STP-200/300/400 Series Instruction Manual

12.4 Inspecting for Deposit

◇ When inspecting for deposit, exhaust gases inside the STP pump

thoroughly.

Residual gases may cause an accident when removing the STP

pump.

Confirm the characteristics of gas to be used, referring to the

Material Safety Data Sheet (MSDS) you obtain from the gas supplier.

Wear personal protective equipment if necessary.

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).

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 12.6, "Transport for Repair or Overhaul."

◇ Contact with atmospheric air may cause a reaction of the deposit.

DO NOT open the STP pump to atmospheric air as much as possible.
