Trouble-Shooting Guidelines For Separator Installation
(continued)
8. Installation:
Proper installation should always include an isolation valve between the separator purge
outlet and any purge system. This will allow for the easy removal of the purge system for
servicing without having to shut down the entire system.
Separators which feature a removable upper chamber should be installed with a spool in
order to facilitate the removal of the upper chamber (see diagram on the appropriate
product sheet).
9. Flanges/Couplings:
All flanges and/or grooved couplings should have the appropriate gasket/seal in order to
ensure a leak-free installation. All hand-hole clean-out ports and other internal access
devices should also be properly re-sealed after use.
10. Air Relief Ports:
The appropriate air relief ports should be used at start-up to expel air from the separator.
If the separator will be drained periodically or exposed to entrained air or gases from the
piping system, air vents should be permanently installed.
11. Down Stream Filtration:
The use of finer filtration (polishing) downstream from the separator is a common
application. Be aware, however, that the barrier filter (as it accumulates more solids)
causes an increasing pressure loss, which may cause the flow rate of the system to be
reduced…sometimes below the recommended flow rate of the separator. This situation
will often reveal itself when typical separable solids begin to show up regularly on the
downstream barrier filter (leading the customer to possibly believe that the separator
does not work). Always check for variations in the flow rate when down stream conditions
change.
