LEGEND® II INSTALLATION MANUAL
To insure the best performance from your cleaner,
follow the troubleshooting guide listed below.
IV. TROUBLESHOOTING AND PERFORMANCE TIPS
Problem: Legend ® II will not back up.
Solution: 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 pages 5-6 ).
3. Empty the debris bag if full or half full.
Problem: Legend ® II will not climb.
Solution: 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 pages 5-6 ).
3. Reposition the Thrust Jet. Loosen the
two screws to adjust the Thrust Jet.
A reminder: The climbing ability of the Legend ® II 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.
Problem: Hoses tangling.
Solution: 1. Check the length of the Feed Hose,
they may be to long. (See pages 3-4 .)
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 freely and replace any that will not.
4. Lay out the Feed Hose straight in the
full sun to remove any memory.
A. PROBLEMS & SOLUTIONS
Problem: Legend ® II doesn't move or moves
sluggishly or hangs up on steps.
Solution: 1. Be sure filter and filter pump are on
and working properly. (You may need
to clean your pool filter system.)
2. Check to see if the skimmer and
basket are clean.
3. Check the Wall Fitting screen for debris
and rinse clean.
4. Check wheel RPM, (see pages 5-6 ).
5. 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.)
6. Check all the Hose connections and
Swivels for leaks that can cause loss
of water pressure.
7. 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.
Problem: Legend ® II flies around pool.
Solution: 1. Check wheel RPM, and if more than
32 RPM make adjustment at Wall
Fitting by turning the Pressure Relief
Valve slowly until RPM falls between
25-32; or if an adjustable gate valve
has been installed, adjust the valve to
decrease water flow.
2. Air in system, see a Pool Professional.
