Operation

WARNING
Do Not Exceed Max 
Airflow!

Do not exceed the maximum rated 
airflow for the wheel. The pressure 
drop across the wheel is not to 
exceed 1.25 inches w.g. 

 

WARNING

Toxic Hazards!

Do not use an energy wheel in an 
application where the exhaust air is 
contaminated with harmful toxins or 
biohazards, which could result in 
death or serious injury.

 

WARNING

Hazardous Voltage, 
Rotating Parts!

Disconnect all electrical power, 
including remote disconnects before 
servicing. Follow proper lockout/
tagout procedures to ensure the 
power can not be inadvertently 
energized. Secure drive sheaves to 
ensure rotor cannot freewheel. 
Failure to disconnect power before 
servicing could result in death or 
serious injury. Keep hands away 
from the rotating wheel! Contact 
with the rotating wheel could cause 
physical injury.

Energy Wheel 
Startup

1.   Set diameter seals. See “Seal 

Adjustment” on page 17.

2.  Turn the energy wheel clockwise 

(as viewed from the pulley side) 
by hand to verify that the wheel 
turns freely through its full 
rotation. 

3.  Confirm that all wheel segments 

are fully engaged in the wheel 
frame and that segment retainers 

are completely fastened. (see 
Figure 7).

4.  With hands and objects away 

from moving parts, activate the 
wheel and confirm the wheel 
rotation. The correct rotation 
direction is clockwise as viewed 
from the pulley side.

5.  Start and stop the wheel several 

times to confirm seal adjustment 
and proper belt tracking on the 
wheel rim. The correct belt 
tracking is approximately a 
quarter inch from the outer edge 
of the rim. (see Figure 8).

6.  If the wheel has difficulty starting, 

turn off the power and inspect for 
excessive interference between 
the wheel surface and the four 
diameter seals. To correct, loosen 
the diameter seal adjusting 
screws and back the diameter 
seals away from the surface of 
the wheel. Apply power to 
confirm that the wheel rotates 
freely. Readjust and tighten the 
seals according to instructions in 
“Seal Adjustment” on page 17.

7.  

Damper actuators (if so equipped):

 

Stroke the actuators to observe 
full open and full closure of 
dampers. Adjust the actuator and/
or linkage to prevent “over-
stroking” so excessive pressure is 
not placed on the damper at the 
full open or full closed position.

.

Figure 7. Completely fasten 
segment retainers

Figure 8. Confirm proper belt 
tracking on the wheel rim
