Summary of Contents for Leonard PNV-200-LF

  • Page 1 INSTALLATION AND FIELD ADJUSTMENTS ARE THE RESPONSIBILITY OF INSTALLER. READ ALL INSTRUCTIONS PRIOR TO INSTALLATION 1. Leonard Proton Valves are factory pre-assembled and 4. Flush pipes thoroughly after system has been tested and include digital mixing valve and controls connected.
  • Page 2 WARNING The Leonard Proton Digital Mixing Valve is an electronically controlled device utilizing DC circuitry. The connection of the Electronic Control Box to the Mechanical Valve Components is very simple. There is a 3-wire RTD Temperature Probe as well as a 4-wire Motor Harness that must be connected and plugged into the box on the left and middle (respectively) connection points on the bottom of the Control Box.
  • Page 3 PROTON 1.0 – INSTALLATION INSTRUCTIONS 1. The Proton Unit MUST be piped according to Leonard Required Piping Method W (see page 25). 2. Mount valve body, outlet facing down, and plumb inlet and outlet connections. DO NOT introduce water to the valve until completion of these instructions.
  • Page 4 PROTON 1.0 - DEGREES “F” OR “C” Protons can display in either degrees “F” Fahrenheit or degrees “C” Celsius. The units come standard as degrees “F” Fahrenheit. To change the units to degrees “C” Celsius it is as simple as removing a “jumper” on the board on the back on the control box as seen in the pictures below.
  • Page 5 Proton 1.0 – User Screens Home Screen: Current outlet temperature and Set point temperature Home Screen: After initial “Full Sweep” the bottom line of the digital display indicates the measured sweep value of the valve, hot to cold. Please record this numerical value as you will need it for calibration Screen 2 below.
