SECTION II -
INSTALLATION
2.1
GENERAL INFORMATION
2.1.1
Scope
This section of the manual will provide the needed information to successfully complete the installation of your new
COM 2KR –
Remote VHF Transceiver
. Please read this section completely before proceeding with the installation
process. Although the COM 2KR installation procedures are designed with the do-it-yourselfer in mind, we at Val
Avionics Ltd. strongly suggest that you seek the advice of a qualified avionics installation facility before beginning
this or any other installation project. Qualified avionics installation technicians can offer good advice as to time-
tested installation practices and techniques that can save you many hours of time and frustration.
2.2
UNPACKING AND INSPECTION
Use care when unpacking the equipment. Inspect the unit and supplied parts for visual signs of damage during
shipment. Examine the unit for loose screws, dents, broken buttons and other signs of damage that may have
occurred during shipment. Verify the contents of the container with the list in section 1.5. If any damaged or missing
parts are discovered during the inspection save the shipping material and contact the freight carrier to file a claim. If
it is suspected that parts were omitted from the container please feel free to contact Val Avionics Ltd., to acquire the
missing items.

EQUIPMENT INSTALLATION PROCEDURES
2.3.1
Cooling
Requirements
Forced air-cooling is not required for the COM 2K –
VHF Transceiver
. However, when planning the location for
mounting, ensure adequate spacing from heat producing sources such as heating or defrosting ducts.
2.3.2
Mounting Requirements
The COM 2KR should be rigidly mounted in the aircraft cabin using the hardware provided in the installation kit.
Ensure that the mounting location will provide easy access for future maintenance. Ensure that the mounting
position will provide adequate clearance between the unit and the associated wire harness and the aircraft controls.
Consult FAA Advisory Circular AC 43.13-2B for acceptable practices and techniques.
2.3.3
Wire Harness Fabrication
Val Avionics Ltd. Strongly recommends the use of a factory fabricated wire harness (VPN 751028) with your new
COM 2KR –
Remote VHF Transceiver
. Use of the factory fabricated wire harness will ensure proper operation of
the COM 2KR, reduction in the occurrence of interfering signals and ground loops, greatly reduced installation time,
and provide prolonged trouble-free performance of your new equipment.
Although strongly recommended, it is not required to use the factory fabricated wire harness when installing the
COM 2KR. A wiring harness can be fabricated in the field. Refer to appendix B of this manual for a complete
wiring diagram. The COM 2KR is connected to the aircrafts avionics bus via a 5 AMP circuit breaker. All wires
must be 22 AWG MIL-SPEC, unless otherwise noted in accordance with current regulations. Two and three
