CHLORINE (SODIUM DICHLOR)

A. Sanitizing chemicals, such as chlorine, are oxidants that kill bacteria and viruses in the water. The Free Available Chlorine (FAC) is a

measure of the amount of unused chlorine available to sanitize the spa. The recommended FAC for your spa water is 3.0-5.0 ppm.

B. Watkins Manufacturing Corporation recommends the use of Hot Spring FreshWater

Concentrated Chlorinating Granuals (sodium

dichlor) for sanitizing the water. Sodium dichlor is preferred because it is totally soluble, dissolves quickly and is nearly pH neutral.

C. Maintaining the proper level of chlorine during use is extremely important.

D. If the FAC is too low, bacteria and viruses can grow rapidly in the warm water. Increase the FAC by adding granulated Sodium

Dichlor.

E. If the FAC is too high, the water can cause discomfort to the user’s eyes, lungs and skin. Simply allow some time to pass. The FAC

level will drop naturally over time.

F. When the Free Available Chlorine is within the recommended range, the spa is ready to be enjoyed.

WARNING: There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has

specific chemical characteristics. It is extremely important that the one you choose is specifically designed for use in spas. Use of

an incorrect product such as tri-chlor, which has a very low pH (2.6), dissolves too quickly in hot water resulting in extremely high

levels of chlorine, and is designed for concrete or plaster swimming pools, WILL cause damage to your spa. Use of a liquid or
