WARNING

Correct direction of wheel rotation is critical. Reversed 
rotation will result in poor air performance, motor 
overloading and possible burnout.

 3. 

Vibration Isolators:

 After fan is moved to desired 

location, punch out the four knockout holes which 
are located on the unit top and bottom panels. 
Assemble the brackets to the unit according to the 
appropriate drawings on page 5. Make certain all 
connectors are tight and that all washers are in.

 4. 

For BSQ-M Fans:

 If adjustments are made, it is 

very important to check the pulleys for proper 
alignment. Misaligned pulleys lead to excessive belt 
wear, vibration, noise, and power loss (see Figure 9).

Pre Start-Up Checks

 1. 

Check all fasteners for tightness.

 The wheel 

should rotate freely and be aligned as shown in 
Figure 7. Wheel position is preset and the unit is 
tested at the factory. Movement may occur during 
shipment, and realignment may be necessary. 
Centering can be accomplished by loosening 
the bolts holding the inlet (venturi) panel and 
repositioning. Wheel and inlet cone overlap can be 
adjusted by loosening the setscrews in the wheel 
and moving the wheel to the desired position.

 2.  

Wheel Rotation:

 

Direction of wheel 
rotation is critical. 
Reversed rotation 
will result in poor air 
performance, motor 
overloading and 
possible burnout. 
Check wheel rotation 
by momentarily 
energizing the unit (all 
SQ-M and BSQ-M 
fans have clockwise wheel rotation when viewed 
from top of fan). Rotation should be clockwise as 
shown in Figure 8 and correspond to the rotation 
decal on the unit.

Duct Length: 

The inlet and outlet duct length should be 

approximately two to three wheel diameters long before 
and after the fan to achieve cataloged performance.

Side Discharge:

 Make sure discharge is orientated in 

the same direction as originally ordered, performance 
will change with different discharge positions. Refer to 
Figure 6 for proper side discharge definition and the 
Side Discharge chart for dimensions. Refer to the CAPS 
program or consult factory for performance corrections.
