1 Safety instructions
■ Always obey the safety regulations,
warnings, comments and instructions
given in this document. When
the safety regulations, warnings,
comments and instructions in this
document are not obeyed personal
injury or damage to the unit can
occur;
■ Always obey the general and locally
applicable construction, safety and
installation instructions of the local
council, electricity and water boards
or other agencies;
■ Always connect air ducts of at least
900mm to the unit before you connect
the power to the unit. This ensures the
motor cannot be touched while the
unit is active;
■ After installation all parts that can
cause personal injury are secured
behind the casing. Tools are required
to open the casing;
■ The installation, commissioning and
maintenance must be carried out by
a certified engineer unless instructed
differently. A non-certified engineer
can cause personal injury or damage
the performance of the ventilation
system;
■ Do not modify the unit or the
specifications given in this document.
A modification can cause personal
injury or damage the performance of
the ventilation system;
■ Always disconnect all poles of the
power supply of the unit and optional
connected ComfoSplitter before
you start working on the ventilation
system. The unit can cause personal
injury when it is open while running.
Make sure the unit cannot switch back
on by accident;
■ Often power is needed on the unit
during troubleshooting while the
unit is open. At all times be aware
of the danger for electrical shocks
and rotating parts. Therefore always
take all the possible precautions to
protect yourself and others during
troubleshooting.
■ Always take ESD-inhibiting measures
when dealing with electronics, such as
wearing an antistatic wristband. The
electronics can be damaged by static
charges;

ESD
■ The FIREPLACE setting is no safety
feature. For safety, a delta-pressure
switch switching off the ventilation in
case of under pressure should still be
installed;
■ Do not change the filters when the
unit is powered without using the filter
wizard. For safety reasons the unit will
stop the ventilation during the filter
replacement instructions.
