MR45 – Digital Refrigerant Recovery Machine

Your Recovery Revolution.

Where to Buy

Wide operating voltage (95 to 130 VAC)
Minimizes liquid slugging and maximizes vapor recovery
Easy access ports
Lightweight
A2L Compatible
3 selectable auto-stop levels

Welcome to the Recovery Revolution

The MR45 is the first recovery machine with a smart variable speed DC motor that accelerates during vapor recovery. It has an oversize compressor that allows you to pump refrigerant more easily and quietly than ever before. Connect your hoses without lifting the pump off the ground. View status messages and pressures directly on the large backlit display.

Its lightweight size allows you to easily transport the machine to and from the job site. Turn the single rubberized control valve to route refrigerant through the MR45, and use the self-purge function to pump the last traces of refrigerant into the recovery cylinder instead of leaving it in the machine or releasing it into the environment. Class A2L compatibility for a wide range of jobs. To avoid contaminating recovered refrigerant, MR45 automatically stops at 0 psig/bar by default.

  • Adjusts for voltage drop (runs as low as 95 VAC)
  • Single dial self-purge
  • Super fast DC motor (1 HP @3000 RPM)
  • Extra large condenser cools faster, especially on hot days
  • Only 22 lbs
  • Rubberized housing protects components
  • Easy access ports and built in power cord storage
  • Twin cylinder compressor
  • Ceramic cylinders resist abrasion
  • Large backlit display with status messages
  • Class A2L compatibility for a wide range of jobs
  • 3 selectable auto-stop levels

  • Why won't the motor start?

      1. High Voltage Warning Motor stopped. Voltage was above 130 VAC.
      2. Low Voltage Warning Motor stopped. Voltage was below 95 VAC.
      3. Motor Fault 1 Motor stopped. Motor temp. measured above operating range.
      4. Motor Fault 2 (“throttle” shows on display) Motor stopped. Motor current (amps) rose above operating range. Throttle RECOVERY to reduce cylinder pressure (page 19).
  • What does E01/E02 mean?

    • Pressure sensor either unplugged or no longer working.

  • What does throttle mean?

      1. Input and Output partially open.
      2. Rotate away from RECOVER in either direction to reduce liquid slugging if knocking occurs. This slows the flow of refrigerant so the machine operates more smoothly.
      3. Only throttle as much as needed for smooth operation.
  • Are there replacement parts?

    • Yes.  Contact Fieldpiece at 714-634-1844 for availability.

  • Warranty?

    • Yes, the MR45 comes with a one year warranty from date of purchase. If date of purchase is unavailable, serial number will be used. Serial number is located on the bottom plate of MR45.

  • Maintenance?

      1. Wipe with damp cloth to clean the exterior. Do not use solvents. To extend the life of internal seals, occasionally pump a teaspoon of mineral oil through MR45.
      2. When the mesh screen filter becomes dirty and clogged, it means it’s working to keep your MR45 working well for a long time. You need to clean or replace this screen often. Visit our website for information on obtaining extra mesh screens.
  • Do I need to use a filter dryer?

    • Use a filter drier on the input port and change it often to protect machine from contaminated refrigerants.

  • Can I use propane?

    • No, the MR45 is not UL certified for A3 refrigerants, therefore it cannot be used with any combustible refrigerants.

  • Is there a fuse to change?

    • Yes, there is a fuse located at the bottom of the MR45 inside the bottom PCB board. We have teardown instructions to help break the MR45 down to get to the fuse.

  • What is the high cut-out set to?

    • The High cut out is set to approx. 550 PSI

  • Is the MR45 A2L Compatible?

    • Yes. For use only by qualified and certified technicians in the safe use, handling, and transporting of refrigerants.  Please refer to flammable refrigerant safety guides, regional codes and legislation for more information.
