Intended Use of the Device

The ventilation unit is intended for the ventilation of living and recreation rooms. The ventilation unit
can be installed vertically on a wall or horizontally under a ceiling. If necessary, condensate connec-
tions / condensate drains must be provided according to the installation situation. The necessity of
condensation drains must be checked on site or, in case of doubt, provided for safety reasons. Ac-
cording to PHI criteria (Passive House), among others, condensate is to be expected (observe unit
settings).
It may be necessary to ventilate temporarily via windows and/or doors.
Proper use also includes observing all instructions in the installation instructions and this document.
Make sure that the device is permanently sealed and leakage-free. All sealing surfaces must be
clean, dry and undamaged. Sealing materials must not be damaged and all screw connections must
be tightened firmly. The device must be checked for external tightness after closing.
All hose connections and the filter cover must also be airtight.
In case of leakage, condensate can form which can cause further damage, e.g. to the building, the
unit or the furnishings.
Make sure that the heat exchanger is inserted correctly and is not tilted. All sealing surfaces must be
clean and undamaged. The heat exchanger must be checked for damage before installation. Operati-
on without heat exchanger is not permitted.
All unit filters must be replaced regularly. After visual indication or after three months at the latest all
filters must be checked and replaced if necessary. Operation without filters is not permitted.
The operation of the unit can lead to negative pressures in the building and especially in the exhaust
air rooms. Depending on the control setting, the achievable negative pressures can vary
considerably. It may be necessary to check/accept the possible negative pressures (e.g. by the
chimney sweep).

External Insulation and Pipe Insulation

Below 16°C at the installation site, vapour diffusion-tight insulation may be necessary to prevent
condensation on the outside of the ventilation unit.
In heated rooms with high humidity, condensation can form in the area of the outside and outgoing
air on the outside of the unit. In this case as well, vapour diffusion-proof insulation on the outside of
the unit may be necessary.
Sufficient air circulation around the unit must always be ensured. The unit must not touch a surface
with one or more sides of the unit, there must always be an air gap of at least 5 mm.
To avoid condensation on the outdoor and outgoing air lines, these must be insulated by the custo-
mer. The minimum insulation thicknesses according to DIN 1946-6 or similar must be observed.
If air ducts run through unheated rooms, these must also be insulated.

Condensate Drain

The necessity of a condensate drain must be checked on site. If in doubt, a condensate drain must
be provided for safety reasons (provide optionally available condensate trays depending on the in-
stallation position).
The condensate drain and the associated siphon (or similar) must be serviced regularly and checked
for proper water drainage and tightness. The siphon connection must be pressure-neutral.
Ideally, the condensate drain is carried out "dripping" via a funnel siphon.
The condensate drain must be designed with a continuous slope of at least 5 % and must not exceed
a length of 1.5 m.
Possibly, a trace heating at the siphon and/or the condensate drains is necessary if the temperatures
allow freezing or icing.
