MOUNTING...
1. Remove the existing beacon.

wiring. Positive (+) to the WHITE wire, and Ground (-) to
the BLACK wires protruding from the light assembly. All
connections must use FAA approved techniques.
Note: It is recommended to ground the unit to the buss bar
or the battery. Using the airframe as ground may produce
EMI/RFI interference.
3. Remove the three (3) 6-32 x 3/8” mounting screws from the
light assembly. Do not use longer screws, damage to the
unit may occur.
4. Insert light assembly into mounting location and attach
using screws as mentioned in step 3. There are two sets of
mounting screw locations on the unit for installation
versatility (unit may be sealed around periphery with RTV or
equivalent).
5. If the A440 mounting adapter is used, attach light assembly
to adapter using screws as mentioned in step 3 (unit may be
sealed around periphery with RTV or equivalent).
6. If light assembly is mounted in an inverted position, drill a 1/
8” diameter hole in lens as indicated on the lens label. For
the model SACF series, remove the RTV plug from the hole
in the lens.
7. When installing the light assembly in a rudder mount location,
rudder balance must be checked with reference to the aircraft’s
service manual. The weight and balance should equal the original
rotating beacon.
8. Check all avionics systems for interference from the installation
with reference to AC 43.13-2a, Chapter 4, paragraph 52 (b).
9. Label all switches and breakers, install pilot warning placard.
10. Update aircraft records and complete FAA form #337.

head screw on the clamp ring. Be careful not to lose the #6
hex nut.

INSTALLATION...
The HRCFA & SACF self-contained strobe light assemblies are
interchangeable with Rotating Beacons on any aircraft with a 3.75
inch diameter fairing or mounting adapter. It is not necessary to
change any of the existing wiring, or circuit breakers. The light
assembly must be properly mounted to comply with FAR Part
91.205(c-2) & (c-3). When necessary (such as fuselage
installation), the Whelen model A440 mounting adapter must be
used.
