Preventative Maintenance
Schedule
A preventative maintenance program serves to antici-
pate 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 required.
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 fre-
quency. All of these issues must be considered when
establishing a preventative maintenance schedule.
