3.2 Environmental Conditions for Installation, Storage, and Operation
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 (during storage and operation).
a) Level floor of sufficient strength.
b) No condensation
c) Dust-free environment
d) Well ventilated
e) Environment free of corrosive or explosive gas.
f) Not subject to direct sunlight.
g) No danger of fire.
h) Maximum ambient temperature of 40°C during assembly of pump.
3.3 Location
The pump should be installed level in a location with minimal dust and humidity. This location
should be selected in consideration of ease of installation and removal, inspection, and cleaning.
Particular attention should be paid to ambient temperature when fitting the pump to equipment.
Use anti-vibration rubbers to isolate the pump from vibrations in the equipment. See 3.2
Environmental Conditions for Installation, Storage, and Operation for details.
3.4 Checking Operation After Installation
1) Remove the rubber caps from the inlet and outlet.
2) Check that the pump switch is OFF (set to O), and insert the plug into the 100 V wall socket.
Caution: Ensure that the power plug is sufficient for the rated voltage and current.
Caution: Extension cords should be 3-wire, with lead wires having a cross-sectional area of
at least 0.75 mm
3) Turn the switch ON (set to l) and check that gas is being drawn into the inlet.
4) When this check is complete, turn the power switch OFF (set to O) to stop the pump.
3.5 Piping
1) Install piping carefully to prevent leaks.
2) Piping connected to the inlet should be at least 6 mm inside diameter.
3) Ensure that piping connected to the outlet does not cause back pressure. Maximum back
pressure is 0.03 MPa (gauge pressure).
4) In case of selecting the inlet pipe and exhaust pipe that are not from our products, please
select the exhaust pipe that has same or larger inner diameter length with the inlet pipe.
5) When evacuating a vessel, ensure that a shut-off valve is placed between the pump inlet pipe
and the vessel (see Fig.3.1).
