Cautions for Safety in Use
Applications
(1) This pump is not designed to be explosion-proof, and should therefore not be used to
discharge explosive gases. Such use may result in injury and fire.
(2) In addition to discharge of gas via the outlet, gas may also leak from other parts of the pump,
and it should therefore not be used with toxic gases. If toxic gas is discharged for any reason
it is important to note that the interior of the pump will be contaminated by the gas, requiring
appropriate caution during maintenance.
Maintenance and Repair
(3)
When requesting the manufacturer’s service division to dismantle and repair the pump, always
note the gas which the pump has been used with on the Usage Check Sheet. Note that if it
has been used to discharge toxic gas for any reason it will be contaminated. Please be aware
that use with some gases will preclude dismantling and repair.
(4) Before maintenance disconnect the pump by the plug or the installed disconnection device.
Operation
(5) Do not use the pump to suck corrosive gas, organic solvent, liquids, or condensable gas
(water vapor, etc.).
Installation
(1) Do not use the pump in an explosive atmosphere. Such use may result in injury and fire.
(2) Ensure that there are no inflammable materials such as solvents in the vicinity when using
the pump.
(3) Ensure that the pump is freely ventilated to prevent overheating, which may result in fire or
burns.
(4) To be used with clean air only.
