8. MAINTENANCE
8.1 Cleaning
The SAS SUPER IAQ does not require special care and maintenance procedures. Clean the
outside surface with a normal mild NON CORROSIVE detergent.
Do not subject the air sampler to sudden shock.
Clean the air sampler with a soft damp cloth and a mild detergent. Do not use harsh
abrasives.
Do not submerge in water; do not pour or spray water directly on the air sampler.
Do not use acetone or other volatile solvents for cleaning.
8.2 Validation and Calibration
The motor speed and consequently the air flow are related to the electrical power supply, motor
bearing conditions, etc. It is therefore suggested that the unit should be validated at least every
six/twelve months.
The validation of the air flow rate should be done by a certified anemometer in a wind tunnel.
This type of certification may be performed by PBI international or an official PBI distributor.
NOTE
: The “Pyramid” is to be used for internal validation only (i.e. to verify the correct
working conditions of the air sampler). When an Official Calibration is requested, a certified
anemometer must be used to meet the required traceability characteristics (i.e. FDA inspections
require a Calibration Certificate that is traceable to know standard such as the NIST
8.3 Performance routine monitoring
The SAS SUPER IAQ should be checked monthly / bimonthly (depending how often they are
used) using the “Pitot Kit” or “Propeller” units to monitor that they are working correctly and
their performances has not been affected by bad handling or damage. (
