G-Condenser Coil
All-Aluminum Coils -
Clean condenser coil annually with water and inspect
monthly during the cooling season.
Clean the all-aluminum coil by spraying the coil steadily
and uniformly from top to bottom. Do not exceed 900 psi
or a 45î angle; nozzle must be at least 12 inches from the
coil face. Take care not to fracture the braze between the
fins and refrigerant tubes. Reduce pressure and work
cautiously to prevent damage.
Fin/Tube Coils -
Clean condenser coil annually with detergent or
commercial coil cleaner and inspect monthly during the
cooling season.
Condenser coils are made of single and two formed slabs.
On units with two slabs, dirt and debris may become
trapped between the slabs. To clean between slabs,
carefully separate coil slabs and wash them thoroughly.
See figure 36. Flush coils with water following cleaning.
Note - Remove all screws and gaskets prior to cleaning
procedure and replace upon completion.
