What is the effect of pressurizing a system without following proper procedures?

Pressurizing a refrigeration system without adhering to the correct procedures can lead to significant risks, particularly the potential for system damage. Proper procedures are designed to ensure the integrity of the system and the safety of the technician. When a system is improperly pressurized, it can create excess pressure that may exceed the design limits of components such as compressors, condensers, and expansion valves. This excess pressure can result in mechanical failures, leaks, or ruptures, causing not only costly repairs but also creating safety hazards.

When dealing with refrigerants and pressurization, maintaining the balance of the system is critical. Failure to do so can lead to incorrect pressures that affect the operation of the system, ultimately resulting in degraded performance or complete system failure. Therefore, the emphasis on following proper procedures during pressurization is paramount to ensure both the longevity of the equipment and the safety of personnel working on or around the system.
