all safety messages:
WARNING
You will be killed or seriously injured if you don't follow
instructions.
Safety Messages
Safety is important to us. We have included safety messages
throughout this manual and for your protection. Please read and follow
all directions.
A safety message has a safety alert symbol
followed by an explanation of what the hazard
is, what can happen and what you should do
to avoid injury. This is the safety alert symbol:
CAUTION
You can be killed or seriously injured if you don't follow
instructions.

Pump End Assembly
1. Clean and inspect all pump parts (O-ring, seal seats, motor
shaft, etc.).
2. Apply sealant in bracket bore hole and possibly around seal
case according to sealant instructions. For SS seal, chamfer
the edge of the bracket bore hole.
3. Press carbon graphite seal into bracket while taking care not
to damage carbon graphite face.
4. Place slinger (rubber washer) over motor shaft and mount
bracket to motor.
5. Carefully lubricate boot or O-ring around ceramic piece and
press into impeller (if ceramic has O-ring, the marked side
goes in). Use glycerine for EPMD.
6. Sparingly lubricate carbon graphite and ceramic sealing
surfaces. Water, glycerine or a lightweight machine oil may
be used, depending on the elastomers used in the pump.
Do not use silicon lubricants or grease!
7. Thread impeller onto shaft and tighten. If required, remove motor
end cap and use a screwdriver on the back of motor shaft to
prevent shaft rotation while tightening. Replace motor end cap.
8. Electrically, connect the motor so that the impeller will rotate
CCW when facing the pump with the motor toward the rear.
Incorrect rotation will damage the pump and void the warranty!
For 3-phase power, electrically check rotation of impeller with
volute disassembled from bracket. If pump end is assembled
and rotation is incorrect, serious damage to pump end assembly
will occur even if the switch is "quickly bumped." If rotation is
incorrect, simply exchange any two leads.
9. Seat O-ring in volute slot and assembly volute to bracket.
10. Install drain plug with its O-ring in volute drain hole.
Disassembly
WARNING
Shut off power to motor before disconnecting any electrical
wiring from the back of the motor.
1. Disassemble the bracket motor assembly from the volute,
by removing the seven
1/4
" x 2
1/2
" cap screws. (The volute
may be left in-line.)
2. Remove cap covering shaft at back of motor. Using a large
screwdriver, prevent shaft rotation while unscrewing impeller.
3. Remove ceramic piece from impeller.
4. Detach bracket from motor.
5. Remove carbon graphite seal from bracket by pressing
out from the back. Do not dig out from the front!

Maintenance
Lubricate motor per instructions on motor. Rotary seal requires
no lubrication after assembly.
Pump must be drained before servicing or if stored below freezing
temperatures. Periodic replacement of seals may be required due
to normal carbon wear.
Electrical Hookup
ELECTRICAL SHOCK HAZARD
All electrical wiring should meet state and local ordinances.
Improper wiring may not only be a safety hazard but may
permanently damage the motor and/or pump.
1. Check that supply voltages match the motor's requirements.
2. Check motor wiring and connect (according to instructions on motor)
to match supply voltage. Be sure of proper rotation (refer to Pump
End Assembly, #8)! Improper rotation will severely damage pump and
void warranty.
3. Power cord should be protected by conduit or by cable and
be of proper gauge. It should be no longer than necessary.
4. Power should be drawn directly from a box with circuit breaker
protection, or with a fused disconnect switch.
5. Always switch off power before repairing or servicing pump
and/or motor.
Installation
Please read carefully! When properly installed the Sweetwater®pump
will provide dependable, trouble-free service.
1. Locate pump as near the source to be pumped as possible.
A flooded suction situation is preferred. The pump is not self-
priming; therefore, if the fluid level is below the pump, a foot
valve must be installed and the pump primed prior to startup.
2. Mount motor base to a secure, immobile foundation.
3. Use only plastic fittings on both the intake and discharge ports.
Seal pipe connections with PTFE paste. These fittings should
be self-supported and in neutral alignment with each port.
Forcing the fittings into alignment may cause premature line
failure or damage to the pump volute.
4. Never restrict the intake. Keep both input and discharge lines as
free of elbows and valves as possible. Always use pipe of adequate
diameter. This will reduce friction losses and maximize output.
5. This pump is not self-priming and must not be run dry!
We recommend a flooded suction installation.

Troubleshooting
Problem Reason Remedy
Motor will not rotate. Improper wiring.
Breaker/fuse/GFCI tripped.
Overheated motor.
Check for proper electrical connections to motor.
Check main power supply for tripped breaker, etc.
Check thermal overload on motor.
Motor hums or will not rotate at correct speed. Improper wiring.
Debris in impeller/volute.
Mechanical resistance to rotation.
Bearing problem.
Failed condenser/start switch.
Check for proper electrical connections and proper
cord size and length.
Check for foreign material inside pump.
Remove motor and check for impeller rotation without
excessive resistance.
Remove motor and check shaft rotation for excessive
bearing noise.
Have authorized service person check condenser.
Pump operates with little or no flow. Pump not primed.
Seal leak.
Improper line voltage.
Improper phase rotation.
Obstruction in plumbing/impeller.
Defective check or foot valve.
Air introduction in inlet plumbing.
Check to insure that pump is primed.
Check for leaking seal.
Check voltage.
Check phase rotation.
Check for clogged inlet port and/or impeller.

Check inlet lines for air leakage.
Pump loses prime. Defective check or foot valve.
Seal leak.
Air introduction in inlet plumbing.
Fluid supply low.
Inspect check/foot valve for obstruction or failure.
Check for leaking seal.
Check inlet lines for air leakage.
Ensure proper sizing of pump for available
fluid supply.

Deadheaded pump.
Check amperage, voltage, and phase.
Check for obstruction, bearing failure,
shaft distortion.
Allow for airflow around pump motor.
