12. 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. 

 
 
13. 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.   

 
 
14.  Take care of edge of wiring holes at the terminal box. An 

INJURY

 is feared.

machine may run suddenly at the power restoration.

 

 

   

Alarm 

4.  If any abnormality occurs, stop the operation immediately and turn the power supply 

switch off. An

7.  If the Ring Blow is operated with closed condition, the motor and blower temperature 

rises drastically and its distortion or damage after long time operation is feared. 

8. If the Ring Blow 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 Ring Blow 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.
