Section 12: System Maintenance
Preventative Maintenance
Schedule
A preventative maintenance program serves to an-
ticipate maintenance issues prior to waiting until the
system requires service. Like changing the oil & filters
in an automobile, by choosing to service the various
parts and operation in the NJEX System at regular
intervals, the technician can perform the maintenance
service when desired, rather than when required, such
as in the middle of night.
The key is to perform maintenance before it is re-
quired. The preventative maintenance schedule
implemented should consider the application of the
odorizer. Many of these considerations include: the
weather environment; the condition of, the actuation
gas, the odorant and the odorant bulk storage tank,
and the pump stroke frequency. All of these issues
must be considered when establishing a preventative
maintenance schedule.
