LUMINAIRE MAINTENANCE
GENERAL
READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
SAVE THESE INSTRUCTIONS.
IMPORTANT SAFEGUARDS.
When using electrical equipment, basic safety precautions should always be followed including the following:
1. READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
2. Do not let power supply cords touch hot surfaces.
3. Do not mount near gas or electric heaters.
4. Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.
5. The use of accessory equipment not recommended by the manufacturer, may cause an unsafe condition.
6. Do not use this equipment for other than intended use.
Lamps
Fluorescent lamps typically have an average rated life of 20,000 hours (meaning some lamps will fail sooner, some later). Lamps
are driven in various combinations depending on ballast type, layout, etc. Under normal operating conditions it is recommended
that a comprehensive maintenance plan be developed to achieve a complete lamp change out every 48 to 52 months. Some lamp
failure will occur before this recommended interval and single lamp replacement should be considered where necessary.
Any required maintenance should be possible by one person depending on accessibility of fixtures. Lamps are removed by turning
1/4 turn (works for both bi-pin and butt-on sockets). Use care when removing or installing lamps and do not work above others.
Ballasts
Ballasts are generally very reliable and have a projected life of twenty years under normal operating conditions. If a situation arises
where two adjacent lamps are out, there could be a ballast problem and a replacement may be required. Lamp replacement
should be tried first in this instance and failing that, the appropriate ballast replaced.
Before attempting to verify and replace a ballast it will be necessary to take the affected fixture module off line. To isolate power
from the unit, all circuits should be disconnected. Ballasts locations can be found per the fixture's cross section view found in the
project drawing set. Ballasts are normally found below a reflector or pan and are secured to either the extrusion housing or the
ballast pan itself. Reflectors and pans are retained by sheet metal or machine screws. Once the retaining screws are removed,
the reflector or pan is completely detached from the fixture exposing ballasts and wiring.
During the replacement process, special care should be taken to replace all fasteners and reconnect all applicable plugs.
Note that ballasts are warrantied by the ballast manufacturer and not by Ledalite. Ballast information is found on the ballast label.
Contact Ledalite for the ballast breakdown by project if required and for service line telephone numbers of ballast manufacturers.
Internal Components
Luminaires are certified by ETL to UL and CSA standards. When luminaires are operated as designed, all internal components will
be relatively inert to the effects of surface oxide accumulation which is the primary cause of scale and corrosion. The conditions of
certification preclude the operation of luminaires with missing, open or improperly installed lenses or covers.
Special Tools
Readily available tools such as bladed screwdrivers are required for maintenance and repair of system components. In some
cases, screws have a combination head for a bladed or no. 2 robertson square drive bits. Aircraft cable cutting: recommended
cutters, H.K. Porter cable cutter cat. No. 0690TN, or Klein all purpose shears cat. No. 1104.
Outside Painted Surfaces
The outside surfaces of all components are finished with high quality powder paint. This finish is specially formulated to provide a
durable scratch resistant coating. It is recommended that all component surfaces be cleaned on a regular schedule to remove
accumulated dust and dirt. Care should be taken to use only non-abrasive substances i.e. clean cloths and house hold solutions
such as a non-streaking bathroom tub and tile cleaner. Best results are obtained by wetting a cotton cloth and wiping clean. Do
not spray solutions directly onto the fixture, residue can accumulate on optics which can be difficult to remove.
Internal Reflector Systems
Lighting performance is affected significantly by the reflectivity of the optical system and it is recommended that all fixture reflectors
be dusted periodically, possibly during a systematic lamp changing operation. Any cleaning of reflectors should be carried out with
care as the materials used to optimize performance are at the same time vulnerable to marring. It is recommended that a hand
held vacuum cleaner with a soft brush head be used for this operation. Grease can be removed using common household glass
cleaner, and a soft cloth.
Plastic Surfaces
Plastic materials, which form part of the exterior of the fixtures, such as lenses, are more susceptible to scratching and marring
than the painted finish. Special attention should be paid to the cleanliness of the materials, use mild soap and water only.
READ AND FOLLOW ALL SAFETY INSTRUCTIONS.
