Ph Control; Sanitizing; Other Additives - Jacuzzi J - 415 Owner's Manual

16.1

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.
16.2

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 Clarifier" designed
especially for your hot tub is a beneficial 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.
When adding spa shock (chlorine or non-chlorine) or pH balancing
chemicals activate the jet pump(s) and leave the spa cover open for a
minimum of 20 minutes. By doing this you will allow excessive chemical
vapors to exit the spa, protecting pillows and plastic knobs from chemical
attack.
WARNING:
!
OR ENTRAPMENT!
Never leave your hot tub unattended for any reason while the
cover is open and accessible, especially to small children and
animals!
CAUTION: RISK OF PERSONAL INJURY OR SPA DAMAGE!
Never add chlorine tablets (trichlor) or acid to your hot tub for
any reason! These chemicals may damage components within
your hot tub, burn or irritate your skin, create a rash and void
the manufacturer warranty for your spa.
