Do not circulate fluid containing a blowing agent without consulting with your material supplier regarding fluid temperature limits.
Circulating fluid through the gun manifold allows rapid preheating of hose.
1.Install gun fluid manifold (P) on Part 246362 accessory circulation kit (CK). Con- nect high pressure circulation lines (R) to circulation manifold.
