3. Reassemble observing order illustrated in dwg. 82012_01. Ensure Bodies (1032)
and (1035) are correctly screwed together using PTFE tape or similar thread
sealant.
4. Re-attach valve to pump using thread sealant.
5. Re-prime catalyst / hardener system to remove any air from the system.
Flush:
Press the flush button to clean the injection head. The operator cannot initiate a flush
when the machine is in injection mode, therefore accidental flushing of the system into a
mould during an injection is not possible.
The flush system has an automatic timer function that will stop the flush cycle
automatically. The default duration of the flush is set between 30-60 seconds during
manufacture; however this can be adjusted by the user if required.
The flush cycle can be stopped at any time by pressing the Stop button.
NOTE: Before the flush button is pressed, ensure that the outlet from the mixing
head is directed to a suitable waste container.
Flush timer adjustment:
The flush timer duration can be increased or decreased by adjusting the flush timer
restrictor. This controls the rate of airflow out of the timer circuit reservoir, and the speed
that the pressure falls in order to actuate the automatic flush stop valve.
To set the timer, simply adjust the restrictor and then time the flush cycle. Continue this
procedure until the desired flush time is obtained. Times of over 60 seconds are
achievable with this circuit.
NOTE: If the restrictor is fully wound in, air flow will be blocked and the timer will not
operate.
