B Side Mix Manifold Restriction - Graco XP35 Instructions Manual

B Side Mix Manifold Restriction

B Side Mix Manifold Restriction
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.
The restrictor is used primarily when the mix manifold is
positioned remote from the machine with a short mix
hose to the spray gun. It can also be used in the ratio
check procedure.
AJ
AB
If the mix manifold (AB) is mounted on the machine, you
do not need to adjust the restrictor. Leave open two
turns minimum.
To Adjust the Restrictor:
Adjust the restrictor stem 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 adjust-
ment 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.
