ELECTRICAL PRECAUTIONS- Before servicing a pump, always shut off the main power breaker and then unplug
the pump - making sure you are not standing in water and wearing insulated protective sole shoes. Under flooded conditions, contact
your local electric company or a qualified licensed electrician for disconnecting electrical service prior to pump removal.
If the above chart does not uncover the problem, consult Clarus Environmental - Do not attempt to service or otherwise disassemble unit.
Troubleshooting and Service Checklist
COMMON CAuSES
Check fuse, low voltage, overload open, open or incorrect wiring, open switch, impeller
or seal bound mechanically, defective capacitor or relay when used, motor or wiring
shorted. Float assembly held down. Switch defective, damaged, or out of adjustment.
Incorrect voltage, negative head (discharge open lower than normal), impeller or seal
bound mechanically, or relay, motor shorted.
Check valve stuck or none installed in long distance line, overload open, level switch(es)
defective, sump pit too small, leak in the system.
Debris under float assembly bound by pit sides or other, switch defective, damaged
or out of adjustment, leak in the system.
Check strainer housing, discharge pipe, or if check valve is used vent hole must be
clear. Discharge head exceeds pump capacity. Low or incorrect voltage. Incorrect
motor rotation. Capacitor defective. Incoming water containing air or causing air to
enter pumping chamber.
Increased pipe friction, clogged line or check valve. Abrasive material and adverse
chemicals could possibly deteriorate impeller and pump housing. Check line. Remove
unit and inspect.
CONDITION
A. Pump will not start or run.
b. Motor overheats and trips overload or
blows fuse.
C. Pump starts and stops too often.
D. Pump will not shut off.
E. Pump operates but delivers little or no
water.
f. Drop in head and/or capacity after a
period of use.
Start-up and Maintenance
Before placing the equipment into operation the following must be
checked:
• Septic tank and/or pump chamber should be pumped and
cleaned prior to installation in existing system.
• Septic tank and/or pump chamber must be watertight.
• Installation needs to be according to instructions.
• Installation should include an easy access riser and tamper
resistant lid.
• Filter assembly needs to be in place and secure.
• Float tree needs to be in place, secure and adjusted for proper
cycling.
• Make sure float switches are free to move within the basin.
• Be sure electrical connections are watertight and conform
to the Uniform Building Code and the National Electrical
Code (NEC).
• Fill the septic tank and/or pump chamber with water and check
the system for operation.
After installing the pump into the containment area with adequate
submergence, open the discharge valve fully. Start the unit using
manual controls. If flow is appreciably less than rated performance,
pump may be air locked. To expel trapped air, jog the unit several
times, using the manual controls.
Have a qualified electrician take voltage and current
measurements on the black wire of single phase. Record these
readings in the space provided in the “Owner’s Information” section
on the front this manual for future reference.
Be sure to complete all items such as installing the lid on the
riser, securely closing the control panel, and checking the system
operation before placing the system into service.
Routine maintenance should include:
• Service filter in STEP system and/or septic tank.
• Clean pump screen.
• Make sure the check valve is functioning properly.
• Check wire connections.
• Make sure the weep hole is clear.
• Make sure the float switches are free to move within the basin.
• Make sure there are no leaks in the plumbing.
• Make sure there is no excessive noise while the pump is
running.
