(c)  
Install a cap on the electrical receptacle of the APU fuel shutoff valve.

(d)  
Attach the cap chain to the receptacle attachment screw.

D.  Deactivate air inlet door (Fig. 802).
(1)  FOR THE C49001 TOOL KIT;
If the inlet door actuator does not operate correctly, do the deactivation of the air inlet door with the actuator removed:
(a)  
Remove the inlet door actuator (Ref 49-15-31 R/I).

(b)  
Install the cap for the electrical connector for the inlet door actuator.
