Product Overview
The Zoeller 3098-0001 M3098 is a robust 1/2 HP automatic high-temperature submersible pump designed for residential and commercial wastewater dewatering applications. This pump series features electrical components engineered to meet National Electrical Code requirements for service up to 200°F (93°C). Its automatic operation is managed by a float-operated mechanical switch box, ensuring reliable performance in demanding environments.

This image displays the Zoeller 3098-0001 M3098 submersible pump. The pump unit, colored green, is positioned at the bottom, connected to a vertical discharge pipe. A mechanical float switch assembly, featuring two white floats, is attached to the pipe, designed to activate the pump automatically based on water levels. Electrical conduit and wiring are visible, connecting the pump to the control box mounted higher on the pipe.
Key Features:
- Designed for high-temperature dewatering applications up to 200°F (93°C).
- Equipped with a 3-foot conduit length for flexible installation.
- All control components in contact with water are high-temperature rated for durability.
- Features a float-operated mechanical switch box, mounted on the discharge pipe above the operating level, for automatic control.
- Mechanical seal includes a NI-Resist rotary face and Viton elastomer for enhanced longevity.
Important Safety Information
Read and understand all instructions before installing, operating, or performing maintenance on this pump. Failure to follow these instructions could result in serious injury or property damage.
- Electrical Hazard: This pump operates on 115 Volts. Always disconnect power before servicing or installing the pump. Ensure all electrical connections comply with local codes and the National Electrical Code (NEC).
- High Temperature Warning: This pump is designed for high-temperature service. The pumped liquid can be extremely hot (up to 200°F / 93°C). Exercise extreme caution to prevent burns.
- Check Valve Requirement: For high-temperature service, any check valves used in the system MUST be all-metal swing-type check valves. Plastic or rubber components may degrade under high heat.
- Basin Material: The basin or pit material where the pump is installed must be capable of withstanding the sustained, elevated temperatures anticipated. Ensure the basin material is heat-resistant.
- Proper Grounding: Ensure the pump is properly grounded to prevent electrical shock.
- Qualified Personnel: Installation and service should only be performed by qualified personnel.
Installation Guide
Pre-Installation Checklist:
- Verify that the power supply is 115 Volts AC.
- Ensure the basin or pit is clean and free of debris.
- Confirm that the basin material can withstand temperatures up to 200°F (93°C).
- Have all necessary plumbing fittings, including an all-metal swing-type check valve if required.
- Ensure adequate ventilation in the installation area.
Installation Steps:
- Position the Pump: Place the pump on a solid, level surface at the bottom of the basin. Ensure it is stable and will not tip over.
- Connect Discharge Piping: Connect the discharge piping to the pump outlet. Use appropriate high-temperature rated piping materials.
- Install Check Valve: If a check valve is required to prevent backflow, install an all-metal swing-type check valve in the discharge line above the pump.
- Mount Float Switch: Securely mount the float-operated mechanical switch box to the discharge pipe above the anticipated operating water level. Ensure the floats have free movement and will not interfere with the basin walls or other components.
- Electrical Connection: Connect the pump's power cord to a dedicated 115V grounded electrical outlet. Ensure the circuit is protected by a ground fault circuit interrupter (GFCI) if required by local codes. All wiring must be done by a qualified electrician and comply with all applicable electrical codes.
- Test Operation: Once installed, fill the basin with water to test the pump's automatic operation. Observe that the pump turns on when the water level rises to activate the float switch and turns off when the water level drops.
Operating Instructions
The Zoeller 3098-0001 M3098 pump is designed for automatic operation. Once properly installed and connected to power, the pump will activate and deactivate based on the water level in the basin, as controlled by the float switch.
- Automatic Operation: The pump will automatically turn on when the water level rises to the 'on' point of the float switch and will continue to pump until the water level drops to the 'off' point.
- Continuous Monitoring: Periodically check the pump's operation to ensure it is cycling correctly and effectively dewatering the area.
- Avoid Dry Running: Do not allow the pump to run dry for extended periods, as this can cause damage to the motor and seals. The float switch is designed to prevent this under normal operating conditions.
Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your Zoeller pump. Always disconnect power before performing any maintenance.
- Inspect Basin: Periodically inspect the basin for excessive sludge, debris, or foreign objects that could impede pump operation or float switch movement. Clean as necessary.
- Check Float Switch: Ensure the float switch moves freely and is not obstructed by debris or the basin walls.
- Inspect Power Cord: Check the power cord for any signs of damage, fraying, or insulation degradation. Replace if damaged.
- Pump Housing: Inspect the pump housing for any cracks or damage.
- Discharge Piping: Verify that the discharge piping is clear and free of blockages.
Troubleshooting
This section provides solutions to common issues you might encounter with your pump. For problems not listed here, contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not turn on. | No power to pump. Float switch obstructed or faulty. Motor overload. | Check power supply, circuit breaker, and GFCI. Clear any obstructions around the float switch; test switch operation. Allow motor to cool; check for blockages in pump impeller. |
| Pump runs continuously. | Float switch stuck in 'on' position. Check valve faulty or missing. Pump undersized for inflow. | Clear obstructions around float switch; ensure free movement. Inspect or install an all-metal swing-type check valve. Consult a professional to assess pump capacity. |
| Pump runs but no water is discharged. | Discharge pipe blocked. Impeller clogged or damaged. Air lock. | Check and clear discharge piping. Disconnect power, inspect and clear impeller. Ensure pump is fully submerged and free of air pockets. |
| Pump cycles too frequently. | Basin too small. Check valve leaking. Float switch setting too narrow. | Consider a larger basin or consult a professional. Inspect or replace check valve. Adjust float switch settings if possible, or ensure proper float travel. |
