Spray Nozzles And Heat Transfer Section

The spray nozzles and heat transfer section should be inspected and
cleaned each month. The inspection procedure is as follows:
1. Shut off the fan, but leave the pump running.
2. Remove the eliminators.
3. Check to see if the nozzles are producing the spray pattern shown
in Figure 8.
4. Clean any nozzles which are clogged. If necessary, the nozzle and
rubber grommet may be removed for cleaning.
5. Inspect the coil or wet deck surface. Any corrosion, damage, or
obstructions must be corrected.
