AccuMix II

UPC 407.3 compliant handwashing.

AccuMix II™ tankless electric water heater is designed for handwashing solutions in public-use lavatories. All AccuMix II models feature an integrated ASSE 1070 mixing valve and are factory set not to exceed 105 °F for safe handwashing. The units are mountable in any orientation for a simplified, flexible installation. Silent operation is available on all models except for AM012240T. Mount the unit within two feet of the fixture for best performance.


Integrated ASSE 1070 mixing valve

The integrated mixing valve meets ASSE 1070 and the unit meets UPC 407.3 requirements when properly installed. Keep the installation small with a single input line and a compact unit with mixing valve included.

Mount in any orientation for a flexible installation

AccuMix II mounts in any horizontal or vertical orientation and is an ideal solution for environments with space restrictions or pre-existing plumbing connections. Install under a counter, on a wall, or wherever is the most convenient spot for any application.

Compact size saves space

Keep the installation footprint down with an AccuMix II unit. All tankless electric water heaters are compact, but the AccuMix II family eliminates additional plumbing needs with the integrated ASSE 1070 mixing valve. Simplify the installation process with AccuMix II.

Thermostatic control for temperature stability.

The water is heated by the heating element while the water temperature and flow rate are monitored by the control board. The self-modulating software compares the actual outlet temperature to the desired temperature and makes adjustments to the power applied if required.

Digital LED display

The digital display communicates system status and heater operation feedback to ease troubleshooting. For additional information on functionality, view the AccuMix II user manual.


How It Works

Step 1
Inlet fitting

Water enters the heater through the 3/8″ compression fitting.

Step 2
Inlet temperature thermistor and flow sensor.

The inlet temperature and gallons-per-minute flow rate are measured and the data is sent to the control board.

Step 3
Control board with digital display.

The software calculates the amount of power to be applied to the heating element based on the inlet temperature, flow rate, and set temperature.

System status and operation feedback are communicated via the display.

Step 4
Triac assembly.

Triacs modulate the power to the heating elements to achieve the correct output.

Step 5
Heating element.

The heating elements activate and heat the outgoing water to the set temperature.

Step 6
Outlet temperature thermistor.

Outlet thermistor sends the hot water temperature to the control board. Self-modulating software compares the actual outlet temperature to the desired temperature and makes adjustments if required.

Step 7
ASSE 1070 mixing valve.

ASSE 1070 rated mixing valve ensures the outlet temperature is always within code requirements.
