Some states do not allow limitations on the duration of an implied warranty, so the above limitation may not apply to you. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

This warranty gives you specic legal rights and you may also have other rights

which vary from state to state.

Preinstallation Information

1. Inspect your unit. Occasionally, products are damaged during shipment.

If the unit is damaged, contact your dealer before using.

2. Carefully read the literature provided to familiarize yourself with specic

details regarding installation and use. These materials should be retained

for future reference.

3. Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical cables can cause shock, burns or death.

4. For your protection, make certain the pump

ground wire is properly connected to the ground wire with the incoming power line. Test for ground at the junction box using

an Underwriters Laboratory listed circuit analyzer which will indicate if the power, neutral and ground wires are correctly connected. If in doubt, call a

qualied licensed electrician.

5. Make certain that the receptacle is within

the reach of the pump’s power supply cord. DO NOT USE AN EXTENSION CORD. Extension cords that are too long or too light

do not deliver sufcient voltage to the pump motor. But, more important, they

could present a safety hazard if the insulation were to become damaged or the connection end were to get wet.

the voltage requirements of the motor, as indicated on the pump nameplate.

Check to be sure your power source is capable of handling

7. Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers of proper capacity. A sepa-

rate branch circuit is recommended, and sized according to the “National Electrical Code” for the current shown on the pump nameplate.

The installation of pumps using auxiliary variable level

oat switches is the responsibility of the installing party and care should be taken that the tethered oat switch will not hang up on the pump ap-

paratus or pit peculiarities and is secured so that the pump will shut off.

9. Water hammer creates momentary high pressure surges. These surges can cause severe damage to check valves and the piping system. Consideration for water hammer must be included in the piping system design. Reference ASPE Data Book, Chapter 2.33. Some systems may require external spring or lever weighted check valves or other engineered solutions.

10. In cold climates the discharge pipe may be subject to freezing. If the riser on the septic tank is above the frost line, it will be necessary to protect the system from freeze up. The discharge pipe can be insulated or the check valve can be removed. If the check valve is

removed, the “on-off” cycle must be adjusted for any back-ow from the

discharge line.

System Installation Instructions

1. Clarus Environmental Centrifugal STEP Systems are designed for installation in septic tanks through the riser on the discharge end of the tank. See Fig. 1. If a complete system has been purchased,

all the components will be included except external pipe, ttings,

and riser. Check your Local Code for alarm requirements.

2. All installations must comply with all applicable electrical and plumbing codes, including, but not limited to, National Electrical

Code, local, regional, and/or state plumbing codes, etc.

3. If the Clarus Environmental Centrifugal STEP System is being

retrotted into an existing septic system, it will be necessary

to pump and clean out the septic tank before installing. Before pumping, measure down to the liquid level in the septic tank (not the scum layer) from the septic tank lid and record. The septic tank lid becomes the reference point for measuring to correctly

install your system. Take the proper measurements before attempting

to install the new ltered pump system.

4. The outlet pipe is typically 3” below the inlet on a conventional gravity system. Check the dimensions from the top of septic tank to the bottom of the inlet and outlet pipe. Each individual system varies therefore do not assume your system is 3”.

5. An 18” hole is required in the top of the septic tank to install the STEP system. If the hole in your septic tank is less than 18”, provisions must be made to open the hole up to 18”. (You may have to change the lid of the septic tank.)

6. If your system is not equipped with a riser, install a new Clarus Environmental 24” or 30” diameter riser. Follow the installation instructions provided with the riser.

System Installation Instructions, continued

7. Bring piping from the lateral eld to the outside of the riser on the

septic tank. Note: If installing a system using a control panel follow the instructions included with the panel and skip steps 11-12 and 15.

8. Disconnect Clarus Environmental exible pipe assembly at union

on ball valve. Install pipe seal through the riser wall (2” hole saw

required) to prevent ground water intrusion. Install exible pipe

through pipe seal with union ball valve on inside of riser as shown

in Figure 1A. Solvent weld exible pipe to lateral eld piping using

PVC pipe cement.

9. Connect other part of 1 ¼” discharge pipe assembly to pump outlet with pump setup outside the pump tank.

10. Tie off power cord by strapping to the discharge pipe. Make certain the cord cannot become entangled or obstruct the movement of the floats.

11. Install wire from power source and the alarm. See Fig. 1A or 1B. If a junction box is being used, Fig. 1A, install inside the septic tank riser. If a Qwik Box System is being used, Fig. 1B, install outside of septic tank riser as shown in Fig. 1B or inside of septic tank riser. Note: Some codes require the junction box to be outside the riser.

12. Install pump switch on discharge pipe using the included band clamp. Place the band clamp as low on the discharge pipe as possible.

Tether the pump switch so that 3.5" of cord exists between the oat

and the clamp. This will yield a 7" drawdown cycle. Additional tethers can be used if state, local and regional codes permit.

ground wire is properly connected to the ground wire with the incoming power line. Test for ground at the junction box using

an Underwriters Laboratory listed circuit analyzer which will indicate if the power, neutral and ground wires are correctly connected. If in

doubt, call a qualied licensed electrician.

