SEASTAR POWER PURGE JR
HA5445 POWER PURGING INSTRUCTIONS
NOTICE: Instructions shown below are for a single cylinder/single helm “manual” steering
system. For detailed instructions when using SeaStar Power Assist and/or Catamaran steering
systems, please refer to your Installation and Owner’s Manual
SINGLE CYLINDER - POWER PURGE OPERATION
Step 1. Connection
• Screw the quick coupling adapter into the helm filler port, and hand-tighten. See notes to the
side for dual helm application.
• Remove the blue hose from the Power Purge Box and connect both hoses to the quick
coupling adapter on the helm. Push the quick connects onto their male counterparts and
check to ensure they have locked in place.
• Remove the clear hose from the Power Purge Box and connect one end to each bleed fitting
on the hydraulic cylinder. Check to see if they have locked in place.
• Open both cylinder bleeders 1/2 - 1 turn.
• Attach the electric cable to the boat battery by connecting the black alligator clip to the
negative terminal and the red alligator clip to the positive terminal.
Step 2. Purging
• Turn the Power Purge Jr. ON. Oil should flow into and out of the helm. Wait twenty seconds
for the helm to fill with oil.
• Quickly turn the steering wheel clockwise until the cylinder rod is fully extended (you may
have to manually move the cylinder). Slowly continue to turn the wheel to hold the cylinder in
this position for approximately 30 seconds. Ensure there are no air bubbles escaping through
the cylinder hoses.
• Quickly turn the steering wheel counter-clockwise until the cylinder rod is fully extended on
the opposite side of the cylinder. Slowly continue to turn the wheel to hold the cylinder in this
position for approximately 30 seconds. Ensure there are no air bubbles escaping through the
cylinder hoses.
• Turn off the Power Purge Jr.
• Tighten both of the bleeders on the cylinder.
NOTICE
For dual helm applications,
install non-vent plug in upper
helm and perform procedure
described above on lower helm
first. Once complete, install
non-vent plug in lower helm
and repeat procedure with
upper helm.
CAUTION
Failure to install non-vent plugs
during this procedure will result
in oil leakage from other helm.
