SMART UV® UV DISINFECTION STERILIZER Installation and User's Guide
OPERATION
SMART UV
®
Installation and Operation
SMART UV Systems UV Sterilizers are used in
a variety of applications to control waterborne
pathogens. Pentair encourages the consideration of
the installation/operation recommendations provided
here.
Suspended solid waste will absorb UV light and
reduce the UV transmittance through water. By
operating the SMART UV after the mechanical filter,
the unit’s overall performance will be increased.
When operating SMART UV sterilizers please
consider the recommended water flow rates.
Pond Installation Configurations
Small to Moderately Sized Ponds (up to 5,000
Gallons) Using Skimmers and Falls
Placing the UV between the skimmer box and the
filter ensures that pre-filtered water reaches the
UV, increasing its performance while reducing
maintenance.
Often the capacity of the pump exceeds the capacity
of the UV. If this is the case, install a bypass manifold.
Be sure that the skimmer is equipped with mechanical
filtering capacity. See
Diagram 1
.
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.
Larger Sized Ponds (above 5,000 Gallons) Using
Surface Skimmer and Pressurized Filter
This system is simple yet it achieves critical filtering
goals, such as good water circulation for increased
solid waste suspension. The bottom drain/surface
skimming capabilities ensure maximum waste
removal. See
Diagram 2
.
The SMART UV System UV Sterilizer is positioned
after the mechanical filter where it can receive only
solid waste free water, optimizing UV transmittance/
performance. Notice the 3-way valve that regulates
suction from the skimmer and drain to the pump,
allowing flow control.
Next, multiple “clean water returns” improve
circulation, suspending solid waste and helping it to
find the filter. If you have a flow rate that exceeds the
UV’s, install a by-pass manifold. See
Diagram 1
.
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.
Aquarium Installation Configurations
Canister Filter/Aquarium Installation
Pressurized Canister filters are commonly used with
small freshwater/saltwater aquariums.
Diagram 3
shows a SMART UV model.
It is important to match the Canister Filter’s flow rate
to the capacity of the SMART UV. If this is not feasible,
use a bypass manifold (see
Diagram 5
on page
14). To prevent back-siphoning, consider installing
