool before touching them.
Once done, the seal will remain in position.
