On the pulley side of the cassette, remove the four (4) fasteners that hold the bearing support channel in place. Once the bearing support is removed the wheel can be pulled from the cassette. To replace the wheel, reverse this procedure. Removing the Energy Recovery Wheel Segments ERV-361, 521, 581, 522 and 582 (stainless steel rim) Steel retainers are located on the inside of the wheel rim. Push the retainer towards the center of the wheel, then lift up and away to release segments. Wheel segment removed Bracket Segment Retainer Lift away from segment Catch Segment Retainer Push toward center Center of Wheel Spoke Inside of wheel rim Important! Place retainers back in the original position before rotating the energy recovery wheel, otherwise damage to retainer will occur. 28 Energy Recovery Ventilator Cleaning the Energy Recovery Wheel If the wheel appears excessively dirty, it should be cleaned to ensure maximum operating efficiency. Only excessive buildup of foreign material needs to be removed. Discoloration and staining of energy recovery wheel does not affect its performance. Thoroughly spray wheel matrix with household cleaner such as Fantastik® or equivalent. Gently rinse with warm water and using a soft brush remove any heavier accumulation. A detergent/water solution can also be used. Avoid aggressive organic solvents, such as acetone. The energy recovery wheel segments can be soaked in the above solution overnight for stubborn dirt or accumulation. After cleaning is complete, shake the excess water from the wheel or segments. Dry wheel or segments before placing them back into the cassette. Place wheel or segments back into cassette by reversing removal procedures. CAUTION Do not clean energy recovery wheel segments with water in excess of 140.F (60.C). Do not dry energy recovery wheel segments in air in excess of 140.F (60.C). The use of a pressure washer to clean segments is not recommended. Damage could result. Energy Recovery Wheel Belt Inspect belts each time filters are replaced. Belts that look chewed up or are leaving belt dust near the motor pulley may indicate a problem with the wheel. Be sure to inspect wheel for smooth and unrestricted rotation. If a belt requires replacement, contact the local Greenheck representative. Instructions for replacement will ship with the new belt. Energy Recovery Wheel Bearing In the unlikely event that a wheel bearing fails, the bearing is behind a removable plate on the wheel support beam which is accessible through the outdoor air filter door (and exhaust filter door on the ERV522 and 582). Contact the local Greenheck representative for detailed instructions on how to replace the bearing.

The ERV is normally slaved (24 volt) to the roof top air handler. When the roof top air handler starts, the auxiliary contactor in the air handler closes to start the ERV. Summer Operation Outdoor air is preconditioned (temperature and moisture levels are decreased) by the transfer of energy from the cooler, drier, exhaust air via the energy recovery wheel. The preconditioned air is typically mixed with return air going ...
