ANSWER: Type I or Universal certification.
A small appliance is defined by EPA as; - ANSWER: Appliances manufactured,
charged, and hermetically sealed in a factory with 5 Lbs or less of refrigerant
Type I Certification is required for; - ANSWER: persons handling refrigerant during
maintenance, service, or repair of small appliances
If regulations change after the technician becomes certified; - ANSWER: The
technician is responsibility for complying with any future changes in the regulations.
Recovery equipment manufactured after November 15, 1993 must be; - ANSWER:
capable of recovering 90% of the refrigerant in the compressor os operating; 80% of
refrigerant if its not or 4 inches of vaccum
Which of the following is true of small appliances refrigerant leaks; - ANSWER: EPA
does not require repair, but leaks should be repaired whenever possible.
Recovery equipment manufactured after November 15, 1993 must be capable of
recovering; - ANSWER: 90% refrigerant or or achieving 4 inches of vacuum.
Recovering multiple types of refrigerants in the same cylinder; - ANSWER: will make
the reclaimed refrigerants non reclaimable and a charge for disposal may be levied.
Self-contained or active recovery equipment; - ANSWER: Has its own means of
recovery.
System-dependant or passive recovery equipment; - ANSWER: Captures refrigerant
into a non-pressurized container with assistance of the appliance compressor.
What is defined as a non-condensible? - ANSWER: Air
When using a system-dependent recovery system on an appliance that has an
operating compressor, the technician should; - ANSWER: Run the compressor and
recover from the high side of the system.
When using a system-dependent recovery system on an appliance that has a non-
operating compressor, the technician should; - ANSWER: Place access fitting on both
the low and high side of the system.
System-dependant devices may only be used on appliances containing; - ANSWER:
15 pounds of refrigerant or less.
, Small appliances are equipped with a straight piece of tubing (process stub) used to;
- ANSWER: install a piercing type access valve fitting.
If a strong odor is detected while performing the recovery process, - ANSWER: A
compressor burnout has likely occurred.
After the refrigerant has been recovered, which of the following can be used to flush
the system? - ANSWER: Nitrogen
When filling a charging cylinder with a regulated refrigerant; - ANSWER: The
refrigerant vapor that is vented off the top of the cylinder must be recovered.
If after installing a fitting for the purpose of recovering the appliances refrigerant,
you find that the system pressure is 0 psig; - ANSWER: Recovery is not required.
Applying heat with a heat gun to the compressor; - ANSWER: can help vaporize any
trapped liquid refrigerant during recovery.
Refrigerators in the 1950's and earlier may have used what refrigerants (recovery is
not required)? - ANSWER: Methyl Formate, Methyl Chloride, or Sulfur Dioxide.
Small appliances in recreational vehicles may use refrigerants such as Ammonia,
Hydrogen, or water, and therefore; - ANSWER: The refrigerant should not be
recovered.
Recovery equipment manufactured before November 15, 1993 must be capable of
recovering. - ANSWER: 80 percent of the refrigerant or achieving 4 inches of vacuum.
When pressurizing a system with nitrogen you should; - ANSWER: charge through a
pressure regulator;place a relief valve in the downstream line from the pressure
regulator.
After recovering refrigerant, the Nitrogen used to flush the system may be: -
ANSWER: legally vented.
The sale of CFCs and HCFC's are - ANSWER: restricted to certified technicians
ARI 740 sets - ANSWER: recovery requirements
All equipment must be equipped with - ANSWER: low loss fittings
Low loss fittings should be able to - ANSWER: close manually or automatically when
hoses are disconnected to minimize refidgerant loss
Before beginning a refrigerant recovery procedure, it is necessary - ANSWER: to
know the type of refrigerant that is in the system.
