SMART SENSOR 5.7 Installation & Operation Manual

IMPORTANT

READ INSTRUCTIONS ENTIRELY BEFORE INSTALLING THE SMART SENSOR 5.7

Congratulations! You have purchased the finest fresh water pump in the industry. The Smart
Sensor 5.7 has been designed and engineered to provide you with “just like home” water flow.

MOUNTING

• Mount pump within 6 feet of tank for best performance.

• Mount pump for easy access if maintenance is required.

• Mount pump in a space of one cubic foot unless adequate ventilation is provided.

• The pump may be mounted in any position.

• Choose a solid surface that will not amplify pump vibration. Heat sink must be free and

have air flow across.

• The mounting feet are intended to isolate the pump from the mounting surface;

over tightening, or use of oversized screws will reduce ability to isolate vibration/noise.

ELECTRICAL

• The pump should be on a dedicated (individual) circuit protected by the specified fuse

indicated on the motor label.

• A U/L approved marine duty switch (ignition protected) rated for 15 amps or higher is

recommended, and must interrupt current flow on the positive (+ red) lead.

• Pump draws 15 milliamps when pump switch is on, even when pump is not running.

WARNING: 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

SCREW

Reducing unnecessary restrictions to the inlet and the outlet tubing will allow the pump to run freely, maximizing the
Smart Sensor’s performance, quietness and eliminate the possibility of cavitation (starving the pump).

OPERATION & SHUT-OFF ADJUSTMENT

Pump cycling may be caused by excessive back pressure created by one or more of the following within a plumbing system:

• Low flow from partially open faucet.

• Water filters not on separate feed lines.

• Clogged water filters.

• Restrictive elbows shut-off and check valves

• Use as few elbows and valves as possible in the first two feet [.6M] after the pump.

• Flow restrictors in faucets and showerheads.

• Long lengths of small I.D. lines.

• Pipe/tubing should be at least 1/2” [13mm] I.D. from main lines.

• Restrictive fittings and connections (elbows, “T’s”, feeder lines to faucet etc.)

If the pump is cycling rapidly increase the setting by turning the screw clockwise (1/2 to 3/4 turn MAX.) If the pump continues to
cycle after making the pressure adjustments contact SHURflo customer service.

• Installation of a 40 mesh strainer, such as SHURflo model 254 is recommended to prevent debris from entering the pump.

• SHURflo recommends at least 1ft. [.3 M] of ½" [13mm] I.D. flexible high pressure tubing to both ports. Ideally, the pumps ports

and strainer should not be connected to plastic or rigid pipe. The pump's normal oscillation may transmit through rigid
plumbing causing noise, and possibly loosen or crack components.

• 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.

• Pump may flow better with 3/4” line feeding the pump.

FITTINGS INTALLATION INSTRUCTIONS

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.
