Warning, Caution and Important notes appear through-
out this manual in specific and appropriate locations to
alert Installing Contractors and maintenance or service
personnel of potential safety hazards, possible equipment
damage or to alert personnel of special procedures or in-
structions that must be followed as outlined below.
Hazards may exist within this equipment because it con-
tains electrical and powerful moving components. Only
qualified service personnel should install or service this
equipment. Untrained personnel can perform basic main-
tenance such as maintaining filters. Observe precautions
marked in literature and on labels attached to the unit.
Follow all safety codes.
The ERV500i ventilator is intended for installation within
a suspended ceiling space or mechanical room. The
ERV500e ventilator is intended for installation on a rooftop
with a factory supplied or field supplied roofcurb.
These ventilators provide 100% outdoor air ventilation
and provide energy recovery between the exhaust and
supply airstreams. The Energy Recovery Ventilators (ERVs)
use an enthalpy wheel for total energy recovery which
provides superior efficiency in hot and humid climates. In
addition, they provide excellent heat recovery in winter
and transfer moisture from exhausted air to the outdoor
air before supplying it to an occupied space.
Move the unit to its installation location and remove pack-
aging. See Appendix F for unit weight and specifications.
Inspect the exterior and interior of the equipment for dam-
age. Ensure there is no damage to internal components
such as fans, motors, dampers, enthalpy wheel, insulation,
etc. File a claim with the shipping company if the unit is
damaged.
System Requirements
Consult local building codes and the National Electrical
Code for special installation requirements. Note additional
requirements below and in the Start-up section.
Interior Mount
The unit should be installed to allow easy access for main-
tenance. Appendix B shows minimum clearance required
between front access and any obstruction to allow for
removal of components (fans, filters, enthalpy wheel). The
front of the unit is defined in relation to the inlet ports
and outlet ports on the unit. Port location and overall di-
mensions are shown in Appendix B. Unit components are
shown in Appendix E.
