D.8. COPPER COIL UNIT
The copper coil unit should be inspected annually or as needed, and cleaned as required.
Remove the service door(s) for copper coil(s) unit(s) access and unscrew bolts that support the coil, located at
either side, down on each slide-angle that supports the copper coil unit. Then, in case you are located on the
ground; place a forklift right in front of a lengthwise set of forks that totally cover the unit size. Should the
tower be in a roof area, use a mobile oor crane with the right load capacity, and a steel work table as an
hook device see Table D-4 for Copper Coil Unit(s) total weight by model. Finally pull the coil out carefully,
avoiding contact with tower body to prevent any damage. (See Figures D-1 and D-2 for reference.)
Place the cooper coil unit in a well lighted open room, and proceed as follows:
1. Blow compressed air across the coil, use a plastic brush to wash and remove the debris accumulated
out off the coil.
2. Use a pressure washer to spray fresh water and remove the silt, mud or slime for the coil.
3. The use of cleaning agents must follow the manufacturer’s directions for proper mixing and cleaning.
Verify there are no chemical residues still remaining in the coil after the cleaning process.
4. The rinsing process is important to avoid, the clean agent residue could initiate a corrosion process.
5. If the Closed Circuit Fluid Cooler is located in a very aggressive environment, periodic cleaning
process must be required.

The chemical treatment supply connection is not factory installed. This connection must be installed
on the basin (below the copper coil) to dilute the chemicals in the water. Direct exposure of the
copper coil to the chemicals may accelerate corrosion.
