How to Install a Salt Chlorinator (Step-by-Step Guide for South Africa 2026)
Installing a salt chlorinator might sound technical—but in reality, it’s straightforward if you follow the right steps.
We have seen many installations go wrong, not because the system is complex, but because small details are missed—like incorrect placement, poor flow setup, or choosing the wrong size unit.
The result?
👉 Poor chlorine production
👉 System issues
👉 Frustrating pool problems
The good news is:
👉 You can install a salt chlorinator correctly the first time
In this guide, we will walk you through:
- Where to install your chlorinator
- Step-by-step setup
- Common mistakes to avoid
BEFORE YOU START (IMPORTANT)
Before installing your system, make sure:
👉 You’ve chosen the correct size chlorinator
This is critical.
If the system is too small, it won’t produce enough chlorine—no matter how well it’s installed.

WHAT YOU’LL NEED
Basic tools and setup:
- PVC piping and fittings
- Glue and primer
- Screwdriver
- Power supply access
- Pump and filtration system
WHERE TO INSTALL YOUR SALT CHLORINATOR
Placement is one of the most important factors.
✅ Correct Position:
👉 AFTER the filter
👉 BEFORE water returns to the pool
Why this matters:
- Clean water passes through the chlorinator
- Improves efficiency
- Prevents damage to the system
❌ Incorrect placement:
- Before the filter
- Before the pump
- In low-flow areas
👉 If installed incorrectly, your system will underperform
STEP-BY-STEP INSTALLATION GUIDE
STEP 1: TURN OFF YOUR SYSTEM
Before starting:
- Switch off pump
- Shut down power supply
👉 Safety first
STEP 2: CUT INTO THE RETURN LINE
Identify the return pipe (from filter to pool).
Cut a section where the chlorinator cell will be installed.
STEP 3: INSTALL THE CELL HOUSING
Fit the chlorinator cell into the pipe:
- Use correct connectors
- Ensure flow direction matches arrows
- Seal properly with PVC glue
👉 Proper sealing prevents leaks and performance issues
STEP 4: CONNECT THE CONTROL UNIT
Mount the control unit:
- In a dry, shaded area
- Close to power source
- Accessible for monitoring
STEP 5: CONNECT POWER
Wire the unit according to instructions.
👉 If unsure, use a qualified electrician
STEP 6: RESTORE WATER FLOW
Turn your pump back on and:
- Check for leaks
- Ensure proper flow
- Confirm system operation
STEP 7: ADD SALT TO YOUR POOL
Add the correct amount of salt based on your pool size.
👉 Too little salt → low chlorine
👉 Too much salt → system stress
COMMON INSTALLATION MISTAKES (AVOID THESE)
❌ Installing Before the Filter
👉 Leads to dirty water entering the cell
👉 Reduces lifespan
❌ Incorrect Flow Direction
👉 Reduces efficiency
👉 Can damage the system
❌ Poor Sealing
👉 Causes leaks
👉 Affects pressure and performance
❌ Wrong Chlorinator Size
👉 The biggest mistake of all
👉 Fix this here
