Riskofinjuryposedbyburstingpartsintheeventthattheyaresubjectedtopressurein
thewrongdirection
Thedevicehasbeendesignedforaspecificdirectionofflow,whichislabeledonthedevice.
Subjectingthedevicetopressureinthewrongdirectionmayresultinseriousinjurycaused
byburstingparts.
 Pressurizethesystemonlyontheinletside.
