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.
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.
