POWER PURGE FILLING AND
PURGING THE SYSTEM
If system is plumbed as shown in Config. B (page 7), C (page 8) or D
(page 8), please contact Teleflex Marine for specific bleeding details.
BEFORE bleeding the main steering system (helm, hoses and
cylinders), the RETURN line will need to be purged.
Removing Air from Return Line
• Install the helm adapter into the helm pump and attach the helm
hose from the power purge unit.
• Connect one of the fluid return hoses (cylinder lines) from the
Power Purge unit to the Reservoir bleed fitting on the P/A unit.
(see figure 10 on page 16 for bleed fitting location).
• Open reservoir bleed fitting 1 turn.
DO NOT OPEN MANUAL BLEED VALVE WHEN USING A POWER PURGER
• Turn ON the Power Purge unit and continue to run until NO air is
visible leaving the P/A unit.
• Turn OFF Power Purge unit.
•
Close reservoir bleed fitting and continue on with the following steps.
• Ensure the reservoir bleed fitting is closed then remove the hose
from the reservoir bleed fitting and connect to the steering cylinder
bleeder fittings. Ensure the quick connect is locked onto the fitting.
• Open ALL Cylinder bleed fittings 1-1/2 turn.
DO NOT OPEN MANUAL BLEED VALVE WHEN USING POWER
PURGE UNITS.
• Turn Power Purge unit ON.
• Oil should flow into and out of the helm pump. Wait twenty
seconds for the helm to fill with oil.
• Turn the steering wheel clockwise until the cylinder rod is fully
extended (you may have to manually push the cylinder rod).
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 the steering wheel counter-clockwise until the cylinder rod is
fully extended (you may have to manually push the cylinder rod).
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 Power Purge unit
• Tighten ALL bleed fittings on the steering cylinder(s)
• Repeat above steps with the Power Assist unit ON.
Continue on with Oil Level and System Check on page 20.
