Maintaining Water Quality; Ph Control; Sanitizing; Other Additives - Imperial Winchester Owner's Manual

Maintaining the quality of the water within specified limits will serve to
enhance your enjoyment and prolong the life of your hot tub's equip-
ment. It is a fairly simple task, but it requires regular attention because
the water chemistry involved is a balance of several factors. A careless
attitude in regard to water maintenance will result in poor conditions for
soaking and even damage to your hot tub investment.
For specific guidance on maintaining water quality, contact Jacuzzi Spa
Division, who can recommend appropriate chemical products for sani-
tizing and balancing your hot tub water.
Caution: Never store hot tub chemicals inside the hot tub's
equipment bay.

pH Control

pH is a measure of the relative acidity or alkalinity of water and is mea-
sured 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 condi-
tion of 7.2 to 7.8. Problems become proportionately more severe when
this range is exceeded or diminished. A low pH will be corrosive to met-
als in the hot tub equipment. A high pH will cause minerals to deposit
(scaling) on the interior of the hot tub and equipment. In addition, the
ability of the sanitizing agents to keep the water clean is diminished as
the pH moves further outside the ideal range.

SANITIZING

To destroy bacteria and organic compounds in the hot tub water, a sani-
tizer must be used regularly. A residual sanitizer level of 1 to 3 ppm (parts
per million) is generally considered desirable.
Bromine tablets, a two-part bromine system or granular chlorine (dichlor)
are all acceptable sanitizers. IMPORTANT: Do not use chlorine tablets
(trichlor) in your hot tub. This chemical can have an extremely
corrosive effect on certain materials in the hot tub. Damage caused
by use of this chemical, or improper use of any chemical is not
covered under the hot tub's warranty. OTHER ADDITIVES
Many other additives are available for your hot tub. Some are neces-
sary to compensate for out-of-balance water, some aid in cosmetic water
treatment and others simply alter the feel or smell of the water. Jacuzzi
