3.
Using a No. 2 Philips screwdriver, remove two 8-32 oval head screws holding
the printed circuit board assembly to the die-cast housing. Be sure to retain
the two nylon screw bushings isolating the bracket from the screws.
4.
Gently lift the printed circuit board assembly from the housing and turn the
assembly over to access the component side of the printed circuit board.
5.
Locate jumper J3 and lift the jumper to remove it from "Flash" setting. Re-
seat the jumper over the pins labeled "Steady." See Figure 2 on page 9.
6.
Place the printed circuit board assembly back into housing, making sure that
four insulating pads are seated between the metal bracket and die-cast hous-
ing. The bracket must be oriented so that the notch in the bracket is aligned
with the ground screw in the die-cast housing. This step must be carefully
followed to prevent arcing and dielectric failure.
7.
Slide two 8-32 oval head screws into their screw bushings and tighten screws
to secure the printed circuit board assembly to the die-cast housing.
8.
Thread the dome assembly back onto the housing by turning it clock-wise to

Cleaning the Enclosure
Maintenance procedures sometimes require fixtures to be hosed down for good
housekeeping. The circuit should be turned off prior to hosing down.
The fixture should be cleaned periodically to maintain maximum light output.
Only mild, non-abrasive cleaning agents should be used. The glass globe should be
regularly inspected for scratches and chips, and if damaged, MUST be replaced.
C.
Lubrication
Threaded joint on cover should be kept well lubricated with a corrosion
inhibiting grease such a petrolatum or soap-thickened mineral oil. If corrosive materi-
als have accumulated on the threaded joints and cannot be removed with solvents, the
parts should be discarded and replaced.
Never use an abrasive material or file to remove corrosive materials from
threaded surfaces. In extremely corrosive locations, equipment should be
periodically inspected to guard against unusual deterioration and possible
porosity, since this may weaken the enclosure structurally.
D.
Service

with any problems that cannot be handled locally by a Federal Signal Distributor or
