LEGEND® II INSTALLATION MANUAL
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.
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.
Patents Pending
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.
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.
