In case of trouble, perform the following inspection
before disassembly.
6. Inspection of Plate Fins
To inspect the plate fins of either the evaporator
or condenser you must remove the air filters.
After removal of the air filters, inspect the plate
fins for any dirt, dust, lint, or debris that may have
caused poor cooling performance of the unit. If
cleaning of the fins is necessary, it is recom-
mended that this service be performed by a
qualified service technician.

Operating environments will vary depending on
location, climate and surrounding conditions.
Installation location also can cause operational
problems. Consult your reseller concerning
operational environment requirements.

inlet of the evaporator and the cool air vent. If the
difference is out of the range given in the graphs on
