PCU Priming
If the instrument is to be primed for the first time after drainage for storage/transportation,
the following points apply:
1.
Remove PCU assembly — see Chapter 5, PCU Assembly.
2.
Remove filler plug.
3.
Using the filler bottle, fill the chamber through the top port until the fluid level
reaches the PCU O-ring. Allow time for the fluid level to stabilize.
4.
Continue this procedure until the fluid level reaches the bottom of the filler plug
port — DO NOT OVERFILL. If this occurs, wipe up any spills, and allow any
excess fluid to drain out of the port.
5.
Replace the filler plug.
6.
Replace the PCU assembly.
