Preparation
1. Turn off the UV system from the process

proceeding.
3. Turn off the main electrical disconnect. Follow
all relevant OSHA-established lockout
procedures.
4. If the lamphead has a plastic and metal
connector, disconnect the interconnect cables.
5. If necessary, loosen the lamphead mounting
fasteners and remove the assembly from the
brackets.
