The Hayward Navigator Pro may be moving slowly or getting stuck due to excessive suction, which can cause the hose to collapse. To fix this, check that the hose angle at the skimmer is not too sharp and reduce suction using the regulator valve. If necessary, stack two regulator valves to further reduce suction, especially when using large pumps. Additionally, inspect the turbine and flaps for blockages or disconnections, as debris can prevent proper movement.

Page 3: Safety Precautions
Safety Precautions • Use only the “In Line Flow Gauge” provided to check the system vacuum (or suction). • Never use your hand to verify the amount of vacuum at the skimmer or dedicated suction line. • Keep hands and fingers away from the access cover and any moving part while the cleaner is operating.
Page 4: Cleaner Overview
Cleaner Overview This guide will cover the current Navigator Pro and new Pool Vac XL as well as the previous Navigator and Pool Vac Ultra. Each version has a model designed for Gunite or Vinyl applications. While the colors, shell shapes, names, specific areas of disassembly may be different, the majority of the major components of these cleaners are interchangeable.

Page 8: Installation
Installation Starting with the leader hose, connect the four foot hose sections until they reach eight feet (two hose lengths) past the furthest point Note: Although 10 hoses section are provided, the installation may require more. Connect hoses as shown Leader hose is connected to the Cleaner head...
Page 9 Installation Fill the hose with water and eliminate all air that is trapped within the hose. This is done by submerging the entire hose. Connect the flow gauge to the leader hose and clip it to the first hose as shown (fig 1) With the pump off attach hose to the skimmer (fig 2) or “Vac Lock”...
Page 10 Installation Turn the pump on and check the flow to the unit by using the flow gauge (submerged). The flow must be between the “min” and “max” (fig 4). Figure 4 Note: A regulator valve (for skimmer) (fig 5) or a valve (dedicated line) (fig 6) may be needed to reduce suction.
Page 11 Installation Remove the flow gauge and store for future use. Check the rear flap adjuster at the left rear of the cleaner. It should be set to Position II (fig 7) Check to make sure all returns are pointed down. Returns pointed up can interfere with the hose.
Page 12 Operational Tips 1. Disconnect the cleaner from vacuum source during backwashing. 2. Never coil the hose when cleaner is removed from pool. Always store straight. 3. Never leave the leader hose attached to the head when it is out of the pool. 4.

Page 37: Hang Test
Troubleshooting/Hang Test Step A Before getting started with troubleshooting, understanding how the Hang Test is performed will help in diagnosing a problem. Before using the test or performing any other test, attach the flow gauge and make sure the suction setting is correct, See page 8 .
Page 38 Troubleshooting/Hang Test Does the cleaner rotate in both directions with a Step B stop in-between in a 5 minute time period If the cleaner turns in one If the cleaner does not turn at direction only go to page 26. all go to page 26 or 34 or check the rear screen for debris.
Page 39 Troubleshooting/Hang Test Doing this test pool side is invaluable. For the retail or service dealers retail location this test can be accomplished using air. Procuring at least a 3hp Shop-Vac along with a cleaner leader hose gets you most of the way towards building your own in-house cleaner tester.
Page 40: Troubleshooting
Troubleshooting Cleaner does not move Verify the suction setting is correct (page 8). If the suction is Step A correct go to Step B. After confirming proper suction, place the cleaner on Step B the pool floor. If the cleaner does not move, check the shoes for wear and the pool surface for algae (treat and remove) or remove the access cover and check for debris in the turbine area.
Page 41: Cleaner Turns In One Direction
Troubleshooting Cleaner turns in one direction Perform Hang Test on page 35 & 36. If Cleaner turns in both Step A directions correctly go to Step B If the cleaner while on the bottom of the pool goes in circles in Step B only one direction, or turns heavily in only one direction, there is excessive play or wear between the A-frame and turbine, A-frame...
Page 42 Troubleshooting Cleaner goes too slow or fast Verify the suction setting is correct (page 8). If the suction is Step A correct go to Step B. Check and replace any worn shoes, wings or flaps. If the Step B problem is not solved go to step C Note wear indicators on these parts See page 21 See pages 16 &...
Page 43 Troubleshooting Cleaner goes too slow or fast Check and make sure pods are tightly connected to A-frames. Step C If connection becomes loose shortly after tightening replace both A-frames and pods. If problem persists go to Step D See pages 18, 19 or 20 Check turbine for wear or correct Step D placement.
Page 44: Cleaner Is Floating Or Lifting
Troubleshooting Cleaner is floating or lifting, Hose is twisting or curling Note: Since the cleaner is heavier than water, the only way it can float is from an external source. This is usually caused by air trapped in the cleaner or on the hose. Ensure all air is removed from the cleaner and hoses.
Page 45 Troubleshooting Cleaner Gets Stuck In Corners or on Steps Verify the suction setting is correct (page 8). A cleaner running Step A too slow or too fast may not turn off a step or corner. If the suction is correct go to Step B. Check return fittings direction.

Page 49: Hose Collapsing
Troubleshooting Hose Collapsing If using the cleaner with a skimmer, make sure the angle Step A where the hose attaches to the skimmer is not too sharp. The suction may be too great. Reduce the suction by using the Step B regulator valve.
