STEP 1 – Install system components
Install the SeaStar helm(s) and steering cylinder(s) according to the
installation instructions provided with the components.
Install the compensating line fitting to the helm as shown in section 3.2.
Install the SeaStar power assist pump as shown in section 3.3.

Make the electrical connections as shown in section 3.9, but do not
turn on the power assist yet.
NOTICE!
Do no run the P/A unit until the SeaStar steering system has been bled
free of air. Failure to do so may result in non-repairable damage to the
P/A unit.

3.2 Compensating line fitting
installation
The helm, power assist, and autopilot (if equipped) each have a small fluid
reservoir. The compensating line (also called a reservoir line or return line)
connects these reservoirs together so that they act as a single, larger reservoir.
This connection can be made with hose or with SeaStar nylon tubing.
The helm has two reservoir ports, marked 'R,' on the rear cover. These
ports are shipped plugged from the factory, so you will need to install a
fitting. An ORB fitting is supplied with the power assist for installation on
helms with a '-3' suffix in the part number. If you have an older helm with
NPT fittings you will need to order an NPT fitting kit, HF5540.
NOTICE!
Do not attempt to install an NPT fitting into a -3 helm hose fitting port.
Doing so will lead to irreparable damage to the helm. Only use SeaStar
ORB hose fittings.
