Overview

The left side of the mix manifold is intended for the major volume material, or the higher viscosity material if using a 1:1 volume mix. This side is referred to throughout the manual as the resin side or “A” side.

The right side is referred to as the Hardener side or “B” side. The “B” side incorporates an adjustable restrictor for balancing the system back pressure and flow.

See FIG. 2 to view flow of “A” and “B” material inside the Mix Manifold.

The resin and hardener enter the mix manifold through the manifold inlet ports and spring loaded carbide ball checks. The “A” material flows through the manifold to the material outlet port. The injector tube creates a hollow stream of “A” material for the “B” material to fill once the hardener exits the injector tube. The resin and hardener material mix after they have left the mix manifold block (B).

When the manifold is mounted remote from the propor- tioner, adjust the “B” side restrictor (F) to balance the sys- tem back pressure and flow.

On the standard mix manifold, mixed material is flushed out by sending a flush solvent through the B side center tube. On the quickset mix manifold, solvent is also flushed across the A side fluid check valve.
