AIRSTREAM LAND YACHT GAS
ELECTRICAL:
A. The Aquajet RV pump has a motor speed controller that is factory pre-set to operate at a minimum
current of 10 amps while operating on a 12 VDC system. A 15-amp fuse must protect the
electrical system.
B. The motor speed controller has a built in heat sink. The temperature of this exposed aluminum
surface may reach 200º after extended running.
C. Care must be taken to insure proper connection of the positive wires (red to red), and negative
black wires. Reversing these lead wires will damage the electrical circuit board.
D. The built in pressure sensing demand switch is factory preset to turn off the pump automatically at
65 PSI.
