6.
Take out the 4 lamps by pulling it forward from the holder.
7.
Clean the lamps with a soft, lint-free cloth.
8.
Clean the reflectors with a soft, lint-free cloth. For reflectors, the cloth may be moistened with pure alcohol.
9.
Place the lamp back into the lamp holders. If replacing lamp, place new lamp into position. Lamps contain mercury.
Replaced old lamps should be disposed properly!
10. Re position the white plate and place the capped nuts back into position. Tighten the capped nuts.
11. Leave the area of the UV-C beam and stay in the freely accessible zone as defined by the visible marking safeguard.
12. Remove the lockout tagout from the switch at the central switch location
13. Turn on power
14. Repeat the commissioning process to make sure that after lamp replacement, the irradiance levels are still acceptable
In case of lamp breakage follow below instruction:
Before Cleanup:
•
Have people and pets leave the room and avoid the breakage area on the way out.
•
Open a window or door to the outdoors and leave the room for 5-10 minutes.
•
Shut off the central forced-air heating/air conditioning (HVAC) system if you have one.
•
Collect materials you will need to clean up the broken bulb:
Stiff paper or cardboard
•
Sticky tape (e.g., duct tape)
•
Damp paper towels or disposable wet wipes (for hard surfaces)
•
•
Glass jar with a metal lid (such as a canning jar) or a sealable plastic bag(s)
Cleanup Steps for Hard Surfaces
1.
Carefully scoop up glass fragments and powder using stiff paper or cardboard and place debris and paper/cardboard in a
glass jar with a metal lid. If a glass jar is not available, use a sealable plastic bag. (NOTE: Since a plastic bag will not prevent
the mercury vapor from escaping, remove the plastic bag(s) from the home after cleanup.)
2.
Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder. Place the used tape in the
glass jar or plastic bag.
3.
Wipe the area clean with damp paper towels or disposable wet wipes. Place the towels in the glass jar or plastic bag.
4.
Vacuuming of hard surfaces during cleanup is not recommended unless broken glass remains after all other cleanup steps
have been taken. [NOTE: It is possible that vacuuming could spread mercury-containing powder or mercury vapor,
although available information on this problem is limited.] If vacuuming is needed to ensure removal of all broken glass,
keep the following tips in mind:
a.
Keep a window or door to the outdoors open.
b.
Vacuum the area where the bulb was broken using the vacuum hose, if available; and
c.
Remove the vacuum bag (or empty and wipe the canister) and seal the bag/vacuum debris, and any materials used to
clean the vacuum, in a plastic bag.
5.
Promptly place all bulb debris and cleanup materials, including vacuum cleaner bags, outdoors in a trash container or
protected area until materials can be disposed of. Avoid leaving any bulb fragments or cleanup materials indoors.
6.
Next, check with your local government about disposal requirements in your area, because some localities require
fluorescent bulbs (broken or unbroken) be taken to a local recycling center. If there is no such requirement in your area,
you can dispose of the materials with your household trash.
7.
Wash your hands with soap and water after disposing of the jars or plastic bags containing bulb debris and cleanup
materials.
8.
Continue to air out the room where the bulb was broken and leave the HVAC system shut off, as practical, for several
hours.
Cleanup Steps for Carpeting or Rugs
1.
Carefully scoop up glass fragments and powder using stiff paper or cardboard and place debris and paper/cardboard in a
glass jar with a metal lid. If a glass jar is not available, use a sealable plastic bag. (NOTE: Since a plastic bag will not prevent
the mercury vapor from escaping, remove the plastic bag(s) from the home after cleanup.)
2.
Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder. Place the used tape in the
glass jar or plastic bag.
3.
Vacuuming of carpeting or rugs during cleanup is not recommended unless broken glass remains after all other cleanup
steps have been taken. [NOTE: It is possible that vacuuming could spread mercury-containing powder or mercury vapor,
although available information on this problem is limited.] If vacuuming is needed to ensure removal of all broken glass,
keep the following tips in mind:
a.
Keep a window or door to the outdoors open
b.
Vacuum the area where the bulb was broken using the vacuum hose, if available, and
c.
