SECTION 4: MAINTENANCE
4.1 Before You Begin
1.
Refer to
Appendix B, Maintenance Schedule
, for the itemized Welker recommended maintenance schedule for the
ECOsystem™.
2.
Prior to maintenance or disassembly of the unit, it is advisable to have a repair kit available for repairs of the system in
case of unexpected wear or faulty seals.
New seals supplied in spare parts kits should be lightly lubricated before being installed to ease the installation of the seals and
reduce the risk of damage when positioning them on parts. Wipe excess lubricant from the seals, as it may adversely affect analytical
instrument results.
For sample-exposed seals, Welker recommends non-hydrocarbon-based lubricants, such as Krytox®.
For non-sample-exposed seals, Welker recommends either non-hydrocarbon-based lubricants or silicone-based lubricants, such as
Molykote® 111.
After the seals are installed, the outer diameter of shafts and inner diameter of cylinders may be lubricated to allow smooth
transition of parts.
3.
All maintenance and cleaning of the unit should be performed on a smooth, clean surface.
4.2 Maintenance
1.
During operation, monitor the system for leaks. If leaks are present, halt operation and repair as necessary.
2.
Occasionally, a system component may need to be repaired or replaced for manufacturer recommended maintenance.
To perform maintenance on components:
a.
Turn OFF all electrical power to the system.
b.
Depressurize the system and close all valves.
Prior to closing odorized gas outlet valves K1 and K2 and/or the pipeline isolation valve, the ECOsystem™ must be powered down.
This is to prevent the odorant supply tank from building pressure.
c.
Disconnect the tubing and remove individual system components for maintenance.
d.
For complete and proper maintenance on individual system components, refer to their respective
Installation,
Operation, and Maintenance
(IOM)
Manual.
A list of component
Installation, Operation, and Maintenance
(IOM)
Manuals
is available in
Appendix A, Referenced or Attached Documents,
in this manual.
e.
After performing necessary maintenance on system components, reconnect all instrument tubing.
f.
Reinstall the system according to the instructions in
Section 2.2, Installation,
and
Section 2.3, Start-Up Procedures
.
