14-volt aircraft
- a three-position switch :
LO = low flow (maximum endurance : approximately 2 hr 10),
OFF = stop,
HI = high flow (maximum endurance : approximately 1 hr 35),
- a yellow warning light, on R.H. side of the switch, which flashes when the system operates.
A fuse, located on PL1 circuit breaker panel or on inspection door 212L (fuse printed circuit) protects the circuit.
28-volt aircraft
- a three-position switch :
LO = low flow (maximum endurance : approximately 2 hr 10),
OFF = stop,
HI = high flow (maximum endurance : approximately 1 hr 35),
