SCOPE OF DELIVERY

Unit KWL EC 45
The simultaneous use of controlled ventilation (KWL units) and room-air dependent fireplaces (tiled stove, gas-fired boi-
ler, etc.), requires the observance of all applicable rules. In apartments, which are airtight according to the state of tech-
nology, a room-air dependent fireplace may only be operated with a separate combustion air supply; KWL units and
fireplaces can only be operated based on demand when they are decoupled.
The relevant applicable rules for the joint operation of fireplaces, ventilation, extraction hoods (Federal Association of
Chimney Sweeps (ZIV)) must be observed!
General building regulation requirements
The ventilation units with heat recovery KWL EC 45 can only be installed and operated in rooms with other room air-
dependent fireplaces if the exhaust duct is monitored by special safety devices, which switch off the ventilation unit
when activated (e.g. temperature thermostat with electrical connection to the ventilation unit with heat recovery), thus
the KWL unit will be switched off during the "combustion period". Otherwise, it must be ensured that the underpressu-
re does not exceed 4 Pa in the residential unit by operating the ventilation unit.
The ventilation unit with heat recovery KWL EC 45 must not be operated at the same time as solid fuel fireplaces and
not in residential units with room air-dependent fireplaces, which are connected to multiple exhaust systems. Any exi-
sting combustion air ducts and exhaust systems for solid fuel fireplaces must be capable of being shut off for the pro-
per operation of the ventilation system established with a ventilation unit with heat recovery KWL EC 45.

Protection against contact

The ventilation units are delivered with a fan protection guard as standard.

2.10 Motor protection device

The ventilation units have an energy-saving, maintenance-free EC motor (interference-free, ball bearing-mounted)
with the highest efficiency factor., blocking protection and electronic restart.
3.0 Scope of delivery
Leave the unit in its packaging until just before the respective installation step or installation in order to prevent any pos-
sible damage and contamination.
