Add salt to the pool water. The amount of salt depends on how many gallons of water the pool holds. Find the amount of gallons held by the pool by either the pool's owner manual or by taking pool measurements. For an existing pool that's been using chemical chlorine, check current salt levels with an electronic meter or test strips before adding more. If the pool gets over-salted, water must be drained.
Secure the salt generator cell on the pool pump wall using a drill and screws and mounting brackets included with the system's parts. Leave room to mount the control box next to the cell. The cell's wire leads should be pointed down or towards the location of the control box. Some cells may be mounted either vertically or horizontally other are required to be mounted in a specific direction.
Drill holes in three separate places, into the pool pumps return line, the PVC plumbing between the pump and the pool filer and after the filter for the system's bypass hoses to be placed. Measure and cut each hose length needed for the three bypass areas.
Attach hoses with metal clamps included with the system's materials. There may be a significant amount of PVC plumbing required depending on how the pool pump equipment is situated.
Mount the control box. Wire in the power supply to the control box. Connect the cell's wire leads to the box. Know if the system is designed to control the pool pump or if it turns on with the pump. An automatic control system usually supplies power.
