Coupling Block

Chemical hoses are joined to gun block by a
coupling block to ease installation and removal
of gun.
Manual Valves
Two manual valves located on coupling block
control flow of each chemical component to
gun.
Triggering gun with manual valves closed
may cause crossover if any residual
chemical remains in gun ports.
Never open manual valve unless coupling
block is secured to gun or unless you point
gun into waste container.
Open Manual Valves
Use 5/16 in. nut driver to turn manual valve
clockwise approximately three full turns.
