***** USE CARE AS YOU MAY BE USING MURIATIC ACID *******
--->>> DO NOT USE ANYTHING SHARP OR INSERT ANYTHING BETWEEN THE CELL BLADES THAT MAY SCRAPE THE BLADES AS YOU WILL COMPROMISE THE CELL LIFE AND MAY VOID WARRANTY!
1) Read the above warnings!
2) Turn the pump off.
3) Disconnect the cell cord.
4) Remove the cell from the manifold and using a high pressure hose nozzle, spray off as much debris as you can.
5) You can use a 1.5" clean-out-plug, a tall bucket, or the manifold to cover the cell blades with an acid solution.
- If using the manifold, remove thee upper portion of the manifold from the base (remove the tri-sensor cord and cap off the connector), then turn it upside down so that it's like a "U".
- If using a clean-out-plug, it may allow some solution to leak or drip, so be careful where you place it and how you handle it.
6) Mix a solution of 1 part muriatic acid added to 4 parts water. DO NOT ADD THE WATER TO THE ACID, as a chemical reaction may occur where the acid can splash on you.
7) Add enough solution to complete cover the cell blades. There will be an effervesence action that will bubble up and may bubble over the cell, so be careful where you place the cell.
8) Set the cell sit more more than 20 minutes or until the bubbling stops.
9) Pour the acid solution out and dilute it for safety.
10) Inspect the cell for scale and repeat from step 6 if there is still scale.
11) Once completely clean, dry off the cell terminals thoroughly.
12) Replace the cell/manifold and reconnect the cord(s).
13) Turn the system back on and inspect for leaks.
14) Determine WHY the cell scaled up.
The Rule of Thumb is this:
If the cell scales up in a week or less, it's usually due to the unit not reversing polarity properly.
If the cell scales up in two weeks or more, it's usually due to a water chemistry imbalance, according to the Saturation Index or Taylor Watergram.
Hope this helps.
