For UV systems the filter order MUST be as below (when looking at the system):
<----------<------ Water flow <----------<------
Polyprop Carbon Block Pleated
For Citimate systems (non UV) you can use the above configuration, or a different setup depending on your water quality. Contact us if you would like information specific to your town water supply.
Yes the UV must be switched on all the time (see exceptions below). As the globes and ballasts are sensitive to power fluctuations it is not advisable to continually switch the power to the system off and then on. When the UV is off the water flowing through the system is not being sterilised for bacteria etc.
