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.
