10 Hydro 2
Port Indentification
Hydro 2: HPU has two (2) manifolds containing four (4) valve ports each. HPU remote manifold attaches via hose to pressure ports on
distribution manifold.
Hydraulic Installation
Configuration
The stock configuration of Hydro 2 is internally plumbed such that valves are pre-assigned to a manifold and motor. This is illustrated
in the Function Assignment Table. Hydro 2 unit uses valves 1-4 with manifold 1 and motor 1. Valves 6-9 are used with manifold 2 and motor 2.
Valve Station 5 (Double flow valve) is located on the distribution manifold and is used with motors 1 and 2.
Function Assignment
The Hydro 2 unit is equipped with two manifolds either attached or remote per design specification. Each manifold style has four (4)
valve stations corresponding with four (4) ECB switches. Assign each function to its own set of valve ports. When assigning valves to
functions, be sure to separate functions that will run simultaneously to different manifolds.
Example 1: Run primary winches on different manifold than mainsheet.
Example 2: Run primary winches on different manifold than headsail furler.
Record the function name in the Function Assignment Table below. Refer to this information when connecting the electric switches.
For easy reference, label the hydraulic hoses in accordance with the valve. For example: label Valve Station 1 hoses for your attached
manifold "VS1A and VS1B".
