points and place them in a prominent position near the instrument.
DO
... ensure the air supply is always very clean at a stable pressure. A coarse filter and desiccant dryer system
and double filter regulator assembly should be used.

bowls whenever necessary. (See Chapter 5.)

necessary.

moved or when the air is switched off.
... refit the air connector plug supplied with the instrument whenever the air line is disconnected.
... disconnect and blast air through the air line whenever starting up after any period which air has been
switched off. (Not necessary every morning, unless you know your air supply tends to accumulate water
