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.

product 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
condensation in unit.
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.

GENERAL SAFETY INFORMATION
NOTICE

The Panasonic Energy Recovery Ventilator (ERV) uses 2 blower fans driven by 2 DC motors.
The motor is designed to have an extended service life with reduced energy consumption.
It also incorporates a thermal-cutoff for safety.
The exhaust air (EA) duct includes an electric damper to prevent backdrafting. The outside
air (OA) duct includes an electric damper to prevent backdrafting.
Energy Recovery Introduction: Compared to an HRV (Heat Recovery Ventilator), the ERV can
also transfer humidity and recover energy from that humidity. The ERV can exchange energy
between the stale EA and the “fresh” OA, transferring heat and moisture into the incoming
cold air in a heating climate and pre-cooling and reducing the humidity of the incoming hot
air in a cooling climate. This tempering and treatment of the required ventilation air helps
maintain a fresh environment even when the heating or cooling system is not operating.

WIRING DIAGRAM
(1)The HVAC/AHU signal cord, wall switch cord, boost switch cord, wall switch and
boost switch are not supplied.
Note
WIRING METHOD
Jumper cable
(2)The terminal of wall switch has been connected by jumper cable for factory default.
(3) If a wall switch is not used to power down the ERV note that cutting power by
unplugging the unit, and/or opening the frame cover to maintenance, will disallow
the unit to run a power down process; leaving the dampers in the open position.
This could increase the risk of cold air infiltration which may lead to frost forming in
the ERV.
(4) If you do not intend to run the product for more than 24 hours we recommend you
connect product with a wall switch to control the standby and running of the product.

WIRING METHOD

maintenance plate and wiring cover. (Fig.1)
4.Insert wires into the corresponding terminals deeply through the ribs. (Fig.1)
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.
If you are not connecting to the HVAC/AHU,
please open knock-out hole for wall switch
cord/boost switch cord connection only. (Fig.1)
Note
CAUTION
The capacity of wall switch, boost switch
should be more than 120 V~3 A to control

Method -Simplified ducted installation (Return method)
Note
DUCTWORK
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.
(Fig.7 & Fig.8)
(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. Fig.7

INSTALLATION (WALL MOUNT)

DUCTWORK
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. (Fig.9 & Fig.10)
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.
Method -Partially dedicated ducted installation
Note
(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 feet of straight duct run from all duct attachment points on the
ERV. Do not use any elbows or other peripheral pieces inside of 2-3 feet when
attaching duct runs to the ERV.
(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.12.
(6)The airflow must be confirmed on site using the balancing procedures found in
P.14. Fig.8

START-UP PROCEDURE
2.Connect the power cord to power then turn on the main switch on ERV for start-up.
If the ERV does not run, please check the wiring connections.
1.Fill in beginning time on the OA filter before starting up the unit.
The method of remove and install OA filter please refer to P.17~P.18 (Fig.20~22)
and P.18 (Fig.24~25).
3.Remove plug covers in plugs on frame cover and check static pressure.
Using a magnehelic gauge, 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.
<Control panel>
EA knob: Set the exhaust air volume with this knob.
The factory default is 100 CFM.
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.
Main switch: Power on or off for ERV. Push the main switch
completely to the on/off position when turning on/off.

SA knob: Set the supply air volume with this knob.
The factory default is 100 CFM.
The unit will consume some electricity unless you turn off the main switch.
OPERATION
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.

It’s better that the product is operated for 24 hours in order to prevent from being frozen.
OPERATION
(1) The indicator will be on when the product accumulated
running time reaches to 90 days. The buzzing will sound
every hour and 10 seconds in a hour.
(2)If you want to turn off 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.
Note

Filter indicator: The indicator will light on when the accumulated
running time is up to 3 months. When the indicator is on (with
buzzer sound), indicates need to maintain RA filter and OA filter.

unplug the product before working on unit when it is in default mode.
CAUTION
1.Open the frame cover by unlocking the
latches. (Fig.20)
Routine maintenance must be performed
every 2 or 3 months, clogged filters may
cause condensation on the unit due to air
flow reduction.
Never use petrol, benzene, thinner or any
other such chemicals to clean the ERV.
Do not allow water to enter ERV.
Do not immerse resin parts in water over
60 °C.
Please wear gloves to avoid pinching
fingers during maintenance.
(1)If not convenient for maintenance, can
also rotate the lock plate at the hinge and
remove the frame cover. (Fig.21)
(2)There is a spring on the inside of frame
cover, please do not damage or deform
it, otherwise, the ERV may not operate.
