When does servicing a small appliance generally require Section 608 certification?

A technician who services a small appliance and may open its refrigerant circuit generally needs Section 608 certification.

What certification exception applies to small-appliance disposal?

There is a federal certification exception for people recovering refrigerant from small appliances in the waste stream as part of disposal. Recovery and safe-disposal rules still apply.

When must refrigerant be recovered from a small appliance?

Recover refrigerant before opening the refrigerant circuit or disposing of the appliance.

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

For equipment manufactured before November 15, 1993, the percentage method requires 80% recovery, regardless of compressor condition.

What percentage applies to newer equipment with a functioning compressor?

For equipment manufactured on or after November 15, 1993, a functioning compressor requires 90% recovery under the percentage method.

What percentage applies to newer equipment with an inoperative compressor?

For equipment manufactured on or after November 15, 1993, an inoperative compressor requires 80% recovery under the percentage method.

What evacuation level is an alternative to percentage recovery?

As an alternative to the applicable percentage-recovery method, evacuate the appliance to 4 inches of mercury vacuum.

How does self-contained recovery equipment move refrigerant?

Self-contained, or active, equipment has its own means of moving refrigerant into a recovery container.

What charge limit applies to system-dependent recovery equipment?

System-dependent, or passive, equipment relies on the appliance compressor or system pressure. It is generally limited to appliances with a full charge of 15 pounds or less, unless permanently attached as a pump-out unit.

With passive recovery and an inoperative compressor, which sides need access?

Provide access to both the high and low sides so refrigerant trapped on either side can be recovered.
