(ISO 7183, Part 2) and therefore requires no further calibration.
S Do not exceed the machine's design limits, bypass excess air flow and check the
unit model and/or installation.
S For maximum performance from your dryer, follow the maintenance schedule de-
scribed in Chapter 4.
S The sound pressure level recorded for these dryers at 40 inch (1 metre) from the
