densate should not be drained through the "Exhaust air"
connection.

5.5.1 Insulation against condensation
1
Material losses
!
When warm air meets cold surfaces, condensation can
2 result.
f For outdoor air and exhaust air ducts, use vapour f
proof thermally insulated pipes.
f If the supply and extract air ducts are routed f
through unheated rooms, insulate these ducts as
well.
5.5.2 Connecting air ducts to the appliance
f Push the air duct onto the air connection. f
5.5.3 Overflow apertures
Living rooms and bedrooms are only supplied with air. Air is only
extracted from rooms where odours and moisture are generated.
Ensure an unimpeded overflow and consequently air balancing.
Install ventilation grilles in internal doors or walls, or enlarge the
air gap beneath the door to ≥ 8 mm.
5.5.4 Cleaning apertures
f Fit cleaning apertures when installing the air ducts, so f
that the air ducts can be inspected and cleaned at regular
intervals.
