8. 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.
Energy Wheel Startup
Note: 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.
1. Set diameter seals. See “Energy Wheel Seal
Adjustment,” p. 160.
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 170).
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.
WARNING
Toxic Hazards with Exhaust Air!
Failure to follow this instruction could result in death or
serious injury. Do not use an energy wheel in an
application where the exhaust air is contaminated with
harmful toxins or biohazards. Using an energy wheel
could displace vast quantity of contaminated air which
could result in asphyxiation and poisoning.
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with an appropriate
voltmeter that all capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN .
NOTICE
Equipment Damage!
Exceeding the recommended airflow can result in
damage to equipment. Trane is not responsible for
equipment damage resulting from exceeding
recommendations.
