The UV-Ionizer has to be integrated into the filter cycle of the swimming pool, a dry technique area would be best. The water entrance of the UV-ionizer is in the upper right hand corner and has to be connected with the piping, which comes from the pressure site of the filter. The exit, at the bottom left hand corner, has to be connected with the line, which leads back into the pool. Additional external pH-dosage-systems, heat exchangers or other technical equipments should be installed after the UV-Ionizer. Put in the plug and the system is ready to run.
