STP-200/300/400 Series Instruction Manual

1 Precautions for Safe Operation of the STP Pump

1.1 Usable Gases

Chlorine or fluorine system gases can be used in chemical specific pumps

(STP-200C/300C/400C or other models). When you use gases including alkaline

metals, but excluding Li, gases including Ga, Hg, In, or Sn, or HBr, contact BOC

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

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

◇ NEVER use corrosive gases (chlorine, fluorine, or other system

gases) in the STP-200/300/400 pump or other models without

anti-corrosion treatment.

◇ Introduce a dry N

gas (purge gas) to protect the inside of the STP

pump when using reactive or corrosive gases (See Section 7.3, "Gas

Suction").

◇ Cool the STP pump to prevent the STP pump from overheating when

sucking gases (See Section 7.2, "Cooling the STP Pump").

1.2 Maintenance and Inspection Precautions

Read through Section 12, "Maintenance and Inspection" before performing any

maintenance or inspection of the STP pump and the STP control unit (battery

replacement, fuse replacement).

◇ Always turn OFF the primary power (Switch the breaker "OFF")

before performing any maintenance.

◇ NEVER touch any portions other than those designated when

performing maintenance.

Careless touch may cause electric shock and/or a short-circuiting of

the internal circuit, resulting in product damage or a problem.
