POOL PHOTOMETRIC WATER ANALYSIS PL25 Testing the Pool Lab Chlorinator
TROUBLESHOOTING GUIDE – HOW TO CHECK IF THE CHLORINATOR IS WORKING
IMPORTANT – SALT LEVEL MUST BE AT LEAST 3000PPM TO PERFORM THIS TEST.
Pool Lab salt chlorinators regulate chlorine output by switching power to the
cell ON and OFF over a 3-minute cycle. When monitoring the cell output it is
normal for the output to switch off for up to half of this 3-minute cycle.
Higher water temperatures and higher salt levels will increase the amount of
time the cell power is OFF for. Pool Lab chlorinator cells have two
polarities: + and -. The following procedure will test the chlorine production
by measuring the amps drawn by the chlorinator cell in each polarity.
-
Switch the power to the Pool Lab salt chlorinator off at the power outlet and wait at least 10 seconds.
-
If there is a Pool Lab ASP (Auto Sampling Photometer) connected, unplug it from the port at the bottom of the power pack.
NOTE: Make sure to keep the connector clean and dry during the test procedure. -
Switch the power to the Pool Lab salt chlorinator ON at the power outlet.
-
Using the MODE button, select manual ON mode. The filtration pump should now be running.
NOTE: If the filtration pump is controlled by a third-party controller, ensure the pump is running. -
If the display does not show “CL SET: 100%” use the UP button to increase the chlorinator output to 100%. Press VIEW to save the setting. The screen should look like this:
-
Hold the BACK button until the DIAGNOSTIC VIEW appear. This view shows the power supply voltage available to the cell, the cell amp draw, and the polarity + or -. The screen should look like this:
-
When the cell current has stabilized (after approx. 15-30 seconds from selecting ON mode), record the VOLTS and AMPS readings as well as the + or – polarity indicator.
-
Press and hold the VIEW button until the letter “R” appears over the polarity indicator. This indicates a polarity reversal is in progress. The screen should look like this:
Once polarity reversal is complete, the polarity indicator should now be showing the opposite polarity to what was recorded in Step 7. -
Wait 15-30 seconds for the cell current to stabilize and record the VOLTS and AMPS and the polarity.
-
Push the BACK button to return to the HOME VIEW. Use the MODE button to reset the filtration mode to its previous value – usually AUTO when the pump is controlled by Pool Lab.
-
If no ASP was connected, use the UP/DOWN buttons to reset CL SET to its previous value, and press VIEW to save the setting. If an ASP was connected, switch power to the Pool Lab salt chlorinator OFF at the power outlet and reconnect the ASP to the socket marked “ASP” on the bottom of the chlorinator power pack. Then turn the power back on.
-
Compare the recorded VOLTS and AMPS values with the table below.
Model| VOLTS| AMPS (+)| AMPS (-)| **Max Difference
(+/-)*| Min. Ideal AMPS****
---|---|---|---|---|---
PL25, ML25, PLECO| 23 – 26 V| 3.2 – 8.2| 3.2 – 8.2| + 0.8| 4.2
PL35, ML35| 23 – 26 V| 4.4 – 13.2| 4.4 – 13.2| + 1.3| 5.9
PL45, ML45| 23 – 26 V| 5.7 – 13.2| 5.7 – 13.2| + 1.3| 7.5
-
The + and – polarity of the cell should have a similar amp draw, within approx. 10%
** This is the minimum current required for each model to produce the rated chlorine output- VOLTS – The voltage should always be in the range of 23V – 26V. Outside of this range may indicate a faulty power supply.
- AMPS – Amp draws within range on both polarities, and <10% difference. Your chlorinator is working.
- AMPS – Amp draw on one polarity significantly different from the opposite polarity may indicate a faulty or calcified cell***.
- AMPS – Amp draw low on both polarities may indicate a calcified cell*** or low salt level.
- AMPS – Amp draw exceeds the maximum indicating that the salt level is too high.
- AMPS – No amp draw on one or both polarities may indicate a faulty cell or a fault with the chlorinator power pack***.
*** Clean the cell with diluted acid as per instructions in the owner’s manual
and repeat the test. You must perform this step even if the cell appears to be
clean, as there can be a clear insulating layer that is not visible. If
cleaning the cell does not rectify the issue then there may be an issue with
your chlorinator cell or power pack. If your chlorinator is working but you
are still having issues with low chlorine, contact your local pool
professional for assistance with high chlorine demand and/or refer to the FAQ
– Chlorine Testing Low section on our website.
