Back 7

75 psig.

Front 8

All recovery devices manufactured BEFORE November 15, 1993 for use with small appliances must meet which of the following requirements?

Back 8

Capable of recovering 80% of the refrigerant whether or not the compressor is operating or achieving a 4 inch vacuum under conditions of ARI 740.

Front 9

Small appliance recovery equipment manufactured AFTER November 15, 1993 must be certified to be capable of;

Back 9

recovering 90% of the refrigerant when the compressor is operating or achieving a 4 inch vacuum under the conditions of ARI 740.

Front 10

When servicing a small appliance for leak repair;

Back 10

It is not mandatory to repair the leak but do so whenever possible.

Front 11

After recovering refrigerant from a sealed system, if nitrogen is used to pressurize or blow debris out of the system, the nitrogen;

Back 11

may be vented.

Front 12

A. Recover 95% of the refrigerant whether or not the compressor is operative.

B. Recover 80% of the refrigerant with an inoperative compressor.

C. Recover 90% of the refrigerant with an operative compressor.

Back 12

D. Both "B" and "C".

Front 13

When R-500 is recovered from an appliance, it;

Back 13

must be recovered into its own recovery vessel that is clearly marked to ensure that mixing of refrigerants does not occur.

Front 14

It is generally recommended that piercing-type valves be used on which of the following tubing materials?

A. Copper.

B. Aluminum.

C. Steel.

Back 14

D. Both "A" and "B".

Front 15

Which refrigerants can be mixed?

A. R-11 and R-12.

B. R-12 and R-134a.

C. R-12 and R-22.

Back 15

D. None of the above.

Front 16

A storage cylinder of recovered R-22 at normal room temperature (about 75 degrees F), in the absence of non-condensables, will be pressurized to;

Back 16

130 psig.

Front 17

Refrigerants (i.e., R-12, R-22, R-500, etc.) in large quantities can cause suffocation because;

Back 17

they are heavier than air and displace oxygen.

Front 18

Since small amounts of CFC/HCFC refrigerant have no odor, when a pungent odor is detected during a sealed system recovery and/or repair;

Back 18

a compressor burn-out has likely occurred.

Front 19

If a reclamation facility receives a tank of mixed refrigerant, they may;

A. refuse to process the refrigerant and return it at the owner's expense.

B. agree to destroy the refrigerant, but typically a substantial fee is charged.

C. resell the refrigerant for reuse in its current state.

Back 19

D. Both "A" and "B".

Front 20

At high temperatures, (i.e., open flames, glowing metal surfaces, etc.) R-12 and R-22 can decompose to form;

Back 20

hydrochloric and hydrofluoric acids.

Front 21

A storage cylinder of recovered R-500 at normal room temperature (about 75 degrees F), in the absence of non-condensables, will be pressurized to;

Back 21

95 psig.

Front 22

When a household refrigerator compressor does not run, it is recommended that low and high side access valves be installed when recovering refrigerant from the system because;

A. it can enhance the speed of recovery.

B. it may be necessary to achieve required recovery efficiency.

C. otherwise, the refrigerator's compressor may be damaged.

Back 22

D. Both "A" and "B".

Front 23
