System Sizing
All PURETEC UV systems are rated for a specific flow rate in water that meets the quality param-
eters on page 5.
PLEASE NOTE
that increasing the flow above this rating or disinfecting water
that does not meet the quality parameters will decrease the dose and therefore compromise the
microorganism inactivation.
If you need to determine your maximum flow rate, you can fill a 1 gallon bucket with water and
time how long it takes to fill up. It is always better to oversize your system then to undersize. For
example, if your pump delivers 8 gpm it is recommended to install any of the PURETEC 10 gpm
systems.
Location
For Point of Entry (POE) systems, choose a location where the main cold water line is accessible.
The system must be installed after other water treatment equipment (softener or filters), but
before any branches (See Figure 1). For Point of Use (POU) systems, install the unit just before
the faucet. PURETEC recommends that a 5 micron filter be installed
before
the UV system for a
final polishing step before the water is disinfected.
Figure 1. Recommended POE Installation Location
To facilitate lamp removal, ensure there is enough space at the lamp connector end to safely
remove the UV lamp and/or quartz sleeve (See Figure 2).
The controller will require a ground fault circuit interrupter (GFCI or GFI) outlet and should be
mounted beside or above the reactor.
PLEASE NOTE: All PURETEC UV disinfection systems are intended for indoor use only as they
should not be exposed to the elements.
