8 ROUTINE MAINTENANCE
Ensure the following for optimum performance:
1.
Carrier flow is the value specified for your configuration. To check the carrier
flow, put the injection mode in manual. Return to
RUN
menu and watch the
value. It is normal to have carrier flow deviation during a cycle. Between and
before an injection the carrier flow must be correct.
2.
From time to time, verify the oven temperature in the diagnostic menu. It must
be constant and at the value specified for the analyser configuration.
3.
The sample flow must be the same value as for the previous calibration
procedure. This will ensure the same sample volume is injected. The default
value is 50 cc/min per channel.
4.
Clean the cabinet fan filter periodically. This will support effective cooling and
avoids problems caused by high internal temperature.
5.
An Auxiliary oven will be used with some applications with O2 and H2
background gases. The trap in this oven will require replacing periodically,
dependent on the application (typically every 2 years)
6.
The SERVOPRO Puregas gas purifier will require replacement periodically,
dependent on the application (typically every 2 years).
7.
The permeation tube (fitted with each PED) will require replacement
periodically, dependent on application (typically every 5 years). Please contact
