HPU and function. When ordering, specify that all hoses are flushed, filled with clean oil and capped at point of purchase. In most conditions, Harken recommends ISO 46 grade oil*. (See Oil Equivalent Table, pg. 15) If hoses are shipped, they may not contain oil. Harken can supply flushed, clean, empty hoses if ordered when purchased. -
Page 10: Configuration
Hydraulic Installation Port Indentification Hydro 1: HPU manifold contains four (4) valve ports, making valve port selection for a given function simple. HPU remote manifold attaches via hose to port on HPU. Remote manifold pressure port Attached manifold with 1 valve. Configuration The stock configuration of Hydro 1 is internally plumbed such that valves are pre-assigned to a manifold and motor. -
Page 11: Manifold Blanking Plates
Hydraulic Installation Manifold Blanking Plates All manifold stations must have either blanking plates or valves. Once all functions have been assigned, attach blanking plates to stations not in use. Tighten #10-24 bolts to 4.1 ft-lb (5.6 N-m) torque. The unit is shipped with the number of valves ordered. Additional valves may be added if blanking plates are present. -
Page 12: Electrical Installation
Electrical Installation Harken Hydro Units include 24 volt DC motors standard. 12 volt DC motors are available by special order. If a 12 volt DC motor was specified with system, refer to 12VDC motor electrical installation supplement for additional information. -
Page 13: Connect Deck Switches To Ecb
Electrical Installation Connect Deck Switches to the ECB Install the deck switches in a convenient location. By design, two (2) deck switches are used per function. Generally, one switch would actuate the function motor in a forward direction and the other in the reverse. Example: for a furler, the (A) switch would furl and the (B) would unfurl. -
