Safety Information
Read these warnings carefully. Know the application and limitations of this pump. Failure to follow these warnings could result in serious bodily injury and/or property damage.
DANGER RISK OF ELECTRICAL SHOCK. Disconnect and lockout power supply before removing old pump or installing or servicing this pump. a DANGER RISK OF ELECTRICAL SHOCK. This pump is supplied with a grounding conductor and grounding type attachment plug. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, grounding type receptacle. For added safety, it is highly recommended to connect this pump to a GFCI (Ground Fault Circuit Interrupter) outlet. Connect only to a receptacle that is adequately rated for the voltage and amperage of this pump.
WARNING The installation of this pump must be in accordance with the National Electric Code (NEC), Uniform Plumbing Code (UPC), International Plumbing Code (IPC) as well as all applicable local codes and ordinances.
CAUTION Do not install this pump in any location classified as hazardous by the National Electrical Code, ANSI/NFPA70.
CAUTION Do not use this pump to pump flammable or explosive fluids such as gasoline, kerosene, etc. Do not use this pump in flammable or explosive environments. Use only with liquids compatible with pump component materials.
WARNING RISK OF ELECTRICAL SHOCK. This pump has not been investigated for use in swimming pool or marine areas.
WARNING Sewage pumps handle materials that can cause illness or disease. Wear protective clothing when installing or servicing a pump in an existing
WARNING RISK OF ELECTRICAL SHOCK. DO NOT use the power cord to remove or lower the pump into the basin. The cord may pull apart exposing bare wires which could cause a fire or electrical shock. Use the handle supplied with the pump for installing and removing the pump from the basin.
WARNING Do not run the pump dry. This pump relies on water for cooling. Running the pump dry can cause the pump to overheat and the possibility of burns to anyone that handles the pump. Running the pump dry will void the warranty.
WARNING If entry into a septic basin is necessary use proper OSHA safety procedures. Do not enter the basin until those procedures are adhered
WARNING Do not use this pump for potable/drinking water. Use only in applications for which the pump is designed for.
DANGER TO PREVENT RISK OF EXPLOSION. Do not smoke, use flames or electrical devices that could emit sparks in a septic/sewage environment as sewage/septic fumes could be explosive.
WARNING According to the state of California (Prop 65), this product contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.
WARNING DO NOT UNDER ANY CIRCUMSTANCES REMOVE THE GROUND PIN. The 3-prong plug must be inserted into a mating 3-prong grounded receptacle. If the installation does not have such a receptacle, it must be changed to the proper type, wired and grounded in accordance with the National Electrical Code and all applicable local codes and ordinances.
WARNING All wiring must be performed by a qualified electrician.
WARNING Keep hands clear of suction & discharge openings. To prevent injury, never insert fingers into pump while it is plugged in.
CAUTION This pump motor is equipped with an automatic resetting thermal protector and may restart unexpectedly.

Dimensions

Installation Piping & Basin
Piping must not be smaller than the pump discharge, in this case 2″. The pipe must be capable passing solids of at least 2″ in diameter. To meet minimum flow requirements, size the pipe as follows.
| A pipe size of | Will Handle a Flow Rate of |
| 2″ | 21 GPM |
| 2-1/2″ | 30 GPM |
| 3″ | 48 GPM |
- Before installation, check the pump and pipe inside the basin for damage that may have occurred during shipping.
- Dig a hole for the basin (if necessary). The hole should be approximately 24″ larger in diameter and 12″ deeper than the basin size to provide adequate room for the sub-base & backfill. Backfill and sub-base should be 1/8″ to 3/4″ pea gravel or crushed stone.
- Install the basin on top of the sub-base making sure the basin is level. If necessary, level the top of the basin level with the finished floor.
- Insert the 4″ inlet pipe through the inlet hub.
NOTE: To aid in installation, use liquid soap to lubricate the pipe and hub. Bevel or file the sharp edges of the pipe to prevent damage to the hub. Insert the pipe approximately 2″ into the basin and secure by tightening the stainless steel clamp. The pipe should pitch downward to the basin by approximately 1/4″ per foot to allow water to run into the basin. - Backfill around the basin with crushed stone or pea gravel.
A. 3/16″ Anti-airlock hole
B. Vent basin in accordance with applicable codes
C. Ball or gate valve (sold separate
D. Check valve / union combination (sold separately)
E. Liquid & gas tight seals
F. Electrical supply must be in accordance with the National Electric Code and/or other applicable codes.
- Install a 2″ vent pipe into the 2″ NPT threaded vent flange (B). Connect the vent pipe to the existing vent pipe or run the pipe through the roof of the building. The sewage basin MUST be vented in accordance with all local codes.
- Install a 2″ full flow check valve (C) (sold separately) onto the discharge pipe to prevent backflow into the basin. The check valve should be a full flow type and be capable of handling 2″ solids. Install the check valve with the flow direction arrow pointing in the direction of flow. For best performance, do not install the check valve more that 45° above the horizontal as solids may accumulate in the valve and prevent it from opening upon pump startup. It is recommended to use a union and check valve/ball valve combination to allow for easy removal of the pump. Install per the check valve manufacturer’s installation instructions.
- Connect the remaining discharge pipe from the check valve / ball valve to the septic tank, sewage line, etc., using the shortest length of pipe and fewest number of turns as possible.
Alarm
The use of an alarm (sold separately) is recommended to warn of a high-water condition resulting from pump and/or control malfunction. The power supply for the alarm should be on a separate circuit so that a circuit interruption to the pump will not affect the alarm circuit.
Operation
- Plug the piggy-back plug of the float switch into a 120 volt grounded outlet. See Figure 2
- The use of a GFCI is strongly recommended. Plug the pump plug into the back of the piggy-back float switch plug.
NOTE: If connecting the pump and float switch to a control panel, follow the manufacturers instructions for proper installation 2. Check the installation by filling the basin and observing the pump operation through several complete cycles. Make any necessary adjustments at this time.
Maintenance
DANGER Risk of electric shock. Always disconnect the power supply before attempting to install, service or perform maintenance on the pump.
WARNING All repairs must be made by an authorized service center.
CAUTION This submersible pump contains oil which may become pressurized and hot under normal operating conditions – allow the pump to cool for 2-3 hours before servicing.
- Periodically inspect and clean the anti-airlock hole.
- Inspect the float switch for any accumulated debris that may inhibit it from operating properly. Clean if necessary.
- The pump has sealed, permanently lubricated bearings and require no additional lubrication.
- In applications where the pump may not activate for extended periods of time, it is recommended to cycle the pump at least once per month to ensure the pumping system is working properly when needed.
Performances
Height and/or piping restriction will reduce the pump output performance. It is recommended to use the same size or larger pipe as the pump discharge for optimum performance.

| Low line voltage | Check wire size and increase if necessary | |
| Check valve is stuck in the closed position or defective | Inspect, repair or replace if necessary | |
| Check valve is installed backwards | Make sure valve is installed in the correct direction of flow | |
| Worn, damaged or clogged pump parts | Inspect for wear, damage or clog and clean or replace part if necessary | |
| Discharge head exceeds pump capacity | If pumping height is over 25′, the pump will not move water. See performance chart | |
| Pump does not shut off | Float switch is obstructed or stuck | Remove obstruction |
| Defective Float Switch | Replace float switch |
