6 Type I Certification Practice Free Online FlashCards

What work does Type I certification cover?

Type I certification covers technicians who maintain, service, or repair small appliances under EPA Section 608.

What makes an appliance a small appliance under Section 608?

It must be fully manufactured, charged, and hermetically sealed in a factory, and contain five pounds or less of refrigerant.

Does exactly five pounds of refrigerant meet the charge limit?

Yes. The charge limit includes exactly five pounds, as long as the appliance also meets the factory-manufacture, charging, and sealing requirements.

Name examples of small appliances.

Household refrigerators and freezers, window and portable air conditioners, dehumidifiers, vending machines, and drinking-water coolers are examples.

When must refrigerant be recovered from a small appliance?

Recover refrigerant with appropriate recovery equipment before opening a small appliance for service or disposing of it.

What recovery percentage applies to equipment made before November 15, 1993?

Equipment manufactured before November 15, 1993, requires 80% recovery, regardless of compressor condition.

What recovery percentage applies to newer equipment with a functional compressor?

Equipment made on or after November 15, 1993, requires 90% recovery when the compressor functions.

What recovery percentage applies to newer equipment with a failed compressor?

Equipment made on or after November 15, 1993, requires 80% recovery when the compressor is not functional.

What vacuum level is an alternative to the recovery percentage?

Instead of meeting the applicable recovery percentage, evacuate the appliance to 4 inches of mercury vacuum.

How should a functional compressor be used with a passive recovery device?

Operate the functional appliance compressor during recovery, following the passive device manufacturer’s instructions.

Why does passive recovery from a failed-compressor appliance need access to both sides?

A passive device cannot rely on a failed compressor to circulate refrigerant, so provide access to both the high and low sides.

Where should access valves be installed when the compressor is inoperative?

Install access valves on both the high side and the low side of the appliance circuit.
