DANGER Danger if the relevant regula-
tions for electrical installations are not ob-
served.
Before removing the housing cover or removing
the fan insert and before installing the electrics,
switch off all supply circuits, switch of mains fuse
and secure it against being accidentally switched
back on again. Attach a warning sign in a clearly
visible place.
Be sure to observe the relevant regulations for
electrical installation; e.g. DIN EN 50110-1. In
Germany, particularly observe VDE 0100, with
the corresponding sections.
A mains isolation device with contact openings of
at least 3 mm at each pole is mandatory.
Only connect unit to permanently wired electrical
installation and with NYM-O or NYM-J cables,
depending on the unit variant, 3 x 1.5 mm² or 5 x
1.5 mm².
Units may only be operated using the voltage and
frequency shown on the rating plate.
Unit may be energized even when at a standstill
and may switch on automatically due to sensors
(time delay, humidity etc.). Maintenance and fault
finding only permissible when carried out by qual-
ified electricians.
The degree of protection stated on the rating
plate is only guaranteed if installation is under-
taken correctly and if the connecting cable is cor-
rectly guided through the stepped grommet (The
grommet must completely enclose the cable
sheathing). The fan insert must also be engaged
and the housing cover installed.
DANGER Danger due to fire transmission
if an incorrect connection duct is connected to the
ER housing. Always use the correct duct material
for the respective ER housing.
if incorrect ceiling compound is used for exhaust
air systems with an intermediate ceiling (PAM-
GLOBAL RML or ceiling barrier system). Ensure
that the gap remaining between the main duct
and wall or ceiling is fully sealed with non-flam-
mable materials resistant to deformation, such as
concrete, cement mortar or plaster.
if the seal with the brickwork or wall boards is in-
correct. If used outside the shaft, ensure that the
gap remaining between the connection duct and
brickwork/wall boards is fully sealed with non-
flammable materials resistant to deformation,
such as concrete, cement mortar or plaster and
for the wall boards, special fire protection filler.
if the metal exhaust socket is incorrectly connec-
ted to the connection duct. 3 steel blind rivets are
prescribed for the connection with the exhaust
socket. These must not impair the shutter func-
tion. Before commissioning, ensure that the shut-
off shutter moves with ease.
if the metal shut-off shutter is not correctly inser-
ted and screwed down in the exhaust socket.
During installation, it is essential that the shut-off
shutter is correctly positioned and screwed down.
The soldered strut must be correctly inserted and
the shutter must move with ease.
DANGER Risk of injury in case of dam-
aged unit.
Switch the unit off immediately if you discover
damage or faults that could endanger persons or
property.
Prevent from being switched back on until fully
repaired.
WARNING Risk to health if filters are not
replaced or if there are no air filters.
Heavily soiled or moist air filters can accumulate
harmful substances (mould, germs, etc.). This
may also happen if the unit is shut down for an
extended period. If the air filter is missing, the
unit and air ducts become soiled.
Never operate the unit without air filters.
Only use original filters.
Regularly change air filter when a filter change is
indicated (LED or TimeStrip).
If the unit has not been used for a long time, al-
ways replace the air filters.
