Pentair Legend II Fine Tuning the Legend, Thrust Jet Adjustment, Checking Wheel RPM

H. Fine Tuning the Legend® II

1. Thrust Jet Adjustment

There are two Thrust Jets located in the back of the Legend® II. These Thrust Jets alter the direction of the cleaner. The factory standard position for the jets is set slightly to the right. (See illustration below.)

In certain pools, altering the thrust jets can increase performance of the Legend® II. Moving the thrust jets up can increase climbing, and moving them down can decrease climbing. Moving the thrust jets to the left pushes the unit left and moving them to the right pushes the unit right.

3. Checking Wheel RPM

To determine whether the Legend® II is receiving the proper water pressure, turn off the pool pump, and carefully remove the Legend® II from the pool.

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 located on the Swivel Mast Barb below the Ballast Float. Turning the screw clockwise will decrease the motion and counter clockwise to increase the motion of the Sweep Hose.

Mark the front drive Tire/Wheel with a marker, or use the Logo located on the side of tire as a marker to count the rotations of the wheel per minute.

Have someone turn on pool pump while you place the Legend® II in the pool just beneath the water surface. (Be sure to hold onto the Sweep Hose to avoid getting wet.)

Count the rotations of the marked wheel for exactly one minute. (Be sure the Back-Up Valve isn't cycling at this time.) The rotations will give you the Revolutions Per Minute, (RPM).

For proper performance, the Legend® II operates between 25-32 RPM. If the RPM is below 25 then closely follow the instructions on the next page.
