Clean the Spray Chamber and Injector Holder
1 Clean the spray chamber and injector holder by wiping with a Kimwipe moistened with
isopropanol to remove any residue.
2 Inspect the O-rings on the injector holder for damage or discoloration. Replace the
O-rings if necessary. Use the O-ring removal tool to remove the damaged O-rings.
Clean the Vacuum Interface Cones
WARNING Before performing maintenance on the cones, switch off the RFG
power using the red circuit breaker at the right-side panel of the system. Wait at
least 5 min for residual electrical charge to dissipate.
CAUTION Hot surface hazard. The torch components, the vacuum interface, and
the heater assembly components remain hot for some time after the plasma has
been shut off. Allow sufficient time, at least 20 min, for these items to cool to room
temperature before you handle them.
