Furuno 1830 - Installation; General Mounting Considerations; Detailed Instructions

INSTALLATION
As was pointed out in the Introduction to this manual, this machine can do
its intended functions only if it is inatalled properly.
GENERAL MOUNTING CONSIDERATIONS
Thia radar consista of two units, the Display Unit and the Scanner Unit.
The Scanner Unit has been designed to withstand all the rigors of the
marine environmenl, and if installed properly, is thoroughly waterproof. A
"domed" type of Scanner Unit. where the scanner meohanism is anclosed in a
thermoplastic resin dorne, ensures that halyards and other rigging won’ t get
tangled up in the rotating scanner.
The Display Unit is carefully conslrueted to be able to withstand the
humidity and corrosive atmosphere common in a pilothouse, but it is not
designed to be used outside, directiy exposod to the environment!
Many owners will undoubtedly use this radar on small boats. The Display
Unit must be mounted inside an enclosed cabinet. Corrosion can occur,
especially on the rear connectors exposed to salt spray, unless these are
taped and thoroughly sealed with putty compounds made especially for this
purpose. Most small boats are equipped with such an enclosed cabinet, and
most have clear doors so thal equipment may be seen behind them.
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 Display Unit to allow some circulation nf cnoling
air and to provide convenient access to the rear connectors.
Even though the picture is quite legible even in bright sunlight, it is a
good idea to keep the Display Unit out oT dlrect sunlight or al least shaded
because of heat that can build up inside the cabinet.
It is a regrettable faet of modem life that small attrantivc electronio gear
seems to atlract undue attention from thieves. In your installation planning
it is a good idea to provide means either to hide the gear when you are not
aboard or take the gear off the boat completely when you are finished for
the day. Consideratlon should be made to provide Space for access to the
mounting hardware on the side and to the connectors behind the Display
Unit.
DETAILED INSTROCTIONS
SUANNEK UNIT INSTALLATIUN
The Scanner Unit is completely watertight when installed correetly. It
ahould be plaoed where thero is a good all-round view with, as far as
possible, no part of the ship's superstructure or rigging intercepting the
scanning beam. Any obstructions will cause shadow and bhnd seetors. A
mast, for instance, with a diameter considerably less than the width of the
scanner, will cause only a small blind sector, but a horizontal spreader or
crosstrees in the same horizontal plane as the Scanner Unit would be a mueh
more serious obstruction and the Scanner Unit would need to be placed well
below or ubu ve it.
