Installation and Maintenance
Maintenance (General)
Isolation - Before commencing work make sure
that the unit, switched live and Nuaire control are
electrically isolated from the mains supply.
Maintenance Intervals
The first maintenance should be carried out three months after
commissioning and thereafter at twelve monthly intervals.
These intervals may need to be shortened if the unit is operating
in adverse environmental conditions, or in heavily polluted air.
NOTE: Failure to maintain the unit as recommended will
invalidate the warranty.
Lubrication
Motors are fitted with sealed for life bearings and therefore
require no further lubrication.
General Cleaning and Inspection
Clean and inspect the exterior of the fan unit and associated
controls etc. Remove the access panel from the fan unit. Inspect
and, if necessary, clean the fan and motor assemblies and the
interior of the case. If the unit is heavily soiled it may be more
convenient to remove the fan / motor assemblies.
Check that the shutters are free to move smoothly and that
they seal the appropriate fan outlet effectively.
Clean and inspect each fan and motor assembly as follows;
taking care not to damage, distort or disturb the balance of
the impeller.
a) Lightly brush away dirt and dust, paying particular
attention to any build up at the motor ventilating slots.
If necessary, carefully remove with a blade or scraper.
b) Stubborn dirt at the impeller may be carefully removed
with a stiff nylon brush.
c) Check all parts for security and general condition.
Check that the impeller rotates freely.
Refit the assemblies to the unit (see Replacement of Parts)
then replace the access cover.
If Nuaire controls and or remote indicators are fitted, remove
the cover and carefully clean out the interiors as necessary.
Check for damage.
Check security of components. Refit the access cover.

Replacement of Parts

The only item of the fan units unit likely to require replacement
are the fan/motor assemblies due to a failed motor or damaged
impeller. In either eventuality the complete fan/ motor assembly
must be removed from the unit case.
Remove the access cover. Disconnect the incoming wiring from
the connection box (located on the fan scroll) on the particular
fan/motor assembly to be removed. Support the weight of the
fan/motor assembly and remove the mounting screws and
washers. Lift the assembly out of the case.
After replacing the faulty item, refit the fan/motor assembly
and re-connect the incoming wiring to the fan mounted
connection box. Replace the access cover.
