Throughout this publication Warnings and Cautions (accompanied

by the International Hazard Symbol ) are used to alert the

manufacturer or installer to special instructions concerning a

particular service or operation that may be hazardous if performed

incorrectly or carelessly.

Observe Them Carefully!

These “safety alerts” alone cannot eliminate the hazards that they

signal. Strict compliance to these special instructions when performing

the installation and maintenance plus “common sense” operation

are major accident prevention measures.

Not ce to Boat Manufacturer

or Installer

Hazards or unsafe

practices which

COULD result in

minor injury or

product or property

damage.

CAUTION

Hazards or unsafe

practices which

COULD result in

severe personal

injury or death.

WARNING

Immediate hazards

which WILL result in

severe personal

injury or death.

DANGER

Information which is

important to proper

installation or

maintenance, but is

not hazard-related.

NOTICE

Cleaning fluids containing ammonia, acids or any other corrosive

ingredients MUST NOT be used for cleaning any part of this

Hydraulic Steering System. Failure to comply will cause serious

damage to the steering system, resulting in possible loss of

steering, causing property damage, personal injury and/or death.

WARNING

Help protect your boating environment by ensuring that all used oil

is disposed of properly.

NOTICE

Don't compromise performance... use genuine

SeaStar parts only!

• SeaStar helms • SeaStar Cylinders

• SeaStar hoses • SeaStar Oil

Substituting non SeaStar parts in any part of the SeaStar hydraulic

steering system may seriously compromise system performance.

Before proceeding with the installation please read these instructions

thoroughly to familiarize yourself with the workings of this SeaStar DC

Power Steering System. SeaStar Solutions cannot accept responsibility

for installations where instructions have not been followed where

substitute parts have been used or where modifications have been

made to our products. Warranty may be void if products other than

SeaStar Solutions products are used with this system.

DC Power Steering System

The SeaStar DC Power Unit is a self contained steering system

designed to provide an alternative to existing power steering

systems. Unlike conventional power steering systems which require

engine/pulley driven pumps oil coolers oil reservoir filter and

relief control valves the DC Power Unit is an integrated power

steering solution requiring only the DC Power Unit a steering

cylinder and one or multiple helm pumps. The end result will be

less power consumption and very little heat generation. Installation

of the SeaStar DC Power Unit requires fewer parts less installation

time and easy troubleshooting making it an all around user friendly

system. With the built in semi-automated purge system the

SeaStar DC Power Unit will help the installer bleed ALL of the air

out of the steering system in minimal time.

The DC Power unit incorporates an autopilot pump as well for a

cleaner more reliable installation than using external pumps.

SeaStar DC Power Unit Compatibility

DO NOT use extruded nylon tubing for plumbing this system. ONLY use

SeaStar Outboard type steering lines for all helm pump connection

and ONLY use Dash - , 2000psi hose for PRS/TNK connections.

3/ " Copper tubing is also acceptable as a substitution for SeaStar

lines, provided 4' SeaStar hose sections are used to connect the

copper to any fittings.

Failure to follow the above may lead to loss of steering control

causing property damage and/or personal injury or death.

WARNING

Never use Brake Fluid. Any non-approved fluid may cause irreparable

damage, loss of steering, and cancellation of warranty.

In cases of extreme emergency any non-toxic non-flammable fluid

may provide temporary steering.

CAUTION

The DC Power Unit is compatible with the following SeaStar

steering equipment:

All 1.4 and 1.7 SeaStar Non-Feedback helms. DC Power Unit is NOT

compatible with Hynautic Capilano or other manufacturers’ helms.

1.4 Relief Module Installation

• Remove steering cylinder from its packaging and inspect servo

valve block. The cylinder MUST have three tapped holes on the

face of the servo valve block as shown in figure 5 below. If the

servo valve block does NOT have these tapped holes contact

SeaStar Solutions Technical Support.

• Remove fittings from the PRS and TNK ports on the steering

cylinder servo block if required.

• Inspect valve block face. It MUST be free of ALL contaminants

including thread sealant debris burrs gouges or large

scratches. Clean as required.

• Install both quad rings (items #2) into relief valve module as

shown in Figure 5.

• Insert three (3) socket head cap screws (items #1) into relief

valve module (item #3) and fasten to front face of cylinder servo

valve as shown in Figure 5. Torque mounting bolts to 40 in.lb.

• Clean threads and apply a Teflon based liquid pipe sealant to the

threads of the fittings that were removed in the second point

above. Install fittings into the ports on the relief module. DO NOT

USE TEFLON TAPE. Torque fittings to 200 in. lb.

WARNING

Ensure that the quad rings

remain seated in the relief

valve module and are not

pinched and/or rolled between

the module block and the

servo cylinder valve. Failure do

so will result in fluid leaks

causing property damage,

personal injury and/or death.

NOTICE

All cylinders manufactured

during or after January 2008

will have mounting provisions

for the relief module.
