Closing Instructions
For optimal results, always follow these steps:
- Remove the solar cover.
- Clean the water line and pool surfaces.
- Adjust the pH of water to between 7.2 and 7.8 according to the instructions on the product used. pH balancing products are sold separately.
- Remove the ladder, diving board, skimmer basket and skimmer door. Do not remove the screws from the plates.
- Lower the pool water level so that it is 12 to 18 inches below the water return.
- Blow or draw all the air from the water pipes with the three-way valve handle in position 1 to close the skimmer. This position should be at the top towards the skimmer. Use of a wet/dry vacuum is recommended for in-ground pools or underground pipes. Next, block the skimmer as recommended by your pool retailer and cap the return jet with the appropriate threaded or expansion plug.
