The relief pressure and 53 flow capacity of the relief device must satisfy system requirements. The accuracy of the indication of pressure gauges can 52 change, both during shipment (despite care in packaging) and during the service life. If a pressure gauge is to be used with these products and if inaccurate indications may 18 24 21 be hazardous to personnel or property, the gauge should be 29 calibrated before initial installation and at regular intervals during use. 28 Before using these products with fluids other than air, for non industrial applications, or for life-support systems 23 consult Norgren. 17 26 27 20 19 25 22 36A 31 34 37 30 38 36 36C 33 32 36B 35 45A 40 43 45C 39 45 50 51 49 48 47 42 41 46 45B 44 Norgren 2000 (2/00) IM-160.300.02 a subsidiary of IMI plc Supersedes 7/98
