Limited Warranty

This product is warranted for one year from the date of purchase. Subject to the conditions hereinafter set forth, the manufacturer will repair or replace to the original consumer, any portion of the product which proves defective due to defective materials or workmanship. This warranty does not cover replacement parts for failure due to normal wear and tear. To obtain warranty service, contact the dealer from whom the product was purchased. The manufacturer retains the sole right and option to determine whether to repair or replace defective equipment, parts or components. Damage due to conditions beyond the control of the manufacturer is not covered by this warranty.

THIS WARRANTY WILL NOT APPLY:

To defects or malfunctions resulting from failure to properly install, operate or maintain the unit in accordance with printed instructions provided;
to failures resulting from abuse, accident or negligence or use of inappropriate chemicals or additives in the water;
to normal maintenance services and the parts used in connection with such service;
to units that are not installed in accordance with normal applicable local codes, ordinances and good trade practices; and
if the unit is used for purposes other than for what it was designed and manufactured.

In those instances where damages are incurred as a result of an alleged pump failure, the Homeowner must retain possession of the pump for investigation purposes.

Preinstallation Information

Inspect your unit. Occasionally, products are damaged during shipment. If the unit is damaged, contact your dealer before using.
Carefully read the literature provided to familiarize yourself with specific details regarding installation and use. These materials should be retained for future reference.
Warning: “Risk of electrical shock” Do not remove power supply cord and strain relief or connect conduit directly to the pump. Installation and checking of electrical circuits and hardware should be performed by a qualified and licensed electrician.
Warning: Do not lift, carry, or hang pump by the electrical cables. Damage to the electrical cables can cause shock, burns or death.
Warning: 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 qualified licensed electrician.
Warning: 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 sufficient 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.
Warning: Make sure the pump electrical supply circuit is equipped with fuses or circuit breakers of proper capacity. A separate branch circuit is recommended and sized according to the “National Electrical Code” for the current shown on the pump nameplate.
Warning: DO NOT run the pump dry. DO NOT run the pump with a completely closed discharge. DO NOT pump chemical or corrosive liquids. Failure to follow above warnings could result in damage to the pump, voiding the warranty and causing personal injury.
Caution: Check to be sure your power source is capable of handling the voltage requirements of the motor, as indicated on the pump nameplate.
The installation of pumps using auxiliary variable-level float switches is the responsibility of the installing party. Care should be taken such that the tethered float switch will not hang up and are secured so that the pump will turn on and off properly.
Caution: 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 springs or lever-weighted check valves or other engineered solutions.
Caution: 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-flow from the discharge line.

Major Components

Submersible Effluent Turbine Pump – A submersible effluent turbine pump is a multistage centrifugal design pump. Each stage consists of an impeller and diffuser. Water pressure increases in equal amounts as it passes from stage to stage. The more stages, the higher the pressure the pump will develop.
To correctly select a pump for a specific application, the following information must be known:
- The amount of discharge required in GPM or LPM
- The total dynamic head required in feet or meters
  Use this information along with the performance data found on the previous page to make your selection.
Control Panel – Submersible effluent turbine pumps require the use of an above ground control panel or junction box with a pump control switch for proper operation. Operation of these pumps without a control panel or junction box with a pump control switch can result in failure of the pump and void the warranty.
Float Switches – All submersible effluent turbine pumps are nonautomatic. The use of float switches are required for the proper operation of the pump. Operation of these pumps without float switches can result in failure of the pump and void the warranty.
A minimum of two float switches should be used in each application:
- A pump control float switch
- A high water alarm float switch
Piping – The submersible effluent turbine pump can be installed with schedule 40 PVC pipe. The pipe size should be 1¼” diameter for the 10 GPM to 27 GPM pump series and 2” diameter for the 35 GPM pump series.
General piping from the pump to a splitter, distribution box, drain field etc., should be the same diameter as stated above. For long pipe runs consult friction loss tables for correct pipe sizing.
Check Valve – A check valve is required in all duplex systems. It is also required when a large amount of effluent can backflush into the system causing rapid cycling of the pump. A 1/8” weep hole must be drilled in the side of the discharge head when using a check valve (see drawing below for drill location).

Pump Installation and Wiring Diagram

Submersible effluent turbine pumps may be installed in any application where relatively clear effluent, such as from a dosing tank or high head STEP system etc., is being pumped.
Pumps should always be installed vertically. Pumps should never be installed horizontally.
Because of their low-temperature rise, pumps under 2 HP do not require a flow inducer sleeve.
Mount the junction box in its permanent position.
Run prewired conduit, or equivalent submersible cable from the junction box to a fused disconnect or, if applicable, the control panel.
Feed the pump power cord and float switch cords into the junction box.
Make the connections in the junction box using the wiring diagrams below. If you are using a control panel or a filtered STEP system, follow the wiring diagrams and instructions included with them.
An alarm should be used with any system using a pump. Follow the wiring diagram with the alarm for installation and check your local codes.
Run the appropriate power to the control panel from a fused (circuit breaker) disconnect. The appropriate power supply information may be found on the pump nameplate.
To provide a suitable ground, a separate ground wire (green or bare) at least as large as the line conductors is required. It is connected from the electrical disconnect box to the control panel, to the junction box and to the green ground wire of the submersible motor lead.
Always disconnect all power when installing or servicing the pump. $Flint-Walling-Effluent-Turbine-Submersible-Pumps-fig- $7$$

Splicing Underground Wires

Splicing of wires to be buried must be done according to the National Electrical Code. Wire connectors or splicing means installed on conductors for direct burial shall be listed for such use.

Start-up and Maintenance

Before placing the equipment into operation the following must be checked:

The septic tank and/or pump chamber should be pumped and cleaned prior to installation in the existing system.
The 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.
The 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 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 have been completed 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.

Troubleshooting and Service Checklist

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.

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 over- load or blows fuse.| Incorrect voltage, negative head (discharge open lower than normal), impeller or seal bound mechanically, or relay, motor shorted.
C. Pump starts and stops too often.| Check valve stuck or none installed in long distance line, overload open, level switch(es) defec- tive, sump pit too small, leak in the system.
D. Pump will not shut off.| Debris under float assembly bound by pit sides or other, switch defective, damaged or out of adjustment, leak in the system.
E. Pump operates but delivers little or no water.| 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.
F. Drop in head and/or capacity after a period of use.| 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.
If the above checklist does not uncover the problem, consult the factory – Do not attempt to service or otherwise disassemble pump. Service must be by Flint & Walling Authorized Service Stations.
