PROCEDURE
Step 1 Complete the "Operation Analysis" column.
Read down the left "Operational Analysis" column.
Perform all procedures and check all information listed.
Each item in this column has supporting reference
material to help analyze each step.
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 Enter Checkmarks ().
Each time the actual findings of an item in the
"Operational Analysis" column matches the published
findings on the table, enter a Checkmark.
Example: Freeze cycle suction pressure is determined to
be low. Enter a Checkmark in the "low" column.
Step 3 Add the Checkmarks 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, supporting
material was not analyzed correctly or the problem
component is not covered by the analysis table.
