Installing Enclosed & Gasket Series 705 type Units

This fixture is UL listed for Damp and Wet location only.
I. CAUTION: Risk of fire or electrical shock. Disconnect all power before installing or maintaining unit. This fixture should only be installed by a qualified (Licensed) professional.

II. The outer housing and gasket of this product are resistant to many hostile environments and chemicals. Every environment is different. There is no guarantee the fixture will be sufficiently resistant in any given application. Consult factory for information regarding the products application in a specific environment or exposure to specific chemicals.

III. Make sure application and installation area are classified correctly.
    A. This fixture is UL listed for Damp and Wet location only. It is not UL classified or listed for class I, II, or III areas.
    B. UL listed Damp and Wet location fixtures are not designed to be gas tight and they will ‘breath’
      1. Units are shipped without any holes in the outer housing to insure they are sealed when they leave the factory.
      2. Air , and the moisture contained in that air, will enter or leave through conduits, fittings, threads, or any other opening, as pressure differences inside and outside the fixture enclosure occur. If warm moist air intrudes into the fixture and then cools, moisture may condense against interior surfaces of the fixture and corrosion may result.
    C. Installation in areas with a high ambient temperature (showers, steam rooms, etc.) may cause the plastic, lens, and /or gasket to soften. This may damage the fixtures ability to maintain a proper seal. High ambient temperatures may also cause ballast and or lamp overheating resulting in reduced ballast and lamp life and may also cause the ballast to leak or go into thermal overload resulting in thermal cycling.

    A. Verify correct Mechanical fit and function
      1. Plastic
      2. Housing
      3. Gasket and seal
      4. Latches
      5. Mounting Brackets
      6. Missing or broken parts

X. Use a insulating bushing at holes (‘KO’s) where wires enter or leave metal housing to prevent chaffing on burs.

XI. Use close nipples when running fixtures in continuous runs.

XII. If surfaced mounted, seal all fasteners that penetrate the housing, inside and out, using RTV compound.

XIII. If Unit Is To Be Pendant Hung:
    A. Use a minimum of two 1/8” IP, ˝” trade size, 3/8” dia. OD, stems for support.
    B. Backup all locknuts and other fastners with large washers for proper support.
    C. Securely hang pendants on correct centers (consult factory to verify current backplan. Request a physical sample before proceeding.
    D. Supply wires must be run through metal stem directly into housing so they are protected at all times.

    A. When properly installed, these brackets are certified to comply with the standards required for earthquake safety of the Department of Building and Safety of the City of Los Angeles. They are flexible to absorb shock and vibration.
    B. Be sure the mounting bolts are properly secured to the mounting surface.
    C. Be sure the brackets are completely snapped onto the housing edges and are secure.
XV. Seal All Stems, Conduits, and Fittings, Both Outside And Inside, At Entrance To Fixture.
