Structural Maintenance
Unit Inspection
Inspect the unit on pre trip and regular scheduled maintenance for loose or
broken wires and 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 and out (opposite the normal air flow).
Inspect the coil and fins for physical damage and repair if necessary.
Note: Air pressure should not be high enough to damage coil and fins.
Safety Note: When blowing down, wear safety glasses.
Condenser Coil
Clean the condenser coil during regular scheduled maintenance by blowing
compressed air or washing with mild soap and water down through the coil
(opposite the normal air flow). Inspect the coil fins for physical damage and repair
if necessary.
Note: Air pressure and water pressure should not be high enough to
damage coil and fins.
Mounting Bolts
Periodically check and tighten all mounting bolts.
