The evacuation table splits several of its rows into a column for equipment built before November 15, 1993 and a column for equipment built on or after that date. Which piece of equipment's build date decides which column a technician reads?
Correct Answer
C) The date the recovery or recycling equipment was manufactured
The November 15, 1993 split describes recovery and recycling machines, not appliances. Machines built on or after that date had to meet tougher performance standards, so the table holds them to deeper levels. A brand new rooftop unit worked with a 1990 machine is held to the older column, and a nineteen eighties chiller worked with a modern machine is held to the newer one. Reading the date off the appliance instead of the machine reverses the answer on most large jobs.
Why This Is the Correct Answer
The two columns exist because equipment standards changed. Recovery and recycling equipment manufactured on or after November 15, 1993 had to be certified against a tougher standard, and the evacuation table asks those machines to reach deeper levels. The technician therefore looks at the date plate on the recovery machine to choose the column, and at the appliance only to choose the row.
Why the Other Options Are Wrong
Option A: The date the appliance being serviced was manufactured
This reverses the rule. The appliance's own age has no bearing on the required level; only its refrigerant and its normal charge place it on a row.
Option B: The date the appliance was last charged with refrigerant
When an appliance was last charged says nothing about which standard applies. No line of the evacuation table turns on service history.
Option D: The date the technician's certification was originally issued
Certification date affects nothing about evacuation levels. A technician certified last month and one certified in 1994 read the same table the same way.
Memory Technique
The machine picks the column, the appliance picks the row. Two plates, two jobs.
Reference Hint
The November 15, 1993 split in the evacuation table refers to the build date of the recovery or recycling equipment.
