• Make sure you keep an appropriate
distance between the sides of the
appliance to ensure total accessibility
for servicing.
• The appliance must be mounted on a
flat wall, which is sufficiently robust to
take its weight.
• The appliance is room sealed, so when
it is installed in a room or space, a
permanent air vent is not required.
• Do not install the appliance above
another appliance that could damage
it (for example, above a cooker that
might emit steam or grease) or in a
room, which has a lot of dust in the
atmosphere which is corrosive.
