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.
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.
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) -
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

    (62EB-EU and 62E2-E7 Units) — zontal transition accessory is used to connect the ERV to the horizontal return of a Carrier rooftop unit. To provide horizon- tal exhaust and ventilation air connections on 62EB-EU units, the horizontal base accessory must also be installed. The acces- sory is not needed on 62E2-E7 units.
