Furuno FAR-2228 Installation Manual page 29

• For X-band radar, if it is
necessary to lay down the
radiator before you fasten
it to the Antenna Unit, lay
it down with the wave-
guide up, to prevent dam-
age to the cylinder that
surrounds the waveguide.
• If the de-icer is installed, a two-pole breaker (supplied locally) must also be installed.
Note: For more information, please refer to IMO SN/Circ.271 "Guidelines for the in-
stallation of shipborne radar equipment.
1.1.2 How to assemble the Antenna Unit (FAR-2x18/2x28/2x38)
The Antenna Unit consists of the antenna radiator and the Antenna Unit chassis, and
they are packed separately. Fasten the antenna radiator to the Antenna Unit chassis
as follows:
1. Coat the hatched area shown in the figure in step 2 with the supplied adhesive.
2. Remove the protective waveguide cap from the waveguide on the radiator brack-
et.
Do not apply the adhesive to
these locations.
3. Pass the Gasket (03-182-3186, supplied) to six sets of the Antenna fixing bolts
(03-182-4188, supplied, w/two flat washers), and then coat the threads of the An-
tenna fixing bolts with the supplied adhesive. Set the radiator on the radiator
bracket.
