IMPORTANT WARNING AND SAFETY INSTRUCTIONS

LEGEND® INSTALLATION MANUAL

DISCLAIMER OF LIABILITY

Important Notice About Your Pool and Legend® Cleaner:

There are a multitude of factors that contribute to the life of your pool. The Legend® automatic pool cleaner
is a very passive product that will have no impact on pool life.

Please be aware that over time, deterioration, discoloration and brittleness of any pool finish can be caused
separately by, or in combination with, age, an imbalance in pool water chemistry, improper installation and
other factors. An automatic pool cleaner, such as the Legend®, will not remove or cause wear on “good” pool
plaster. In fact, the opposite is true—pool plaster will eventually cause wear on the cleaner.

The same situation holds true for vinyl-lined inground swimming pools, because vinyl liners are also
affected by the environment and factors such as pool water chemistry, sunlight and the pool’s surroundings.

Therefore over time, vinyl can become brittle and weak. In addition, vinyl-lined pools are affected by the
workmanship, composition and installation of the liner and the workmanship and quality of construction of
the supporting walls and pool base. These are all factors which can contribute to liner failure. The existence

of any of these type of conditions in your pool is not caused by the use or operation of the Legend

®

cleaner.

Pre-installation Check List

Before installing your cleaner, review and understand all warnings and safety information in this guide.
Failure to follow these instructions or improper installation of the cleaner can result in damage to the pool
finish or the vinyl liner, Pentair Water Pool and Spa, Inc. disclaims any liability for repairs or replacement to

any of these structures or components of the customer’s pool.

Before installing the cleaner in a vinyl liner pool:

Before installing the pool cleaner, examine the interior of your pool carefully. Check liner closely for signs of deterioration or damage from
age, chemicals, pool wall damage, etc. If any damage is found, have a qualified pool professional make all the necessary repairs. Also,
if your vinyl liner is brittle or has stones, wrinkles, roots or metal corrosion in contact with the underside of the liner, or has damage to
the base or supporting walls, do not install the pool cleaner before having a qualified professional perform the necessary repairs.

Before installing the cleaner in a gunite pool or a pool that is partially or completely tiled:

Before installing the pool cleaner in a gunite pool or pool that is partially or completely tiled; check closely for loose tiles and loose light
fittings. Do not install the pool cleaner before having a qualified professional perform the necessary repairs.

Before installing the cleaner, clean your filter system:

Make sure you have cleaned the filter, including backwashing, rinsing, and emptying all baskets. A clean system is necessary for proper
cleaner operation and coverage.

Before installing the cleaner, fill the hose with water:

Always make sure the cleaner head is submerged and the hose is full of water before connecting the hose to the filtration system
(whether through a skimmer or dedicated wall fitting). Air in the system can damage the pump through dry running and overheating.

Before installing the cleaner, understand cleaner coverage:

The cleaner is designed to rid your pool of debris in approximately 4-6 hours. Less time could be needed, depending on the pool size.
The cleaner was not designed to automatically clean steps or swimouts or to work under a solar cover. It was also not designed to do
initial cleanup for a new pool or when opening your pool for the season.

AFTER installing the cleaner, make sure the cleaner is operating correctly:

The cleaner may need some minor adjustments to make sure it is operating properly so there is no damage to the pool finish. Certain
vinyl liner patterns are particularly susceptible to surface wear, pattern removal, ink rubbing off of, or serious scratches to the pattern
caused by objects coming into contact with the vinyl surface, including automatic pool cleaners. Pentair Water Pool and Spa, Inc. is
not responsible for any pattern removal, abrasions or markings on vinyl liners.

LEGEND® INSTALLATION MANUAL

Important Information:

The Legend® automatic pool cleaner comes ready to connect into a female threaded 1-1/2" (38mm) line,
dedicated to our Universal Booster Pump. Also, if you have a chlorinator, solar system or other air
inducing equipment, please contact our Technical Support Department at 1-800-831-7133 [USA] or
{Herentals – Belgium +32 (0) 14.25.99.11}, before you install the Legend®. (See diagram on Page 8.)

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 handle, 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 Page 9.

By following these simple guidelines, you can help protect against injury and prolong the life
of your Legend®.

