MR45 – Recovery Machine

Your Recovery Revolution.

Where to Buy

  • Smart, variable speed, one horsepower motor
  • Starts and runs easily even with low voltage
  • Minimizes liquid slugging and maximizes vapor recovery
  • Easy access ports
  • Water resistant to withstand direct rain
  • R32 Ready

The first. Still the best.

At Fieldpiece, we give you the tools you need to do your job right. That’s why the MR45 Digital Recovery Machine is the fastest, quietest, smoothest and lightest full-size recovery machine anywhere. It was the first to market in digital and it’s powered by a 1 horsepower DC motor and extra-large condenser, so you know it offers top-of-its class performance even on hot days. This super lightweight recovery machine even works in the rain.

Simple. Powerful. Smart.

Our onboard monitoring system adjusts motor performance, so it runs twice as fast on vapor vs. liquid. It also starts and runs easily on low voltage, so there’s no worry about power problems. The motor cranks up to 3000 rpm to achieve the fastest vapor recovery rate in UL testing. We also designed it with a single knob and simple purging feature along with easy access ports. With the MR45, you’ll have the easiest-to-use and lightest machine on the market and your recovery time on the job comes way down.

MR45 Features:

  • Protects from voltage drop (runs as low as 95 VAC)
  • Single dial self-purge
  • Twice the RPMs (3,000) and twice the horsepower (1HP) with DC Motor
  • Extra-large condenser cools faster, especially on hot days
  • Only 22 lbs.
  • Water resistant
  • Easy access ports
  • Long life and low friction with ceramic cylinders
  • Dual cylinder compressor
  • Easy hose connections and built-in power cord storage
  • Large backlit display with status messages
  • A2L ready including R32 

What’s Included:

  • (1) MR45 Recovery Machine

  • 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
