3 PHASE MOTOR START-UP

3 Phase Motor Start-up

How to properly start a 3 phase unit the first time or after 
changes to motor, motor starter or Electrols.

1.  Turn power on at disconnect.

Caution:  Pump has 50% chance of rotating backwards.
DO NOT ALLOW debris to enter pump.

 2.  Check for correct pump rotation:
  a.  

Standard Models:

    i.  Loosen Filtrols intake coupling and remove line.
    ii.  Place hand by Filtrols intake to determine airflow.
  b. 

 Bulldog and Bison Models:

    i.  Remove vacuum controller and main air filter from power unit.
    ii.  Place hand in Filtrols close to pump inlet to determine airflow.
 3.  Run vacuum unit long enough to determine airflow direction, then
  turn pump off.
  a.  If air blows out of inlet pipe:
    i.  Reverse any two motor wires on motor overload.
    ii.  Repeat step 3.
  b.  If air sucks into inlet pipe:
    i.  Clean any oil or debris out of Filtrols.
 4.  Complete 3 phase motor start-up
  a.  

Standard Models: 

Reinstall Filtrols inlet line

  b.  

Bulldog and Bison Models: 

Reinstall main air filter and

    vacuum controller.
