10. The water purifier should be located after all other water devices, such as De-ionizers, Water Softeners, Carbon Filters, Pre-
Filters, Reverse Osmosis, Pressure Tanks, and Pumps. This reduces the chance of the purified water being re-contaminated by
bacteria in any of these units.
11. Flow direction - water enters the unit through the lower fitting and exits through the upper fitting. The flow control is
mounted in the lower (inlet) fitting.
12. Installation requires a 5-micron sediment filter be installed, in line, prior to the water purifier. The sediment filter will stop or
trap any particulates from entering the water purifier. Particulates may cause deposit on the quartz sleeve as well as interfere
with the purifier's ability to disinfect the water. The sediment filter may also help to reduce the amount of routine cleaning of
the quartz sleeve.
13. Shut off valves and unions should be installed on both the inlet and outlet sides of the water purifier. The use of bypass valves
is not recommended. The shut off valves allow the purifier to be isolated from the water supply, which is required when
removing the quartz sleeve.
