Danger of
electric shock.
Before removing the internal cover, shut
down all supply circuits (deactivate the mains
fuse) and secure so they cannot be switched
back on. Attach a warning sign in a clearly
visible place.
When internal cover is taken off, ensure
that no spray enters the housing.
Also before changing a filter, switch off
the mains fuse and secure so it cannot be
switched back on. Attach a warning sign in a
clearly visible place.
The board protective covers may only be
removed by trained electricians.
Do not touch any electronic parts
(static charge).
Risks from parts which may affect the
ventilation system which are added or
modified at a later date.
Parts (range hood, air-ventilated fireplace
etc.) which are added or modified at a later
date may result in health risks and operation
which is not permitted.
Parts may only be added or modified at
a later date if system compatibility is estab-
lished/ensured by a planning office. If using
an exhaust air range hood or air-ventilated
fireplace, this must be accepted by a profes-
sional chimney sweep.
Danger if operating a ventilation
unit not mounted in full. If the unit is
open and is being operated without a filter, a
running fan can be touched. Risk of electric
shock from components of the PP 45 RC
unit without electrical protection.
Only operate the ventilation units when
completely installed.
Wait until the fan is stationary.
