Chemigem Installation and Operation
The unit is one of the most advanced pool chemistry controllers of its kind. It is important
that it is installed and operated in accordance with the instructions provided in this manual.
The Chemigem is designed to automatically assist in keeping the levels of Chlorine and pH
correctly balanced in swimming pools and spas. It continuously monitors and adjusts pH and
Chlorine levels required through state of the art solenoid valves, utilising the natural suction
of the pool recirculating pump while the pool pump is running adds Chlorine and pool Acid as
and when required. Stable controlling of the Chlorine and pH levels of the pool water should be
achieved during the first two weeks of operation. During this period, check the level of Chlorine,
Total Alkalinity and pH regularly with a good quality test kit to confirm that the unit is keeping to
the desired levels. The chemical levels are set by the keypads. Once the correct positions have
been set for the pool water they should remain constant and do not have be changed from
season to season (however in winter the pool pump running times can be reduced)
Electronic Clock
The in-built electronic clock requires setting to your local time. To set the clock, (Refer to page
23).
Pool Pump Times
The factory-set pool pump times are on page 23. To change pumping times or to turn the timer
off,(Refer to pages 22&23).
Pool Water Circulation
To enable the Chemigem to work efficiently, the mixing of the pool water has to be as quick
and complete as possible. Positioning the return nozzles (eyeballs) to the pool so that the main
water-body rotates is the best way to achieve this. Under no circumstances should the eyeballs
be positioned to produce opposing circulation patterns. The unit’s multi-electrode (probe)
monitors the Chlorine and pH levels as the water travels towards the pump.
If the mixing of the pool water is slow, the multi-electrode (probe) will not receive the signal
until large amounts of chemicals have been added to the water. When the multi-electrode
(probe) finally receives the signal, the pool water may be overdosed and the excess warnings
will operate.
Heated Pool
If the one pool pump is required to service both the pool heating system and the Chemigem,
the pool heating plumbing must be bypassed. (Refer to pages 12&16)
