STP-H600/H1000 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-
H600C/H1000C or other models). When you use gases including alkaline metals, but
excluding Li, gases including Ga, Hg, In, or Sn, or HBr, contact Seiko Seiki.
WARNING
Check the properties of the gas to be used, referring to the Material Safety Data
Sheet (MSDS) you obtain from the gas supplier. Follow any and all safety
precautions and/or recommendations instructed by the gas supplier.
Take appropriate measures specified in the MSDS to prevent a problem if you
use any corrosive, reactive, flammable or other system gas. Dilute the pumped
gas with a monitored inert gas if necessary. Take appropriate measures so as
not to cause a problem due to the pumped gas
CAUTION
NEVER use corrosive gases (chlorine, fluorine, or other system gases) in the
STP-H600/STP-H1000 pump or other models without anti-corrosion treatment.
Introduce a dry N
2
gas (purge gas) to protect the inside of the STP pump when
using reactive or corrosive gases.
Cool the STP pump to within the operating pressure range to prevent the STP
pump from overheating when sucking gases.
1.2 Maintenance Precautions
Perform any maintenance of the STP pump and the STP control unit (battery replacement,
fuse replacement), following Section 12, "Maintenance and Inspection".
CAUTION
Always turn OFF the primary power (switch the breaker "OFF") before
performing any maintenance.
Disconnect internal battery connector before performing maintenance of the STP
control unit.
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.
