Stirling Technology, Inc. RecoupAerator SD-95+ ® Section 2: Installation Guide Instructions for Licensed Contractors Installation: Note: It is recommended that a licensed HVAC Technician install this product. There are numerous considerations that must be taken in to account when installing a ventilation system, including airflow dynamics and condensation issues.
Stirling Technology, Inc. Installation Dimensions: Allow clearance in marked areas for access to the unit for regular maintenance and servicing. Also, you must leave room on both ends (with collars) to connect ductwork to the unit.

Stirling Technology, Inc. Installation Options ® There are three basic ways to install the inside ducts for the RecoupAerator Option 1: Dedicated Ductwork This is the most complete installation option and is ideal for new construction. It should be used when the customer has a specific problem associated with indoor air quality. It is also the only option for homes without forced air heating systems.
Page 16
Stirling Technology, Inc. Option 2: Shared Ductwork Method 1. This method utilizes the existing home HVAC duct system completely. Both ® the stale air removal and the fresh air in ducts from your RecoupAerator will be attached to the cold air return duct of your HVAC system. Be sure to keep at least 3 feet of space along the cold air return line between the two ventilator lines (see diagram).
Stirling Technology, Inc. Method 3. This method partially utilizes the existing home HVAC duct system. The fresh ® air in duct from the RecoupAerator gets ducted into the cold air return line of the furnace. A minimum of 3 to 6 foot distance between this line and the furnace is recommended. The ®...

Stirling Technology, Inc. ® Horizontal: Use Ceiling Mounting Kit (CM-02) to suspend the RecoupAerator from the ‘D’ rings located on the four corners of the unit (SEE BELOW). The motor side of the unit should be facing the floor. Allow adequate space (12 inches) between the ceiling and the unit to allow for servicing of pulleys and belts.
Stirling Technology, Inc. ® Ducting: Ducting between the RecoupAerator and the outdoors (those collars marked CONNECT TO OUTSIDE) and all ducting in unconditioned spaces must be insulated. Use vapor barriers as needed to prevent condensation. Vapor barriers always go on the warm side of a duct.

Stirling Technology, Inc. To insure maximum airflow, use the largest practical duct for the installation. Under no circumstances should the trunk duct size be less than 6 inches, as this will restrict the airflow considerably. Insulated flex ducts tend to reduce blower noise levels but add airflow resistance, while galvanized ducts provide least resistance to air flow and are easiest to install properly.
Stirling Technology, Inc. 8. Final operational duct system to have less than 0.5” w.c. total external static pressure. CAUTION All ducting to the outdoors should be installed above anticipated snow and flood lines and fitted with screened weather caps to prevent bird and insect entry.
Stirling Technology, Inc. Installing the Inside Ducts Location of supply and exhaust vents inside the house is an important factor in ventilation. Consider the following guidelines for maximum effectiveness: 1. The air exhaust point should be located high in the room, as far as possible from the point of air entry.

Stirling Technology, Inc. is complete will yield inaccurate results. To balance the airflow, a manometer is needed (optional accessory). There are four balancing ports on top of the SD-95+ unit, one set beside each filter access door, marked IN and OUT. These ports should remain plugged except when balancing airflow.
Stirling Technology, Inc. The “check filter” indicator light is located on the front side of the controller and will light after a continuous operation of 90 days (24 hrs/day, 7 days a week approximately). Due to differences in indoor and outdoor environments, your filters may or may not be in need of cleaning at this interval.
