3.2.2 Setting Dirty Filter Switch Pressure

Nuaire recommend the pressure switch be set to trigger when the 
filters experience a 125 Pa increase above the clean filter resistance for 
the largest commissioned airflow rate. Use the adjustment dial to set 
the pressure at which the switch will trip. When the pressure falls below 
this set value, the switch returns to its resting position.

4.0 MAINTENANCE

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.

4.1 Carbon Filter Maintenance

After a period of time, activated carbon in filter cells will become 
saturated by odour, gas and chemical vapour contaminants and will 
require replacement in order to maintain the filtration efficiency of the 
carbon filter. HIAQM Carbon Filters have a lifespan of 2 years under 
normal conditions. However, under certain circumstances, such as 
highly polluted air, carbon filters may need to be replaced on a more 
frequent basis. Contact Nuaire for accurate assessments of carbon filter 
lifespans.

4.2 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. 

4.3 Every 3 Months 

Check filters and change/clean if required, failure to do so may 
impair the performance and energy efficiency of this unit.

4.4 Annually 

Thoroughly inspect the unit and its components for corrosion, 

acting immediately to treat/restore any damaged areas. 

4.5 Replacement Filters

To check the filter type within a unit refer to the module product label. 
Replacement filters can be purchased direct from Nuaire using the 
below code format.
