INSTALLATION INSTRUCTIONS
EXCAVATION
1. Excavation should be made as
close as possible to the effluent end of
the treatment plant.
2. Excavation(s) should be as minimal as
possible to reduce settling of backfill.
3. Verify the horizontal hubs of the double
sanitary tee are able to line up with the
treatment plant outlet and effluent line.
4. The UV disinfection device must be
level upon installation.
CONNECTING THE INLET & OUTLET LINES
1. Carefully unpack the UV disinfection
device. Verify all pieces are present and
in good condition.
NOTE:
The UV housing has to be installed so that
the flat edge of the keyway is on the inlet side. If
this is not installed correctly the treatment plant
effluent will not flow through the device correctly
and the UV disinfection will not be effective. See
Figure 1.
2. Clean the ends of the upstream and
downstream piping and the hubs of the
UV cross with clear plastic cleaner.
3. Connect the inlet end of the UV
housing to the upstream piping using
All-Purpose Cement.
4. Connect the outlet end of the UV
housing to the downstream piping
using All-Purpose Cement.
BACKFILLING AND RISERS
1. Once the UV housing is installed and
level, backfill up to the bottom of the
inlet and outlet hubs.
2. Fit the 4” ABS riser pipe into the
top hub of the UV housing. The
recommended riser hould not be more
than 6” above the final grade. The
riser may need to be cut to fit properly.
3. Once the riser pipe has been cut, and
both the pipe and hub have been
cleaned, glue them together using All-
Purpose Cement.