13. Measure length of hanger pipes by measuring inside the riser. Cut and

install hanger pipes in lter tank and lower the assembly into the septic

tank opening. Tie off power cords by strapping to discharge pipe. Make certain cords cannot become entangled or obstruct the movement of the

oats. See Fig. 1. Lower pump with discharge pipe and oat assemblies into lter tank.

14. Adjust piping using threaded elbows and exible piping provided to achieve proper t. Connect union on ball valve.

15. Install the alarm inside the house or in a weather protected location per installation instructions with alarm kit, making sure the alarm is plugged into a different circuit than the pump circuit. Complete the wiring connections. If a junction box is being used, Fig. 1A, wire per diagram in Fig. 4. If a Qwik Box outside connection is being used, wire according to the installation instruction provided with the Qwik Box unit. All wiring, from the power source to the pump, must conform to the National Electrical Code. Be

sure to leave a sufcient amount of cord so the lter can be serviced

without disconnecting the cordage from the junction box or Qwik box. See Maintenance section on back page.

16. Fill the septic tank with water and check the alarm level before placing the system into service. See operation and start-up areas of this manual.

Timed Dosing Applications

Clarus Environmental Centrifugal STEP Systems are adaptable for Timed Dosing Applications using the following recommendations.

• Refer to Clarus Environmental Centrifugal STEP Systems catalog

sheet (CL0031) and Clarus Environmental Timed Dosing Panels catalog sheet (CL0107) for ordering the correct panel part number.

• If the system is dosing a collection system, draineld, sand lter,

wetland, or some other secondary wastewater treatment system, the ideal dosing pattern should be known and applied.

Operation

GENERAL

The centrifugal septic tank effluent pumping (STEP) system is designed to be an easily installed, drop in pump basin that does not require an additional pump chamber. However it can be installed in a secondary pumping chamber. By using a submersible pump, high head pressures are achieved. The system was designed for convenience. The filters are easily removed for servicing.

The filter has 528 linear feet of 1/16” filtration. This large surface

area ensures adequate filtering, and a longer interval between necessary servicing.

SHORT TERM STORAGE

If unit is to be stored for six months or longer:

• Store system inside whenever possible or cover with some type of

protective covering

• Store unit upright in original shipping container

• Ideal storage temperatures are 45 to 90 degrees

• Tape or seal in a plastic bag the terminal ends of the wire leads

• The alarm must be activated before the efuent level reaches the

bottom of the existing outlet pipe. The alarm can be set higher, up to the bottom of the inlet pipe, if the existing outlet pipe has been plugged. This can be determined by measuring the location and elevation of the discharge pipe.

• Filling the septic tank with water after completion of the installation

must be done in order to check the pump and alarm.

the pump and check valve to insure the pump will not airlock

• If a control panel is used, the panel must be dry and securely installed

Fill the septic tank with water and check the system operation before placing into service.

After installing the pump into the containment area with adequate submergence, open the discharge valve fully. Start the unit using manual

controls. If ow 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 qualied 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 of 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 have been completed before placing the system into service.

If panel is to be stored for more than six months, the following is advised:

• Store the panel inside whenever possible and leave in the shipping box

• All openings must be sealed

• Store in an upright position

• Do not stack anything on top of panel

START-UP

Before placing the equipment into operation the following must

be checked:

• Septic tank should be pumped and cleaned prior to installation in existing system

• 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

• Floats need to be in place, secure and adjusted for proper cycling

• Make sure oat switches are free to move within the basin

•

Be sure electrical connections are watertight and conform to uniform building codes

• When a check valve is used, drill a 3/16” vent hole in pipe, between

OPERATION

• If the system is dosing a collection system, draineld, sand lter,

wetland, or some other secondary wastewater treatment system, the ideal dosing pattern should be known and applied.

• The high water alarm will indicate the system needs maintenance. However, regular maintenance by trained professionals is a necessary part of operation.

• During operation, the system owner must continue to use proper septic tank ownership practices. Ground garbage, hair, grease, and

non-ushable paper products should be prevented from entering any

septic system. These materials will be prevented from entering the

draineld by the lter apparatus, but abuse of the system will result

in the need for more frequent servicing.

Maintenance

For your personal safety and health, a high quality pair of rubber gloves are recommended while servicing this unit. For your personal health, always wash your hands with antibacterial

soap after servicing this unit.

Always disconnect pump and panel from its power source

before servicing

GENERAL

Clarus Environmental Centrifugal STEP Systems require periodic maintenance

to remain in operational condition. A qualied 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 efuent lter. This lter will prevent solids larger than 1/16” from entering the pump compartment. The lter will require

cleaning. The cleaning interval is determined by household use patterns.

For example, a single individual may need a lter cleaning and inspection on yearly intervals, but a family with teenagers may require lter 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 ooding

and sewage back up into the house.

SERVICING THE UNIT

During lter 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 oat operation.

To remove the entire system:

1. The pump and lter 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 efuents 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/ oat assembly, and discharge pipe. Place over septic tank opening and

hose down thoroughly. The cordage from the junction box to the pump is

of sufcient 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 & lter over the opening, hose down the inside and outside tank. Remove lter pack from tank by pushing on lter pack at the bottom of the

tank through opening or pulling from the top side.

5. Reinstall lter in tank. Check oat assemblies for proper operation and reassemble pump piping and lid on lter tank. Reinstall 1½” support pipe. Install pump and lter 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.
