Installation Considerations

 

 

 

 

 

 

 

 

• The pump must be reconfigured if the boat is

 

 

 

 

 

equipped with an unbalanced steering cylinder

 

 

 

 

 

(page 3).

 

 

 

 

• The pump should be mounted the pump

 

 

 

 

 

horizontally if possible.

 

 

 

 

• If the pump must be mounted vertically, mount

 

 

 

 

 

it with the hydraulic connections facing upward.

 

 

 

• Removal of the power assist module may be

 

 

 

 

necessary to gain access to the fittings, hoses,

 

 

 

 

 

and bleed-tee fitting.

 

 

 

 

• The pump must be installed between the

 

 

 

 

 

cylinder and the power assist module.

 

 

• Garmin recommends using the t-connector

 

 

 

method to connect the hydraulic lines to the

 

 

 

 

 

 

 

 

 

 

pump. See the diagram page 8 to view the

 

 

 

 

 

alternate connection method.

 

 

 

• To allow for easy pump disabling and removal,

 

 

 

 

Garmin recommends installing shut-off valves

in the hydraulic lines between the pump manifold and t-connectors.
