5. GENERAL INFORMATION:
ALGAE: Microscopic forms of plant life which enter the water by rain, wind and dust. There are nu-
merous varieties - some are free floating whilst others grow on walls and in cracks and come in dif-
ferent colours. Some are more resistant to chemical treatment than others.
BACTERIA: The germs that contaminate your water. Introduced by swimmers, dust, rain storms and
other elements.
BALANCED WATER: The correct ratio of mineral content and pH level that prevents water from
being corrosive or scale forming.
CHLORAMINES: Compounds formed when chlorine combines with nitrogen from urine, perspira-
tion, etc. Chloramines cause eye and skin irritation, as well as unpleasant odours.
CHLORINE DEMAND: The chlorine required to destroy germs, algae and other contaminants in the
water.
CHLORINE RESIDUAL: The amount of chlorine remaining after chlorine demand has been satis-
fied. This is the reading obtained with your test kit.
CYANURIC ACID: Also known as stabiliser or conditioner. It reduces dissipation of chlorine by di-
rect sunlight.
LIQUID ACID: Chemical used to reduce the pH and total alkalinity in the pool/spa water.
PPM: An abbreviation for Parts Per Million the accepted measurement of chemical concentration in
water. 1ppm = 1mg/L.

INJECTION SYSTEMS:
Before installing the Ozomatic ® , it should be decided which type of injection system will be
used:
HIGH EFFICIENCY BY-PASS INJECTOR
A high efficiency injector is plumbed around a valve to create a by-pass injector. This injector is placed in the
return line of the pool/spa and is used in situations where the maximum amount of ozone mixing is required. It
should be noted that systems with high back-pressure will defeat the operation of the venturi in this system
unless a significant reduction in water flow can be tolerated.
