Ph Control; Sanitizing - Dimension One Spas BAY Series Owner's Manual

BAY Collection
on UltraPure™ by introducing ultra violet light to the equation. Together
ozone and UV light are unstoppable. UV light comes in contact with
10,000 gallons of water per day, meticulously neutralizing any remaining
impurities. Enjoy clean, pure water and peace of mind. This system can
be found on the Bay Collection.
The UltraPure Plus Water Management System silently purifies your
water, eliminating bacteria by mixing ozone with water and emitting a
second UV light frequency that neutralizes water impurities. In order to
keep the UltraPure Plus System running at its best, it is re-commended
that you change the UV bulb every 18 months. The UltraPure Plus
UV compartment is located within the equipment bay. Contact your
authorized Dimension One Spas dealer for replacement parts and/or to
service your UltraPure Plus System.

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 hot tub 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 hot tub 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 hot tub clean is severely
affected as the pH moves beyond the ideal range. That is why almost all
hot tub water test kits contain a measure for pH as well as sanitizer.
14.3

Sanitizing

To destroy bacteria and organic compounds in the hot tub water, a
sanitizer must be used regularly. Chlorine and bromine are the two most
popular sanitizers used to date. Many other additives are available for
your hot tub. 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. When adding hot tub shock (chlorine or non-
chlorine) or pH balancing chemicals activate the jet pump(s) and leave
the hot tub cover open for a minimum of 20 minutes. By doing this you
will allow excessive chemical vapors to exit the hot tub, protecting pillows
and plastic knobs from chemical attack.
