This is the first in a series of free practice tests on handling refrigerants in low-pressure appliances and servicing low-pressure equipment. These practice tests are among the best mobile-friendly tests on the web and render great on phones and tablets for students and apprentices on the go. Please consider sharing our tests with others that may find them useful, individually or in forums. A typical setting for the high-pressure cut-out control on a recovery unit used for evacuating refrigerant from a low-pressure chiller is 10 psig. Correct answer is D: raising system pressure by heating with circulated hot water or heating blankets. A charged low pressure refrigeration system can be efficiently leak-checked by raising system pressure by heating with circulated hot water or heating blankets. The following safety precautions should be adhered to for low pressure systems:.

EPA Type 3 covers low-pressure appliances. Technicians working on a Type 3 appliance must be certified as either a Type 3 or a Universal technician. EPA Type 2 covers high-pressure refrigeration appliances. Commercial, industrial and large residential systems are included in it. Type 3 appliances are classified as low-pressure appliances. This is because the pressure inside these appliances is comparatively lower than the outside atmospheric pressure. Recall that the atmospheric pressure is the pressure surrounding us. Recall that the atmospheric pressure is The pressure inside a Type 3 appliance is anything below the atmospheric pressure of Pressure lower than the atmospheric pressure is called vacuum.

Before testing your knowledge of the different types of appliances, you need to pass the Core Section of your EPA exam. Available online in an open-book format, the Type I EPA certification enables you to service smaller appliances. This section includes proper recovery techniques and industry requirements for small appliances, including recovery in equipment made before and after November 15, Before you can service these smaller appliances, you must take the Core Section test. Although the test is open-book, if you want certifications beyond Type I, you must take the test in a proctored environment. This EPA certification enables you to service or dispose of medium to very-high-pressure appliances, except in applications such as small appliances or air conditioners within motor vehicles. The education and training focuses more on leak detection and properly testing equipment. Type II also focuses on recovery techniques and requirements to minimize loss or cross-contamination. The proper servicing and disposal of low-pressure appliances require Type III certification. This exam is different from Type II in that low-pressure systems work in a vacuum.
