Cautions for Safety in Use

Danger
!
Applications
(1) This pump is not designed to be explosion-proof, and should therefore not be used to
discharge explosive gases.
(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 Status 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.
! Warning
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 motor is freely ventilated to prevent overheating which may result in fire or
burns.
Power Supply
(4) Always remove the power cord from the terminal before checking or repairing the pump.
Failure to do so may result in electric shock, or the pump suddenly starting and causing
injury.
(5) Ensure that the relevant wiring is in accordance with technical standards for electrical
equipment and wiring regulations. Incorrect wiring may result in fire.
(6) Always remove the power cord from the terminal before electric wiring. Connecting wiring
with the power on may result in electric shock.
(7) Always ensure that the pump is correctly earthed. A dedicated earth leakage breaker is
recommended. Failure to earth the pump correctly may result in electric shock if a fault or
earth leakage occurs.
(8) Use the pump only at the rated voltage. Use at other than the rated voltage may interfere
with operation of the overload protection device, and this may result in the motor burning
out, or fire.
(9) Do not damage, modify, pull the power cord, or place objects on it. Damage to the cord may
result in electric shock or fire.
