CHLORINE
Standards for the amount of residual (free) chlorine in the pool water may vary from country to country, depending on
health authority regulations. Typical legal requirements are between 0.2 and 3.0 parts per million, (i.e. 0.2-3.0 milligrams
per litre).
What is understood by free or residual chlorine?
Even after the filtering process, certain bacteria remain to be destroyed by the disinfecting action of the chlorine which is
usually acting on the bacteria in the form of hypochlorous acid.
A quantity of chlorine that is added to the water (in excess of that needed to destroy bacteria and oxidize organic
material) remains free to combat new bacteria introduced by bathers or atmospheric agents.
This chlorine remaining in the water in the form of hypochlorous acid is known as free, residual chlorine.
FILTRATION
It is essential that the filtration is accompanied by chemical treatment of the pool water.
The two processes are complementary to each other.

WORKING PRINCIPLES

Water is taken from the main drains (1) on the bottom of the pool and the skimmers (2) at the pool surface and fed via
separate pipework, with their corresponding valves (3), through the pump (4) to the OC-1 filter (5).
After filtration, the water is returned to the pool via return inlets (6), which are usually installed on the opposite side of the
pool to the skimmers and main drains.
Once in the filter, the water is circulated downwards through the OC-1 media and suspended particles are retained.
The OC-1 media needs to be washed at regular intervals to remove the particles it has retained, this is known as
backwashing.
Backwashing is achieved by reversing the flow through the filter and directing the water containing the dislodged
particles to the drain.
The filter will need backwashing approx. once a month in normal domestic usage. If used in a commercial or semi
commercial environment, this should be increased to a maximum of once a week.
Bearing these principles in mind, the following installation and operation instructions should not represent any problem.
