INSTALLATION INSTRUCTIONS
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 hold the hair dryer
too close to the appliance, which could damage the seal.
A distance of approximately 10 cm should be suitable.
When completed, allow the seal and door to cool before
touching them. Once done, the seal should remain in
position.
