1.1 General
The electric motors (4, Fig. 1) operate the two auxiliary blowers (2), which are
installed on the scavenge air receiver (3). The auxiliary blowers supply air from the air
space through the duct (1) into the receiver space during the engine start and
operation at low load. Flaps prevent the back-flow of air to the scavenge air receiver
(see 6420-1 Scavenge Air Receiver).
Note: If the auxiliary blower does not operate for a long period, do the
procedure given in 0620−1 Prepare the Engine for a Long Shutdown
Period, paragraph 2.2 Procedures and Checks.
