B Side Mix Manifold Restriction

B Side Mix Manifold Restriction

If the mix manifold (AB) is mounted on the machine, you do not need to adjust the restrictor (AJ). Leave open two turns minimum.

AJ

The B side restrictor (AJ) in the mix manifold is only used when the mix manifold is positioned remote from the machine with a short mix hose to the spray gun, or it has been adjusted as part of the ratio check procedure.

The B side restrictor (AJ) controls “lead/lag” ratio errors of the A and B flow into the static mixer tubes. These errors occur momentarily when the gun opens. The error is caused by differences in viscosity, volume, and hose expansion.

Adjust the restrictor stem (AJ) clockwise while spraying until you see a slight rise in the B side pressure gauge. The point where the pressure starts to rise is a good adjustment setting.

NOTE: Unless you are dispensing directly out of the mix manifold and mixer, this is an approximate adjustment.

See the mix manifold manual for more information.
