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.
(2) Not be used with toxic gases. 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.
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.
Power Supply
(4) Always remove the power cord 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) Remove the power cord socket before connecting any 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.
(10) Touching the power cord with wet hands may result in electric shock.
(11) Touching electrical wiring etc while inserting the power plug may result in electric shock.
