- INSTALLATION AND SERVICE REPORTS
Fit ting the Upmast Trans ceiver to the Ship
27 To install the upmast transceiver, proceed as follows:
(1) Mark out and drill four 17 mm gearbox mounting holes at the mounting position.
WARN ING
THE UNIT MUST NOT BE LIFTED BY MEANS OF THE SWING CAST ING.
THE LIFT ING SUP PORTS MUST GO UN DER THE CAST ING.
IF IT IS NECESSARY TO FIT THE ANTENNA BEFORE INSTALLING THE
TURNING MECHANISM, THE TURNING MECHANISM MUST NOT BE
LIFTED BY THE ANTENNA. THE TURNING MECHANISM MUST BE
HOISTED TO THE FIXING POSITION USING A SECURED BLOCK AND
TACKLE, OR BY ROPE STROPS.
(2) Using the lifting gear, install the upmast transceiver/turning mechanism at the
mounting position, ensuring correct orientation.
(3) Use the shim washers supplied to take up any distortion in the mounting platform.
Failure to do so may cause the casting to crack when bolts are tightened to the
correct torque.
(4) Secure the upmast turning mechanism using the noise reduction kit supplied in
the Fitting Kit GTX-A144 (refer to Figure 3) and secure the fittings to a torque of
20 Nm, as specified on Figure 3.
Fit ting the Low Pro file Antenna
28 It is recommended that lifting slings are used in an arrangement similar to those shown in
Figure 4 to position the low profile antenna on the transceiver/turning mechanism.
CAUTION
When unpacking the Antenna, ensure that the Waveguide is not kinked, crushed or
bent. Support the Antenna near the ends when lifting it out of its packing and when
fitting into position on the Turning Mechanism. Do Not handle the Antenna by the
Waveguide input.
29 To install the antenna, proceed as follows (refer to Figure 1):
CAUTION
When rotating the Antenna do not apply excessive force.
Ensure the Waveguide, on the underside of the Antenna, is not crushed or damaged.
