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 by turning the unit isolator

switch, if installed, to the “OFF” position. 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 disconnecting

the ballast connector.

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 turning the unit

isolator switch to the “ON” position or by closing the

upstream switch or breaker.
