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.
• Never operate the cleaner with people or pets in the
pool.
• Never operate the cleaner unless submerged under
the water.
• A dedicated suction line should have a Vac Lock®
installed for safety.

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.
We will refer to all versions as “cleaner” throughout this guide with
notations as to old or new style.

Pre-Installation Checklist
The majority of issues experienced with the cleaner are due to
improper installation or expectations. The following pre-installation
checklist will ensure correct performance.
• Is the pump size adequate to supply enough suction to operate
the cleaner (use the flow gauge)?
• If using the skimmer, does it have one port or two? If only one
port, the main drain may need to be shut off or disabled.
• If you have a dedicated suction line, make sure it is the right
size (at least 1 ½”) and has a “Vac-Lock” for safety.
• The pool must have at least a 7” radius to climb walls.
• The cleaner is not designed to be used to clean a pool with
heavy construction debris or heavy storm debris. It is designed
to maintain a clean pool.
• The cleaner will not clean steps and loveseats, and may not
work well under a cover.

Pre-Installation Checklist (Continued)
• Remove all large objects from the pool that could interfere
with the operation of the cleaner.
• Treat and remove algae from the pool water and surfaces.
• Check and balance the water chemistry.
• Make sure the water level in the pool is correct.
• Clean or backwash the filter.
• Empty the pump strainer and skimmer baskets.

Installation
Page 6
Connect hoses as
shown
Leader hose is
connected to the
Cleaner head
1. 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.

Installation
Page 7
2. Fill the hose with water and eliminate all air that is trapped within
the hose. This is done by submerging the entire hose.
3. Connect the flow gauge to the leader hose and clip it to the first
hose as shown (fig 1)
4. With the pump off attach hose to the skimmer (fig 2) or “Vac Lock”
(fig 3)

Installation

Figure 4
5. 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).
Note: A regulator valve (for skimmer) (fig 5) or a valve
(dedicated line) (fig 6) may be needed to reduce suction.

6. Remove the flow gauge and store for future use.
7. Check the rear flap adjuster at the left rear of the cleaner. It should be set
to Position II (fig 7)
8. Check to make sure all returns are pointed down. Returns pointed up can
interfere with the hose. Some pools may need directional eyeballs added.
9. Submerge the cleaner head and rotate to remove all air.
10. Remove the red label and connect the leader hose (fig 8)
Installation

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. Periodically check the water flow. Too much
vacuum is as bad as too little.
5. Periodically check the wings, flaps and shoes.
Worn parts will affect the performance of the
cleaner. Other parts damaged by worn out wear
parts are not covered under warranty.
