Maintenance and Repair
(8)
If the pump ceases operation, turn power OFF immediately to prevent accidents, remove the
power cord from the wall outlet, and contact your dealer or the manufacturer for inspection and
repair.
(9) Leave the pump for at least 30 minutes until it has cooled, and begin operation again. Touching
the pump immediately after it has stopped may result in burns.
Installation
(1) The pump may malfunction if it is subjected to shocks or tipped over on its side.
(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.
(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 7
– 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) 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.
