TABLE 4: Panel P urge Flow Troub lesh oo tin g - Work Thro ugh Table as Necessary Until
There Are Correct Flow Char acteristics
Is there enough fluid in the test cart ? Add fl uid to the test cart as nec es s ary
Wipe leading edge with paper towel to even
out the fl uid flow
If flow still uneven, use an approved
proced ure to clean the dry spo ts
Are there correct flow characte ristics f or the
porous panel? If no,
Do the panel pu rge again
Does the fluid leave the test cart c orrec t ly?
If no,
