Cleaning the cell
The cell should be checked periodically for calcium deposit. In order to eliminate the calcium, the cell should be removed
from the robot (Fig. 1-4). Calcium can be easily removed with water pressure and using hand cleaning.
If the calcium deposit is excessive, the cell should be placed into a cup of diluted muriatic acid or regular strength white vinegar.
ALWAYS ADD ACID TO WATER and not the other way around.
1. Take a large cup and fill it 60% with water (Fig. 5).
2. Add acid until the cup is 75% full (Fig. 5). Be sure not to fill the cup too high to prevent overflow when cell will be inserted.
WARNING: Always wear Latex gloves and eye protection when handling acid!
WARNING: Always add acid to water. DO NOT add water to acid!
3. Insert the cell into the solution (Fig. 6).
WARNING: DISCONNECT the cable from the cell! Cleaning procedure has to be done with the cell disconnected.
4. Wait for the solution to stop bubbling (20 mins).
5. Rinse cell with fresh water and insert back into the robot (Fig. 8).
