Zehnder recommends a maintenance contract with
a specialist ventilation maintenance company. Some
installers provide a maintenance contract in which
the user maintenance can be integrated. Contact the
supplier of the unit for a list of registered installers
nearby.
The warranty becomes invalid if:
■
Parts are used that have not been supplied by
the manufacturer;
■
The unit is used without filters.
Do not disconnect the power to the
unit, unless instructed otherwise in
the manual. This can lead to a build-
up of moisture and result in problems
with mould.
Perform the maintenance tasks within the
suggested time periods. Failure to do this can
result in the ventilation systems performance to
be compromised.
Keep a clearance in front of the unit of at
least 1m. This room is needed to carry out the
maintenance activities.

5.1 Fill the condensation drain
The condensation drain is connected to the domestic
waste-water system. To prevent sewer smells from
entering your home, the water seal of the domestic
waste-water system must always contain water. You
can achieve this by pouring a cup of water into the
water seal.
5.2 Clean the operating device
Activate the child lock on the display, to prevent
any changes to the settings caused by accidentally
pressing the buttons. Clean any operating device
present in your home at least every six months. Use
a dry duster or vacuum cleaner to remove the dust.
Do not use water or any other liquid.
5.3 Clean the grilles
Clean any grille present in and
outside your home at least every six
months.
1. Keep hold of the grille on its outer edge and
pull it completely out of the wall or ceiling (if not
screwed down).
2. Clean the grille with a soft brush or vacuum
cleaner.
3. Clean the filter behind the grille (if present) with a
soft brush or vacuum cleaner.
■
Do not remove the foam behind the grille (if
present) as it would negatively influence the
system performance.
4. Place the grille back in the wall or ceiling.
