1.4 Standardised output data
Information on determining and interpreting the specified stand-
ardised output data
Standard: EN 13141-7
The output data specifically mentioned in text, diagrams and
technical datasheet has been determined in line with the test
conditions specified in the standard shown in the heading of this
chapter.
Generally, these standardised test conditions will not fully meet
the conditions found at the installation site of the system user.
Depending on the chosen test method and the extent to which
the selected method deviates from the conditions specified in the
standard shown in the heading of this chapter, any deviations
can have a considerable impact. Additional factors that have an
influence on the test values are the measuring equipment, the
system configuration, the age of the system and the flow rates.
A confirmation of the specified output data can only be obtained
if the conditions applicable to the relevant test match those of the
standard shown in the heading of this chapter.

2. Safety
2.1

Intended use

The appliance is designed as a mechanical ventilation unit with
central supply and extract air routing.
The appliance is intended for domestic use. It can be used safely
by untrained persons.
The appliance can also be used in non-domestic environments,
e.g. in small businesses, as long as it is used in the same way. Any
other use beyond that described shall be deemed inappropriate.
Observation of these instructions and of the instructions for any
accessories used is also part of the correct use of this appliance.
The following are deemed inappropriate:
- Use extract air containing grease, explosive gases, dust or
adhesive aerosols
- Connect cooker hoods or vented tumble dryers to the ventila-
tion system
Never adjust the settings of supply and extract air vents inside the
rooms. These have been set up by a qualified contractor during
commissioning.

General safety instructions

WARNING Injury
!
The appliance may be used by children over 8 years of
age and persons with reduced physical, sensory or men-
tal capabilities or a lack of experience and expertise,
provided that they are supervised or they have been
instructed on how to use the appliance safely and have
understood the potential risks. Children must never play
with the appliance. Cleaning and user maintenance must
not be carried out by children without supervision.
WARNING Injury
!
The discharged cold air can cause condensation to be
formed in the vicinity of the air discharge.
f Ensure that no risk of slipping due to wet conditions
or ice formation occurs on adjacent footpaths and
driveways at low temperatures.

Appliance description

The appliance draws in outdoor air with a fan. A second fan ex-
tracts stale air from the rooms containing odours or moisture,
e.g. kitchen, bathroom, WC. Extract air and outdoor air are routed
through separate air ducts. Extract air and outdoor air are filtered
by separate filters.
The extract air and outdoor air flow through a cross-countercur-
rent heat exchanger. The outdoor air absorbs heat taken from the
extract air. This enables a large proportion of thermal energy to
be recovered.
