and may restart unexpectedly. Protector tripping is an indication of motor
overloading as a result of operating the pump at low heads (low discharge
restriction), excessively high or low voltage, inadequate wiring, pumping
too hot a liquid, incorrect motor connections, or a defective motor or pump.
Read troubleshooting chart.
8. Do not touch an operating motor. Modern motors are designed to operate
at high temperatures.
9. Provide adequate protection and guarding around moving parts. Secure
the discharge line before starting the pump. An unsecured discharge line
will whip, possibly causing personal injury and/or property damage.
10. Check hoses for weak or worn condition before each use, making certain
that all connections are secure.
11. Periodically inspect pump and system components. Perform routine maintenance
as required (see SERVICE INSTRUCTIONS).
12. Provide a means of pressure relief for pumps whose discharge line can be
shut-off or obstructed.
13. PERSONAL SAFETY: Wear safety glasses at all times when working with pumps.
14. Do not add acid or electrolyte to a battery being used – add only water.
Consult the battery manufacturer for any additional safety instructions
Electrical Connection
1. Make certain that power source conforms to the requirements of your equipment.
2. When wiring an electrically driven pump, follow all electrical and safety
codes, as well as the most recent National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA) in the United States.
3. Model 360 and 370 are only for use on 115 volt (single-phase) and is
equipped with an approved 3-conductor cord and 3-prong, grounding-type
plug. Model 365 is for 12VDC.
4. To reduce the risk of electric shock, models 360 & 370 should be plugged
directly into a properly installed and grounded 3-prong grounding-type receptacle.
The green (or green and yellow) conductor in the cord is the grounding
wire. The motor must be securely and adequately grounded for your protection
against shock hazards! Never connect the green (or green and yellow)
wire to a live terminal! SEE SECTIONS 10, 11 & 12 FOR MODEL 365.
5. Where a 2-prong wall receptacle is encountered, it must be replaced with
a properly grounded 3-prong receptacle installed in accordance with the
National Electrical Code and local codes and ordinances.
6. To ensure a proper ground, the grounding means must be tested by a
qualified electrician. Use only 3-wire extension cords that have 3-prong,
grounding-type plugs and receptacles that accept the equipment plug.
7. All wiring should be performed by a qualified electrician.
8. Protect electrical cord from sharp objects, hot surfaces, oil and chemicals. Avoid
kinking the cord. Replace or repair damaged or worn cords immediately.
9. When using an extension cord make sure wire is of adequate size to minimize
voltage drop at the motor. For models 360 & 370, 16 AWG is OK up to 40'.
Distance From Power Source To SST Pump Recommended Wire Size
1 - 12 Ft. #14
13 - 24 Ft . #12
25 - 36 Ft. #10
10. The SST Pump is not equipped with an inline fuse. Because of the
wide variety of applications and mounting situations, an inline fuse has not
been permanently installed. In order to provide adequate protection for the
motor, an inline fuse and fuse holder MUST be installed. The model 365
pump warranty does not cover motor damage caused by overheating. For
maximum protection, a fuse of 7 amps is suggested. Fuses and fuse holders
are readily available in most hardware, auto and home improvement stores.
11. GENERAL CONNECTION INFORMATION to a 12VDC battery.
a. Connect POSITIVE or PLUS (+) lead from the pump to battery first.
POSITIVE lead of pump is red.
b. If pump is to be connected to battery that is installed in a vehicle, connect
NEGATIVE or MINUS (–) lead to a ground away from the battery,
