"How to Repair Refrigerators and Freezers That Use R290 Refrigerant | True Commercial Refrigeration" Video Transcript
The goal of this video is to show you safely and correctly how to make a repair on any cabinet produced with R290 refrigerant. The first thing to consider is how do I identify the cabinet I'm working on uses R290 refrigerant. All R290 equipment is required to have special labeling throughout the cabinet. Besides the serial tag label, you will see several labels on the cabinet interior and the back of the cabinet. Additionally, the condensing unit will also have several labels on it. It is also required that all R290 equipment have red sleeves over the refrigerant line process tubes.
Now that you properly identified the camera as using R290 refrigerant, also be aware that the cabinet was manufactured to meet specificULl guidelines and standards that pertain to R290 refrigerant. Because of this, True requires any part used for the repair to be an OEM part. For any reason you receive a replacement part that is not exactly the same as the part you are replacing, stop and call true before continuing. All the fan motors have a sealed shaft. All the relay and temperature controls have sealed contacts. The wire connectors that we use require a certain amount of force to pull the wires out of the connectors, which eliminates any spark potential. Wire nuts and crimp type connectors do not meet this requirement -- therefore they should never be used in any R290 cabinet. For all refrigeration repairs, you're still required to follow good refrigeration practices.
Standard refrigeration tools will still be required -- including oxygen-free dry nitrogen, a micron gauge, and shut off file for your charging hose. In addition to these tools, you should also use as short of a refrigerant hoses as possible as well as a pinch off tool. Now let's focus on the additional specialized tools that will be required for R290 service. You will need a combustible gas leak detector, the safety placard. Use only R290 refrigerant. If you're using the 1 pound cylinder supplied by True, you will also need to use the specialized charging valve. These are the only specialized tools needed to service an R290 system. True offers these parts individually or as part of several types of R290 repair kits. Please contact True's parts department for pricing and availability. The following procedure should be followed when doing any type of refrigeration repair.
True requires the following good refrigeration practices. These practices should include but are not limited to: not leaving the refrigeration system open to the atmosphere for more than 15 minutes, always change the dryer whenever the refrigeration system has been opened, use a micron gauge and pull a vacuum to a minimum of 500 microns. The introduction to the refrigeration system of anything other than a flushing agent, nitrogen, R290, or refrigerant oil is prohibited. All refrigeration repairs should be made in a well-ventilated area. The repair we are going to show is replacing a condensing unit on an R290 system that was previously diagnosed with a locked up compressor...
