What qualifies as a small appliance under Section 608 Type I?
Small appliances include factory-charged, hermetically sealed appliances containing five pounds or less of refrigerant, such as household refrigerators and window air conditioners.
Which Section 608 requirements govern small-appliance servicing?
Section 608 Type I requirements govern servicing small appliances containing five pounds or less of refrigerant.
How does self-contained recovery equipment move refrigerant?
Self-contained equipment uses its own compressor or another means to draw refrigerant from an appliance and move it into an external recovery container.
What limits apply to system-dependent recovery equipment?
It relies on the appliance compressor or internal pressure. It may not be used with an appliance containing more than 15 pounds of refrigerant unless permanently attached as a pump-out unit.
How should recovery equipment be selected for a small appliance?
Use recovery equipment approved for the appliance and refrigerant being handled, and follow the equipment manufacturer’s instructions.
What recovery percentage applies to equipment made before November 15, 1993?
With recovery equipment manufactured before November 15, 1993, recover at least 80% of the refrigerant.
What is the recovery target for post-November 14, 1993 equipment with an operational compressor?
Recover at least 90% of the refrigerant when the compressor is operational.
What is the recovery target for post-November 14, 1993 equipment with a failed compressor?
Recover at least 80% of the refrigerant when the compressor is not operational.
What vacuum endpoint is an alternative to the percentage recovery targets?
Evacuate the appliance to 4 inches of mercury vacuum. This is an alternative compliance method.
Do recovery percentages indicate refrigerant pressure?
The percentages describe the amount of refrigerant recovered from the appliance; they are not pressure readings.
When may a technician open a small appliance’s sealed system?
Verify the required recovery percentage or the 4-inch-mercury-vacuum endpoint using the prescribed method before opening the sealed system.
How do recovery, recycling, and reclamation differ?
Recovery removes refrigerant and stores it in a container; it does not clean it. Recycling cleans refrigerant for reuse, while reclamation processes it to applicable purity specifications.
