Structural Maintenance
UNIT INSPECTION
Inspect the unit during the pre-trip inspection and during
scheduled maintenance inspections for loose or broken
wires or hardware, compressor oil leaks, or other physical
damage which might affect the unit performance and
require the repair or replacement of parts.
EVAPORATOR COIL
Clean the evaporator coil during scheduled maintenance
inspection by blowing compressed air down through the
coil out into the box (direction opposite the normal air
flow). Inspect the coil and fins for damage and repair if nec-
essary (requires removing the evaporator fan and front
cover).
CAUTION: Air pressure should not be high enough
to damage the coil fins.
FAN LOCATION
When mounting the fan and hub assembly on the fan shaft,
position the assembly in the orifice with 30 to 35 percent of
the blade width to the air discharge side for proper fan per-
formance.
