1. Introduction
The Honeywell Braukmann Sparco AM101-US-1 Thermostatic Mixing Valve is designed to precisely adjust, maintain, and limit hot water temperature to a user-defined setting. This valve enhances safety and can contribute to energy savings in various applications.
It is suitable for both domestic and commercial installations, including hot water systems (tankless heaters or storage tanks), showers, sinks, baths, washing machines, solar, and heat pump systems. Its accuracy and energy-saving capabilities make it ideal for environments requiring precise temperature control.
Key Features:
- Constant water temperature under varying operating conditions.
- Maintains constant temperature in systems with recirculation.
- Proportional valve for simultaneous control of hot and cold water.
- Enables energy savings through lower supply temperatures.
- Provides control of hot water up to shutoff.
2. Safety Information
Please read all instructions carefully before installation and operation. Failure to follow these instructions could result in property damage, personal injury, or death.
- Professional Installation: Installation should be performed by a qualified plumber or technician in accordance with local codes and regulations.
- Hot Water Hazard: This device handles hot water. Exercise extreme caution to prevent scalding. Always test water temperature before use, especially in households with children or elderly individuals.
- Pressure Relief: Ensure the water supply is turned off and system pressure is relieved before attempting any installation or maintenance.
- Material Compatibility: Use only compatible materials and sealants as recommended by plumbing standards.
- Water Quality: Be aware that water conditions (e.g., hard water, mineral content) can affect valve performance and longevity.

5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your thermostatic mixing valve. Refer to local plumbing codes and consult a professional if you are unsure about any steps.
5.1 Pre-Installation Checklist:
- Ensure the main water supply is turned off.
- Drain the hot and cold water lines to relieve pressure.
- Gather all necessary tools and additional plumbing components.
- Inspect the valve for any visible damage.
5.2 Installation Steps:
- Prepare Connections: The valve features 3/4" Union-Sweat connections. If sweating copper connections, ensure the connectors are properly prepared. You may sweat the connectors onto the copper tubing first, then allow them to cool before installing the valve and seals to prevent heat damage.
- Connect Valve: Carefully connect the valve to the hot and cold water lines. Ensure the flow direction arrows on the valve body match the water flow. When tightening nuts, support the pipes to prevent damage, as connections can be tight.
- Seal Gaskets: If reusing nuts from an old unit, ensure you remove any old paper-style gaskets and thoroughly clean the flanges with an abrasive pad (e.g., Scotchbrite or the green side of a sponge) before installing new seals.
- Secure Valve: Secure the valve firmly in place.
- Restore Water Supply: Slowly turn on the main water supply and check for leaks.

6. Operating Instructions
6.1 Temperature Adjustment:
The AM101-US-1 valve allows for temperature adjustment within a range of 100-145°F (38-63°C). To adjust the mixed water temperature:
- Locate the adjustment knob on the valve.
- To Adjust: Loosen the screw on the adjustment knob. Then, gently pull the plastic knob upwards to disengage it from its locked position.
- Rotate the knob to increase or decrease the desired temperature. Turning the knob clockwise typically decreases the temperature, while counter-clockwise increases it.
- Once the desired temperature is set, push the knob back down to lock it in place and tighten the screw.
- Always test the water temperature with a thermometer to ensure it is at a safe and desired level, especially if children or elderly individuals will be using the water.
Note: The adjustment knob may be stiff initially. If it is very difficult to turn, ensure it is properly disengaged by pulling it out after loosening the screw.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your thermostatic mixing valve.
- Annual Inspection: It is recommended to inspect the valve annually for any signs of leaks, corrosion, or mineral buildup.
- Water Quality Impact: In areas with hard water or high mineral content (e.g., well water), internal mineral buildup can occur, potentially causing the valve to stick or temper water inconsistently. Depending on water conditions, the valve may require more frequent inspection or replacement (e.g., every 1-2 years).
- Cleaning: If mineral buildup is suspected, the valve may need to be disassembled and cleaned by a qualified professional. Always turn off the water supply and relieve pressure before attempting any internal cleaning.
- Temperature Verification: Periodically verify the mixed water temperature with a thermometer to ensure the valve is maintaining the desired setting.
