4. Safety instructions and warnings
7
In the event of a fire, there is a risk
of the fire spreading:
●
if an incorrect connection duct is
connected to the ER housing. Always use
the right duct material for the ER housing
chapter 10.1.
●
If an incorrect ceiling compound is used
for exhaust air systems with an
intermediate ceiling
(ceiling barrier
system)
. Ensure that the gap remaining
between the main duct and wall or ceiling
is fully sealed with non-flammable
materials resistant to deformation, such as
concrete, cement mortar or plaster.
5. Operating the fan
ER EC fans run
at 30 m³/h in base load
operation
(factory setting).
A light switch or separate switch can be used
to switch to
full load operation with 60 m³/h
.
The fan control is located in the cover: ER-
AK, ER-AH and ER-AB have automatic
functions with unit parameters that can be set
chapter 6.4.
●
ER-A
: Standard model
●
ER-AK:
Comfort model
●
ER-AH:
Model with humidity control,
barrier-free
●
ER-AB:
Model with motion sensor, barrier-
free
For full load operation, a
start delay
of 60
seconds and an
overrun time
of 15 minutes
are specified
at the factory
.
If the fan is switched on and off
manually, function in accordance
with DIN 18017-3 is not always
ensured.
Ensure sufficient supply air during
operation.
