0.5 L Hydraulic pump spec discrepancy

RE: 0.5 L Hydraulic pump spec discrepancy
OK Chuck. I was just following the purge procedure that was stated in the pump installation manual:

1. With the system in auto mode, press the -10 button ten times:
• the autopilot pump will try to drive the rudder to port.
• counter this rudder movement by turning the helm to starboard to keep the rudder
stationary.
• you will be able to feel any air in the helm pump: any air in this side of the pump will
rise to the helm pump and exhaust into the reservoir.
• continue until all of the air is out of this side of the pump.
2. Clear any air on the other side of the pump:
• press the +10 button ten times.
• the autopilot will try to drive the rudder to starboard.
• counter the rudder movement by turning the helm to port.
• continue until all of the air is out of this side of the pump.
• Repeat in both directions until both sides of the help pump are totally free of air.


While following this guide, I encountered the issue I described, where the drive still turned to port even though I told it to turn to starboard.

I was operating under the assumption that this process likely needed to be completed prior to running the dockside wizard. When I first fired up the P70R controller unit, it asked me the basic initial questions: Language and vessel type, but that was it, then the unit went to the main screen showing the heading.

Should I run the dockside wizard prior to trying to follow the pump purge instructions again?
