Installation
(1) The pump may malfunction if it is subjected to shocks or tipped over on its side.
Applications
(2) This pump is not designed to be corrosion-proof. Use it only with clean air at normal
temperature, or with gases of equivalent characteristics.
(3) This pump is designed solely for vacuum extraction. Operation for long periods at
near-atmospheric pressures may result in a malfunction.
(4) 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.
(5) Entry of corrosive gases, organic solvents, fluids, or gases able to be condensed (eg.
steam) may result in damage to the pump and prevent normal operation.
(6) Entry of gases containing dust and particles may prevent normal operation of the pump.
Operation
(7) Use the pump within an ambient temperature range of 7
~
40°C. Use at high ambient
temperatures will dramatically reduce the life of the pump.
(8) Back pressure at the outlet while the pump is starting may overload the motor.
(9) The thermal protection relay operates when the pump reaches a very high temperature.
Touching the pump in this condition may result in burns.
Maintenance and Repair
(10) The fine clearances used in this pump require skill in its assembly. If a repair technician
is unavailable, replacement of all consumables should be left to the manufacturer’s
service division.
