This document is intended to give details and guidance for a boat builder or equipment installer to properly install the Seakeeper 1 (applicable to serial numbers 1-233-0631 to current).

Reference Documents:

• 90510 – Seakeeper 1 Hardware Scope of Supply
• 90513 – Seakeeper 1 Packing List

Precautions

1. The Seakeeper must only be lifted from the supplied lifting eyes (see Section: Transport and Unpacking).
2. Precision bearings support the Seakeeper flywheel. While unpacking and lifting the Seakeeper assembly, DO NOT drop or impart mechanical shock, as this could damage the bearings.
3. While handling or installing the Seakeeper assembly, protect exposed hydraulic brake cylinder rods (see Figure 1) from scratches or damage, as this could lead to premature seal failure and oil leaks.
4. Exercise care to protect any exposed surfaces, as damage to the finish could lead to the Seakeeper‘s early appearance degradation.

Safety

There is a large torque about the gimbal axis when the Seakeeper is precessing. Seakeeper cover panels are provided to prevent personnel or equipment from contacting the Seakeeper while it is in operation. These covers should not be stepped on or have anything placed on top. The covers should always be in place during operation.

_________________________________________________________________________________________

If it is ever necessary to access the Seakeeper while the flywheel is spinning, the Seakeeper must be locked at the display to stop the Seakeeper from precessing.

_________________________________________________________________________________________

Stand clear of the Seakeeper and all moving components during operation.

_________________________________________________________________________________________

Unit may be started remotely. Assume it could move without warning.

_________________________________________________________________________________________

The following must be true before accessing the Seakeeper:
• Input power must be disconnected for at least 10 minutes
• Seakeeper must be locked
• Flywheel must be at zero speed
