Installation
(1) The pump may malfunction if it is subjected to shocks or tipped over on its side.
(2) Do not place objects on, or stand on, the pump. A malfunction may result if the pump is
handled in this manner.
(3) When carry a pump, do not have a fan cover. A fan cover may be damaged.
Applications
(4) This pump is not designed to be corrosion-proof. Use it only with clean air at normal
temperature, or with gases of equivalent characteristics.
(5) This pump is designed solely for vacuum extraction. Operation for long periods at
near-atmospheric pressures may result in a malfunction.
(6) 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.
(7) Entry of gases containing dust and particles may prevent normal operation of the pump.
Operation
(8) Use the pump within an ambient temperature range of 40°C. Use at high ambient
temperatures will dramatically reduce the life of the pump.
(9) Back pressure at the outlet while the pump is starting may overload the motor.
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.
