• The fan must be transported in its packing until
installation. This prevents transport damages, scrat-
ches and the fan from getting dirty
• Attention, look out for sharp edges and corners.
•
Attention!
Temperatures up to 85 °C can be pre-
sent on the controller housing.
•
Waiting period of at least 3 minutes!
Because of internal capasitors, danger of death exists
even after switching off the device through directly
touching the energized parts or due to parts that
have become energized due to faults. The controller
housing may only be removed or opened when the
power line has been switched off and a period of
three minutes has elapsed since switching it off.
• Avoid extreme heat or cold (temperature range for
storage and transport.
• Avoid prolonged storage; we recommend a maxi-
mum of one year (consult the manufacturer before
starting if stored for longer).
NB! Always break current before working with the fan.
• Before service, maintenance or repair begins, the fan
must be tension free and the impeller must have
stopped.
• When cleaning and maintaining the fan always have
to be secured when open, so it can’t fall down and
cause injury.
• The fan must be cleaned when needed, at least once
per year to maintain the capacity and to avoid unba-
lance which may cause unnecessary damages on the
bearings.
• No special tools needed when cleaning.
• The fan bearings are maintenance-free and should
be renewed only when necessary.
• When cleaning the fan, high-pressure cleaning or
strong dissolvent must not be used. Cleaning should
be done without dislodging or damaging the impel-
ler.
• Notice the weight of the fan when closing after
inspection/cleaning. .
• Mount back all details in reverse order. Check that
the fan is closed and locked before starting.
• Make sure that there is no noise from the fan.
