General Mounting Considerations.6-1 - Furuno 1751 Operator's Manual

6. INSTALLATION
General Mounting Considerations
This radar system is mainly composed of two units: the display unit and the scanner unit.
The scanner unit is designed to withstand the rigors of the marine environment, and if
installed properly is thoroughly waterproof.
The display unit is carefully constructed to be able to withstand the humidity and corrosive
atmosphere common in a pilothouse, but it is not designed to be used outside, exposed to
the environment.
If this radar is to be installed on a small boat, the display unit must be mounted inside an
enclosed cabinet to prevent corrosion. For maximum protection against corrosion by salt
spray, tape the rear connectors and seal them with putty compounds.
The display unit consumes only a moderate amount of power, so there is no need for forced
air ventilation. However, it is necessary to provide adequate Space behind and around the
unit to permit circulation of air and to provide convenient access to the rear connectors.
Even though the picture is quite legible even in bright sunlight, keep the display unit of direct
sunlight or at least shaded because of heat that can build up inside the cabinet.
When the radar is first unpacked, check that all necessary units, parts and materials are
contained, by referring to the equipment lists on pages xi and xii. All Steel and wood works
should be arranged locally.
Installation mainly consists of the following;
1) siting and mounting the display unit and scanner unit
2) running intercoimection cable and power cable
3) establishing the ground
4) connecting optional equipment
5) checking the installation
6) adjustments
NOTICE
Installation of this equipment requires the use of certain power tools as well as electrical and
mechanical skilis, If the purchaser has doubts about his or her abilities in these areas, the
installeUion should be performed by a qualified technician.
