Remote Evaporator Structural Maintenance
Unit Inspection
Inspect the unit during the unit pretrip inspection
and scheduled maintenance inspections for loose
or broken wires or hardware, chaffed wires,
compressor oil leaks, or other physical damage
which might affect unit performance and require
repair or replacement of parts.
Defrost Drains
Clean the defrost drains during scheduled
maintenance inspections to make sure the lines
remain open.
Evaporator Coil
Clean the evaporator coil during scheduled
maintenance inspections by blowing compressed
air from the top side of the coil down toward the
bottom (the direction opposite the normal air
flow). Inspect the coil and fins for damage, and
repair if necessary.
CAUTION: Air pressure should not be
high enough to damage the coil fins.
