NOTICE
Ceiling joist and wall stud must be subjected to static load more than five times the
weight of the product.
The special-purpose or dedicated parts, such as mounting fixtures, must be used if such
parts are provided.
Do not kink the power cord.
The OA duct and EA duct must be connected directly to the outside.
Make certain that the electric service supply voltage is AC 120 V, 60 Hz.
These fans are intended for residential use only.
Do not install the unit where ducts are configured as shown below.
Adapter
Protect the power cord from sharp edges, oil, grease, hot surfaces, chemicals or other
objects.
When the product is to no longer be used, it must not be left in place but removed,
to prevent it from possibly falling.
Follow all local electrical and safety codes, as well as the National Electrical Code (NEC)
and the Occupational Safety and Health Act (OSHA).
Always disconnect the power source before working on or near the fan, motor, fixture
or wiring cover.
For general ventilating use only. Do not use to exhaust hazardous or explosive materials
and vapors.
Sufficient air is needed for proper combustion and exhausting of gases through the
flue (chimney) of fuel burning equipment to prevent backdrafting. Follow the heating
equipment manufacturer’s guideline and safety standards such as those published by
the National Fire Protection Association (NFPA), and the American Society for Heating
Refrigeration and Air Conditioning Engineers (ASHRAE) and the local code authorities.

GENERAL SAFETY INFORMATION
NOTICE
Energy Recovery Introduction: Compared to HRV (Heat Recovery Ventilator), ERV can also
transfer humidity and recover energy from that humidity. ERV can exchange energy
between “stale” EA and “fresh” OA, by transferring heat and moisture into the incoming cold
air, and pre-cooling and reducing the humidity of the incoming hot air. This helps maintain a
fresh environment even when the heating or cooling system is not operating.

(1)The terminal of wall switch has been connected by jumper cable as factory default.
If connecting with wall switch, please remove the jumper cable.
Note
(2)The HVAC/AHU signal cord is optional, please connect it when you want to control
the HVAC/AHU.
If connecting with HVAC/AHU, the HVAC/AHU will turn on while ERV turns on.
(3)If you are not connecting to the HVAC/AHU, please open knock-out holes for wall
switch and boost switch connection only.
(4)Insert wires into the corresponding terminals deeply through the ribs.
Make sure the screw of terminal securely fastens the copper wire and the copper
wire is not exposed.
(5)Reinstall the wiring cover and maintenance plate.

MethodⅠ- Simplified ducted installation (Return method)
Note
DUCT INSTALLATION
This method draws return air from the return air duct
of the air furnace and supplies an equal amount of
outside air farther downstream into the return duct.
(1)The ERV unit must be balanced.
(2)
It is mandatory that HVAC/AHU signal cord be connected.
(3)Check local codes and authority having
jurisdiction for acceptance.
Note
(1)Must Have 2-3 ft straight run on all duct attachments points
before elbow is more than 2 ft (610 mm).
(2)Unit is normally balanced on high speed with the furnace blower on.
(3)A minimum separation of 40 inches (1 m) is recommended between the two
direct connections.
(4)The exhaust air connection shall be upstream of the supply air connection to
prevent exhausting any fresh air.
(5)The distance between two outdoor hoods please see P.11.
(6)The airflow must be confirmed on site using the balancing procedures found in P.13.

DUCT INSTALLATION
This method draws return air from specific points in the house and supplies an equal
amount of outside air into the return air duct of the air furnace.
Return air ducts of ERV should be installed in areas of the home where the poorest indoor
air quality exists (bathroom and kitchen).
The air furnace blower should be running when the ERV is operating to evenly distribute the
outside air throughout the house.
