13.3 Maintenance and Inspection
◇ When performing maintenance and inspections of the STP pump, 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.
◇
Stop the STP pump, then turn OFF the primary power and isolate the electrical
energy source (Lockout/Tagout) on the vacuum equipment. Ensure the "POWER"
LED on the front panel of the STP pump extinguished before performing
maintenance and inspections of the STP pump.
Failure to do so may result in the inadvertent rotation of the STP pump, which
may result in an accident.
◇
DO NOT touch any place other those specified when performing maintenance or
inspecting the pump and NEVER open any panel because it could cause shock,
malfunction, or short circuit.
◇
Power OFF peripheral equipments such as a baking heater before performing
maintenance and inspections.
◇ The wipes used for clean and decontamination might become hazardous waste
depending upon the solvent. Dispose of the contaminated wipes appropriately
according to the regulations of each national and/or local government.
◇
Only Service office will replace the maintenance parts, and will execute repair and
overhaul. Contact Service office.
