Which appliances fall under Type II certification?
It covers service or disposal of medium-, high-, and very-high-pressure appliances, except small appliances, motor-vehicle air conditioners, and MVAC-like appliances.
Does connecting gauges to an appliance generally require Section 608 certification?
Yes. Connecting gauges or hoses can compromise the refrigerant circuit, so Section 608 certification is generally required.
Does a pressure check alone count as a leak inspection?
No. It may indicate a leak, but a leak inspection must locate the leak, using methods such as a leak detector or bubble test.
What are the Section 608 leak-repair applicability threshold and trigger rates?
They generally apply to appliances with at least 50 pounds of ozone-depleting refrigerant when the annual leak rate exceeds the applicable trigger: 30% for industrial process refrigeration, 20% for commercial refrigeration, and 10% for comfort cooling and other appliances.
What must an owner or operator generally do about a qualifying leak?
Owners or operators generally must repair qualifying leaks within 30 days or develop a retrofit or retirement plan within that period; exceptions and extensions may apply.
What equipment and handling rules apply to refrigerant recovery?
Do not intentionally vent refrigerant. Recovery or recycling equipment must be appropriate and operated according to its instructions; except for equipment made before November 15, 1993, it must be certified by an EPA-approved testing organization.
Why recover liquid refrigerant first when feasible?
When the equipment and procedure allow, recovering liquid first can make the recovery process faster.
What can a pressure rise after evacuation indicate?
After the required evacuation level is reached, let pressure stabilize and check for a rise. Rising pressure can indicate refrigerant remains in the system or oil.
When must recovered refrigerant be reclaimed before transfer for reuse?
It may generally be returned to the same appliance or another appliance owned by the same person. Before transfer to a different owner for reuse, it must be reclaimed by an EPA-certified reclaimer.
What evacuation level applies to a high-pressure appliance charged with under 200 pounds?
For a high-pressure appliance with a full charge under 200 pounds, the required level is 0 inches of mercury vacuum, regardless of whether the recovery equipment was made before or after November 15, 1993.
Does 0 inches of mercury vacuum mean a system may be opened while positively pressurized?
It means the table requires no vacuum below atmospheric pressure; it does not permit opening a system that is still positively pressurized.
What pressure limit applies to leaking components under the limited leak-related evacuation exception?
Isolate components where possible, evacuate non-leaking portions to the specified level, and evacuate leaking portions to the lowest achievable level without substantial refrigerant contamination—but not above 0 psig.
