GENERAL SAFETY INFORMATION
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.
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.
Install the unit in the area where air temperature is above 50 °F (10 °C) to avoid
condensation in unit.
CAUTION
For general ventilating use only. Do not use to exhaust hazardous or explosive materials
and vapors.
Do not kink the power cord.
Do not install the unit in the area where the air stream temperature may exceed 104 °F
(40 °C).
The unit must be installed in a mechanical room, basement, or other conditioned space.
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.
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.
Protect the power cord from sharp edges, oil, grease, hot surfaces, chemicals or other
objects.
These fans are intended for residential use only.
When the product is to no longer be used, it must not be left in place but removed,
to prevent it from possibly falling.
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.

DESCRIPTION
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.

- Partially dedicated ducted 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.
Note
(1)The ERV unit must be balanced.
(2)It is mandatory that HVAC/AHU signal cord be
connected.

START-UP PROCEDURE
Fill in beginning time on the OA filter before
1
starting up the unit.
Connect the power then turn on the main switch on ERV.
2
If the ERV does not run, please check the wiring.
Check static pressure.
3
Using a manometer, measure the differential pressure of fresh air and exhaust air
respectively, then adjust the dampers for balancing airflows to make the test value
reach the differential pressure of setting volume as shown below.
Install the plug covers back when the check is complete.

OPERATION
<Control panel>
1
Main switch: Power on or off for ERV. Push the main switch
completely to the on/off position when turning on/off.
Note
The unit will consume some electricity unless you turn off the main switch.
2
ASHRAE time knob: The operation state will be changed with this knob. It is in units of
1 hour, for example: set to “10”, 10 minutes (ON) 50 minutes (OFF) 10 minutes (ON)...
cycle operation. The factory default is 60 Min/H.
3
SA knob: Set the supply air volume with this knob.
The factory default is 100 CFM.
4
EA knob: Set the exhaust air volume with this knob.
The factory default is 100 CFM.
Note
The SA air volume is limited less than “EA air volume + 20 CFM” when the outdoor
temperature is -22 °F (-30 °C)~14 °F (-10 °C). For example, when the EA air volume
setting is 50 CFM and the SA air volume setting is 100 CFM, actually the EA air volume
will be 50 CFM and the SA air volume will be 70 CFM.

Filter indicator:
The indicator will be on when the product accumulated run
time reaches to 90 days. The buzzing will sound every hour
and 10 seconds in a hour.
Note
If you want to turn off the the indication of buzzer, please
press filter reset button about 3 seconds until there is the
sound of a long beep. Press filter reset button about 3
seconds again until there is sound of two quick beeps, the
buzzer indication will be turned on again.
6
Running indicator: When the indicator is on, indicates the
product is running.
Filter reset button: Press the button after filter maintenance
For example: when main switch and wall switch are ON, suppose the customer to set as
ASHRAE:50 min/h, SA:90 CFM, EA:90 CFM,
when boost switch is ON, ERV enforces the instructions ASHRAE:60 min/h, SA:100 CFM,
EA:100 CFM;
when boost switch is OFF, ERV restores setting instructions of customer ASHRAE:50 min/h,
SA:90 CFM, EA:90 CFM;
Note
It’s better that the product is operated for 24 hours in order to prevent from being frozen.

For FV-10VEC2 and FV-10VEC2H
To ensure quiet operation of the ENERGY STAR certified H/ERV, each product model must be installed
using sound attenuation techniques appropriate for the installation.
The way your heat/energy-recovery ventilator is installed can make a significant difference to the
electrical energy you use. To minimize the electricity use of the heat/energy-recovery ventilator,
a stand-alone fully ducted installation is recommended. If you choose a simplified installation that
operates your furnace air handler for room-to-room ventilation, an electrically efficient furnace that has
an electronically commutated (EC) variable speed blower motor will minimize your electrical energy
consumption and operating cost.
Installation of a user-accessible control with your product model will improve comfort and may
significantly reduce the product model’s energy use.
