CHECKING AND CLEANING THE FILTER The filter should be checked periodically for build-up of dirt and oil. If the filter needs to be cleaned, follow the steps below: 1. Turn off the power. Screws 2. Remove the two screws from the filter cover. Be Filter Cover careful not to strip the threads from the holes. Remove the filter Filter cover. 3. Remove the filter from the spa jet unit by lifting the filter from the filter housing. 4. Check the filter for any dirt or debris. If the filter needs to be cleaned, Filter Housing rinse the filter with a hose. If the filter is still dirty, you will need to soak it in a cleaning solution which can be obtained from a pool and spa supply store. 5. Inspect the filter for damage. Replace the filter if there are any signs of damage. maintain a slightly alkaline pH level, between 7.2 and 7.8, in the hydrotherapy spa. 6. Re-insert the cleaned filter into the filter housing. 7. Re-attach the filter cover with the screws. Do not overtighten the screws. WATER CHEMISTRY The hydrotherapy spa comes with a starter chemical pack for maintaining the water in the spa. (See TESTING AND TREATING THE WATER on page 10.) Additional chemicals can be purchased at a pool and spa supply store. CAUTION: The chemicals used to maintain the pH balance of the water and to sanitize the water can be dangerous. Always follow these basic guidelines when handling the chemicals: 1. Always read and follow the directions on the label, unless directed otherwise. 2. Never mix different chemicals. 3. Do not exceed the recommended amounts of chemicals-follow the directions on the label closely. 4. Keep all chemicals out of the reach of children and pets. 5. Keep all containers closed tightly when not in use. 6. Never add water to the chemicals-always add the chemicals to the water as directed. 7. Always store chemicals in a cool, dry place. MAINTAINING THE PROPER PH BALANCE The pH factor is a measure of relative acidity or alkalinity in the water. It is measured on a scale of 1 to 14. Pure water has a value of 7, which is neutral. Any value above 7 is alkaline, and any value below 7 is acidic. You should maintain a slightly alkaline pH level, between 7.2 and 7.8, in the hydrotherapy spa. Severe problems can occur when the pH balance is not maintained within this range. If the pH level exceeds 7.8, dissolved minerals can build-up and clog the plumbing in the spa jet unit. If the pH level falls below 7.2, the acid level in the water will begin to corrode the metal parts in the spa jet unit. Also, the sanitation agents in the water will not be effective if the pH level is not properly maintained. Damage caused by improper pH levels is not covered under the warranty. To maintain the proper pH level, you should test the pH of the water regularly. To test the water, you can either purchase additional test strips or purchase a pH test kit at a pool and spa supply store. The pH reading should be between 7.2 and 7.8. If the level is too low, add a pH increaser (usually soda ash). If the level is too high, add a pH reducer (usually sodium bisulfate). Test the water again after five minutes. See the instructions with your pH test kit for additional information about testing and adjusting the pH. 14
