To replace a frame ventilation fan
1 Procure a replacement fan assembly. It is
comprised of a fan and an attached circuit
board. It is available from Grass Valley as
part #0969-2100.
2 Remove the two screws that secure the fan assembly to the frame and pull the fan
assembly straight out of the frame.
3 Retain the screws, as they will be used to install the replacement fan assembly.
4 Slide the new fan assembly into the opening on the rear panel, pushing it straight in
and ensuring that the connector on the assembly mates with the socket in the frame.
NOTE: the two ventilator fans are mounted at different
angles, as shown in the above figure. Align the circuit
board on the fan assembly with the notches in the edge
of the rear-panel opening (see arrows in figure at right) to
ensure the correct alignment.
The socket into which the circuit board connects is
hidden from view by the fan assembly during installation
and there is no guide to ensure that they are aligned. The
easiest way to make sure that the connector and socket
have mated properly is to install the fan with the frame
power turned on. You will hear the fan start up when the
connection is made.
5 Use the two screws that were retained when the old fan assembly was removed to
secure the new fan assembly to the rear panel.
