VENTILATION THE RIGHT WAY
V E N T I L A T I O N & H E A T R E C O V E R Y
— The ventilation unit must always be freely accessible for operation and maintenance.
►
Make sure that the ventilation unit is not covered or obstructed when the room is
subsequently decorated and furnished, otherwise it cannot be operated and it will
not be possible to replace the air filters. You should therefore maintain a clearance
of at least 15 cm in front of the ventilation unit cover.
►
Make sure that the supply and extract air openings are not covered when the room
is subsequently decorated and furnished, otherwise the ventilation unit’s functions
may be impaired.
2.4
Note on use in conjunction with room air conditioners
Condensation may form in the ventilation unit if the outdoor air temperature and humidity
are high, but the room temperature is cool.
For these conditions, we recommend using the M-WRG-II E ventilation unit with enthalpy
heat exchanger. This has the advantage of removing both sensible and latent heat from
the supply air. As a result, the air is dehumidified as well as being precooled. The room
air conditioner needs to do less work, so the user saves money on the reduced power
consumption.
2.5
Intended use
— The ventilation unit is designed to ventilate living spaces and rooms used for
quasi-residential purposes. The ventilation unit is installed in a perpendicular position
in the external wall. Any different or more extensive usage will be regarded as contrary
to the intended use.
— The intended use also includes compliance with all the notes in the operating instruc-
tions.
—
The ventilation unit must not be operated without air filters or outer wall terminal.
— The ventilation unit is intended for use in rooms with normal room air humidity levels
of approx. 40 % to 70 % RH. It must not be installed in rooms in which the relative
humidity during operation constantly exceeds 80 %.
— The ventilation unit’s functions may be impaired or the unit may be damaged in rooms
with a lot of dust (e.g. model-making) or corrosive gas emissions (e.g. blueprint shop,
cleaning).
—
For any use contrary to the intended use, Meltem Wärmerückgewinnung GmbH & Co. KG
shall accept no liability for any damage that may occur and offers no warranty that the
ventilation unit will work perfectly and correctly.
