CHLORINE
Chlorine is a water sanitizer also, however it is more sensitive to pH than bromine. To be effective, you
must have a pH range of 7.2-7.6. Any reading outside this range will greatly reduce chlorine
effectiveness.
Use a chlorine test kit or test strip to maintain a reading of 2.0-3.0 ppm of free chlorine. If the reading is
below the minimum, raise the level before using the spa. If the reading is above 5.0 ppm, allow ppm to
drop to the proper range before using the spa. Read the instructions on your chlorine container
carefully, or consult your local L.A. Spas dealer if you are having difficulty adjusting your chlorine level.
The best chlorine for your spa is a granular “Dichlor” compound. It dissolves quickly in moving water
and has a nearly neutral pH. Add chlorine while jets are running and let the jets run for ½ hour.
Generally, heavily contaminated water can be disinfected using large chlorine doses, in the range of 8-
10 ppm, but a more practical method is to drain the spa and refill it with fresh water.
The effectiveness of chlorine is decreased when the cover is left off the water for two reasons: (1)
sunlight decays chlorine rapidly, and (2) organic debris is blown into the spa and taxes the effectiveness
of the chlorine. In addition, the higher the water temperature, the faster chlorine will decay.
NOTE: Two or more individuals in a spa may reduce the level of sanitizer rapidly.
SUPER CHLORINATION
Super chlorination quickly oxidizes the spa water to burn out wastes such as perspiration, hairspray,
lotions, etc. that cannot be removed by the spa filter. This waste build-up reduces the power of the
sanitizer, making the water dull and irritating to the eyes and skin. It may also produce an odor. When
this occurs, the free chlorines have become chloramines which are much less effective as a sanitizer.
This can be eliminated by super chlorination as needed. An application of 5 times the normal chlorine
dosage will act as an adequate treatment.
SHOCK TREATMENTS (POTASSIUM PEROXYMONOSULFATE)
Even with regular sanitization, shock treatment may be necessary on occasion. Shock is recommended
over super chlorination because it does not add additional sanitizer to the water. It is also effective in
oxidizing wastes and will reduce chloramines or bromamines. Follow the manufacturer’s instructions
listed on the label.
OZONE
Your spa maybe equipped with an ozone generator. L.A. Spas requires that only their ozone generator
be used on spas due to the design of the mixing chamber system. Ozone related failures due to use of
other manufacturer’s ozone generators will not be covered under warranty. On spas equipped with
UWMS, ozone delivery occurs when the circulation pump is running. On spas without UWMS, ozone
delivery occurs any time the low speed of pump #1 engages or operates either during a heat cycle or
filter cycle.
WATER TESTING
It is recommended that you test your spa water regularly with an accurate test kit or test strip. These are
available from your local authorized L.A. Spas dealer. Be sure to follow the chemical manufacturer’s
instructions for chemical use.
