The MegaChlor replacement electrode is only compatible with the ControlOMatic MegaChlor power supply. ControlOMatic MegaChlor replacement electrodes are specifically designed to retrofit your existing salt system on a hot tub or spa up to 1000 gallons. This replacement salt cell installs in just minutes: simply remove the 4 screws to open the ChlorMaker control box, loosen the 2 terminal post screws, and remove the old electrode. This cell is made to meet or exceed original factory specs and has 100% guaranteed compatibility.
The MegaChlor electrode simply drapes over the side of the hot tub into the water when you desire active spa sanitation, the spa doesn't even have to be on or running! The clear cell lets you see it working and allows for easy inspection.
Note: The optional inline electrode can also be installed out-of-sight directly into the existing spa plumbing when appropriate (see manufacturer recommendations).
Replacing the MegaChlor electrode will allow your salt chlorine generator to begin chlorinating again if your old MegaChlor electrode has been depleted. The MegaChlor electrode sanitizes your swimming pool in an eco-friendly and cost-efficient way, and also helps provide a luxurious swimming experience without the eye irritation and dry skin.
When replacing your MegaChlor electrode, take this opportunity to make sure it is sized correctly. Sizing your chlorine generator correctly is key to making sure you will not need to supplement with additional chlorine or shock your pool, and also extends the lifespan of your cell.The industry recommends using a salt cell with a max capacity of 1.5-2 times the actual size of your pool (more is better). The MegaChlor electrode is manufacturer rated for a maximum capacity of 12,000 gallons.
This replacement electrode for the MegaChlor is 100% compatible with original systems (no software/firmware issues). The MegaChlor electrode has the same length, threading, and cable connection for direct replacement.
To get the most life out of your chlorine generator and to keep your spa running without unexpected interruptions, make sure it is sized correctly, maintain correct water balance, and be sure and inspect your cell at least every 3 months for leaks, debris, and calcium scale. Be sure to follow instructions in the product manual and clean the cell as often as the system indicates.
