GENERAL DESCRIPTION
The energy recovery ventilator was designed to provide
energy efficient, cost effective ventilation to meet IAQ
(Indoor Air Quality) requirements while still maintaining
good indoor comfort and humidity control for a variety
of applications such as schools, classrooms, lounges,
conference rooms, beauty salons and others. It provides
a constant supply of fresh air for control of airborne
pollutants including CO
, smoke, radon, formaldehyde,
2
excess moisture, virus and bacteria.
The ventilator incorporates patented rotary heat
exchanger technology to remove both heat and moisture.
It is designed as a single package which can be easily
factory or field installed for new installations or retrofit
to the new Bard W**A and W**H series wall-mounted
units. The package consists of a unique rotary energy
recovery cassette that can be easily removed for
cleaning or maintenance. The ERV-F*3 has two 13"
diameter heat transfer wheels whereas the ERV-F*2 has
one 13" diameter heat transfer wheel. The heat transfer
wheels use a permanently bonded dry desiccant
coating for total heat recovery.
Ventilation is accomplished with two blower/motor
assemblies each consisting of a drive motor and dual
blowers for maximum ventilation at low sound levels.
The intake and exhaust blowers can be operated at the
same speed (airflow rate) or different speeds to allow
flexibility in maintaining desired building pressurization
conditions. Factory shipped on medium intake and low
exhaust. See Figure 6 on page 12 to change speeds.

The rotating energy wheels provide the heat transfer
effectively during both summer and winter conditions.
Provide required ventilation to meet the requirements
of ASHRAE 62.1 standard.
NOTE: During operation below 5°F outdoor
temperature, freezing of moisture in the heat
transfer wheel can occur. Consult the factory if
this possibility exists.
GENERAL INFORMATION
The ventilator should only be installed by a trained
heating and air conditioning technician. These
instructions serve as a guide to the technician installing
the ventilator package. They are not intended as a step-
by-step procedure with which the mechanically inclined
owner can install the package.
The ventilator housing is shipped in one carton which
contains the following:
•
Energy recovery ventilator
•
Exhaust damper assembly
•
Service door
•
Rain hood and mist eliminator
•
Installation instructions
UNPACKING
Upon receipt of the equipment, be sure to compare the
model number found on the shipping label with the
accessory identification information on the ordering and
shipping document to verify that the correct accessory
has been shipped.
Inspect the carton housing of each ventilator as it is
received and, before signing the freight bill, verify that
all items have been received and that there is no visible
damage. Note any shortages or damage on all copies
of the freight bill. The receiving party must contact
the last carrier immediately, preferably in writing,
requesting inspection by the carrier's agent. Concealed
damage not discovered until after loading must be
reported to the carrier within 15 days of its receipt.
