Safety Precautions
•Use only the 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.

Navigator & Pool Vac Ultra Overview
Hayward currently offers two suction cleaners for in-ground pools, the Navigator
and the Pool Vac Ultra (PVU) and each version has a model designed for
Gunite or Vinyl applications. While the colors, shell shapes, and names may be
different, the majority of the major components of these cleaners are
interchangeable.
We will refer to all versions as “cleaner”
throughout this presentation.

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.
•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 12” 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.
