General Information Warnings and Cautions Notice that Warning and Caution appear at appropriate places in this manual. WARNING ...indicates a potentially hazardous situation that could result in death of serious injury. CAUTION ...alerts you to conditions that may result in minor or moderate injury or equipment damage. - Page 5 Two additional access doors are provided for service access into the outside/supply air section. The two access doors are accessible from the inside of the air handler. The energy wheel cassette is permanently installed in the section. In all but the 1500 CFM wheel size, the individual segments of the energy wheel are removable for cleaning or replacement.

Operation 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! Disconnect the electrical and remote disconnects before servicing. Do not open the service access doors while the unit is operating. - Page 15 the diameter seals away from the surface of the wheel. Apply power to confirm free wheel rotation. Re-adjust and tighten the seals according to instructions in the “Service and Repair” section on page 21. Figure 4. Segment retainers Figure 5. Belt tracking Damper Actuators (if so equipped): Stroke the actuators to observe full open and full closure of the dampers.

Page 16: Routine Maintenance
Wash the segments or the wheel in a five-percent solution of non-acid-base coil cleaner (part no. CHM00021 at your local Trane parts center) or in a alkaline detergent and warm water. Soak the segments in the solution until grease, oil, and tar deposits are loosened. - Page 17 WARNING Always keep hands away from the bearing support beam when installing or removing segments. Failure to do so could result in serious injury. High-maintenance applications may benefit from keeping a spare set of clean segments on hand. This allows for rapid change-out of clean segments with minimal downtime.

Page 19: Cleaning The Energy Wheel Motor
With the embedded stiffener facing the motor side, insert the nose of the segment between the hub plates. Holding the segment by the two outer corners, press the segment toward the center of the wheel and inward against the spoke flanges. If hand pressure does not fully seat the segment, insert the flat tip of a screwdriver between the wheel rim and the outer corners of the segment and apply gentle force while guiding the segment into place. -
Page 20: Bearing And Motor Lubrication
Filtration Debris screens are provided on the energy wheel section to prevent debris from entering the energy wheel section. Inspect these screens monthly and clean them as necessary. Bearing and Motor Lubrication The wheel drive motor and wheel support shaft bearings are permanently lubricated and no further lubrication is necessary. -

Page 23: Seal Adjustment
17 Re-install the diameter seals or hub seal and tighten the retaining screws. 18 Adjust the seals per the “Seal Adjustment” procedure. 19 Rotate the wheel in a clockwise direction to confirm that the wheel rotates freely with a slight drag on the seals. 20 Re-install the bearing locking collar. -
Page 24: Drive Motor And Pulley Replacement
Adjust the seals toward the wheel surface until slight friction on the paper feeler gauge is felt when the gauge is moved along the length of the spoke. Check the seal adjustment through a full rotation of the wheel. Retighten the adjusting screws and recheck the clearance with the paper feeler gauge. -
