STP-H803/H1303 Series Instruction Manual
11.6.2
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, purge port, and leak port flanges, and immediately
return them to Service office.
For the transport method, see Section 11.6.4, "Transport for Repair or Overhaul."
