26 Usage Hours Meter The iChlor® SCG provides a built-in cell "hours used" meter that reports how many hours iChlor has been operating. The iChlor SCG is designed to operate for approximately 10,000 hours before replacement is needed or roughly five (5) years of average use. To access the usage meter through Diagnostic mode: Press and hold the MORE button for three (3) seconds until the lights scroll across the unit. The iChlor SCG will enter its diagnostic mode, showing hours of operation on the display. Cleaning the Cell Blades 1. Automatic Cleaning: The iChlor has an automatic cell blade cleaning feature that helps remove scale deposits from the iChlor blades. Note: Automatic cleaning does not interrupt chlorine production. "Scale" is a white crusty deposit that forms in excessively hard water or from pool water that is out of balance and in a scaling condition. If the iChlor blades show excessive scaling, you need to perform an acid wash cleaning. Proceed to "Acid Wash Cleaning," Step 2. Note: Before acid washing, remove the loose calcium in the cell: Use a garden hose on the jet setting and spray directly into both ends of the cell. Most of this calcium buildup has a slushy consistency and will be blown out of the cell. Once the majority of the calcium has been removed, continue with acid washing which will now be more effective since most of the calcium has been removed. 2. Acid Wash Cleaning: If the iChlor blades show a tendency to scale, it is recommended that every two (2) months the iChlor be removed and inspected for scale formation and/or debris on the iChlor blades. High hardness areas may require more frequent cleaning. Some filters allow debris to pass through to the iChlor, possibly lodging between the blades. A small amount of scale formation is normal. If by looking through the iChlor it is observed that there is excessive scale formation between the blades or debris is present, the iChlor must be cleaned as follows: a. Use a high-pressure jet of water from a garden hose. If the blades cannot be reasonably cleaned in this manner, acid cleaning is necessary. b. To acid clean the iChlor SCG blades: Turn off power to the Power Center, then disconnect the iChlor SCG from the Power Center. c. Create a 1 to 4 parts solution of acid and water. Mix one (1) quart of muriatic acid with one (1) gallon of tap water in a plastic bucket. Note: The iChlor® SCG Acid Cleaning Kit (P/N 523103) provides an acid wash stand for the iChlor SCG to allow diluted acid solution to be poured into the iChlor SCG to immerse the blades for cleaning. Working with muriatic acid can be dangerous. When cleaning the iChlor SCG always wear rubber gloves and eye protection. Always add acid to water, do not add water to acid. Always work in a well-ventilated area. Splashing or spilling acid can cause severe personal injury and/or property damage. d. Screw the acid wash stand onto the threaded end of the iChlor cell, making sure the O-ring is properly installed on the acid wash stand (acid wash stand and o-ring are provided with the acid wash kit [P/N 523103]). Place the iChlor vertically in a five (5) gallon bucket. Pour the acid solution (as described in step c) into the iChlor until the cell blades are covered. Allow the acid solution to bubble, and to clean the blades. Note: The acid should only be contained inside the iChlor covering the blades. Try not to spill the acid on the outside of the iChlor. If acid does spill on the outside of the iChlor, rinse it off with water. A foaming action will begin, which is caused by scale (calcium carbonate) being dissolved from the blades. If rigorous foaming action does not begin, the blades do not need to be cleaned (STOP THE CLEANING PROCESS - go on to step "e). Otherwise, allow the blades to remain immersed in the solution until the foaming has stopped. However, do not leave acid in the iChlor for more than thirty (30) minutes. Excessive acid washing will damage the blades. e. Remove the iChlor from the bucket and place in an empty five (5) gallon bucket. Rinse the inside and outside of the iChlor thoroughly with clean tap water and inspect. If deposits are still visible, repeat the acid cleaning process. iCHLOR® Salt Chlorine Generator Installation and User's Guide
