ballast replacement
Ballast replacement is not part of the UV unit’s routine
maintenance. However, in the event that a ballast needs to
be replaced, the following procedure should be followed:
1. Power down the UV unit. If not, ensure that power to the
unit is removed by opening the switch or breaker
upstream of the UV unit.
2. Locate the old ballast to be replaced. Refer to the
electrical diagram, if necessary.
3. Isolate the old ballast from rest of system by disconnect-
ing the wires.
4. Using 5/32 L-shaped hex wrench completely remove
the bolt securing the ballast to the sub panel. Put the
bolt aside.
5. Remove the old ballast by pulling it towards you.
Discard the old or defective ballast.
6. Install the new ballast, securing it with the bolt
removed earlier.
7. Tighten the bolt with 5/32 L-shaped hex wrench.
8. Reconnect ballast connector(s).
9. Restore the power to the UV unit by closing the up-
stream switch or breaker.
measuring performance
Every UV treatment unit should be tested periodically to
verify actual efficiency. Regardless of the intended applica-
tion or any optional equipment which may have been
provided with your UV unit, the most accurate and depend-
able procedure is to conduct post-UV sample analysis in
accordance with standard testing methods.
Periodic sample collection and testing should be scheduled
as often as the user deems sufficient to be assured the
quality of the Aquafine ultraviolet unit effluent is accept-
able.
