F. Checking Operation
When operating correctly, the Legend
a random pattern throughout the pool, vacuuming
and sweeping the bottom. The climbing ability of the

Legend is dependent on the pools structure and
water flow coming into the pool. It will perform more
efficiently in pools without sharp angles or curves in
the transition from the floor of the pool to the wall.

2. Sweep Hose Adjustment

The Sweep Hose operates in a gentle sweeping
motion. To increase or decrease the motion of the
Sweep Hose, adjust the screw which is located on
the Feed Mast Barb below the Ballast Float. Turning
the screw clockwise will decrease the motion and
