MAINTENANCE AND SERVICE
The Sample Conditioning system is designed
for minimum maintenance based on antici-
pated sample composition and conditions. A
routine maintenance program will minimize
system downtime.
Maintenance will consist of two types: pre-
ventive and corrective. Preventive consists of
monitoring certain operating parameters at se-
lected intervals and determining if corrective
maintenance is required. Following are tables
which define the expected preventive mainte-
nance. Corrective maintenance will be per-
formed on as needed basis due to an
unexpected system failure.
4-1 PREVENTIVE MAINTENANCE
Preventive maintenance activities have been
developed to maximize system availability.
These activities are extremely important to the
overall quality of the monitoring system. All
preventive maintenance activities shall be per-
formed by maintenance personnel.
The performance of the monitoring system
should be reviewed on a weekly basis for the
initial six months of operation to determine if
the preventive maintenance activities and
schedule are effective. After six months,
maintenance activities shall be added or de-
leted and the frequency adjusted, if neces-
sary, to maintain a high level of data
availability and accuracy.
4-2 CORRECTIVE MAINTENANCE
Corrective maintenance shall be initiated to
remedy any problems that may occur with the
system. In order to determine the cause of a
problem, maintenance personnel should refer
to the trouble shooting sections of the Opera-
tion and Service Manual.
4-3 MAINTENANCE LOGS
All maintenance activities performed on the
monitoring equipment shall be recorded on
maintenance log sheets and stored with the
monitoring system files.
4-4 MAINTENANCE FREQUENCY
Table 4-1 through Table 4-7 lists expected
service and maintenance intervals for the
various system components - they should be
inspected at this interval. Actual life may vary
depending on operating conditions. If any
component requires repair or replacement
more frequently than listed, then consideration
should be given to providing a more reliable or
more corrosion resistant component. Those
components not identified are not applicable
to this system.
