6.0 MAINTENANCE
6.1 It is recommended that a pool water sample is taken to a pool shop and tested once per 
month for analysis. Please refer to Section 2.0 for additional information.
6.2 The electrolytic cell operates most efficiently when it is clean. As a natural result of the 
electrolytic process, which creates chlorine from salt molecules, calcium is attracted to 
the titanium plates in the cell. The self-cleaning feature helps to inhibit such build-up 
and scaling. However, the attraction of calcium and other minerals is inevitable, and 
eventually, it must be removed.
6.3 The transparent housing of the cell allows easy visual inspections, and with correct 
water chemistry, the cell will only need cleaning approximately every 3-6 months. In 
regions with hard water (high calcium levels), more frequent cleaning may be required.
6.4 To clean the cell follow these instructions:
1. Turn off power to the chlorinator and pump.
2. Remove the cell from the cell housing by loosening the cell collar and pulling the 
cell out of the housing. If required, disconnect the cell cable wires at the junction box 
underneath the power pack (these must be reconnected firmly and tightly).
3. With the cell removed, use a high-pressure hose nozzle to spray off as much loose 
scale as possible. Do not use any sharp or metallic objects to remove scale, as this will 
damage the cell. 
4. If further cleaning is required, the cell needs to be cleaned in a mixture of 1 part 
Hydrochloric Acid to 10 parts water. Mix the acid solution in a bucket or tube that will 
fit the cell.
5. iWARNING: Chemical Hazard - When mixing acid with water, always add the acid 
to the water, never add water to the acid. When using the acid, ensure to use rubber 
gloves and appropriate eye protection and follow safety directions on the Hydrochloric 
Acid label.
6. Place the cell into the cleaning solution submerging the plates and ensuring that the 
cell head (Section 3.0 Fig. 2) does not contact the acid solution. Once the cell is clean, 
remove it from the cleaning solution and rinse. Replace the cell into the housing in the 
reverse manner to the steps above.
6.5 Only qualified electrical technicians should service the power pack. For the nearest