Before the Legend® is installed, please take a moment to record the serial number. This number is
located on your warranty card and on the back of the Legend® near the rear jet. You will be asked for

this number when you contact our Technical Support Department.

LEGEND® INSTALLATION MANUAL

I. Introduction

A. Thank You for Choosing the Legend® Pool Cleaner

Congratulations on the purchase of your new automatic pool cleaner. The Legend® is designed to give
you years of dependable and efficient service. With the Legend®, you and your family will spend more
time relaxing and enjoying your pool and less time cleaning it.

The Legend® has been designed and built with time proven features andinnovations to create
an automatic pool cleaner that will give you years of dependable service. The Legend® is built with pride
by people who care about the product using state of the art materials and backed by a limited warranty
that protects against defects in parts and construction.

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.

B. 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 (Part# EW22/LLW22PM) 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.

D. Installing the Twist Lock Pressure Relief Valve

(Wall Fitting)

1. Take out any existing pool cleaner and/or wall
fitting.

2. Turn on the filtration pump and booster pump,
flush out the plumbing line.

3. Turn off filter pump and booster pump.

4. Remove the Wall Adapter from the Wall Fitting
and screw Adapter by hand into the dedicated
line. Turn until tight.

5. Take the Wall Fitting and Twist Lock the Wall
Fitting into the Wall Adapter 1/4 turn and pull
out; to a snug fit. Once the Wall Adapter is secure,
you can now twist lock and unlock to remove
Wall Fitting with ease from the Wall Adapter.

E. Cutting the Feed Hose

(See Hose Diagrams on Page 10)

The Hose assembly comes in 5 sections now covering approximately 30 ft. (9 m) of the pool, which
provides ample hose for most residential pools. The Back-Up Valve is now 30" (75 cm) from the head
cleaner and should always remain this distance. For larger pools, see #14 on Page 12 for instructions on

Adding Additional Feeder Hose

.

1. Take Feeder Hose out of box (it will be approximately 30 feet [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 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 soft hose is 10 ft. (3 m)
long, if the pool is 8½ ft. (2,5 m) deep,
cut 1½ ft. (0,5 m) off of the soft hose. If
the depth is greater than 10 ft. (3 m), do
not cut the soft hose.

E. Cutting the Feed Hose

- (cont.)

3. Lay the telepole next to the soft
hose. If the clear soft hose is
longer than the mark on the
telepole, cut the excess from the
end attached to the white (hard)
hose. Do not cut off the float.
Leave the first float in position
next to the Back-Up Valve. Place
the second float midway between
the first float and the Hose Swivel.

4. Attach feed hose to the wall fitting
and attach wall fitting to the pool wall. Hold the end of 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
30 in. (75 cm) soft hose.

6. Half of this measured length is to be cut equally from 10 ft. (3 m.) white (hard) hoses next to the
Marked Swivel. (

Example:

Half of 6 ft. [180 cm] = 3 ft. [90 cm] each). If you are cutting more than
2 ft. (60 cm) off the hoses, remove the floats next to the Marked Swivel from both hoses. See
Diagrams on Page 10.

7. Re-assemble the hoses and the swivel using
mender nuts. 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.

LEGEND® INSTALLATION MANUAL

F. 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.

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") [0.9525 cm] 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")
[0.635 cm] 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 pool.

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.

G. Fine Tuning the Legend

®

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 illustration – 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 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.

G. Fine Tuning the Legend®

- (cont.)

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 or contact our Technical Support
Department at 1-800-831-7133 [USA] or {Herentals – Belgium +32 (0) 14.25.99.11}.

If the RPM is more than 32, at the Wall Fitting, unscrew the Pressure Relief Valve slowly until the RPM
falls between 28-32.

If you have any additional questions, please contact Pentair Water Pool and Spa, Inc., Technical
Support Department at:1-800-831-7133 [USA] or {Herentals – Belgium +32 (0) 14.25.99.11}, Monday
through Friday.

III. Operation/Periodic Maintenance

A. Connecting/Disconnecting the Legend

®

Turn off the booster pump and pool pump. Then take the Wall Fitting and twist lock the Wall Fitting
clockwise into the Wall Adapter. To disconnect the Legend®, unlock and twist counter-clockwise. The
Wall Adapter should remain in the pool wall.

