Maintenance - Fresh INTELLIVENT 2.0 Installationsanleitung

MAINTENANCE

Fresh Intellivent is designed to work efficiently for many
years. The fan needs to be cleaned at regular intervals if it
EN
is to function properly. These intervals are determined by
duration of fan operation and air quality. Clean the fan at
least twice a year, or as required.
Disconnect the power supply to the fan by pushing the
multi-pole switch up to position O - OFF.
The fan is fitted with a removable propeller. Press in the
centre using your thumb, grip the fan wings and pull off
the propeller. The fan's "swing out" function is also use-
ful, as it provides easy access to the duct. Press the motor
mount ring's snap-in catch and swing out the motor/
blades.
OFF
Clean the duct/pipe if there is any dirt present inside.
Failure to do this may result in a risk of impaired capacity.
When cleaning the fan, pay particular attention to the
blades if these are dirty. Otherwise, there is a risk of
imbalance and hence increased noise and a reduced
life span for the motor bearings.
