Carefully read and follow all safety instructions in this manual
or on pump.
This is the safety alert symbol. When you see this symbol
on your pump or in this manual, look for one of the following
signal words and be alert to the potential for personal injury!
DANGER warns about hazards that will cause seri-
ous personal injury, death or major property damage if ignored.
WARNING warns about hazards that can cause
serious personal injury, death or major property damage if ignored.
CAUTION warns about hazards that will or can
cause minor personal injury or property damage if ignored.
The word NOTICE indicates special instructions which are important but not related to hazards.
To avoid serious or fatal personal injury and possible property
damage, carefully read and follow the safety instructions.
1.
Under certain conditions, submersible pumps
can develop extremely high pressure. Install
a pressure relief valve capable of passing
entire pump flow at 75 PSI.
Do not allow pump, piping, or any other system compo-
nent containing water to freeze. Freezing may damage
system, leading to injury or flooding. Allowing pump or system
components to freeze will void warranty.
2. Can shock, burn or cause death. To avoid
dangerous or fatal electric shock hazard, use
pump only in an effluent system. DO NOT
install pump in an open body of water ( a
lake, swimming pool, etc.).
Install, ground and wire pump according to local and Cana-
dian Electrical Code or National Electrical Code requirements
that apply.
Disconnect electrical power supply before installing or servic-
ing pump.
Make sure motor nameplate voltage and frequency match
line voltage and frequency of power supply.
1. Install pump according to all plumbing, pump and well code
requirements.
2. Install an all leg disconnect switch in the power supply near the
pump.
3. Motors are equipped with automatic thermal overload protection
which will open the circuit and stop the motor when a thermal
overload (excessive heating) exists. When motor cools, overload
will reset and motor will restart automatically.
This can cause the
motor to start unexpectedly and without warning.
GENERAL
Inspect pump and motor for delivery damage. Report any damage
immediately to shipping carrier or to Sta-Rite immediately.
Have any installation, repair, or service work done by your Sta-Rite
dealer.
Never run pump dry.
NOTE: Install pump in the effluent or pumping chamber of vault —
NOT in the sewage chamber. Pump is designed to pump filtered
effluent or clear water only. It is not a sewage pump.
During system operation, pump must be submerged at all times.
Pipe joint compound can cause cracking in plastics. Use only teflon
tape when sealing joints in plastic pipe.
Warranty is void in the following conditions:
• Water is highly corrosive.
• If entrained gas or air present in water being pumped reduce the
flow and cause cavitation (which can damage the pump).
• Pump has been operated with discharge valve closed (severe
internal damage will result).
ELECTRICAL
WIRING/GROUNDING
Can shock, burn, or cause death. Permanently
ground pump, motor and control box before
connecting power supply to motor.
Ground pump and motor in accordance with all codes and ordinances that apply. All wiring must meet National Electrical Code and
Canadian Electrical Code (whichever applies). Use copper ground
wire at least as large as wires carrying current to motor.
Motor is supplied with copper ground wire. Splice to copper conductor that matches motor wire size specified in Table 2. Use only copper wire for connections to pump.
Permanently ground pump and motor before connecting power
cable to power supply. Connect ground wire to approved ground
first, then connect to equipment being installed.
Do not ground to a gas supply line.
Float switches or any other approved motor control must match
motor input in full load amperes.
For more information, contact your local code officials.
INSTALLATION WIRING INSTRUCTIONS
Single Phase, 2 Wire
2-Wire pumps have two power supply wires (Red/Black) and one
ground wire (Green).
1. Fasten power supply wire leads securely to pump discharge section; leave 4-5" of slack in leads at this point. Securely fasten
leads to plastic pipe within 6" of the pump discharge section.
2. Ground wire must be as large as wires supplying current to
motor. Consult current National Electrical Code or Canadian
Electrical Code (as applicable) and local codes for grounding
information.
3. Use only submersible power supply wires supplied by pump manufacturer. When installing pump, secure supply wires to discharge
pipe with Scotch #33 electrical tape. DO NOT damage pump
wires.
NOTICE: To avoid dropping pump or damaging wires or splices,
NEVER allow pump wires to support weight of pump.
EFFLUENT APPLICATIONS
Effluent applications must meet the following:
Risk of electrical shock. Do not remove cord and
strain relief. Do not connect conduit to pump.
1. Only qualified personnel should install the pump and associated
control equipment.
2. Vent sewage tank according to local code.
3. Do not install pump in any location classified as hazardous by
National Electrical Code, ANSI/NFPA 70-1984.
4. These pumps are intended for permanent connection only.
Provide strain relief at control box for power supply cord connection to box. All control components must be UL listed and suitable
for end use application.
PUMP INSTALLATION
1. Make sure that pump and motor are free to rotate by turning the
shaft by hand.
2. To prevent dropping pump, lower it by the drop pipe, not by the
cables. The electrical cables will not hold the pump weight.
3. Discharge outlet is 1-1/4" NPT threaded.
