SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo- nents. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform the basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves. These instructions describe how to install, start up, and service 62E energy recovery ventilator (ERV) units.

WARNING

Electrical shock can cause personal injury and death. Shut off all power to this equipment during installation. There may be more than one disconnect switch. Tag all discon- nect locations to alert others not to restore power until work is completed.

GENERAL

The 62E ERV units recover energy from building exhaust air and pre-condition ventilation air. See Tables 1A-2B for unit data. All 62EB-62EU units are configured for vertical dis- charge (through the bottom). Vertical units may be installed on:

a stand-alone roof curb

a combination curb for direct coupled connection to a rooftop unit

If horizontal supply and return is desired using a vertical unit, the vertical unit may be installed on a horizontal supply/ return base.

NOTE: The horizontal supply/return base accessory includes a roof curb. The horizontal supply/return base should NOT be used with a stand-alone roof curb.

All 62E2-62E7 units are configured for horizontal discharge (through the side). Horizontal units may be installed on a stand-alone roof curb.

DIRECT COUPLED APPLICATIONS (Vertical) — The ERV unit can be installed directly coupled to a RTU (rooftop unit). For vertical (through the roof) applications, the connec- tion between the 62EB-62EU ERV unit and the RTU may be
