HIGH FLOW SMART SYSTEM
INSTALLATION AND OPERATION INSTRUCTIONS
MODEL #: 5907-5304 (12V)
MODEL #: 5907-6304 (24V)
IMPORTANT
READ INSTRUCTIONS BEFORE INSTALLING THE HIGH FLOW SMART SYSTEM
Congratulations! You have purchased the finest fresh water dual pump system in the industry.
The High Flow Smart System has been designed and engineered to provide you with “just like
home” water flow up to 10 gallons per minute.
MOUNTING
• Mount system within 6 feet of tank for best performance.
• Mount system for easy access if maintenance is required.
• Mount system in a space of one cubic foot unless adequate ventilation is provided.
• The system may be mounted in any position.
• Choose a solid surface that will not amplify the system vibration.
• The mounting feet are intended to isolate the pump from the mounting surface; over
ELECTRICAL
• The pumps should be on a dedicated (individual) circuit protected by the specified fuse
indicated on the motor label. NOTE: If both pumps are installed on the same circuit
be aware of the total current generated by both pumps. Use the appropriate fuse size
and wire gauge to protect both pumps (Total current draw x 113% = fuse size).
See flow curve on page #2 for reference.
• A U/L approved marine duty switch (ignition protected) is recommended, and must interrupt
current flow on the positive (+ red) lead.
• Smart Sensor 5.7 pump draws 15 milliamps when pump switch is on, even when pump is not
running.
WARNING: SMART SENSOR 5.7 12V PUMPS
Test incoming power with a multimeter to check voltage polarity (red = +). Red pump wire
MUST be connected to positive power or permanent damage to controller will result!!! Failures
of these type are not covered under product warranty.

PLUMBING
Reducing unnecessary restrictions to the inlet and the outlet tubing will allow the
system to run freely, maximizing performance, quietness and eliminate the possibility
of cavitation (starving the pumps).
• Installation of a 40 mesh strainer to each pump, such as SHURflo model 254 is
recommended to prevent debris from entering the pumps.
• SHURflo quick-connect fittings provide easy installation and removal if required. The fittings
are designed with dual o-rings, creating a seal when snapped into place.
• System may flow better with 3/4” line feeding the pumps.
