Q&A
Q: What is the Taco HLS-2 Hot-Link Recirculation System?
A: The Taco HLS-2 is a high-efficiency, 115V circulator pump designed for domestic hot water recirculation. It ensures instant hot water at fixtures by circulating cooled water back to the water heater through the cold line, eliminating the need for dedicated return piping.
Q: What are the key specifications of the HLS-2?
A: The HLS-2 features a 1/40 HP motor operating at 115V, 60 Hz, with a maximum amperage of 0.52A. It has a maximum fluid temperature of 220°F (104°C) and a maximum operating pressure of 125 PSI. The system includes the circulator, Hot-Link bypass valve, adapter unions, and flex hoses.
Q: How does the HLS-2 conserve water?
A: By circulating cooled water back to the water heater, the HLS-2 reduces the time it takes to get hot water to fixtures, saving up to 12,000 gallons of water per year.
Q: Is the HLS-2 easy to install?
A: Yes, the HLS-2 is designed for easy retrofit installations using existing plumbing. The Hot-Link valve's unique thermal disk technology allows for a return loop through the cold line, and the clean-in-place design simplifies maintenance.
Q: What applications is the HLS-2 suitable for?
A: The HLS-2 is ideal for domestic hot water recirculation systems in residential applications with tank-type water heaters.
Maintenance Tips
-
Regular Operation Checks:
-
Ensure the system operates smoothly, with the pump running quietly and without any unusual noise or vibration.
-
Verify that the recirculation system maintains the desired water temperature and pressure.
-
Visual Inspections:
-
Inspect the pump and plumbing for any visible leaks or signs of wear.
-
Check for any corrosion or damage to the components, especially the pump housing and pipes.
-
Electrical Connections:
-
Ensure all electrical connections are secure, free from corrosion, and properly connected.
-
Double-check that the voltage and amperage supplied match the system’s specifications.
-
System Pressure Monitoring:
-
Regularly monitor the system's water pressure to ensure it’s within the recommended range.
-
Adjust the pressure as needed to maintain optimal performance and prevent strain on the pump.
-
Flow Rate Verification:
-
Ensure the flow rate aligns with the system’s specifications for efficient hot water circulation.
-
Adjust or clean the system if flow issues arise.
