Jandy AquaPure

AquaPure is the other Jandy salt system, and it is a different shape of product from the TruClear. Where the TruClear is one compact self-contained unit for pools up to 35,000 gallons, AquaPure is a cell plus a separate power center — either Jandy's own AquaPure power pack or a PureLink center — in two cell sizes.

What you get for the extra hardware is instrumentation. AquaPure has a digital salinity readout in grams per liter, plus flow, temperature and status on the display, and it talks to AquaLink automation for salt readings and output control. The TruClear has none of that. If you want to know what your salt level is without a test strip, this is the Jandy that tells you.

You set the cell size by cutting a jumper

This is the thing to know before touching the board, and it has no equivalent on the other brands.

The Power Interface Board leaves the factory configured as a 1400. To run a PLC700, Jandy's instruction is to cut the JL1 jumper with cutting pliers.

Not a menu, not a dip switch — a physical cut. Two consequences follow:

A replacement board arrives as a 1400. If your cell is a seven-blade 700 and nobody re-cuts the jumper, the system drives it as though it had fourteen blades. Anyone fitting R0467600 to a 700 installation has to do this step and it is easy to miss, because the system will run.

It is not reversible in the field. A cut jumper stays cut. Going the other way means a new board.

Hayward's TurboCell has the same class of problem solved differently — its cell type is a controller setting you scroll to, with Hayward warning that the wrong one causes inaccurate salt readings and possible shutdown. Jandy's version is more permanent and less discoverable.

The blade count is the model number, which at least makes the cell itself easy to identify: seven blades is a 700, fourteen is a 1400.

Salt, and where it sits among the four

Jandy asks for 3.0 to 3.5 gpl — 3,000 to 3,500 ppm — with 3.0 as the target, which is the same floor as the TruClear and a little more headroom above it.

The shutdown behavior is where it differs from everything else on the site. Below 2.0 gpl the system turns the cell off automatically, because Jandy states that operating at low salt damages the electrolytic cell. That is a lower floor than Pentair or Hayward, which both stop at 2,600 ppm.

It cuts out at the top as well: if salinity rises above the measurable range the system shuts the cell down, because operating with high salt damages the power center rather than the cell. Two different failure modes at the two ends, which is unusual to see stated.

So across four chlorinators the targets run 3,000, 3,000, 3,200 and 3,600 ppm. There is no universal number, and the salt calculator takes whichever one your equipment asks for.

The Tri-Sensor is one part doing three jobs

Flow, temperature and salinity are all read by a single port sensor — R0452500 on a 16-foot lead, R0476400 on 25.

That matters for diagnosis. A single failed sensor can present as no flow detected, as no salinity reading, or as a salt level that is simply wrong — three complaints that look unrelated and share one cause. Before concluding the cell is finished, replace the sensor; it costs a fraction of an electrode pack.

On startup the system self-calibrates that sensor, displaying Wait while it does. Jandy says it usually takes under six minutes. A unit that appears stuck on Wait for a couple of minutes is behaving normally.

Four numbers for two cells

Ordering is the fiddly part of this product, because each cell comes two ways:

• PLC700 — R0452300 with universal unions, R0475300 with 2 inch threaded PVC unions
• PLC1400 — R0452400 with universal unions, R0475400 with 2 inch threaded PVC unions

All four are 3-port cells. What differs is the unions that join them to the plumbing, so the question is not only which cell but which unions are already on your pipe. Look at what is there before ordering.

The cable and the sensor also come in two lengths each, 16 and 25 feet, and they have to suit the run between the power center and the cell.

The warranty trap specific to a two-piece system

Jandy warrants a complete electronic salt system for three years when the controller and cell are purchased and installed together. Otherwise the one-year default applies.

On a self-contained chlorinator that is hard to get wrong. On AquaPure it is easy: the cell and the power center are genuinely separate purchases, and a replacement cell fitted to a power center bought six years ago is not a complete system. That is a reasonable position on Jandy's part and an expensive surprise if nobody mentions it.

The other rule applies here as everywhere: Jandy's warranty does not apply to anything bought through the Internet or an e-commerce platform. Not a reduced term. The brand page has the whole policy.
