Cleaning the air diffusers
The building's air diffusers must be
cleaned regularly in order to maintain
correct ventilation. Use a dry cloth
and/or a small brush to reach inside the
opening of the diffuser. It can also be
taken down if that makes cleaning
easier. Use a duster or a dry cloth to
remove possible dirt marks in the ceiling
around the device.
NOTE! The air diffuser's setting must not be
changed. If taken down, each diffuser must be
returned to its original place.
Cleaning the duct system
The exhaust air ducts - and sometimes the supply
air ducts as well - may need cleaning at long
intervals. Dust and dirt will deteriorate the capacity
of the AHU if not removed.
Authorized
ventilation
cleaners should
carry out the
cleaning.
However, you
yourself can
easily clean the
part of the duct
which is close to
the air diffusers.
Take down the diffuser. Use a vacuum cleaner or
duster to clean the inner part of the duct as far as
you can reach. Refit the diffuser, making sure the
setting is not changed.
Checking the outdoor air intake
Once a year the outdoor air intake should be
checked. Make sure it is not clogged by for
example leaves, snow or ice.
Service
Service and repairs, beyond normal maintenance,
should be carried out by professionals in the
ventilation field, or - if electricity is involved - by an
authorized electrician.
The electric panel must not be opened by
other than authorized specialist.
The plates covering the fans must not be
removed when the AHU is running, as there is
a risk of contact with moving parts. Make sure
the electricity has been cut off (unplugged or
fuse removed).
Interferance with
the AHU system
may affect
the warranty terms.
Use original spare parts only.
Disposal
Prevent accidents when the AHU is disposed of.
Remove the cable from the wall socket and cut it as
close to the unit as possible. Store and transport
the waste unit lying down.
Please leave the unit to be recycled where such
facilities exist. Check with your local authority for
recycling advice.
