13. Do not allow any foreign material to intrude into the blower.
14. The rotation direction shall be the arrow direction on the casing. The rotation direction can be seen
at the shaft end at counter-blower side and it is also correct, if the wind direction coincides with the
IN and OUT indicated at the pipe connection port. Reverse rotation is allowed, although the
performance is reduced.
15. Connect the power cables by using gland or electrical conduit at wiring hole of the terminal box to
protect dust, foreign objects, water and etc. into the terminal box inside. Do not remove the unused
rubber bushes of VFZ501
䌾
VFZ901. Do not use the rubber bushes to wiring.
16. Take care of edge of wiring holes at the terminal box. An
INJURY
is feared.

7. If the Vacuum Pump (VFZ401A and larger) is operated with the discharge side closed,
the motor and blower temperature rises drastically and its distortion or damage after
long time operation is feared.
8. If the Vacuum Pump is operated at a wind flow rate not more then continuous
operation range, the motor and blower temperature rises drastically and its distortion
or damage is feared, if the operation is continued for along time.
9. The temperature of the air passing through the Vacuum Pump rises. Especially it
reaches a high temperature at a nearly closed condition. Take care not to touch it by
your hand or body. A
BURN
is feared. Figure 6 shows the temperature rise.
10. During its operation, the Vacuum Pump and discharged air will reach a considerably
high temperature. Do not use it in a narrow closed room. A
BURN
, a
FIRE
or
