608 Type I

When using a system-dependent recovery system on an appliance that has an operating compressor, the technician should;

Run the compressor and recover from the high side of the system only.

When using a system-dependent recovery system on an appliance that has a non-operating compressor, the technician should;

Place access fitting on both the low and high side of the system.

Self-contained or active recovery equipment;

Has its own means to recover refrigerant.

On a system with an operating compressor, recovery equipment must be capable of recovering;

90% refrigerant or achieving 4 inches of vacuum.

A small appliance is defined by EPA as;

Appliances manufactured, charged, and hermetically sealed in a factory that contain 5 lbs or less of refrigerant.

System-dependent or passive recovery equipment;

Captures refrigerant into a non-pressurized container.

With a non-operating system compressor, recovery equipment must be capable of recovering;

80 percent of the refrigerant or achieving 4 inches of vacuum.

If a strong odor is detected while performing a refrigerant recovery process,

A compressor burnout has likely occurred.

Recovering multiple types of refrigerants in the same cylinder;

will make the reclaimed refrigerants unreclaimable.

When filling a charging cylinder with a regulated refrigerant;

The refrigerant vapor that is vented off the top of the cylinder must be recovered.

When pressurizing a system with nitrogen you should;

charge through a pressure regulator and install a relief valve in the line downstream from the pressure regulator.

Which of the following is an example of a non-condensable?

Air

Which of the following is true regarding refrigerant leaks on small appliances?

EPA does not require repair, but leaks should be repaired whenever possible.

Type I Certification is required for;

persons handling refrigerant during maintenance, service, or repair of small appliances.

System-dependent recovery methods may only be used on appliances containing;

15 pounds of refrigerant or less.

When a system is in deep vacuum;

Never energize the compressor.

Technicians who perform sealed-system service on small appliances must have;

Type I or Universal certification.

Recovery equipment must be;

Certified by an EPA-approved testing laboratory.

Which HC refrigerant is allowed for use in NEW Domestic Small Appliances?

R-600a

Small appliances are equipped with a straight piece of tubing (process stub) that is used;

As the installation location for a piercing-type access valve.

If regulations change after the technician becomes certified;

The technician is responsible for complying with any changes to the regulations.

Small appliances in recreational vehicles may use refrigerants such as Ammonia, Hydrogen, and water. These refrigerants;

Should not be recovered

If, after installing a fitting for the purpose of recovering the appliance's refrigerant, you find that the system pressure is 0 psig;

Refrigerant recovery is not required.

After the refrigerant has been recovered, which of the following can be used to flush the system?

Nitrogen

Applying heat, with a heat gun, to the compressor

can help vaporize any trapped liquid refrigerant during recovery.
