contain high pressure air. keep face and other body parts away from
outlet of drain. Use aNsI Z87.1 eye protection (caN/csa Z94.3)
when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use ear protection [(aNsI s12.6
(s3.19) hearing protection] as air flow noise is loud when draining.
note: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers,

contain oil and rust which can cause stains.
6. After the water has been drained, close the drain valve. The air
