CLEANING CONDENSER COILS

Condenser coils should be cleaned at least
once per month . Additional cleaning may
be needed depending on the operational
environment . A dirty condenser blocks normal
airflow through the coils .
Airflow blockage increases energy
consumption and reduces the merchandiser's
ability to maintain operating temperature .
Disconnect the power cord .
Remove the two screws of the front panel,
then pull out the panel .
Remove the 8 screws in the area shown by the
figure .
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris . Do not bend
coil fins . Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles .
