Flushing
Procedure
1. Hold injection nozzle in waste container
2. Pull air purge button until excess resin is expelled.
3. Push solvent flush button. After approximately 30 seconds this button will reset. The
solvent flush button may be used a second time if necessary.
Note: If two or more injections are to be carried out consecutively, it may not be
necessary to flush the mixing head between shots. Approximately 1 minute after
the end of an injection, the whistle will sound indicating that the machine must be
flushed. Operating the solvent flush or continuing with the injection will cancel the
alarm.
Injection & Flushing when using an Autosprue™
When carrying out an injection through an Autosprue™, it is essential that the both the
Autosprue™ resin and signal pipes are connected to the injection head before starting
injection. The Autosprue™ MUST REMAIN CONNECTED to the injection head for the
flushing cycle. Only when flushing is complete may the Autosprue™ be disconnected.
Refer to Autosprue™ instructions for further details.
