Only trained and qualified service personnel shouldinstall, repair, or service air-conditioning equipment. Untrained personnel can perform the basic maintenancefunctions of cleaning coils and filters and replacing filters. Allother operations should be performed by trained servicepersonnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached tothe unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and workgloves. These instructions describe how to install, start up, andservice 62E energy recovery ventilator (ERV) units. WARNING Electrical shock can cause personal injury and death. Shutoff all power to this equipment during installation. Theremay be more than one disconnect switch. Tag all disconnect locations to alert others not to restore power until workis completed. GENERAL The 62E ERV units recover energy from building exhaustair and pre-condition ventilation air. See Tables 1A-2B for unitdata. All 62EB-62EU units are configured for vertical discharge (through the bottom). Vertical units may be installed on: • a stand-alone roof curb • a combination curb for direct coupled connection to arooftop unit If horizontal supply and return is desired using a verticalunit, the vertical unit may be installed on a horizontal supply/ return base.
