14.0  Water Quality Maintenance
To decrease the risk of contracting a waterborne illness (e.g. an infection, 
bacteria or virus) and/or respiratory ailments
, m
aintain water quality within 
specied limits. This will enhance your enjoyment and prolong the life of 
the hot tub’s equipment. Doing so requires regular attention because the 
water chemistry involved is a balance of several factors. Procrastination in 
regard to water maintenance will result in poor and potentially unhealthful 
conditions for soaking and even damage to your hot tub investment. For 
specic guidance, on maintaining water quality, consult your authorized 
Jacuzzi dealer who can recommend the appropriate Jacuzzi chemical 
products. Jacuzzi chemicals are for use in the U.S. only.
WARNING: FAILURE TO MAINTAIN WATER QUALITY 
WILL: 
•  Increase risk of contracting a waterborne illness (e.g. an 
infection bacteria or virus) and/or respiratory ailments
.
•  Damage the equipment, components and spa shell, which 
are not covered under the hot tub’s warranty.
!
CAUTION: Never store hot tub chemicals inside the hot tub’s 
equipment bay. The equipment bay may reach elevated tempera-
tures, this is where high voltage electronic devices are located. This 
area is not intended for storage of any kind.
14.1  pH Control
pH is a measure of relative acidity or alkalinity of water and is measured 
on a scale of 0 to 14. The midpoint of 7 is said to be neutral, above which 
is alkaline and below which is acidic. In spa water, it is very important 
to maintain a slightly alkaline condition of 7.4 to 7.6. Problems become 
proportionately severe the further outside of this range the water gets. 
A low pH will be corrosive to metals in the spa equipment. A high pH will 
cause minerals to deposit on the interior surface (scaling). In addition, 
the ability of the sanitation agents to keep the spa clean is severely 
affected as the pH moves beyond the ideal range. That is why almost all 
spa water test kits contain a measure for pH as well as sanitizer. Jacuzzi 
offers products that help you maintain the ideal range. These chemicals 
are for use in the U.S. only.
14.2 Sanitizing
To destroy bacteria and organic compounds in the spa water, a sanitizer 
must be used regularly. Chlorine and bromine are the two most popular 
sanitizers used to date. The “Proclear Mineral Spa Clarier” designed 
especially for your hot tub is a benecial product for water maintenance. 
Many other additives are available for your spa. Some are necessary 
to compensate for out-of-balance water; some aid in cosmetic water 
treatment and others simply alter the feel or smell of the water. Your 
authorized Jacuzzi dealer can advise you on the use of these additives.
