Service Options
Agilent pumping systems will provide many years of trouble-free operation if the
maintenance procedures are observed.
Pumping System cleaning and internal scroll pump tip seal replacement are
recommended when Pumping System TMP adsorbed current (with blanked inlet
flange) has risen to an unacceptably high level (>500 mA) or when the message
“TIP-SEAL SERV” appears on the TPS-compact front side display.
The warning message appears after 5000 h of operation.
If your TPS-compact exhibits humming or grinding noises from the scroll pump, a
major overhaul should be done by Agilent Vacuum Technologies.
The parts needed for Tip-Seal replacement on the internal scroll pump are available
in the kit described in Orderable parts Table. This kit contains seals and O-rings, and
can be obtained from your Agilent dealer.
