the operating conditions and environment of the particular installation. Please have the motor
replaced when operation becomes abnormal.
(4)Maintenance of plastic parts affecting operational safety
Replace the following plastic parts affecting operational safety promptly upon detection of
breakage or deformation. Failure to do so may cause personal injury.

vapor and dew condensation.
Operation noise *5 dB 64 67
*1 Designed Pumping Capacity: Theoretical value calculated from volume. Refer to Performance
Data for actual flow rate.
*2 Recommended range: Vacuum/pressure range the pump can exert its optimal performance (life,
operation noise, etc.). In case high degree of vacuum/pressure is not required, operate at
recommended range.
*3 Maximum value: The maximum degree of vacuum/pressure pump can continuously run. Do not
operate pump continuously over this limit. Doing so will shorten pump life and can lead to
premature failure or accidents.
*4 Setting for thermal protection is only as a guide regardless of variations of product performance.
*5 Operating noise level is only an actually measured value under continuous operational vacuum
and continuous operational pressure, and not guaranteed.

4. Precautions
(1) Observe precautions, and operate the product within specifications.
(2) Read the instruction manual prior to installation, operation, maintenance and inspection of
the product. Especially pay attention to safety.
(3) The vanes may get damaged if the residual pressure reverses the rotation when the pump
stops. A check valve must be installed within 50 cm from the inlet port or exhaust port for
protection.
(4) Be sure to install the product horizontally on the flat surface.
(5) Operating the product in an enclosed space may cause malfunction due to heat generated
from the pump. Provide good ventilation around the product, so the ambient temperature
does not exceed the permissible level.
(6) Be sure to clean the filters periodically. Failure to do so may cause clogging and result in
trouble due to overload.
(7) Wiring work has to be performed by qualified personnel according to applicable laws and
in-house regulations.
(8) Be sure to install an overload protection such as a thermal relay in the electric circuit.
(9) Allowable intermittent power supply voltage fluctuation range is ±10% of the specified voltage;
allowable sustained supply voltage fluctuation range is ±5% of the specified voltage.
(10) Be sure to use the product 1,000m or below above sea level.
