9.4 Basic Inspection
• Perform the following inspection before disassembly.
(1) Inspection of plate fins
• To inspect the plate fins of the evaporator, open
the front panel door, and inspect the plate fins
for any dirt, dust, lint, or debris that may have
caused insufficient cooling performance of the
unit. If cleaning of the fins is necessary, it is
recommended that this service be performed
by a qualified service technician.
(2) Examination of operating environment
• Operating environments can vary depending on location, climate and surrounding conditions.
Installation location also can cause operational problems. Consult your reseller concerning
operational environment requirements.
(3) Inspection of cooling capacity performance
• Measure the difference in temperature between the inlet of the evaporator and the cool air vent.
If the difference is out of the range given in the graphs on page 14, proceed with the remedy
suggested in the troubleshooting chart on page 42 to 46.
