Installation
(1) Microscopic particles resulting from wear of components are discharged from the outlet and
contaminate the room. If necessary, connect a pipe from the discharge outlet to the outside
of the building.
(2) The fine clearances used in this pump require that the following conditions be satisfied during
storage, installation, and operation.
1. Ambient temperature of 0~40°C and maximum relative humidity of 85% during
operation.
2. Other conditions for storage and operation.
a) Level floor of sufficient strength.
b) No condensation
c) Dust-free environment
d) Location with no oil smoke or oil droplets.
e)
Location with no splashes or not submerged in water.
f) Environment free of corrosive or explosive gas.
g) Not subject to direct sunlight.
h) No danger of fire.
i) Maximum ambient temperature of 40°C during assembly of pump.
j) Instead of installing the vacuum pump directly onto a base, always place a vibration
absorption rubber mat between the pump and the base.
k) Well ventilated
Power Supply
(13)Due to the safety function on the driver board, this pump automatically stop when it detects
overloading or locked state. For better safety, make sure that the machinery, on which the
pump is mounted, is also equipped with some kind of safety device to automatically
disconnect the power when it detects overloading or locked state.
(14)The DC24V power supply must be supply from device which pump is built in.
Operation
(15)This pump is not designed to be explosion-proof. When using the pump, ensure that there
are no inflammable materials such as solvents, or explosive gases, in the vicinity. Use under
such conditions may result in injury or fire.
(16)Operating the pump with the discharge outlet blocked, or with a device which prevents
passage of gas to the discharge outlet, may result in rupture of the pump. The internal
pressure of the pump rises and the pump body may rupture and the motor become
overloaded.
This pump is not designed to be pressure-resistant. The internal pressure of the pump is
limited to 0.03 MPa (gauge pressure).
Maintenance and Repair
(17) Always turn off the DC 24V power supply of the pump before maintenance or the repair.
(18) The pump should be dismantled or repaired only by a repair technician trained by the
manufacturer.
(19)To prevent ingestion of microscopic particles resulting from wear of components, use a dust
mask and gloves when replacing diaphragms and valves.
