As with many industries, the technology being used with new refrigeration systems continually evolves. Electronic controls are rapidly being used in many new designs, new refrigerants are being used, and motor technology is evolving. Manufacturers are increasingly designing their systems with unique controls and features that may apply only to their systems. Servicing, installing, and maintaining these new systems can be challenging. Sometimes they require us to reference material provided by the system or component manufacturer. Without this reference material, servicing, installing, or maintaining many of these new systems may be quite difficult or at times even impossible.

Just as equipment technology is evolving, so is the way manufacturers provide technical information. Most of the technical information provided by manufacturers today is in an electronic format, most commonly in a PDF file. This allows us to review this information using Adobe’s Acrobat reader, a free Internet download. This makes it very convenient and cost effective for everyone; you do not need to purchase multiple software programs to reference this information. Using an Adobe format offers another useful benefit — it has a very useful tool that allows you to search a word or phrase within a document. Adobe’s “Find” tool allows you to simply search where a word or phrase appears in the document. This can be very useful since it eliminates the need of having to read or scan through an entire document and directs you to the exact paragraph(s) of information that you need.

For example, suppose you are working on a low-temperature system using an electronic controller, and you need to find out how to change its defrost schedule. If you have never done this before, you will need to reference the controller’s manual to find out how. Instead of scanning through the entire manual, you can simply enter “defrost” into the “Find” toolbox and search for the sections of the manual where the word “defrost” appears. This will lead you to the section of the manual explaining how to modify the controller’s defrost schedule.
