LEGEND® PLATINUM II INSTALLATION MANUAL • MANUEL D’INSTALLATION LEGEND® PLATINUM II

I. Introduction

A. Thank You for Choosing the

Legend

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

The Legend
with time proven features and patented innovations
to create an automatic pool cleaner that will give you
years of dependable service. The Legend® Platinum
II is built with pride in the U.S.A., 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® Platinum II
requires some preventative maintenance and the
replacement of certain working parts. We
recommend that you have your Legend® Platinum II
checked annually. For best results have your
Legend® Platinum II 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® Platinum II out of your pool and store it
carefully in a shaded area before anyone enters the
pool.

Platinum II Pool Cleaner

®

Platinum II, you

®

Platinum II has been designed and built

B. What to Expect from the

®

Legend

When operating correctly, the Legend® Platinum II
will travel randomly throughout the pool, vacuuming
and sweeping the bottom. The climbing ability of the
Legend® Platinum II 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® Platinum II comes equipped with a Wall
Fitting (Part# LXW22) that features a Twist Lock
Automatic Pressure Relief Valve. If the Legend
Platinum II is receiving too much water pressure to
the unit, the relief valve will automatically reduce
water pressure.

Approximately every three minutes and 30 seconds
the Legend® Platinum II will go into a back up mode.
At this time the Back Up Valve will pull the Legend
Platinum II away from problem areas.

Occasionally some vinyl pools have steps installed
so the unit may not climb and remains stationary until
the Back Up Valve pulls the unit away from the steps.
When this occurs you need to use the optional
Step Adapter (Part# EU13) to prevent wearing the
vinyl liner.

The Sweep Hose operates in a gentle sweeping
motion to prevent debris from becoming trapped in
hard to reach corners of the pool.

D. Pressure Testing Instructions

1. Make sure the pool filter is clean before
conducting this pressure test.

2. Twist lock the Wall Fitting with Feeder Hose into
the Wall Adapter.

3. Have someone hold the Pressure Tester end of
the Feed Hose beneath the water while you turn
on the pool pump. Continue holding the hose
under the water and cover the large hole of the
pressure tester.

4. Reach down and feel around the Pressure Relief
Valve on the Wall Fitting to see if the Relief Valve
is releasing any water pressure. If valve is
releasing water pressure go on to Section E.
If it is not, the pool filtration pump may not have
sufficient amount of water pressure to operate
the Legend® Platinum II.

BEFORE YOU GO TO THE NEXT STEP,
CONTACT OUR TECHNICAL SUPPORT
DEPARTMENT AT: 1-800-831-7133

2. With the pool pump on, hold the free end of the
Feeder Hose underwater. Gently pull the hose
to the farthest end of the corner of the pool, do
not stretch the hose. (The Legend® Platinum II
usually will not climb the top step, so you do not
need to include it in the measurement.) If the
hose just reaches the farthest point of your pool,
and without any excess hose hanging over the
deck, then go to Section F.

3. If the Feeder Hose extends past the farthest end
of the pool, mark the excess hose hanging over
the deck, turn off your pool pump, and cut first 6
ft. section of hose, closest to the wall, the length
of excess.

4. IMPORTANT: Please double check the hose
length to insure you will be getting the maximum
performance from your pool cleaner. The hose
lengthens when under pressure (when your
pump is on).

E. Cutting the Feed Hose

(See Hose Diagram on Page 11)

The Hose assembly comes in 6 sections covering
approximately 30 ft. of the pool, which provides ample
hose for most residential pools. For larger or smaller
pools see Page 12 for instructions for Adding or
Deleting Additional Feeder Hose.

1. Take Feeder Hose out of box and lay the hose
straight in the sun for one day if possible, (this
will take any memory out of the hose due to being
coiled up in the box).

LEGEND® PLATINUM II INSTALLATION MANUAL • MANUEL D’INSTALLATION LEGEND® PLATINUM II

F. Hooking up the Legend® Platinum II

1. Remove the Pressure Tester from the free end of
the Feeder Hose by unscrewing the Hose Nut.
Left hand thread (reverse), (see illustration,
previous page).

