Air exhaust port
Do not narrow an air exhaust line (for example by reducing the tube I.D.). Or the residual pressure in the pump
may deform the bellows.

Leak sensors
The sensors occasionally fails to detect leakage depending on operating conditions. Contact us for detail.
Ambient temperature
Observe the allowable operating ambient temperature range of 0-40
C.
Pump surface temperature
Risk of burning. The surface temperature of the pump or pipe rises high along with liquid temperature in or
right after operation. With the FW-20H, for example, a cylinder surface temperature rises up to 75ºC when
liquid temperature is 180ºC and ambient temperature is 17ºC.

Noise from pump
Exhaust noise accompanies pump operation. Provide noise insulation as necessary. With the FW-20H, for
example, a noise level rises up to 70.7dB (A) at 120spm and 0.5MPa (supply air pressure).
