It is suggested that swimming pool water should be maintained within the following ranges
and that these ranges are confirmed with your local authorities as meeting their standards:
CHLORINE 1.0 to 3.0 ppm or 3.0 mg/l •
pH 7.2 to 7.8 •
CALCIUM HARDNESS 90 to 300 ppm or 300 mg/l •
STABILISER 30 to 50 ppm or 50 mg/l •
TOTAL ALKALINITY 80 to 300 ppm or 300 mg/l •
TOTAL DlSSOLVED SOLlDS (TDS) 300 to 1500 ppm or1500 mg/l •
Pay particular attention to the instructions on the chemical drums. Add each chemical
separately and slowly allowing plenty of time for them to dissolve. Always test between
additions with a good quality test kit.
When diluting chemicals always add the concentrated chemical substance to the water and
never add the water to the concentrated chemical. Some chemicals react violently with water
and can splash into the face and eyes. Always wear a protective face shield and gloves for
such operations.
After the pool water has been correctly balanced and the unit is switched on, it will measure
and automatically adjust the Chlorine and pH levels. Chlorine and pool Acid will feed
separately for a few seconds approximately every 3 minutes until the required levels are
reached - depending on how the unit has been programmed.
ELECTRONIC CLOCK
The Chemigem has an in-built electronic clock with a battery back up (which should last for
several years) that controls the automatic switching on and off of the pool pump.
DOSING OF CHEMICALS
Dosing of chemicals will only commence after a few minutes to allow for adequate mixing and
accurate sensing. Similarly the safety warning sounds and alarm signals will not operate for
the first 5 minutes. Every 3 minutes Chlorine will feed for 8 seconds and then pool Acid will
feed separately for 7 seconds, until the required chemical levels are reached - depending on
how the unit has been programmed.
Depending upon how the unit has been programmed, the standard procedure is that the
first time that the unit operates it will take approximately 120 minutes to fully adjust to the
required levels of Chlorine and pH. Thereafter it will normally restore the required levels in
approximately 30 minutes. Ensure that the pool pump is running for a sufficient period to carry
out these adjustments.
THE FIRST TWO WEEKS
The day following the installation of the Chemigem and after the pool pump has been running
for 30 minutes, check the level of Chlorine and pH with a good quality test kit. If either of the
levels is not exactly at the levels required, alter the settings a little. The unit will bring about
the changes to the chemistry of the pool water as the pool pump circulates the water.
During the two weeks after a pool is first filled, the water chemistry will be settling down.
It is likely that chemical levels will fluctuate during this time, so keep a check on the pool
water with a good quality test kit or obtain confirmation by seeking help from a qualified pool
maintenance technician.
