MAKE SURE THAT THE APU OIL RESERVOIR IS FILLED BEFORE YOU START THE APU. IF YOU OPERATE THE APU WITHOUT OIL, DAMAGE WILL OCCUR.
(1) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-010). (a) Do the ground air-preconditioning with the APU for a minimum of 10 minutes during the first operation of the APU after its installation.
1 If you smell fumes in the cockpit and/or in the passenger compartment, remove the contamination from the air conditioning system (Ref. AMM TASK 21-00-00-615-802) or (Ref. AMM TASK 21-00-00-615-803) or (Ref. AMM TASK 21-00-00-615-804) and (Ref. AMM TASK 21-00-00-100-001).

O. Inspection of the APU after Shutdown
Make sure that there are no leaks.
(2) Do a check of the magnetic chip detector for unwanted metal (Ref. AMM TASK 49-91-42-200-004).
(3) Do a check of the APU oil level through the oil sight glass. If the oil level is below the full mark, add oil to the full mark (Ref. AMM TASK 49-90-00-600-007).
Subtask 49-11-11-860-072-A ** ON A/C NOT FOR ALL WARNING:
DO NOT TOUCH THE APU UNTIL IT IS SUFFICIENTLY COOL TO PREVENT BURNS WHEN YOU DO THE MAINTENANCE TASK(S).
(1) Carefully examine the APU, the vent and drain valve connections and the drain lines for fuel and/or oil leakage. Make sure that there are no leaks.
(2) Do a check of the magnetic chip detector for unwanted metal (Ref. AMM TASK 49-91-42-200-004).
(3) Do a check of the APU oil level through the oil sight glass. If the oil level is below the full mark, add oil to the full mark (Ref. AMM TASK 49-90-00-600-007).
P. ECS Performance Adjustment
(1) If necessary, you can change the performance adjustment to de-rate mode or original mode (Ref. AMM TASK 49-73-32-600-001).
