COMMISSIONING
General
The initial commissioning and testing of your AirBench has been performed prior to delivery. However, as part
of in-house commissioning we recommend that you complete the following tasks and record the results as
appropriate in the system logbook.
In House Commissioning
The following tasks should be completed by a responsible person; for example, the Health and Safety Officer,
or Director, responsible for this process.
-
Review the commissioning certificate for this unit, in particular any notes made by our engineer in relation to
use.
-
Ensure all operators are trained to use this machine and are aware of the effective capture zone in which
they should aim to work.
-
Ensure all operators are aware of the filter maintenance routine required for this machine.
Once complete, you should note this on the commissioning certificate and retain the certificate for future
reference.
As operating conditions vary, each installation will vary in maintenance needs and this is best established by
empirical means, regularly checking filter condition in the first weeks of operation to establish a procedure.
Reduced airflow is a key indication of filter condition. If the filter pressure gauge on the front of the unit is
showing in the red zone, this indicates low airflow and filters should be checked and cleaned or changed
promptly, according to the instructions contained within this manual.
We recommend keeping the commissioning certificate, Quick Start guide, and logbook with the machine at all
times for operator access.
If in doubt please contact the manufacturer quoting the machine serial number.
Fume Extraction Units
The effectiveness of carbon filtration improves as airspeed is lowered allowing fumes to spend longer passing
through the filters. A speed controller is supplied with carbon filtered units to allow airflow to be adjusted to the
optimum level.
We therefore recommend adjusting the speed controller provided to the lowest level at which extraction is still
effective and marking this operation point on the speed controller. Ongoing adjustment may be required as
filters become blocked with use.
