● Exhaust air mode on
PPB 30 K
units with a
button provided by the customer.
●
Select installation locations and models for
the ventilation units to keep noise emissions
down. If possible, avoid:
● sound bridges with the structure. Leave
sufficient distance between the other façade
components.
● disbalances, which arise from different
lengths of control cable.
Observe installation requirements relating to
cable lengths and types.
●
Incorrect measurements if the installation
location of the control and external sensors
is inappropriate. Avoid disturbing influences
and direct sunlight.
●
When using more than 2 ventilation units,
we recommend installing the room air cont-
rol in an electronic switch box to be supplied
by the customer. This provides sufficient
space for the connection of the cables to the
room air control.
●
Quiet changeover noises when the PPB 30
fans change direction of rotation.
Do not install PPB 30 in bedrooms.
● Soffit elements PP 45 LE and PP 45 LEV
cannot be combined with PPB 30 units.
