Flushing, Cleaning & Shutdown:
When finished with dispensing, it is necessary to flush and clean mixer and Dispense Head / Gun.
1. Open Dispensing Head / Gun momentarily to allow Putty pump shafts to run to full down position.
2. Close Dispensing Head / Gun valve all the way.
3. Position outlet of mixer into approved waste container
4. Properly Flush / Air purge the Mix Chamber and Mixer assembly.
5. Depending on the Mixer assembly installed we recommend at this point removing the Mix Chamber
and pushing out the mixer elements into a container for cleaning. An appropriate bottle brush should
be used for cleaning out the mixer housing and the mixer elements should be cleaned by hand (see
figures 44 & 45)
