System Sizing
All RainHarvest Systems UV systems are rated for a specic ow rate in water that meets
the quality parameters on page 5. PLEASE NOTE that increasing the ow above this rang
or disinfecng water that does not meet the quality parameters will decrease the dose and
therefore compromise the microorganism inacvaon.
If you need to determine your maximum ow rate, you can ll a 1 gallon bucket with water and
me how long it takes to ll up. It is always beer to oversize your system then to undersize. For
example, if your pump delivers 8 gpm it is recommended to install any of the 10 gpm systems.
Locaon
For Point of Entry (POE) systems, choose a locaon where the main cold water line is accessible.
The system must be installed aer other water treatment equipment (soener or lters), but
before any branches (See Figure 1). For Point of Use (POU) systems, install the unit just before
the faucet. RainHarvest Systems recommends that a 5 micron lter be installed before the UV
system for a nal polishing step before the water is disinfected.
Figure 1. Recommended POE Installaon Locaon
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 RainHarvest Systems UV disinfecon systems are intended for indoor use only
as they should not be exposed to the elements.