B. Turning On/Off the Legend

®

The Legend® operates off the booster pump coming from the equipment pad, and can be turned on or off
by merely turning on/off your booster pump time clock.

C. Cleaning the Sand & Silt Bag

Carefully unlock the debris bag from the vacuum tube. Use
your thumb to push the "U" shaped snap lock closure upward
until it snaps open. Make sure to swing it away from the
opening. Open the bag and remove debris.

To close, push the middle of bag inward, as shown, and
bring the edges together to make them stack like an
accordion. Swing the "U" shaped snap lock closure back
to the closing position.

Gently push on top of the "U" shaped snap lock closure to
make sure it snaps into place. Reattach the clip onto the
feed hose.

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.

D. 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.

To clean the filter screen, pull the screen out from inside
the Wall Fitting and rinse thoroughly and push back inside
the Wall Fitting.

Whenever cleaning, back-washing or repairing the filter,
remove the Wall Fitting and flush out the dedicated line before using the Legend

®

III. Operation/Periodic Maintenance - (cont.)

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.

E. 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®.

F. 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.

LEGEND® INSTALLATION MANUAL

To insure the best performance from your cleaner, follow the troubleshooting guide listed below.

IV. TROUBLESHOOTING AND PERFORMANCE TIPS

Problem

Legend® doesn't move or moves
sluggishly or hangs up on steps.

Legend

®

falling over or lying on its

side.

Legend

®

will not back up.

Legend® will not climb.

Hoses tangling.

Sweep Hose is sucked into the
cleaner.

Booster Pump very noisy.

Sweep Hose breaks water surface
and sprays nearby windows, patio
decks and bystanders.

Solution

1. Be sure filter pump and booster pump are on and working properly. (You may need
to clean your pool filter system).

2. Check the Wall Fitting screen for debris and rinse clean.

3. Check wheel RPM, (see page 14).

4. Determine if the Back-Up Valve is cycling. (Hold the valve out of the water and the
jet should come on for approx. 30 seconds and shut off for approx. 3 minutes and
30 seconds.)

5. Check all the Hose connections and Swivels for leaks that can cause loss of water
pressure.

6. Check debris that may be jammed in the gear teeth on one of the front drive wheels.
Gently rotate the front wheels backward to dislodge debris.

1. This usually indicates the bag needs to be emptied.

2. Check to see if the ballast float (EA20) is leaking by checking if there is water inside.
Unscrew by pulling back while turning counter-clockwise. When it comes off, shake
it and listen for water in the float.

1. Determine if the Back-Up Valve is cycling. (Hold the valve out of the water and the
jet should come on for approx. 30 seconds, and shut off for approx. 3 minutes and
30 seconds).

2. Check the wheel RPM, (see page 14).

3. Empty the debris bag if full or half full.

1. Even if your pool doesn't show algae you still need to brush the sides of the pool
wall.

2. Check the wheel RPM, (see page 14).

3. Reposition the Thrust Jet. Loosen the two screws to adjust the Thrust Jet,
(see page 13).

A Reminder: The climbing ability of the Legend® is dependent on the pool's shape and

available water pressure. It will climb better in pools without sharp angles or curves
in the transition from the pool floor to the pool wall.

1. Check the length of the Feed Hose, they may be to long, (see pages 9-12).

2. Check to see that the Feed Hose is floating on top of surface. Check hose floats
for even spacing.

3. Twist the Hose Swivels to see if they spin freel and replace any that will not.

4. Lay out the Feed Hose straight in the full sun to remove any memory.

1. Adjust the Sweep Hose using the Adjustment Screw located on the bottom of the
Swivel Mast and just below the upper Thrust Jet. Turn Adjustment Screw clockwise
until the Sweep Hose is in a gentle sweeping motion.

1. Make sure Wall Fitting is mounted in pool wall correctly.

2. Make sure Pool Filtration system is working properly.

3. Contact your local Pool Professional - possible Booster Pump problem.

1. Adjust Sweep Hose to a gentle sweeping motion.

2. Add optional Sweep Hose weight, (see page 16).
