GENERAL
Energy Recovery Module shall be as manufactured by Greenheck or approved equal, provided all specifications are met. Greenheck Model ERM equipment is used as the basis of design. Units shall be listed per ANSI/UL 1995, Heating and Cooling Equipment. Energy transfer ratings of the energy recovery wheel shall be ARI Certified. 

CASING AND ACCESS
Unit shall be constructed of G90 galvanized steel. All components shall be easily accessible through removable access panels for models ERM-36 and -52. Access to the energy wheel shall be through the ductwork and will require tools for models ERM-58, -64, and -74. Housing shall be insulated with 1-inch insulation. Duct adapters shall be factory installed on all four intake/discharge ports.

ENERGY RECOVERY WHEEL
Energy wheel shall be of total enthalpy, rotary air-to-air type, and shall be an element of a removable energy wheel cassette. The cassette shall consist of a galvanized steel framework (designed to produce laminar air flow through the wheel), an energy wheel as specified and a motor and drive assembly. The cassette shall incorporate a pre-tensioned drive belt. Note: Various energy wheel manufacturers are known to build non-segmented wheels. Segmented wheels are known to provide substantial time and labor-saving benefits over the entire life of the energy wheel. The wheel media shall be a polymer film matrix in a stainless-steel framework and be comprised of individual segments that are removable for servicing. Non-segmented energy wheels are not acceptable. Silica gel desiccant shall be permanently bonded to the polymer film and shall be designed and constructed to permit cleaning and servicing. The energy wheel is to have a five-year warranty. Performance criteria are to be as specified in AHRI Standard 1060, complying with the Combined Efficiency data in the submittal.

Silica gel desiccant shall be permanently bonded to wheel media to retain latent heat recovery after cleaning. Wheels with sprayed on desiccant coatings are not acceptable. Wheels with desiccant applied after wheel formation is not acceptable. Energy recovery device shall transfer moisture entirely in the vapor phase.

ELECTRICAL
All internal electrical components shall be factory wired for single point power connection. All electrical components shall be UL listed, approved, or classified where applicable and wired in accordance with the National Electrical Code.

WARRANTY
The energy recovery ventilator shall be warranted to be free from defects in material and workmanship for a period of one year from the shipment date. The energy recovery wheel shall be warranted to be free from defects in material and workmanship for a period of five years from the shipment date. Motors shall be warranted by the motor manufacturer for a period of one year from the shipment date.
