Cleaning the Energy Recovery Wheel

Wheel Belt & Pulley

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 140ºF (60ºC).

Do not dry energy recovery wheel segments in air in excess of 140ºF (60ºC).

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 ERV- 522 and 582). Contact the local Greenheck

representative for detailed Wheel Bearing instructions on how to

replace the bearing.
