INSPECTION LOG
Figure 5.2 depicts a Sample Operational Log for the RO unit. The operator of the RO
unit should establish a program for entering the required data on a regular basis.
Maintaining accurate operational data is the first, and most important, step in
determining preventative maintenance requirements and reducing system
downtime. Figure 5.3 depicts a Sample Discrepancy Report that may be used for
reporting and tracking problems with the RO unit.
