Circulation Through Gun Manifold - Graco Gusmer Reactor H-25 Operation

Circulation Through Gun
Manifold
Do not circulate fluid containing a blowing agent with-
out 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 No. 246362
