special piping requirements
for users of ultrapure water
Ultrapure water users have reported that over time,
exposure to ultraviolet light may photochemically
degrade nonmetallic piping materials, including most
or all fluoro-polymers, resulting in material breakdown
and/or structural failure.
Should your water application and piping material be so
classified, we recommend you install “UV light traps”
to isolate any such susceptible material from direct
exposure to the ultraviolet light. One common practice
is to install stainless steel 90
o
elbows at the inlet/outlet
of the UV treatment chamber prior to the connection of
any nonmetallic materials. UV light traps protect
nonmetallic piping. Should you require any additional
assistance, please contact your local Aquafine represen-
tative or the factory directly.
wiring the unit
A

/
2
” conduit knockout (
7
/

” dia.) has been provided to
attach a field installed junction box. This box should be
directly attached to the enclosure. All wiring connec-
tions must be made within this junction box. The size
and type of junction box should be made in accordance
with local and applicable codes.
GROUNDING
IT IS IMPERATIVE THAT THE UNIT BE
PROPERLY GROUNDED FOR SAFE AND PROPER
OPERATION.
Failure to properly ground the UV treatment unit
automatically voids all equipment warranty.
UV performance is line voltage sensitive. Line voltage
should be +5% of rating shown on the electrical
nameplate decal. Voltage outside these limits can reduce
the performance of the UV unit.
All supply connections are to be made in a UL-listed
junction box suitable for the number and size of conduc-
tors. The instructions shall also specify that the junction
box is to be directly attached to the unit.
