Routine Maintenance
Replacing the Bulbs
WARNING
Hazardous Vapors!
If large numbers of UV bulbs are broken, an appropriate respirator should be considered to
prevent inhalation of mercury vapors. Failure to use a respirator could result in death or serious
injury.
CAUTION
Broken Glass!
Bulbs are fragile and can be easily broken. Always use gloves and eye protection when handling
these bulbs. Failure to handle bulbs properly may result in minor to moderate injury. Refer to the
MSDS sheet from the bulb manufacturer for additional safety information.
Ultraviolet bulbs should be replaced annually if operated continuously or after 9,000 hours of use
if operated intermittently. Replacement bulbs must be the specific size and wattage as originally
supplied from the factory.
Note:
Although the lights may continue to generate a characteristic blue glow beyond 9,000
operating hours, the ultraviolet radiation emitted by the bulbs degrades over time and will
no longer provide the intended benefit.
1.
Disconnect power to the HVAC unit and the ultraviolet bulbs. SEE WARNING ABOVE.
2. Wearing soft cloth gloves and safety glasses, use two hands and firmly grasp the bulb at each
end.
3. Rotate the bulb 90 degrees in either direction and move bulb away from the fixture and out of
unit.
4. Carefully install a new replacement bulb in the fixture and rotate it 90 degrees in either direction
until it is firmly secured.
5. If broken bulbs are found or if you are required to dispose of used bulbs, the proper warning
and cautions must be followed.
6. Always use cloth gloves and suitable eye protection when cleaning or replacing these bulbs.
Bulbs may break if dropped or handled improperly.
Disposal of Bulbs
UV bulbs, like fluorescent bulbs, contain mercury, which is a regulated hazardous waste. The
disposal requirements for hazardous wastes are determined by local, state and federal guidelines.
Check all regulations before disposing of bulbs to assure you have met all requirements.
Refer to the MSDS sheet from the bulb manufacturer for additional disposal, handling and safety
information.
After replacing bulbs, close and latch all unit panels and reenergize power to the lights.
