Structural Maintenance 12-50
REMOTE EVAPORATOR UNIT
Unit Inspection
Inspect the unit during the unit pre-trip inspection and scheduled maintenance inspections. Look for loose or broken wires or
hardware, compressor oil leaks, or other physical damage that 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 airflow). Inspect the coil and fins for damage, and repair if necessary.
CAUTION: Air pressure should not be high enough to damage the coil fins.
