SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
OPERATION
a check valve or ball valve (see filter instructions/
recommendations). See
Diagram 3 .
NOTE : Before gluing piping or reducer bushing into
the UV’s union or socket, remove the quartz sleeve
assembly to prevent glue from dripping onto the
quartz sleeve.
NOTE : Use threaded seal tape on all threaded
connections.
Wet-Dry with External or Submersible Pump
Installation
This installation configuration shows the SMART
UV System
®
UV Sterilizer capacity matched to the
recirculating flow rate performance of the pump.
We recommend mechanical filter media being used
inside the over-flow and at the top of the wet-dry
filter.
Installing a check valve after the UV will eliminate back
siphoning. Installing true-union ball valves will allow
flow adjustments and UV removal. For best results,
install a saddle-style water flow meter, mounted
horizontally on the outlet side of the UV. Follow the
water flow meter manufacturer’s instructions for
proper installation and
operation . See Diagram 4 .

Wet-Dry w/External or Submersible Pump
Installation
This installation configuration is identical to Diagram
4 with the addition of a bypass manifold. The bypass
is used to deliver a precise water flow to the SMART
UV when the overall clean water return flow rate
exceeds the UV’s capacity.
Installing a check valve after the UV will eliminate
back siphoning. Installing true union ball valves will
allow flow adjustments and easy UV removal for
servicing. For best results, install a saddle-style water
flow meter, mounted horizontally on the outlet side of
the UV. Follow the water flow meter manufacturer’s
instructions.
