Description

The MR45 is the first variable speed DC motor
machine with a digital display. Pump refrigerant
easier and quieter than ever before. Connect
your hoses without navigating around dark tight
spaces or picking the pump off the ground. View

to route refrigerant through MR45, and use the
self-purge function to pump the last traces into
the recovery cylinder instead of being left in the
machine or released into the environment.

First Aid for Refrigerant Exposure

Inhaled: Move to fresh air immediately.
Eye: Immediately flush eye with water. Seek medical attention.
Skin: Immediately flush skin with water. Seek medical attention.

General

1. This is not a consumer machine. Only qualified personnel trained

in the recovery or pumping of refrigerant may operate this
machine.
Read and understand this oper

2.

using MR45 to prevent injury or damage to you or equipment.

Environmental

1. Use only within operating conditions (32-122°F)

2. Ensure fan opening is clear of debris.

3. Explosion and fire risks:

Do not use near sewer lines.
Do not use in poorly ventilated enclosed areas.
Do not use near gasoline, acetylene, or other flammable gases.
Do not use to pump hydrocarbons.
Do not use near flames or sparks.
Assume all components are pressurized.

Personal Protection

1. Frostbite danger. Be careful using hoses.

2. Use personal protective equipment:

Wear safety goggles.
Wear earplugs if using for long durations.
Wear protective gloves.

MR45 Protection

1. Use only on approved list of refrigerants (page 9).

2. Do not use with hydrocarbons.

Setup

1. Repair any damaged parts before using.

2. Disconnect power and allow fan to stop before opening or
servicing MR45.

3. Perform self test periodically (page 22).

4. Ensure power cord is not damaged.

5. Ensure all equipment is grounded.

6. Extension cord options:
14 AWG or thicker, up to 50 feet (15 m)
12 AWG or thicker, up to 100 feet (30 m)

7. Ensure extension cord is grounded, 3 conductor grounded.

Operational

1. Use correct refrigerant hoses with ball valve shutoffs.

2. Keep track of the current amount of refrigerant in the cylinder.
Refrigerant scales are a good way to do this.

3. Overfilling a cylinder past 80% can cause an explosion and
violates DOT laws.

4. Close cylinder off from refrigerant if it reaches 80% of its capacity.

5. Use only DOT CFR 49 or UL-approved refrigerant cylinders for the
refrigerant being recovered.

6. Use recommended accessories.

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

8. Monitor pressures and temperatures.

9. Self purge MR45 after each use. No refrigerant should remain in
the machine.
