Bather Load

“Bather Load” is the term used to describe the number of people using a spa, combined with the length of usage, and the frequency of usage. All these factors have a great effect on the spa water. The higher the bather load, the more chemicals need to be added and a longer filtration time will be needed.

All versions of the Cal Spas “Clear Water Plan” are designed for spas with average bather load. (3-4 people, 15 minutes of usage, 3 times a week at 100 degrees) If your bather load exceeds these guidelines, and you experience water quality problems, increase the amount of filtration first, (go to the next higher filtration number) then if water quality is still not adequate, consult the advise of your Cal Spas dealer for additional chemical or system recommendations. Be sure to give them your bather load information.

Chemical Overview

The following information is intended for use with Cal Spas chemicals only. Other brands of chemicals may have similar names and/or usage descriptions but due to manufacturing differences, use of other chemicals can increase the likelihood of under or over-dosing the spa chemicals. Damage to the spa or spa’s components from improper chemicals or chemical usage is not covered under the spa’s warranty.

Water Quality Maintenance

Chemical Safety

•Failure to follow chemical directions may result in serious injury, sickness, or even death.

•Read and follow all printed instructions listed on bottles, packages and in your owner’s manual.

•Do not exceed chemical dosages as recommended in the “Clear Water Plan”, or on chemical bottles and packages. (Most chemical instructions are figured for a 500 gallon spa however, most spas hold less than 500 gallons, consult your Owner’s Manual for the approximate gallons of your spa)

•Never mix chemicals together.

•Never change chemical brands or types without completely draining, flushing and thoroughly cleaning the spa and cover first.

•Always protect your eyes while introducing chemicals into the spa. Wear protective eyeglasses to prevent powdered chemicals from blowing into the eyes or liquid chemicals from splashing into the eyes.

•In the event of overdosing a sanitizing chemical (chlorine or bromine), immediately turn off the power to the spa and drain water to a safe and approved area. Refill with fresh water and proceed with the

“Clear Water Plan” start up.

Physical Chemical Hazards

• Do not allow chemicals to come in contact with skin, eyes or clothing.

• Always wear rubber gloves, protective eye wear and clothing to reduce the risk of chemical contact and irritation.

• Remove and wash clothing that may have been exposed to chemical contact prior to wearing them again.

• Inhaling or ingesting chemicals will cause serious injury, sickness, or even death.

• Do not mix chemicals. Mixing chemicals together can cause dangerous chemical reactions including the release of toxic gas, fire and explosions.

Chemical Storage

Chemicals must be stored completely out of the reach of children in an area that is well vented, cool, and dry. Failure to provide a proper area for chemical storage may result in serious injury, sickness, fire explosion and even death. Do not store your chemicals inside the equipment area of your spa.
