3 Introduction
English
The following are important facts to remember before installing and operating the Legend ®.
1. Always disconnect the Legend®from the pool wall when cleaning or back washing the pool filter.
2. After cleaning or back washing, let the filtration system run for at least five minutes before reconnecting the Legend®.
3. New plumbing lines should be flushed out before installing the Legend®.
4. The Legend®should not be used to remove plaster dust in new pools.
5. Always remove the Legend®before swimmers enter the pool.
6. Always handle the Legend®with care. Do not let children or pets play with the unit: it is not a toy.
7. Always pick up the Legend®by the Vacuum Tube, especially when lifting the unit out of the water.
8. Unless checking the wheel RPM, do not handle the Legend®while it is operating.
9. Always remove the Legend®from the pool before chemical shock treatments. As a rule, any pool water that is unsafe
for swimming is unsafe for the Legend®.
10. Carefully cut the feed hose following the instructions on Section II..
By following these simple guidelines, you can help protect against injury and prolong the life of your
Legend ®.
IMPORTANT SAFETY PRECAUTIONS
Section 1:
Introduction
Like any mechanical device, the Legend®requires some preventative maintenance and the replacement of certain hard working parts.
We recommend that you have your Legend®checked annually. For best results have your Legend®installed by a qualified swimming
pool professional.
For pool owners with plumbing and mechanical experience, installation instructions are included in this manual.
Please put safety first! Be sure to take your Legend ® out of your pool and store it carefully in a shaded area before anyone enters
the pool.
What to Expect from the Legend®
When operating correctly, the Legend ® will travel randomly throughout the pool, vacuuming and sweeping the bottom. The climbing
ability of the Legend ® is dependent on the pools shape. It will climb better in pools without sharp angles or curves in the transition from
the pool floor to the pool wall.
The Legend ® comes equipped with a Wall Fitting that features a Twist Lock Automatic Pressure Relief Valve. If the Legend ® is
receiving too much water pressure to the unit, the relief valve can be manually adjusted to reduce water pressure.
Approximately every three minutes and 30 seconds the Legend ® will go into a back up mode. At this time the Back Up Valve will pull
the Legend ® away from it’s current location increasing it’s random pattern.
The Sweep Hose operates in a gentle sweeping motion to prevent debris from becoming trapped in hard to reach corners of the pool.

Cutting the Feed Hose
The Hose assembly comes in 5 sections now covering approximately 9 m. of the pool, which provides ample hose for most residential
pools. The Back-Up Valve is now 75 cm from the head cleaner and should always remain this distance. For larger pools, see figure 9
for instructions on Adding Additional Feeder Hose.

MEASURE AND MARK THE WATER LEVEL
DEEPEST END OF POOL
MAIN DRAIN
Figure 4
1. Take Feeder Hose out of box (it will be approximately 9 meters long). Before installing the unit, you should lay the feed hose
out straight in the sun, (for one day if possible). The hose has been curled up in the box and sometimes will go around in a
circle. If this happens, take the first or second section of hose from the wall and reverse it, (turn it around). You might have to
reverse both sections to correct the problem. Make sure the feed hose is cut and installed properly.
2. Measure how deep your pool is by using your telepole or the clear end of the feeder hose. Cut the clear (soft) hose equal to
the depth of your pool. (Hint: the grate or domed main drain at the bottom is usually the deepest point.)
Example: The clear (soft) hose is 3 m. long, if the pool is 2,5 m. deep, cut 0,5 m. off of the clear (soft) hose. If the depth is
greater than 3 m., do not cut the clear (soft) hose.
STEPS
1. With the feed hose assembly attached to the pool wall, hold the feed hose
assembly by the opposite end with the clear hose and walk the perimeter of
the pool to locate the farthest point on the perimeter from the wall tting without
stretching the hose assembly.
2. Measure the distance that the hose assembly extends beyond the pool perimeter
farthest point located in Step 1 — (2,3 m in this example).
3. Cut half of the lenght obtained from Step 2 — (1 m in this example), equally from
each of the 3 meter lengths of white or grey hose on either side of the marked
swivel.

4. Attach feed hose to the wall fitting and attach wall fitting
to the pool wall. Hold the end of clear (soft) hose and
walk the perimeter of the pool keeping the hose straight
(do not stretch hose) to find the farthest point of the pool
from the wall fitting.
5. Measure the excess length between the farthest point
of the pool from Wall Fitting and the end of 75 cm clear
(soft) hose.
6. Half of this measured length is to be cut equally from
3 m. white (hard) hoses next to the Marked Swivel.
(Example: Half of 180 cm. = 90 cm. each). If you are
cutting more than 60 cm. off the hoses, remove the floats
next to the Marked Swivel from both hoses. See figures 5
and 6.
7. Re-assemble the hoses and the swivel using mender
nuts, see the figure 8. Put mender nut on swivels first,
then push hose over swivel, rotate mender nut over
hose clockwise until tight. Note: Keep as many floats as
possible on white feed hoses spaced evenly apart to hold
hose up on top of water.
8. When cutting hoses, please use strong scissors or a
sharp knife. Be sure to slide the floats out of the way
when cutting hose.
9. Put extra mender nut on the Legend ® mast and push
clear (soft) hose gently over mast at 1/2”, turn mender nut
around clear (soft) hose tight. Note: The Back-Up Valve
still should be 30” from the head of the cleaner.

