IMPORTANT
Before attempting to carry out any work on our units, the unit
MUST BE COMPLETELY ISOLATED
from its electrical supply.
Ensure a minimum of two minutes after electrical
disconnection before commencing work. This will allow any
moving part to come to a rest, all accompanying
documentation including warning labels on the unit must be
referenced
WARNING
When used in conjunction wih an Inverter for speed control, a
minimum of 5 minutes should be given to allow for the
capacitors to discharge before starting work
Care should also be taken whilst cleaning the unit in the
event that wind or air movement should cause the fan to
freewheel.
Annual checks
Check inside the unit for an accumulation of dust, grease
etc. If the fan impeller is heavily soiled, clean out carefully
(ensure the unit is properly isolated). Failure to do this
periodically could lead to a loss of performance or the fan to
become out of balance, leading to bearing failure. Check the
drainage holes (cowl unit only) are clear of debris and
service as required. Clean the external louvre/cowl to ensure
that performance is maintained. Inspect the backdraught
shutters for signs of damage (cracks or bending).
IMPORTANT
When removing the louvre/cowl please note that these
fixings secure the units into position and by removing these
the unit may be released from the wall. This is particularly
important with the cowl unit as the backdraught plate would
be unsupported.
PLEASE ENSURE THAT THIS DOCUMENT IS
