Externally Mounted Units
If you are installing an externally mounted Marine Radome Air Conditioner, select a location near the
1.
dome to keep the evaporator ducting as short and straight as possible.
NOTE: Ensure that the condenser openings are clear from obstructions.
Mount the unit using the provided hardware, as shown in system manual.
2.
Install evaporator return and supply ducting onto the provided flanges in the base pan. Ensure that
3.
ducting is tight, secure and as straight as possible to minimize bends. Use insulated ducting to reduce
heat gain in the dome.
Install the power cord as described in ELECTRICAL below.
4.
Install the Digital LCD Display Control Panel in an accessible location inside the Radome.
5.
Route the control cable through the provided cord grip in the base pan.
6.
Use a diverter to direct hot-air discharge away from the antenna.

External AC Installation Example
2.3.
Electrical
It is recommended that a separate AC Power cable be ran to the AC Unit, preferably from a different phase of the
electrical system which supplies the ADE & BDE equipment of the Marine SATCOM Terminal. Be EXTREMELY
cautious of length of the run for voltage loss and gauge of the wires for the current that is expected to be drawn.
The Power cable shall comply with the provisions of IEC 60092-350 and -351 in so far as practical. Power cables should
be routed the through separate radome penetrations then that of the signal cable(s) from the junction box to the base
of the ADEs.
The power cable shall be continuous from the closest circuit breaker to the ADE connections within the radome. The
power circuits shall be arranged so that “Active”, “Common” and “Neutral (ground) legs are all made or broken
simultaneously. All circuit legs shall be carried in the same cable jacket.
Turn off the A/C’s power-supply circuit breaker before opening electric box. Each A/C unit requires its
1.
own dedicated circuit breaker. Use the correct size circuit breaker to protect the system.
Remove the electrical box panel to access the circuit board and the terminal block.
2.
While the the terminal block is labeled for proper connections of the electrical supply and ground and
3.
wire, it is always a good idea to refer to your antenna’s installation manual. Make these connections
using solderless terminals.
Double check all wiring connections prior to turning system on
