The alarm may be difficult to hear if machinery is running in the engine room.
3. At the control panel, set the ON/OFF switch (figure 3, item 1) to the ON position. When first turned ON, the
alarm will self-test. During this self-test, the alarm light (figure 4, item 1) will illuminate and the audible alarm
(figure 4, item 2) will sound. The self-test will conclude and the alarms will secure after 3-5 seconds. If the
self-test does not function as described above, troubleshoot the alarm (WP 0008 00).

4. Start the desired fuel transfer pump (TM 55-1925-273-10) to begin transferring fuel.
5. Observe the readings on the inlet pressure gauge (figure 4, item 3) and discharge pressure gauge (figure 4,
item 4). If the differential pressure between these gauges exceeds 10 PSI (0.7 bar) or 10 inHg (254 mmHg),
secure from fuel transfer and change the filters (WP 0013 00). If it is necessary to transfer fuel while
changing the filters, bypass the fuel filter/water separator (WP 0006 00) to permit continued transfer of fuel.
6. Continue operation of the fuel filter/water separator until fuel transfer is complete or until the differential
pressure readings exceed the value given in step 5 above. When fuel transfer is complete, shut down the
fuel filter/water separator as described in the paragraph below.
