Installation Overview
The installation of the LTP-1 should be performed by a qualified technician or a licensed plumber to ensure compliance with local plumbing codes and manufacturer guidelines. Below is a step-by-step installation overview based on the information provided in the manufacturer’s documentation.
1. Site Preparation
Before beginning installation, ensure that the site is prepared according to the following criteria:
- The pump must be installed in a location where the reservoir can be placed under the sink or appliance without obstructing access to the fixtures.
- The installation area should be dry and free of standing water to prevent damage to the pump or electrical components.
- Confirm that the plumbing system allows for the pump to be installed without the need to break concrete or reconfigure existing drain lines.
The LTP-1 is designed to be installed under utility sinks and is compatible with standard plumbing configurations. Its unitized construction and structural foam polypropylene housing make it durable and easy to handle during installation.
2. Electrical Connections
The LTP-1 requires a dedicated 115V electrical supply with a 5.0A capacity. The pump is equipped with an 8-foot cord and a standard plug, which should be connected to a properly grounded outlet. It is important to verify that the outlet is located within a safe distance from the pump and not exposed to moisture.
- Ensure that the electrical connection is made in accordance with local electrical codes.
- A sealed switch assembly is included to protect against moisture and ensure long-term reliability.
- Avoid using extension cords or multi-outlet strips, as these can compromise the performance and safety of the pump.
3. Plumbing Connections
The LTP-1 features a 1-1/2" FNPT inlet and a 1" FNPT discharge port. These ports should be connected to the existing plumbing system using standard pipe fittings. It is important to ensure that all connections are secure and leak-free to prevent water damage and ensure efficient operation.
- Connect the inlet port to the source of wastewater (e.g., sink drain, laundry machine).
- Connect the discharge port to the main drain line or a designated disposal point.
- Use appropriate sealing materials (e.g., pipe thread sealant or Teflon tape) to prevent leaks at all threaded connections.
The pump does not require a main stack vent connection, which simplifies installation and reduces the need for additional plumbing modifications.
4. Mounting the Reservoir
The LTP-1 is equipped with a sealed reservoir that holds up to 2 gallons of water. This reservoir should be placed under the sink or appliance to collect wastewater before it is pumped out. The reservoir is designed to fit under standard utility sinks and is constructed from durable polypropylene to resist corrosion and chemical exposure.
- Position the reservoir so that it is level and does not interfere with the movement of the sink or appliance.
- Ensure that the reservoir is securely mounted to prevent tipping or shifting during operation.
- The suds-proof design of the reservoir ensures that it can handle typical cleaning agents and detergents used in laundry and utility applications.
5. Final Checks and Testing
Once the pump and plumbing are installed, perform the following checks to ensure proper operation:
- Verify that all electrical and plumbing connections are secure and leak-free.
- Confirm that the pump is positioned correctly and that the reservoir is functioning as intended.
- Test the pump by filling the reservoir with water and observing the pump’s operation. It should activate when the water level reaches the switch and shut off once the water is pumped out.
After confirming that the pump operates correctly, monitor its performance over the first few days to ensure that it is handling the expected volume of water and that there are no signs of leaks, noise, or electrical issues.
Maintenance and Troubleshooting
The Hartell LTP-1 is designed for long-term reliability, but regular maintenance and periodic inspections can help extend its lifespan and ensure continued performance.
Routine Maintenance
- Clean the Reservoir: Over time, debris and sediment may accumulate in the reservoir. Periodically clean the reservoir with a mild detergent and water to prevent clogging and reduce the risk of pump damage.
- Inspect Plumbing Connections: Check all inlet and discharge connections for signs of leaks or wear. Tighten fittings as needed and replace any damaged components.
- Test Electrical Components: Ensure that the power cord, switch, and outlet are functioning properly. Replace any damaged or worn electrical components immediately.
Common Issues and Solutions
- Pump Not Activating: If the pump does not turn on when the reservoir is filled, check the electrical connections, switch assembly, and water level sensor. Ensure that the pump is receiving power and that the water level is above the switch.
- Low Flow or Pressure: If the pump is not moving water at the expected rate, check for blockages in the inlet or discharge lines. Clean the pump and plumbing as needed.
- Noise or Vibration: Excessive noise or vibration may indicate that the pump is not level or that the reservoir is not properly mounted. Adjust the pump and reservoir as needed to eliminate the issue.
Compliance and Safety
The Hartell LTP-1 is designed to comply with industry standards and local plumbing codes. However, it is the responsibility of the installer and user to ensure that the pump is installed and operated in accordance with all applicable regulations.
- Local Codes: Always consult local plumbing and electrical codes before installation. The pump must be installed in a manner that is consistent with these requirements.
- NSPC Section 11.7.9: The LTP-1 complies with the requirements outlined in NSPC section 11.7.9, which governs the installation of utility sink drain pumps. Confirm that local codes align with these standards before proceeding.
- Electrical Safety: The pump must be installed on a dedicated circuit and connected to a properly grounded outlet. Avoid using extension cords or multi-outlet strips to prevent electrical hazards.
Conclusion
The Hartell LTP-1 is a versatile and reliable utility sink drain pump that is well-suited for residential and light commercial applications. Its 2-gallon reservoir, sealed construction, and high flow rates make it an effective solution for managing wastewater in areas where fixtures are installed below the main drain line. When installed correctly and maintained regularly, the LTP-1 provides efficient, long-term performance and helps eliminate the need for complex plumbing modifications.
By following the manufacturer’s installation guidelines and adhering to local codes, users can ensure that the LTP-1 functions safely and effectively for years to come. As with any electrical and plumbing equipment, it is important to involve qualified professionals during installation to minimize risks and ensure compliance with all relevant regulations.
