Jacuzzi J-345 Manuel D’Utilisation

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 pH. 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 the sanitizer.

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 jets 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.

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.
