7. If MPG system is fitted, adjust preset regulator until preset level gauge reads 2 bar.
8. Ensure both resin and catalyst recirculation valves are in the recirculation position. Turn
recirculation switch ‘on’. Recirculate until a bubble free fluid flow is observed at both the
resin and catalyst containers and pump output is even on both strokes. If air in the
catalyst system persists turn the recirculation switch ‘off’ and repeat procedure 6
Note: The recirculation switch should be used for recirculation only and must be turned ‘off’
when priming is complete.
9. Turn resin and catalyst recirculation valves to inject position.
10. Using either the start button (Predetermined counter machines only) or the thumb start
switch, pump 300cc’s (3 counts) into a waste container.
11. Pump 200 cc’s (2 counts) into a cup. DO NOT STIR.
12. The injection head must be flushed. Return resin and catalyst recirculation valves to
recirculate position. Place injection nozzle in a waste container. Operate the air purge
button to expel waste resin. Press the solvent flush button. This will reset after
approximately 30 seconds. Operate the air purge button to dry out the head and mixer
tube.
13. Check that resin in cup gels evenly and fully. If not, return to procedure 6.
Note: We strongly recommend that after injection, the recirculation valves are always
placed back into the recirculation position. This ensures that small amounts of resin and/or
catalyst do not leak forward into the head chambers. Major movement of the pipes and/or
day and night workshop temperature variations could cause slight weeping into the head if
the machine is idle and the recirculation valves are not left in the recirculation position.
