anced water. |

Total Alkalinity (PPM) | 120 to 150 | 120 to 150 | 80 to 120 | |
Calcium Hardness (PPM) | 200 to 300 | 150 to 200 | 200 to 400 | |
Salt (PPM) | 6000 MAXIMUM | 6000 MAXIMUM | 6000 MAXIMUM | |

*Free Chlorine MUST NOT EXCEED 5 PPM!
•Occasional chemical shock dosing of the pool or spa water should not damage the heater providing the water is balanced.
•Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water, unless controlled, they can lead to excessive chlorine level which can damage your heater, and which is not covered under warranty.
•Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical supplier for the correct levels for your water.
