Section 8: System Maintenance
Preventative Maintenance
Schedule
A preventative maintenance program serves to
anticipate 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 LVO System at regular intervals, the tech-
niciancan 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
required. The preventive 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.
