6.9 Basic Inspection
• Perform the following inspection before disassembly.
(1) Inspection of plate fins
• To inspect the plate fins of either the
evaporator or condenser, the air filter must be
removed. After removal of the air filters, 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 10, proceed with
the remedy suggested in the troubleshooting
chart on page 50 to 55.
