NSTALLATION

1.  Verify that power is disconnected to the venter motor leads and that the source is 

locked out appropriately. 

2.  After inspecting the motor and blower wheel for shipping damage, grasp the motor 

assembly and carefully insert the blower wheel into the venter body, using caution to 
avoid damaging the wheel or displacing balancing weights.  Grasp the wheel heat 
shield and guide it onto its mounting studs, then guide the motor bracket onto its 
three mounting tie rods.  (See Figure 11)  While supporting the motor, place a lock 
washer and nut on the uppermost tie rod end and fasten finger tight.  The motor 
assembly will now 'hang' by the uppermost tie rod and may be released. 

3.  Place the remaining (2) lock washers and nuts on their respective tie rods and fasten 

finger tight.
