NT5C06B / C Installation and User Manual

Procedure 21 - Fan replacement ( continued )

Step Action

Remove the four retaining screws which hold the chassis plate, fan and

fan grill together (see Figure 27).

Place the mounting clips on the replacement fan (if it is not so equipped).

Mount the replacement fan in the same orientation as the old one,

ensuring the wire is connected to the fan in the same manner. Ensure the

orientation of the fins is such that the air is blown outwards when the fan

is operated.

Secure the fan, fan grill and chassis plate with the four retaining screws.

Reconnect the fan connector and mount the fan assembly in the unit with

the five mounting screws

Plug the unit back in and power it up. Holding a piece of paper at the front

the unit will confirm that the air is pulled inwards from the front.

Listen carefully for any noise from the fan. It should run free. Verify that

the fan alarm is OFF.

–end–

CAUTION

Verify and ensure that the fan spins freely, without
interference

CAUTION

Do not run the rectifier without a fully operational fan or

with a fan other than the specified replacement for this
cooling application