10. Now take the bag out of the box and firmly twist lock bag onto the top of Legend ® throat over rubber debris valve.
11. Review and check list: White and clear hoses cut properly and floats evenly spaced. Mender nuts tight around swivels,
Back-Up Valve, Legend ® mast and wall fitting. Make sure wall fitting is securely locked into place.
12. Lower your complete Legend ® assembly into your pool carefully. It should look like figure 10.
13. Go back to your equipment and turn filter pump on first (wait 30 seconds to force air out of the hose), then turn booster
pump on.
14. For adding additional feeder hose for large pools requiring more hose length you will need to purchase one (1) additional
hose, four (4) floats, one (1) swivel and two (2) mender nuts. Attach extra white (hard) hose between clear (soft) hose and
existing white (hard) hose, using floats, swivel and mender nuts. Divide extra white (hard) hose overage by three (3) this
time to keep all white the same length.

Checking Operation
When operating correctly, the Legend ® will travel in 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.
The Legend ® comes with a Twist Lock Pressure Relief Valve
(Wall Fitting). If the Legend ® is receiving too much water
pressure, the Relief Valve in the Wall Fitting will release the
excess water pressure.
BACK-UP VALVE
MBUVP
SCREW
Figure 11
Approximately every three minutes and 30 seconds the Legend ® will go into a back-up mode. The Back-Up Valve cycle time, while in
the back-up mode, is approximately 30 seconds, pulling the Legend ® from it’s current location increasing it’s random pattern.
New Back-Up Valve Information:
The Back-Up Valve Insert which slides into the slot over the jet of the valve. This is secured with a stainless steel screw as shown in
the diagram. The insert will be set from the factory with the larger (3/8”) hole over the opening of the jet. The larger hole is used for the
Legend®cleaner. If you change the insert to the smaller (1/4”) hole, the Back-Up Valve will have increased jet pressure and possibly
tangle your hose.
The Sweep Hose operates in a gentle sweeping motion to prevent debris from becoming trapped in hard to reach corners of the pools.
If the Legend ® does not travel to all areas of the pool, turn off the booster pump and pool filtration pump and make the necessary
adjustments from the instructions in the next section.

1. Thrust Jet Adjustment
There is a Thrust Jet located in the back of the Legend ®.
This Thrust Jet alters the direction of the cleaner. The factory
standard position for the jet is set in the middle and straight
out.
(See Figure 12)
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 counter-clockwise to increase the motion of the
Sweep Hose.
3. Checking Wheel RPM
To determine whether the Legend ® is receiving the proper
water pressure, turn off the pool pump, and carefully remove
the Legend ® from the pool.
Mark the front drive Tire/Wheel with a marker, or use the
Pentair 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 and the booster pump
while you place the Legend ® 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 ® operates between
28-32 RPM. If the RPM is below 28 then call your local Pool
Professional.
If the RPM is more than 32, at the Wall Fitting, unscrew the
Pressure Relief Valve slowly until the RPM falls between
28-32.

Your debris bag is ready to be reinstalled onto your cleaner.
If you have a lot of debris in your pool, especially after a storm,
you can run your Legend ® in two shorter cycles per day and
empty the debris bag between cycles.
Reconnect the debris bag to the vacuum tube. Do NOT over turn.
A Helpful Hint: It is easier to empty the debris bag when it is dry.
A second bag may be used while the full debris bag is drying.
It’s best to empty the debris bag when it becomes half full.
The Legend ® will have better performance if the bag is not
overloaded
Periodic Maintenance
The following parts are wear items that should be checked, maintained or replaced as needed. Wear items are considered any
working or moving part(s) being worn due to the use of the cleaner.
Wear items are not covered under warranty.
1. Wall Fitting Screen
Inside the wall fitting is a filter screen that acts as a secondary filter. This screen is to keep debris that is passed by the pool filter
out of the Legend ®. Running the Cleaner without the filter screen can damage the Legend ® and will void the warranty.
A continuous plugged or dirty screen is a sign of problems in your pool filtration system and you need to contact your local Pool
Professional.

2. Tires & Bearings
The tires are designed to protect the bottom of your pool and provide better traction. You need to rotate or replace the tires when
the tire is worn up to the wear groove.
The Wheel Bearings are warranted free of defects when shipped from Pentair Water Pool and Spa, Inc., and are considered a
wear item. A good bearing will spin freely.
3. Roller Rings
Your Sweep Hose has a series of Roller Rings to protect the Sweep Hose. Replace the rings as needed. You can rotate the
Roller Rings to prevent flat spots.
4. Debris Bags
Fine Mesh Sand & Silt Bag
The Legend ® comes with a Sand & Silt bag for general use in all pools. We do not recommend using the fine mesh bag to pick
up leaves and twigs or other large debris for they have sharp points and edges that can poke holes and eventually rip the bag.
Optional Leaf Bag
The leaf bag is a larger mesh bag made to pick up heavier debris such as leaves. twigs, acorns, etc. This bag can be helpful
especially after a storm.
A Helpful Hint: To prolong the life of bags, remove the cleaner from pool before adding chemicals.
5. Sweep Hose
The Sweep Hose is provided to help keep the bottom and sides of your pool clean. The Sweep Hose is warranted free of
defects when shipped from the factory, and is considered a wear item.
6. Debris Valve
This valve is located under the Debris Bag, it is designed to keep the debris inside the bag. It functions like a check valve to
allow the debris to only enter through the bag one way. Replacement is needed when valve begins to stiffen.
Back Washing the Pool Filter
Always disconnect the Legend ® from the pool wall before cleaning or back washing the pool filter. After cleaning or back
washing, let the pool filtration system run for a minimum of five minutes to flush out the return lines before reconnecting the
Legend ®.
Storage and Winterizing
Never leave or store the Legend ® in direct sunlight. When storing the Legend ® for the winter, be sure to drain all the water from
it. This is important since freeze damage is not covered under the warranty. Also, remove the Wall Fitting.
