If the above checklist does not uncover the problem, consult the factory - Do not attempt to service or otherwise disassemble pump.
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.
Submersible pumps contain oils which becomes pressurized and hot under operating conditions - allow 2½ hours after
disconnecting before attempting service.
Maintenance
For your personal safety and health, a high quality

before servicing
GENERAL
Clarus Environmental Centrifugal STEP Systems require periodic maintenance
to remain in operational condition. A qualified service technician should carry
out the required maintenance. These technicians will not only service the pump
unit, but can assess the health of the septic tank.
SERVICE FREQUENCY
• The system contains an effluent filter. This filter will prevent solids larger
than 1/16 ” from entering the pump compartment. The filter will require
cleaning. The cleaning interval is determined by household use patterns.
For example, a single individual may need a filter cleaning and inspection on
yearly intervals, but a family with teenagers may require filter maintenance
every six months, or sooner. The pump tank and pump should be serviced
at a minimum each time the septic tank is pumped. Annual inspections
by trained professionals are recommended.
• Alarm activation between service intervals may be an indication that the
system is not being serviced often enough. The alarm indicates a high
liquid level and service is required immediately to avoid flooding
and sewage back up into the house.
SERVICING THE UNIT
During filter maintenance, the service technician must perform the following:
• Check the sludge level of the septic tank. If the sludge level approaches
the bottom of the STEP vault, the septic tank needs to be pumped.
• The pump should be removed, cleaned, and inspected. Any defective
components should be replaced. Inspect and remove any sand, debris,
or mud present in the pump basin assembly.
• Inspect the panel for any presence of moisture in enclosure, loose
connections, and general component condition.
• Check for proper location and unobstructed float operation.
To remove the entire system:
1. The pump and filter tank must be removed for cleaning and servicing. This
provides an opening for pumping out the septic tank. Remove the riser
ring cover only after disconnecting power to both the pump and alarm.
2. Disconnect the pipe union in the discharge pipe and remove the entire
pump tank assembly. Hose off assembly as it is being removed to avoid
any spillage of sewage or effluents outside the septic tank.
3. Lift assembly out of the riser and stand upright on ground or level working
surface. Remove one of the 1½” support pipes, and then remove lid, pump/
float assembly, and discharge pipe. Place over septic tank opening and
hose down thoroughly. The cordage from the junction box to the pump is
of sufficient length to avoid the necessity of disconnecting the electrical
wiring in the junction box. Do not disturb wiring connection unless pump
is being replaced or repaired. If access is required to the junction box,
disconnect power. Power is disconnected in the Qwik Box by unplugging
the connections.
4. With tank & filter over the opening, hose down the inside and outside tank.
Remove filter pack from tank by pushing on filter pack at the bottom of the
tank through opening or pulling from the top side.
5. Reinstall filter in tank. Check float assemblies for proper operation and
reassemble pump piping and lid on filter tank. Reinstall 1½” support pipe.
Install pump and filter tank back in tank and reconnect union.
6. Fill tank with water and check out the pump system and alarm.
7. Follow Start-up procedures located in the Operation section of this manual
to get system running again.
Service Checklist
CONDITION COMMON CAUSES
A. Pump will not start or run.
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.
B. Motor overheats and trips overload or
blows fuse.
Incorrect voltage, impeller or seal bound mechanically.
C. Pump starts and stops too often.
Float tether length too short, check valve stuck or not installed in discharge line, overload
open, level switch(s) defective.
D. Pump will not shut off.
Debris under float assembly, float or float rod obstructed, switch defective, damaged
or out of adjustment.
E. Pump operates but delivers little or no water.
Check strainer housing on pump and discharge pipe must be open. Discharge head
exceeds pump capacity. Low or incorrect voltage. Incoming water containing air or
causing air to enter pump. Filter Clogged.
F. Drop in head and/or capacity after a
period of use.
Increased pipe friction, clogged line or check valve. Abrasive material and/or adverse
chemicals could possibly deteriorate impeller and pump housing. Check discharge line.
Remove base and inspect pump.
