Effectiveness of explosion –proof enclosure must be maintained. Do not dam-
age globe or threads while disassembling or reassembling unit. Lubricated
joints exposed for long periods of time may attract small particles of dirt or
other foreign materials. Body and cover joints should be reassembled im-
mediately.
4.
Loosen the dome clip screw (1−3 turns) and rotate the clip 90°. Remove
the dome to expose the flash tube.
5.
With the dome removed, use a rocking motion and gently remove the
tube. Replace the flash tube with the appropriate replacement part listed in the re-
placement parts list in paragraph IV. F. Replacement Parts.
6.
Place dome in position under hold down tabs (2). Rotate the clip into
place on lip of dome and tighten the screw.
B.
Fuse Replacement for 120 and 240 Vac Units.
To replace the fuse, proceed as follows:
1.
The fuse is positioned on the component side of the P.C. board mounted
in fuse clips. For easy removal, pry one end of the fuse out of the clip with an insulated-
handled screwdriver.
2.
Replace the fuse with one of the same sizes and rating only. The 120 and
240 Vac units use a 1-ampere, 250 volt, slow blow GMC fuse (Federal Signal Part No.
K148A133).
3.
Reassemble the unit by threading globe assembly into the main housing
until tight, then tighten the set screw.
C.
Cleaning the Enclosure.
Maintenance procedures sometime require fixtures to be hosed down for good
housekeeping. The circuit must be turned OFF and fixture globe MUST be
allowed to cool to ambient room temperature before cleaning.
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.
D.
Lubrication.
Threaded joint on cover should be kept well lubricated with a corrosion-in-
hibiting grease such as petrolatum or soap-thickened mineral oils. If corrosive prod-
ucts have accumulated on explosion-proof joints and cannot readily be removed with
solvents, the parts should be discarded and replaced.
Never use an abrasive material or file to remove corrosive products 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.
