INSTALLATION AND MAINTENANCE DATA SHEET
The fixture unit MUST BE installed with one of the following
mounting hoods for safe operation.Failure to use fixture
unit with one of the following mounting hoods voids warranty as well as the U.L. Listing and creates the risk of fire
or explosion.
DIRECTIONS FOR FIXTURE
INSTALLATION
Use the installation drawing as a guide. Install mounting
hood first as all wiring connections are made in the mounting
hood. The fixture unit requires no internal wiring
connections.
1. Remove the connection bloc k (VPT-7) from the mounting
hood by loosening (but not removing) the two Phillips
head screws.T urn connection bloc k counter-cloc kwise to
remove.
2. When using ceiling (AAC- ) or short bracket (AASB-),
mounting hoods, threaded adapter (59064050000) can
be removed by lifting gasket (59064034000) to access
set screw.
• Loosen set screw and turn adapter counter-clockwise for
easier access to junction box.
3. Install mounting hood to conduit system (and/or
wall or ceiling). If usi ng pendant, secure the hood to
the conduit system with the set screw.
4. Pull supply wires from the conduit into the junction box.
• Use supply wire rated 110° C minimum.
5. Secure threaded adapter (where applicable) to junction
box and tighten all set screws. Make connection of supply wires to the VPT-7 connection block by attaching
“hot“ voltage lead to the brass terminal and common
"neutral" lead to silver terminal.
6. Secure VPT-7 connection block to threaded adapter or
mounting hood by slipping over Phillips head screws;
turning clockwise and tightening screws.
7. Install lamp into fixture unit. See directions under "Lamp
Installation Instructions."
8. Inspect threads of mounting hoods and of the fixture
unit to be sure they are clean and free of damage.
Inspect globe for any chips, scratches or cracks.
CAUTION
9. Thread the fixture unit into mating threads of mounting
hood until tight against gasket of mounting hood.Locking
spring of fixture unit should engage with notches on
mounting hood.
10. Install guard and/or reflector if desired. Check tightness
of set screws and all threaded joints.Activate supply circuit to test fixture.

MAINTENANCE DATA
• To relamp, see "Lamp Installation Instructions."
• To maintain maximum light output from this fixture,
it should be cleaned periodically as follows:
1. The aluminum exterior of this fixture should be
cleaned only with a mild soap or cleaner, and
should be rinsed with water immediately.
Alkaline or acidic cleaners will attack the protective
coating of epoxy on the fixture and should not be
used.
This will allow the epoxy to protect the fixture from
corrosive elements in the atmosphere and result in
longer fixture life.
2. The glass globe should be cleaned using a soft
cloth and a non-abrasive cleaner. The globe
should be regularly inspected for scratches or
chips. If the globe is scratched or chipped, it must
be replaced.
3. The porcelain enamel reflector may be cleaned
with any non-abrasive detergent or glass cleaner.
• These periodic cleaning procedures are important
to prevent the accumulation of dust and dirt which
will impair the light output of the fixture.
• When relamping, be careful not to damage the
external threaded areas, since they maintain the
fixture’s explosion-proof properties.
• When removing and repairing fixture lubricate
threads only with Appleton TLC-3 conductiv e, high
temperature lubricant. This should only be necessary if threads are no longer coated with the blue
or black color of the TLC-3 dry film teflon lubricant.
• See Page 3 , Figure 5 for replacement par ts list.
OPERATIONAL DATA
• The fixture must be operated in an environment
that does not exceed 40°C.
• The fixture may be operated on AC power only up
to 300 volts.Use lamp rated for operating voltage.
• Use supply wire rated 110°C minimum.
WARNING
•To reduce the risk of fire or explosion, do not
install where the operating temperature exceeds
ignition temperature of hazardous atmospheres.
•Refer to the nameplate on the fixture for
maximum operating temperature and for
proper fixture classification.

release lugs for leverage.
• Once loosened from mounting hood, fixture unit can
be quickly unscrewed by hand. Do not remove fixture
unit from mounting hood under load.
3. Place fixture unit on bench with globe side up.
4. Remove globe ring using pry notches if necessar y,
turning counter clockwise
5. Refer to fixture nameplate for proper lamp wattage and
type.
• Inspect globe for chips or scratches.

INSTRUCTIONS
1. Remove fixture unit from mounting hood and
remove globe assembly per directions under
"Lamp Installation Instructions".
2. With socket side up, locate connection block set
screw. (8-32x15/16” slotted headless screw)
below socket, neat pyrex cylinder wall. Loosen set
screw.
3. Place fixture unit with socket side down on soft
clean level work surface.
• Threaded opening of fixture unit with contact ring
and center pin should be exposed.
• Fixture nameplate should be right side up.
4. Locate pry nipples on top of exposed socket
contact block assembly. Use preferably
adjustable pliers against opposing dimples and
loose block assembly counter-clockwise.
• Once loose, block should be easily removed by
hand turning counter-clockwise.
5. Install new socket assembly by threading clockwise into top of fixture unit. Continue until hand
tight against mating surface.
• Check by turning fixture unit upside down to see
that no gap remains between cast interior and
block.
• Do not over-torque the socket assembly into
place, a hand tightened socket assembly is sufficient
to maintain integrity of fixture.
• DO NOT use socket to turn or remove
assembly. See inser t at right.
6. Tighten connection block set screw.
7. Reassemble fixture per directions under "Lamp
