•
With the cluster raised 1 meter (~3feet) off the ground, lower the rear motor hoist only. The array
will swing slowly forwards until the centre of gravity lies directly below the front motor hoist.
Continue to lower the rear motor hoist and the rear articulated part of the Kelping Beam will swing
downwards towards the cabinets. Stop the hoist when the rear arm of the Kelping Beam reaches
an elevation of approximately –70 degrees. The angle is approximate and is not critical to the
final angle of the array.
IMPORTANT
When lowering rear motor hoist, the cluster swings forward: ensure there is no obstacle
in front of the cluster within sufficient distance
•
Attach the lower hook of the Kelping Chain Link to the rear of the Bottom Bumper using a 3/4
Shackle.
•
Manually raise the Bottom Bumper until it is approximately parallel with the ground and set the
adjustable clutch in the Kelping Chain Link so that the chain is taught.
•
Make a final check that the Kelping Link Chain is correctly installed and store the surplus chain in
the chain bag supplied. The chain bag should be clipped to the clutch adjuster assembly.
•
The rear motor hoist may now be raised to apply the pull-up force to the bottom of the array.
Notice that, as the rear hoist is raised, the cabinets in the array close together to the angles set
by the linking bar adjustments.
•
When all of the cabinets are closed together the array begins to move as a whole. This is the
indication that the angles have been correctly set. Ensure that the rear arm and the main
member of the Kelping Beam remain at an angle of ~20° with respect to each other, indicating
that the pull-up force will remain constantly applied.
IMPORTANT
DO NOT attempt to make any changes to the linking bars when the rear pull-up force is
applied.
