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:. Correct answer is B: the condenser or chiller barrel tubes are leaking. When there is excessive moisture collecting in the purge unit of a low pressure refrigeration system, this indicates that the condenser or chiller barrel tubes are leaking. When recharging a refrigeration system with R, what vapor pressure is necessary in the shells before charging with liquid? Correct answer is B: wait for at least a few minutes to see if the system pressure rises, indicating there is still refrigerant in liquid form or in the oil. After reaching the required recovery vacuum on a chiller, you should wait for at least a few minutes to see if the system pressure rises, indicating there is still refrigerant in liquid form or in the oil.

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
