JAA CAUTION
All
wiring
must
be
performed
by
a
licensed
electrician.
Because
of
varying
city
electrical
codes,
the
dealer
should ensure
that
instal-
lation
will
meet
local
requirements.
Pelton
&
Crane
cannot
be
responsible
for
an
installa-
tion
which
does
not
meet
local
electrical
codes.
The

available
in
a
variety
of
models.
Identify
the
particular
model
for
your
installation
application
and
install
the
following
instruction
for
the
specific
unit
as
outlined.
NOTE:
For

Han ration
1. The LFIl includes a universal arm adapter
which may be right or left-hand positioned.
All lights shipped from the factory are posi-
tioned for right-handed operation. Should
the doctor need a left-handed light, remove
the screw A adjacent to the rear arm/arm
adapter joint B. Rotate arm adapter until
other arm adapter hole aligns with rear arm
hole. Reinsert and tighten screw.
Optional Wall Mounting Bracket For Unit Light
2. An optional wall mounting bracket (006719)
or wall mounting bracket and plate assembly
(011203) are available (when required) to
mount unit light to wall.
NOTE: Wall mounting bracket (006719) is
not recommended for dry wall installa-
tion. Order 011203 for dry wall installa-
tion.

install wall mounting bracket (006719) as follows
1. Position bottom edge of bracket A 54”
(137.2 cm) from floor. (Height may vary for
individual requirements.)
Position wall mounting bracket with bottom
center located within 30” (76.2 cm) of an
electrical outlet (1.6 amp, 120 VAC, 60 Hz).
As an alternative, the wall mounting bracket
has a recess for mounting directly over a
duplex outlet if located 54” (137.2 cm)
above the finished floor surface.
2. Secure wall mounting bracket to wall with
screws entering solid wood at least 2”
(5.1 cm). Framing behind wall must be
secure.
Route power supply cord from light through
wall mounting bracket hole and plug into
electrical outlet.
Apply light application of petrolatum or oil to
outer surface of bushing before inserting
into the wall mounting bracket. Insert rear
arm bushing in wall mounting bracket.
Ensure wall mounting bracket is plumb to
| prevent light from drifting.

wall receptacle) with three #24 x 2-1/2”
long minimum wood screws.
4. Fasten wall mounting bracket to plate with
four
1/4”—20 screws.
Apply light application of petrolatum or oil to

20. Route wiring from trolley through column.
21. Screw end of column securely in the trolley.
22. Insert and tighten two trolley set screws.
23. Place a piece of electrical tape around a
1/8" drill bit to mark depth to which pilot hole
is to be drilled.
24. Atter locating the 3/32” pilot hole in the trol-
ley, drill a 1/8” hole through trolley/column
assembly to a depth of 5/8”. Drive in roll pin
flush with outside of trolley.
A WARNIN
Failure to mark drill bit, or failure to control
depth of drill bit may result in electrical wir-
ing damage and subsequent electrical
shock.
AWARNING
Set screws must be tightened securely and
roll pin installed to prevent column from
unscrewing during operation. Failure to
install roll pin and tighten set screws
securely could result in light falling from
ceiling.
NOTE: Ensure column is vertical to pre-
vent trolley from drifting. Adjust pallet
with shims if necessary.

25. Connect electronic phase control to wiring in
column with 2-pin Mate-n-Lok® connector.
À CAUTION
To prevent wires from twisting, do not rotate
electronic phase control with column.
26. Gently slide the electronic phase control into
one column with column weld seam A cen-
tered

INSTALLATION
NOTE: If desired, tripod cover and col-

installed before finished ceiling is in
place. For new construction, a mounting
plate assembly (007257) may be ordered
to facilitate installation.
Recommended ceiling positions for various
methods of LFCII operation are shown.
Location may be varied. Obtain approval
from doctor before locating framing and
electrical outlet.
NOTE: The maximum height the LFCII
may be mounted is 13’ (396.2 cm). How-
ever, Pelton & Crane does not recom-
mend any mounting in excess of 10’
(304.8 cm).
Framing
Provide adequate framing to support
approximately 200 pounds dead load.
Locate framing so ceiling joists A and block-
ing between joists are positioned so that
mounting bolts through legs of tripod can be
screwed directly into framing.
Wiring
Stub out 3/8” flexible armored conduit
from electrical box in ceiling to location as
shown. A 1.6 amp, 120 VAC, 60 Hz electri-
cal supply line is required for the LFCII, or a
3.2 amp, 120 VAC, 60 Hz line for the LFCII-
D.
Protect circuit with a 15 amp fuse or circuit
breaker. (Also refer to LFCII and LFCII-D
installation Template, 096021).

supply and transformer. Wall
switch can be switched off dur-
ing electrical storms to prevent
transformer damage caused by
voltage overloads.

5. Drill three 3/16” pilot holes B
to mount lag bolts.
6. Drill three 3/4” holes C
through sheet-rock, acoustical
tile or plaster.
NOTE: For electrical supply
connections, use wiring suit-
able for at least 90°C (194°
F)
7. Secure tripod D and ceiling
plate E to framing with 1/4“ x
4” lag bolts F and washers
G. The 3/4“ diameter spacers
H should be in direct contact
with the framing. Insert ceiling
plate between the 3/4”

NOTE: If spacers rest against
soft sheetrock, acoustical
tile or plaster, the light may
be unstable.

1/8" drill bit to mark depth to which pilot hole
is to be drilled.
11. After locating the 3/32” pilot hole in the tri-
pod, drill a 1/8” hole through tripod/column
assembly.
Failure to mark drill bit, or failure to control
depth of drill bit may result in electrical wir-
ing damage and subsequent electrical
shock.
12. Drive in roll pin D flush with outside edge of
tripod.
Set screws must be tightened securely and
roll pin installed to prevent column from
unscrewing during operation. Failure to
install roll pin and tighten set screws
securely could result in light falling from
ceiling.
13. Ensure column is plumb. Adjust leveling
nuts E on tripod until column is plumb.
Loosen lag bolts F slightly before making
