Lamphead Repair Procedures
Preparation
1. Turn off the UV system from the process equipment controller or at the
UV panel.
2. Allow the lamphead fan to complete its cooling cycle. If this has been
prevented by premature isolation of the control cabinet, always allow
sufficient time for the bulb to cool before 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.
Bulb Replacement
1. Perform the Preparation procedure in this section.
2. See Figure 5-3. Turn or place the lamphead assembly so that the entire
bulb area is exposed and accessible.
3. Remove the eight screws from the lamphead base to remove the RF
screen.
