13.3.2 Inspecting the 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 in 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 three to six months as a target).
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 inlet
port, outlet port, or purge port, immediately return them to Service office. For the
transport method, see Section13.4.4, "Transport for Repair or Overhaul".

◇ Contact with atmospheric air may cause a reaction of the deposit. DO NOT open
