Setting Catalyst Percentage


Megaject catalyst levels can be adjusted in the range 0.5% to 4.5% to suit differing resin
systems. This is achieved by movement of the catalyst slave pump along ratio arms directly
connected to the main resin pump.


Safety Note: Before altering catalyst percentage ensure that the resin and catalyst

recirculation valves are in the recirculation position. REMOVE air/power supply to the
machine. Any guards removed MUST be replaced before operation.

Procedure

1. Remove front guard where applicable


2. Remove ratio locking pins from the top and bottom joints of the catalyst slave

pump to the ratio arms by depressing the top of the pin, and then withdrawing.


3. Set catalyst slave pump to new required percentage on ratio arms and replace

top and bottom ratio locking pins.

4. Recirculate machine to ensure pump is correctly primed

5. If required, carry out a timed gel test, injecting approx 200 cc’s of resin into a

cup.
