WATER CHEMISTRY

The hydrotherapy spa comes with a starter chemical pack for maintaining the water in the spa. (See TEST- ING AND TREATING THE WATER on page 11.) 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 guide- lines when handling the chemicals:

1.Always read and follow the directions on the label, unless directed to do otherwise.

2.Never mix different chemicals.

3.Do not exceed the recommended amounts of chemicalsÑfollow the directions on the label closely.

4.Keep all chemicals out of the reach of chil- dren and pets.

5.Keep all containers closed tightly when not in use.

6.Never add water to the chemicalsÑalways 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 alka- linity 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 RENEW 207.

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 cor- rode the metal parts in the spa jet unit. Also, the sani- tation 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, test the pH of the water regularly. You will need a pH test kit (not includ- ed), which can be obtained 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.

REMOVING AND ATTACHING THE ACCESS COVER

To remove the access cover, first remove the four access cover screws. Slide the access cover down and then pull the bottom of it away from the spa unit.

Be careful not to damage the spa shell as you remove the cover.

If the spa will be stored for any period of time, place the power cord inside the spa unit before re-attaching the access cover.

To reattach the access cover, insert the top of the cover under the edge of the spa shell. Slide the cover up until the bottom of the cover clears the trim along the bottom of the spa unit. Slide the cover into place and re-attach it with the two access cover screws.

DRAINING THE RENEW 207

The RENEW 207 should be drained at least four times a year and refilled with clean water. You may need to drain the spa more often, depending on the user load. This must be done, because after repeated chemical treatment, the water becomes chemically saturated. Once this happens, additional chemical treatment of the water is no longer effective. The spa should also be drained if it will not be used for long periods of time. The spa must always be drained before major repairs are made.

The RENEW 207 should always be covered when it is empty. Direct sunlight can cause extensive damage. The surface of the spa shell can reach temperatures as high as 150¡ F in a matter of min- utes if exposed to the sun while it is empty. These high temperatures can cause significant damage, such as blistering of the shell surface and warp- ing of the spa shell. Any damage caused by sun exposure is not covered under warranty.
