Filling And Purging The System
NOTE: Due to system design, one technician may not be able to completely purge all the
air from the system after installation. This will result in spongy and unresponsive steering.
Two technicians are required for successful filling and purging of any system.
Twin Station and/or Twin Cylinder
WARNING
Avoid serious injury or death resulting from a loss of steering control. Improper
venting or plugging of hydraulic helm pump reservoir can cause loss of fluid or
introduction of air into hydraulic system resulting in insufficient hydraulic pump
pressure for proper steering control. If more than one steering station is being
installed, the vent-fill plug on all but the uppermost helm must be replaced with a
non-vent plug which is included in a dual station fitting kit.
For Twin Station and/or Twin Cylinder filling and purging (bleed) instructions, follow instruc-
tions provided by SeaStar. How to fill and purge a Single Station with Single Cylinder Sys-
tem is outlined in the following.
