GENERAL SAFETY INFORMATION

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.

Excessive bending Successive bending Squeezed duct Bend close to duct adapter

Disconnect power by switching off wall switch first, then main switch and unplug

before working on unit when replacing the jumper cable with wall switch.

Install the unit in the area where air temperature is above 50 °F (10 °C) to avoid

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.

(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.

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.
