This ceel is a standard replacement cell. It features 7 solid plates increasing its lifetime. Plates are 146mm in length and are good for 18 amps.
To clean the cell switch off the chlorinator and remove the cell from the housing following manufacturer instructions. If the scale layer is not very heavy the deposits can be washed away with a garden hose however do not brush the electrodes or scrape with sharp objects. If the above does not help, it is needed to soak the cell in suitable cleaning solution like Salt Chlorinator Cleaner or self mixed acid solution. To prepare acid solution mix 1 part of Pool Acid (Hydrochloric Acid) with 5 parts of water in the bucket. Submerge the cell into the solution for 3-5 minutes. If it takes longer than 5 minutes to clean the cell it is an indication that the electrodes should be cleaned more frequently. Then just put the cell back into cell housing.
