h. Maintenance
Condenser Fins
Condenser fins become dirty over time as ambient air is induced to the
condenser. Dirty coil surfaces result in high condensing temperatures and
poor unit performance. Regular cleaning is recommended with frequency
depending on the installation and the surrounding environment. As a general
guide, it is advisable to do this at least once every two months.
Fins should be cleaned with liquid detergent diluted with clean water. Before
washing, a light brush downward (in the direction of the fins) should be done
to remove heavy deposits.
Electrical Connections
Check tightness of electrical connections occasionally.
Routine Leak Test
All joints should be checked for leaks during site visits. All joints should be
leak tested once a year. Condenser Fan(s) and Motor(s), an annual inspection
of these items is recommended. Fastenings may loosen, bearings may wear,
and fans may require cleaning of solid deposits which can cause imbalance.
TURN OFF OR DISCONNECT THE ELECTRICAL POWER SOURCE BEFORE
CLEANING THE CONDENSER COIL OR DOING MAINTENANCE
