Installation and Operation Manual
Power-Fill System
Provide adequate electrical power (41 amps @13.5V DC, 21 amps @ 27V DC) from the battery. Use 8
AWG wire directly from the battery or battery switch. Long wire runs will require a larger gauge wire for
proper operation. Use the following as guidelines for longer wire runs.
Electrical devices can be easily damaged by a weak or erratic power supply. The Power-Fill system is no
different - the better the power supply, the better the system will perform.
DO NOT
connect the main power to leads that supply power to some other device, such as a light bar,
siren, or primer pump.
Do not attach the red power wire to the hot side of the solenoid. Power and
ground for the controller needs to come from a separate power source
.
NOTE: Any system without a flow switch will require Jumper 2520-0118 or system will shut down
automatically after 20 seconds.
