WATER CHEMISTRY
Maintaining the pH level of the water is very important to the operation of the spa. To maintain the proper pH level and to sanitize the spa, you can purchase a chemical starter kit from your local pool and spa sup- ply 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 otherwise.
2.Never mix different chemicals.
3.Do not exceed the recommended amounts of
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
7.Always store chemicals in a cool, dry place.
MAINTAINING THE PROPER PH BALANCE
The pH factor is a measure of the relative acidity or alkalinity in the water, and 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 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. To test the water, 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 infor- mation about testing and adjusting the pH.
SANITIZING THE HYDROTHERAPY SPA
The most common sanitizing agent is a solid bromine concentrate. The amount required varies according to several factors, such as user load, temperature, and water conditions. Proper water maintenance is a com- plex process. Contact your local pool and spa supplier for information concerning which chemicals you should use in your area to sanitize the spa.
CHANGING THE FILTER CYCLE
The spa will filter the water every 12 hours. The dura- tion of the cycle can be adjusted to last 2, 4, 6, or 8 hours or run indefinitely. Press the temperature up or down button on the console. When the display begins to flash, press pump button 1. The display will read “F2.” To change the time, press the temp up button until the desired time is reached. Press pump button 2 to confirm the selection.
Pump 2 purges for five minutes and the blower purges for 30 seconds at the beginning of each filter cycle. Pump 1 will run on low during filtration and the ozone generator will be enabled.
As spa usage increases, the duration of the filter cycle may need to be increased.
