Under Salt Condition: In the event of Low Salt concentrations, or readings under the 100%
mark on the Output Meter in Salt Test Mode, it is advisable to turn the Chlorinator OFF until
the salt levels have been increased. Failure to rectify the low salt levels will result in the unit
underperforming and prematurely destroying the electrode.
An analogy can be drawn to a motor vehicle operating on low oil levels. Failure is imminent if
not resolved immediately.
NOTE
:
Too little salt will result in premature element failure - this is a Non-Warranty issue.
14. Shock Treatment
NOTE: It is safe to supplement the chlorinator with granular chlorine. No harm will be done to
the chlorinator, or its electrode, as long as the chlorine is dissolved in a bucket of water before
application.
Before turning the chlorinator ON, (after all the salt has be dissolved), the level of free
available chlorine of the pool water must be no less than 1.5ppm at the onset, the chlorinator
will not
raise the chlorine reading from 0ppm to 1.5ppm in the time period that is required
before the pool turns a shade of green. The chlorinators’ purpose is to produce chlorine on a
consistent daily basis, thus eliminating the need for you as the individual to perform this
tedious task.
If needed, one should add dissolved granular chlorine into the pool to achieve the desire start
point. Utilise the Standard Pool Test Kit (4-in-1), to test for chlorine levels. Shock treatment
with granular chlorine can be carried out after heavy rain showers, or excessively high
temperatures, or high bather loads. This should be utilized as a last resort if the chlorinator is
unable to cope with these varying demands.
15. Mechanical Equipment
Your pump and filter are an integral part of your waters clarity and chlorinators operation.
Without an effective clean filter you will encounter many difficulties with your water. Like wise,
if the pump is defective you too will have difficulties.
Most pools have some form of “automatic” pool cleaner. These units are very cleverly
designed pieces of “plastic” and they all work well. They require energy to drive them and this
energy is derived from the pool pump whose suctioning ability is determined largely by the
condition of the filter, cleanliness of the weir basket and pump suction basket cleanliness.
NOTE: Garden debris entering the pool system generally passes through the filtration system,
all of which affects the overall performance of the pool, including the water chemistry.
Remember, all the water passes through the filter at a rate of ~ 15 000 litres per hour, for 7
days, 12 hours a day.
15.1. Backwashing
To minimise salt and chemical loss during backwashing, insert a garden hose into the
skimmer box and leave the hose turned “on” whilst backwashing. This predominately allows
the fresh tap water to backwash the filter, as opposed to the chemical containing pool water.
When backwashing, it is advisable to turn the chlorinator - OFF. Remember to turn in ON
again when you have finished.
