Procedure
Step 1
Complete each item individually in the
“Operational Analysis” column.
Enter check marks (  ) in the boxes.
Each time the actual findings of an item in the
“Operational Analysis” column matches the published
findings on the table, enter a check mark.
Example: Freeze cycle suction pressure is determined to
be low. Enter a check mark in the “low” box.
Perform the procedures and check all information listed.
Each item in this column has supporting reference
material.
While analyzing each item separately, you may find an
“external problem” causing a good refrigerant component
to appear bad.
Correct problems as they are found. If
the operational problem is found, it is not necessary
to complete the remaining procedures.
Step 2
Add the check marks listed under each of the
four columns. Note the column number with the highest
total and proceed to “Final Analysis.”
NOTE: If two columns have matching high numbers,
a procedure was not performed properly and/or
supporting material was not analyzed correctly.
