EPA Section 608 Type I_C

When installing any type of access fitting onto a sealed system the fitting should be __________ before proceeding with recovery.

• on the evaporator

• removed

• on the condenser

• leak tested

To ensure that all CFC, HCFC, or HFC refrigerant has been removed from a frost-free refrigerator, the __________ can be energized to increase the refrigerant's temperature and vaporize any liquid.

• condenser fan motor

• evaporator fan motor

• defrost heater

• compressor

Because __________ tend to leak over time, they should not remain on the refrigeration systems after completion of the repair.

• A. schrader valves

• B. solderless type piercing valves

• C. service valves

• D. all answers are correct

An appliance with an operating compressor and completely restricted capillary tube or metering device requires __________.

• only one access valve on the low side of the system

• only one access valve on the high side of the system

• two access valves on the system

• two access valves on the high side of the system

A __________ recovery process for small appliances can capture refrigerant in a non-pressurized container.

• passive, self-contained

• active, system-dependent

• passive, system-dependent

• active, self-contained

If the pressure in an appliance is at __________ after installing and opening a piercing access valve, the recovery procedure cannot begin.

• 0 psig

• 100 psig

• 10" Hg.

• 4" Hg.

When using the __________ recovery process and the compressor does not run, both the high and low side of the system must be accessed for refrigerant recovery.

• system-dependent (passive)

• system-dependent (active)

• self-contained (passive)

• self-contained (active)

The approximate pressure of an R-134a cylinder that does not contain any non-condensable impurities and is stored in a room at 80°F is equal to a pressure of __________.

• 57 psig.

• 77 psig.

• 87 psig.

• 67 psig.

__________ should be installed when recovering refrigerant from a household refrigerator or any other appliance to improve the speed of active recovery.

• A. A low side access valve

• B. A low side access valve

• C. Both low and high-side access valves

• D. A piercing valve

When using a self-contained (active) recovery device and there is a large volume of non-condensable gas in the refrigerant being recovered, excessive pressure can occur on __________ of the recovery machine and in the recovery cylinder.

• the suction side

• the high side

• the low side

• on both high and low sides
