Inspect the coil surface. Any corrosion, damage, or obstructions must be corrected.
Fill & Drift Eliminator
The FXV, FXV3, CXVB, and CXVT have PVC fill with integral drift eliminators.
Inspection & Maintenance
• Inspect and clean the fill with the integral eliminators at least quarterly.
• The inspection procedure is as follows:
– Shut-off the fan and the system pump.
– Inspect the fill for obstructions, damage and fouling.
• Remove any obstructions from the fill.
• Remove any minor fouling chemically. Contact your local water treatment consultant
for advice.
• Major fouling requires cleaning and flushing.

Water Distribution System

The spray water is distributed through a corrosion resistant polyvinyl chloride (PVC)
distribution system. The drift eliminators are made of PVC, which is impervious to rot,
decay, rust, or biological attack. Inspect and clean the spray nozzles and heat transfer
section each month.
The inspection procedure is as follows:
• Shut-off the fan, but leave the spray pump running.
• Check to see if the nozzles are producing the spray pattern shown in Figure 7.
• Clean any nozzles which are clogged. If necessary, the nozzle and rubber grommet
may be removed for cleaning.
• Inspect the coil surface. Any corrosion, damage, or obstructions must be corrected.
