11.3.4 Inspecting for Deposit
Leaving the STP pump without removing the deposit may cause the
STP pump to be corroded beyond repair.
Deposit may have accumulated inside the STP pump depending upon the type of the
vacuum equipment installed to the STP pump.
An increase in the amount of deposit may lead to a malfunction of the STP pump.
Therefore, perform regular maintenance (once every 3 to 6 months).
Inspect the inside of the outlet port flange for adhesion of deposit while watching the
outlet port flange. If deposit has accumulated to some extent, an overhaul (cleaning) is
required.
Contact Service office.
Note that the costs of troubleshooting problems resulting from deposit will be at your
own charge even during the warranty period.
If a problem resulting from deposit occurs inside the STP pump, hermetically seal the
inlet port, outlet port, purge port, and leak port flanges, and immediately return the
pump to Service office.
For the transport method, see Section 11.3.6, "Transporting for Repair or Overhaul.”
