Salt Chlorinator Pool Installation Diagram: 6 Key Steps

Installing a salt chlorinator in a pool is a simpler process than it sounds. Although many users think that it requires a complex reform, the reality is that it is only necessary to integrate it into the existing Pool filtration system, just before the return of the water to the pool.

In this article we explain how to do it with a basic salt chlorinator installation scheme and the key points you should take into account to do it correctly and without complications.

Where to install a Salt Chlorinator in the pool

The Salt Chlorinator is part of the water filtration and treatment system. Its location is essential for the electrolysis principle to work properly.

The most common scheme is as follows:

Water intake → Skimmer → Pump → Filter → Filter → Salt chlorinator cell → Return to pool.

This order ensures that the water reaches the cell clean, free of particles, and that the chlorine generated is evenly distributed throughout the pool.

The cell must be placed in line with the water return, and in most installations a bypass (a valved bypass) is used to isolate it if it is to be disassembled or cleaned without stopping the entire filtration.

This design facilitates maintenance and prevents debris from passing through the cell. In the bypass, a valve regulates the water flow through the chlorinator, ensuring an adequate flow for chlorine production.

How to install a Salt Chlorinator step by step

The installation must follow the natural path of the hydraulic circuit. It is a relatively simple process, but it is important to follow the steps below to ensure proper operation:

1. Plan the location. Make sure you have enough space near the filter and a protected electrical outlet (chlorinators operate on low voltage, but require a safe electrical connection).
2. The next step is to disconnect power to the filtration system.
3. Then you will have to install the Salt chlorinator control box in a suitable location, such as near the pool filtering system and always respecting the installation and building regulations in force.
4. Cut the return pipe and install the bypass with three valves: inlet, passage to the cell and outlet.
5. Place the cell following the flow direction indicated by the manufacturer. The electrode (cell) is the part that produces the chlorine and must be installed in the pool’s return inlet respecting the flow of water returning to the pool and, if possible, making a by-pass in the connection to ensure adequate flow and that, when we want to do maintenance, the filtration can continue to operate. Make sure that the electrode is correctly Glued, fixed and connected. Also make sure that the cell is installed following the water flow rate for which it was designed. Most cells on the market have an arrow indicating the correct water flow direction.
6. Connects the control unit to the electrical system. Avoid direct exposure to sun or humidity.
7. Check connections and make sure there are no leaks before starting the system.
8. Finally, you will need to add the salt and chlorine Stabiliser to the pool so that the Salt Chlorinator can produce chlorine, then wait about 24 hours for it to completely dissolve before turning on the chlorinator.

Tips for a durable installation

• Place the chlorinator in a well-ventilated area protected from the weather.
• Keep electrical connections away from moisture.
• Check that the water flow rate through the cell matches the manufacturer’s recommended flow rate.
• If you install an automatic pH regulator or dosing pump, always locate them after the chlorinator to prevent the acid from damaging the electrodes.

Maintenance after installation

Once installed, the system requires minimal maintenance:

• Periodically check the electrolytic cell to remove scale residues.
• Check the salt and pH level from time to time.
• In winterizing, remove the cell and store it in a dry place.
