Re-priming:
To be carried out when the operator changes the resin / catalyst in a machine that has
already been commissioned.
1. Remove pickup wand(s) and filter from fluid and place in a clean empty container. Then
recirculate machine to empty the fluid lines.
2. To clean the lines and pump, place pick-up pipe in solvent container and re-circulate
until clean solvent is observed at the recirculation pipe.
3. Place the recirculation pipe into a waste container. Place pickup wand in new fluid.
Recirculate machine until all solvent is discharged and new fluid is observed at the
recirculation pipe.
4. Place recirculation pipe in fluid container with pickup wand.
5. Continue recirculating until pumped material is free of all air bubbles.
Note: If the new material is of a similar chemical type to the existing material, then
it may not be necessary to clean the system with solvent before loading the new
material.
Injecting:
This procedure should be followed each time an injection, or series of injections are
carried out.
Before Injection:
1. Check the incoming air pressure gauge reads at least 6 bar (87psi).
2. Push the Stop Button to stop the recirculation.
3. Ensure there is sufficient resin, catalyst and solvent to complete the Injection cycle.
4. Check secondary pump is set to required ratio.
5. Adjust the pump pressure regulator to the required setting. (Suggested initial setting
of – 1 bar (15psi))
6. Adjust the MPG pre-set regulator until the required maximum injection pressure is
indicated on the MPG preset level gauge. (Suggested initial setting
– 2 bar (29psi))
7. Set pre-determined count to required count number. Press counter reset button to
set output count to zero.
