4.2 Manual fill and purge

You will need two people to thoroughly fill and purge the system. One
person may not be able to remove all the air from the system, resulting in
spongy and unresponsive steering.
NOTE
Ensure fluid is always visible in the helm fill tube when purging. If the fluid
level disappears into the pump air may be drawn into the system, which
will increase filling time.
4.2.1

Hydraulic fluid requirements

You will need two bottles of fluid (HA5430) for a single station, single
cylinder system. You will need an additional bottle for each helm, cylinder,
or autopilot added to the base system.
NOTE
If installing a PA1200-2HP pump, you must use SeaStar EPS steering fluid
(HA5483) to get the full performance of the pump.
You will need a clean container to collect the fluid during the purge process.
The fluid you collect can be re-used if filtered through a fine mesh screen.
NOTICE!
Protect your boating environment by ensuring that all used fluid is
disposed of properly.
