6.0 MAINTENANCE

IMPORTANT

Isolation - Before commencing work make sure that the unit and 

Nuaire control are electrically isolated from the mains supply.

Ensure that all mechanical and electrical connections and fixings are 
secure and that inlet and outlet ductwork is free of any obstruction or 
debris.

Briefly switch the fan on/off to ascertain correct direction of impeller 
rotation, compare with the rotational label fitted and correct if 
necessary.

Complete the test by running the fan for approximately 15 minutes, 
taking and comparing voltage, full load and starting currents with the 
fan rating label. Monitor flexible connections to ensure no leakage and 
AV mounts for correct alignment.

It is important that maintenance checks are recorded and that the 
schedule is always adhered to, in all cases, the previous report should 
be referred to.

6.1 Routine Maintenance

Clean all areas of unit and treat any areas of corrosion.

Check all access doors for leakage and if necessary locks should be 
adjusted and any replacement gasket materials should be replaced 
as required. 

Check that safety grilles are secure and free of obstruction.

6.2 Semi-Annually 

Thoroughly inspect the unit and its components for corrosion, 
acting immediately to treat/restore any damaged areas. 

All electrical terminals within the unit should be tightened. 

Check all earth connections. 

Check resilient mounts (where applicable) and replace any that 
have any wear or deterioration.

Check motor for undue wear, signs of overheating and apply 
winding insulation and continuity tests.

6.3 Lubrication

Motors are fitted with sealed for life bearings and do not require any 
lubrication.

6.4 Motor Repair

Due to unit certification EN12101-3 and in compliance with the 
construction products directive, the motor must be returned to the  
motor manufacturer for replacement.
