| Question | Answer |
|---|---|
| If a strong odor is detected while performing a refrigerant recovery process | A compressor burn out has likely occurred |
| Technicians who perform sealed system service on small appliances must have; | Type 1or universal certification |
| When a system is in deep vaccum; | Never energize the compressor |
| If regulations change after the technician becomes certified; | The technician is responsible for complying with any changes to the regulations |
| Recovery equipment must be; | Certified by an epa approved testing lab |
| Small appliances in recreational vehicles may use refrigerants such as Ammonia,hydrogen,and water.these refrigerants; | Should not be recovered |
| System dependent recovery methods may only be used on appliances containing; | 15 pounds of refrigerant or less |
| On a system with an operating compressor,recovery equipment must be capable of recovery | 90% or achieving 4 inches of vacuum |
| When pressurizing a system with nitrogen you should; | Both charge through a pressure regulator and install a relief valve in the line downstream from the pressure regulator. |
| With a non operating system compressor,recovery equipment must be capable of recovery; | 80 percent of the refrigerant or achieving 4 inches of vaccum |
| A small appliance is defined by epa as | Appliances manufactured,charged,and hermetically sealed in a factory that contain 5 lbs of refrigerant |
| Type 1 certification is required for; | Persons handling refrigerant during maintenance,service,or repair of small appliances |
| Which of the following is an example of a non commendable ? | Air |
| 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 |
| System dependent or passive recovery equipment; | Captures refrigerant into a non pressurized container |
| After the refrigerant has been recovered,which of the following can be used to flush the system? | Nitrogen |
| Which hc refrigerant is allowed for use in New domestic small appliances? | R-600a |
| Recovering multiple types of refrigerants in the same cylinder; | Will make the reclaimed refrigerants unreclaimable |
| 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 |
| If after installing a fitting for the purpose of recovering the appliances refrigerant,you find that the system pressure is 0 psig | Refrigerant recovery is not required |
| When filling a charging cylinder with a regulated refrigerant; | The refrigerant vapor that is vented off the top of the cylinder must be recovered |
| Applying heat,with a heat gun,to the compressor; | Can help vaporize any trapped liquid refrigerant during recovery. |
| When using a system -dependent recovery system on an appliance that has a non operating compressor,the technician should; | Place access fitting in both the low and high side of the system |
