Note
Installation
(1) Application of shock to the pump, or allowing it to fall over, may result in a malfunction.
(2) Do not grip or bend the tube on the side of the pump. Any damage to this tube may
reduce the performance of the pump.
(3) Fit an inlet filter if there is a possibility of foreign matter or dust particles entering the
pump.
(4) Use ventilation holes, and fit a cooling fan, to reduce the temperature in the vicinity of
the pump. Ensure that the pump cooling fan inlet is not blocked. Ensure that a space of
at least 100mm is available on all sides of the pump.
Application
(5) This pump is not designed to be corrosion-resistant. It should only be used with clean
air at normal temperatures, or gases with equivalent characteristics.
(6) This pump is only for vacuum pumping. Use at near-atmospheric pressures for long
periods of time may result in a malfunction.
(7) In addition to discharge of gas via the pump outlet, gas may leak from the pump itself.
Do not use the pump to evacuate toxic gases. If the pump is used to evacuate toxic
gas, appropriate care is required during maintenance.
(8) The pump will not often operate normally if it is used with corrosive gases, organic
solvents, liquids, or condensed gases (eg steam).
(9) The pump will not often operate normally if it is used with gases containing particles or
dust etc. Always fit a filter to the inlet.
Operation
(10) Use the pump at an ambient temperature of 0-40°C. The life of the pump will be
severely reduced if it is operated at high temperatures.
(11) Application of back pressure at the pump outlet will overload the motor and may
prevent the pump starting.
(12) When the thermal protection relay operates the pump will be extremely hot. Touching
the pump in this condition may result in burns.
Maintenance and Repair
(13) This pump operates with precision clearances and therefore requires particular skill for
assembly. If a repair technician is not available, contact the manufacturer's service
division for replacement of consumables.
