FUEL SYSTEM (CONTINUED)
The Auxiliary Power Unit (APU) and personnel heater receive fuel
through the fuel inlet tee connection from the fuel distribution ter-
minal. APU pumps become operational when the MASTER switch
located on the APU control panel is turned ON. Fuel is delivered to
the APU compartment wall-mounted filters and on to the APU. Ex-
cess fuel is routed through the fuel return line to the fuel cells.
The personnel heater fuel pump becomes operational when the per-
sonnel heater MASTER switch is turned ON. Fuel is routed to the
personnel heater filter and onto the heating unit.
