2 Installation conditions
■ The unit must be installed in a frost-free space with
climate zone N (16-32°C).
■ The ventilation unit should be mounted on a support
frame (see under service parts), which should stand
on a stable floor.
Fitting to a ventilation unit mounted
on a wall is NOT permitted for safety
reasons.
■ The following must be available: Ø180mm air duct
connections, 230V electrical connection with sufficient
capacity, and facilities for condensation drainage.
■ The roof vents should be made airtight and damp-
proof.
■ All supply and exhaust ducts should be damp-
proofed. This prevents condensation forming on
the inner or outer duct surface and improves air
temperation efficiency.
■ The exhaust duct should drain in the direction of the
unit.
■ The condensation must be drained off frost-free, at a
gradient and incorporate a 'U' bend.
■ DO NOT connect a powered extractor hood to this
system.
■ We recommend fitting the unit with silencers right up
to the unit, on both the supply and return pipes. For
more information, please contact Zehnder.
■ The installation location must be chosen so that
there is sufficient room around the unit for air duct
connections, intake and exhaust piping and in order
to carry out installation work. Keep at least 1 metre
free in front of the unit. At least 250mm should be
kept free at the side with the condensation drain.
■ The height when mounted should be at least 185cm,
beyond the space required for the duct connection.
