NOTE: It is recommended to make notes of all settings during ratio checks
including pump pressures and material temperatures. At the start of each work
week, a ratio check should be performed. This is even more important when
using fillers mixed into the Poly resin to assure filler settling has not taken place
in the Poly resin filter and or pump.
Dispensing Material:
4. Install mix chamber, spring and ball checks. It is sometimes easier to install mix
block first then remove the plugs on the of the front mix block to install the ball
and springs (see drawing CPD-6100 if needed). Attach the static mixer to mix
chamber.
5. Pull the trigger on the Gun; dispense material into a waste bucket. Make note of
the fluid pressures for both A & B materials then release the trigger on the gun
and flush the gun and mixer out. The fluid pressures do not have to match but it
is preferred that there is not a huge difference - 300 psi on the resin (A) and 150
psi on the hardener (B) would be acceptable in most cases. In some cases, the
pump may run so slow that it is difficult to read an exact pressure. As long as
both pressure gauge needles come off of their stops is all that is needed for
proper ball seating when gravity feeding.
