The following are important facts to remember before installing and operating the Legend

®

II.

1. Always disconnect the Legend® II 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® II.

3. New plumbing lines should be flushed out before installing the Legend® II.

4. The Legend® II should not be used to remove plaster dust in new pools.

5. Always remove the Legend® II before swimmers enter the pool.

6. Always handle the Legend® II with care. Do not let children or pets play with the unit: it is not a toy.

7. Always pick up the Legend® II by the Vacuum Tube especially when lifting the unit out of the water.

8. Unless checking the wheel RPM, do not handle the Legend® II while it is operating.

9. Always remove the Legend® II from the pool before chemical shock treatments. As a rule, any pool

water that is unsafe for swimming is unsafe for the Legend® II.

10. Carefully cut the feed hose following the instructions on Page 3.

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

Before the Legend® II 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® II near the rear jet. You will be asked this
number when you contact our Technical Support Department.

I. Introduction

A. Thank You for Choosing the

Legend

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

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

B. What to Expect from the Legend® II

When operating correctly, the Legend® II will travel
randomly throughout the pool, vacuuming and
sweeping the bottom. The climbing ability of the
Legend® 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® II comes equipped with a Wall Fitting
(Part#LXW22) that features a Twist Lock Automatic
Pressure Relief Valve. If the Legend® 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® II will go into a back up mode. At this
time the Back Up Valve will pull the Legend® 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® 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® 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).