2. Place mender nut on Legend® Platinum II Swivel
Mast. Connect the open end of the Feed Hose
to the top of the Legend® Platinum II Swivel Mast
and secure with the mender nut. The arch of the
Feed Hose should align in the same direction
as the Swivel Mast, there should be no twist in
the Feed Hose after connection. (See illustration
below.)

4. Gently place the Legend® Platinum II in the pool.
Turn on the pool filtration pump.

5. Check to make sure the wheel RPM is between
25-32. See page 5 for instructions on wheel
RPM.

G. Checking Operation

When operating correctly, the Legend® Platinum II
will travel in a random pattern throughout the pool,
vacuuming and sweeping the bottom. The climbing
ability of the Legend® Platinum II 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® Platinum II comes with a Twist Lock
Pressure Relief Valve (Wall Fitting). If the Legend
Platinum II is receiving too much water pressure, the
Pressure Relief Valve in the Wall Fitting will release
the excess water pressure.

Approximately every three minutes and 30 seconds
the Legend® Platinum II 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® Platinum II from problem areas.

®

3. Carefully twist lock the Sand & Silt debris bag
onto the top of the Legend® Platinum II Vacuum
Tube. Make sure there is a Rubber Debris Valve
attached to the top of the Vacuum Tube before
locking on the Sand & Silt bag, (this valve is
similar to a check valve to help keep debris
inside the bag when the water pressure is off).

4

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® Platinum II does not travel to all areas
of the pool, turn off the pool filtration pump and make
the necessary adjustments from the instructions on
the next page.

LEGEND® PLATINUM II INSTALLATION MANUAL • MANUEL D’INSTALLATION LEGEND® PLATINUM II

H. Fine Tuning the Legend® Platinum II

1. Thrust Jet Adjustment

There are two Thrust Jets located in the back of the
Legend® Platinum 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® Platinum 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® Platinum II is
receiving the proper water pressure, turn off the pool
pump, and carefully remove the Legend® Platinum II
from the pool.

Patents Pending

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.

LEGEND® PLATINUM II INSTALLATION MANUAL • MANUEL D’INSTALLATION LEGEND® PLATINUM II

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® Platinum 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® Platinum II
operates between 25-32 RPM. If the RPM is below
25 then closely follow the instructions on the next
page.

5

3. Checking RPM - (cont.)

1. Clean the Screen located inside the Wall Fitting.
A small amount of debris will significantly affect
the performance of the cleaner.

2. Clean the skimmer basket, pump basket and
pool filter.

3. If an adjustable Gate (3-way) Valve has been
installed, adjust the valve to increase water flow
to the Legend® Platinum II.

4. If the RPM is more than 32, at the Wall Fitting,
unscrew the Pressure Relief Valve slowly until
the RPM falls between 25-32. Again, if an
adjustable gate (3-way) valve has been installed,
adjust the gate valve to decrease water flow to
the Legend® Platinum II.

5. If you continue to have problems with either the
water flow or obtaining the specified water
pressure to operate the Legend® Platinum II, call
your Professional Pool Dealer.

If you have any additional questions, please

contact Pentair Water Pool and Spa, Inc.,

Platinum II,

B. Turning On/Off the

Legend® Platinum II

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

C. Cleaning the Sand & Silt Bag

Carefully unlock the debris bag from the vacuum tube
and open the Velcro® Brand fastener at the top of
debris bag and dump debris.

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® Platinum II.

Running the Cleaner without the filter screen can
damage the Legend® Platinum II and will void the
warranty.

If you have a lot of debris in your pool, especially
after a storm, you can run your Legend® Platinum II
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.

If the Velcro® Brand fastener on top of the debris bag
does not stay secure, rinse well, let it dry and clean
with a stiff brush.

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® Platinum II will have better
performance if the bag is not overloaded.

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 filter,
remove the wall fitting and flush out the dedicated
line before using the Legend® Platinum II.

2. Tires & Bearings

The tires are designed to protect the bottom of your
pool and provide better traction. You need to rotate
the tires once per year.

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® Platinum II 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
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® Platinum II 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® Platinum II.
