2.2 UNPACKING AND INSPECTING EQUIPMENT
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for
evidence of damage incurred during shipment. If a claim for damage is to be made, save the ship-
ping container to substantiate the claim. The claim should be promptly filed with the transportation

2.3 EQUIPMENT INSTALLATION
KN 63 INSTALLATION
A. The KN 63 may be mounted rigid, either horizontally or vertically.
B. Avoid mounting the KN 63 close to any high external heat source. Allow one inch
of free air space around top and sides of unit.
C. Allow adequate space for installation of cables and connectors.
D. The KN 63 must be mounted a minimum of three feet (3') from the DME antenna.
E. In order to function properly, the KN 63 must be well grounded to the aircraft frame.
Using fine sandpaper, remove all paint and protective coatings from the areas on
the equipment shelf that will contact the unit or its mounting rack. Apply Alumiprep
No. 33 (016-01127-0000) following the directions on the container to cleanse the
metal of any residue. Then apply Alodine No. 1001 (016-01128-0000) to these ar-
eas following the directions on the container. The equipment shelf must also be
well grounded to the aircraft frame.
F. For horizontal mounting, secure the unit in place with four 8-32 pan head phillips
screws (089-05909-0007), four 8-32 hex nuts (089-02015-0037), and four #8 lock
washers (089-08111-0034). The screws should be inserted through two holes in
the front plate tab and through two slots in the rear plate tab. The mounting rack
is not used for horizontal mounting.
G. For vertical mounting, the mounting rack is used. First attach the hold down
clamp (075-00021-0001), hold down screw (089-05529-0032), compression spring
(078-00054-0000), and #8 lock washer (089-08111-0034) to one of the hold down
