GRS AW, GRSH AHW, LGFV Mounting Frame Installation Instructions
NEW INSTALLATION
Non-accessible ceiling:
(Plaster, drywall, etc.)
1. Release clamping latch arms and ad-
just channel bars to the correct
spacing between joists as shown in
Figure 1.
2. Mounting Channel Bars
Flexible Wiring Method
Bend ends of channel bars 90° and
mount to joists with vertical
adjustment at its lowest point on the
mounting frame. Make sure bottom
of the flange is flush with the bottom
of the joists. Secure mounting
frame into position by closing the
clamping latch arms. Channel bars
will accommodate up to
24” O.C.
joists.
Non-Flexible Wiring Method
If non-flexible wiring methods are
used, follow procedure for Flexible
Wiring Method, then lower mounting
frame equal to the thickness of the
finished ceiling, or slightly above as
shown in Figure 3.
3. Remove knockouts on junction box
to feed power supply to fixture as
shown in Figure 4. Supply wire must
meet applicable electrical codes
and be rated for a minimum of 90°C.
Junction box is thru-wire rated for
8-No. 12 AWG conductors (4 in - 4
out).
4. Complete necessary wire connect-
tions. Snap the door onto the
junction box. For fluorescent
applications: if the ballast is
desired on the opposite side of the
junction box, pass the entire door
and ballast assembly through the
junction box and snap into place.
5. For HID applications: pivot ballast
tray onto spacer brackets as shown in
Figure 5. Thermal protector assembly
must be plugged into the appropriate
power supply voltage (120V, 277V or
347V). Snap door onto the junction box.
6. If yoke assembly is provided, slide feet
of yoke under lanced up tabs on the
mounting frame as shown in Figure 6.
This is a friction fit and may require
some force to engage properly. If
desired, yoke assembly can be se-
cured to the mounting frame by a rivet
or screw (not supplied).
TROUBLE SHOOTING CHART
Check for any visible damage to the lamp or frame-in module. lf they seem in good condition, locate the problem in the following list of
possible causes and corrective actions.
Symptom Possible Cause Corrective Action
LAMP FAlLS
TO LlGHT ·Circuit feeding the fixture not energized
·Wiring error in circuit or module connection
·Faulty lamp
·Line or ballast output
·Faulty ballast
·Ambient temperature too low
·Check circuit breaker or fuse to ensure that circuit is energized.
·Examine fixture splice box to ensure that connections are correct.
·Remove the faulty lamp and substitute another lamp, preferably one
that is known to light. lf the lamp lights, replace the original with a
new one.
·Check line voltage at fixture. Check open circuit voltage.
·Check circuit continuity.
·Check ballast rating against existing environmental conditions.
LAMP GOES OUT
AFTER LlGHTlNG
·Faulty lamp ·Occasionally a lamp will exhibit this symptom rather than
simply failing to light. Substitute a new lamp.
LAMP CYCLES
ON AND OFF
·lnsulation is too close to fixture
·Lamp wattage too high
·Ballast output voltage low
·Remove insulation from around module (at least 3")
·lnstall lamp wattage specified in housing.
·Check line voltage at the fixture. Check open circuit voltage.
