INSTALLATION
A.
TRUNION ORIENTATION
The DSF can be utilized in one of three different trunion orientations.
The luminaire ships from the factory in the ‘Trunion Down’
orientation. To achieve another trunion orientation, remove the
aiming bolts (M6) and loosen the main trunion bolts on the side of
the fixture housing (M8). Rotate the trunion to the desired
orientation and reinstall the trunion aiming bolts in the threaded
holes of the fixture housing that be align for the desired application.
The aiming bolts are designed to be installed 180 degrees from each
other.
a.
TRUNION DOWN ORIENTATION
The DSF is typically mounted with the trunion below the
luminaire. This mounting orientation is typical of the
HID luminaires the DSF is designed to replace.
b.
TRUNION UP ORIENTATION
The DSF can be mounted with the trunion above the
luminaire with the fixture body below the mounting
location. This orientation is useful when utilizing the
DSF640 on a CHM lowering device system or when
replacing certain existing HID installations.
C.
TRUNION OUT ORIENTATION
The DSF can be mounted to a vertical surface such as a
building wall with the trunion horizontal to the ground.
This orientation makes mounting to vertical surfaces
easier.
MOUNTING
The DSF640 flood light is provided with a heavy duty mounting
trunion. The mounting trunion has clearance for a ¾” main
attachment bolt. Raise the luminaire into position and attach the
main ¾” trunion bolt. Snug tight the main bolt to hold the luminaire
in place. The luminaire shall be adjusted to the proper left-right
aiming angle by rotating the luminaire on the main trunion bolt.
Once the proper left-right aiming angle has been achieved, tighten
the main trunion bolt to 80-90 ft*lb of torque. NOTE: Refer to
aiming instructions for additional details on proper aiming
procedure.

347V AND 480V SYSTEMS
For fixtures optioned with the T3 or T4 option, a 750VA
Toroidal transformer will be factory integrated into the
luminaire to step down incoming power to 277V. The
enclosure will include a dedicated weatherproof cord
grip for incoming power and outgoing power to the
luminaire. The wiring from the transformer to the
luminaire will be factory assembled and shall not be
modified in the field. The incoming power wires will
include a field ready butt splice joint. Route the
incoming power via a 16/3” SO cable through the cord
grip and connect incoming power to the supplied butt
splice joints. Once wiring is complete, ensure the cable
grip is properly tightened on the incoming power cable.
WARNING: In a L-N-G system, ensure the system
neutral is connected to the incoming white wire only. G
is exclusively reserved for electrical ground and B is
always hot (Line).
18/2 POWER CABLE FOR 010VDC CONTROL IF
NEEDED.
In the pre-aimed configuration, both the horizontal and vertical aiming
indicators with be marked with the appropriate aiming settings. Adjust the
luminaire until the aiming mark aligns with the aiming bolt. IF the fixture is
not pre-aimed from the factory, follow the aiming steps below. NOTE: The
vertical aiming bolts are Allen head socket bolts. The hardware is METRIC
sizing. Use of incorrectly sized hardware to tighten these bolts could
damage the fasteners.
To properly aim the DSF640, the mounting structure shall have mounting
holes in accordance with the CHM mounting detail. Contact CHM
Industries for the drill pattern necessary to support the DSF640. If
purchasing mounting structure from CHM, the plates will be factory drilled
to accommodate the DSF.

AIMING PREPARATION
Prior to aiming of the flood lighting fixtures, it is critical to ensure the
proper distributions are located in the appropriate location on the support
structure. The label on the underside will show the complete part number
including the light distribution. Distributions are in degrees and include
15D, 20D, 30D, 45D and 60D beam angles. Distributions should be matched
to the supplied aiming array illustrating the fixture array, aiming angles and
specific distribution.
The pole and crossarms must be braced so that they are both
LEVEL (parallel) with the ground.
Each floodlight is attached to the crossarm(s) so that the glass
lens is LEVEL (parallel) with the ground.
Loosen the (4) aiming bolts (2 per side) and (2) main trunion
bolts. The aiming bolts are M6 and the main trunion bolt is
M8. An inclinometer is positioned on the glass lens
perpendicular to the crossarm. The down angle adjustment
that is indicated in the square boxes of the fixture
arrangement and aiming schedule is made. The bolts that
attach the trunnion to floodlight housing are tightened. Match
mark the location of the aiming bolt (Sharpie permanent
marker will work here) and the trunion aiming angle so that
the fixture can be repositioned to the correct location.
The vertical aiming bolts and main trunion bolt are then
loosened and the floodlight is rotated back to its original
horizontal (level) position in preparation for Left or Right
adjustment. Retighten the bolts.
The inclinometer is positioned on the glass lens parallel to the
crossarm. The crossarm attachment bolts are loosened, the
Left or Right angle adjustment is made, and the bolt is
retightened.
Finally, the trunnion/fixture bolts are loosened and the
floodlight is rotated to its final vertical position (against the
reposition stop). Make sure that the stop is not bent by rapid
movement during rotation. Securely tighten all bolts and
screws.

The glass on the optical assembly is high strength tempered
glass. It can be cleaned with a standard cleaning solution like
Windex. It is strongly recommended that a microfiber cloth is
used to clean the glass to avoid scratches in the surface.
The perforated body of the DSF is designed to allow the airflow
necessary to cool the LED array to extremely low and stable
operating conditions. In certain extreme environments like
arena applications where dirt is utilized (rodeo, motorcross,
monster truck, etc), extreme levels of dirt can build up on
luminaires. In these applications, it is suggested that the DSF is
inspected for dirt build up on the cooling apparatus. Should
there exist an excessive level of dirt built up, it is suggested
that the luminaire be blown out with compressed air. This is
not unique to the DSF and is also suggested for standard HID
and competitive LED products.
The DSF is covered by a 5 year complete replacement warranty
(longer terms available) and will not require any internal
maintenance over that term.
Once the fixture is installed on the mounting structure, remove
the external visor from the shipping package.
Slide the visor ring around the LED housing until the visor
bracket is making contact with the gray fixture housing body.
