Set up the equipment as it would be used on the actual enclosure at the commencement of the job.

Take actual pressure gauge readings in normal use with clean filters and any ducting fitted, by means of

observation, measurement and judgement determine when the pre filters require changing and record the

gauge reading at this point.

This information will enable any future changes to be related to the actual observed pressure gauge readings.
