Operation Manual
• Do not start or stop operating the ERV unit with the
power supply breaker turned ON or OFF.
Otherwise, fire or water leakage may result.
Furthermore, the fan will rotate abruptly if power failure
compensation is enabled, which may result in injury.
• Do not change operations roughly. It can result not only
in malfunction but also failure of switches or relays in
the unit.
• Turn off the power supply when the unit is not to be used
for long period of time.
Otherwise, the unit may get hot or catch on fire due to
dust accumulation.
• Do not block air inlets or outlets.
If the fan does not blow air throughout the entire room, it
may cause oxygen deficiency leading to bad health con-
dition or long-term health problems.
• Locate the outdoor air intake vent so that it does not take
in exhaust air which contains combustion air, etc.
Incorrect installation may cause a loss of oxygen in the
room, leading to serious accidents.
• Install the two outdoor ducts with down slope to prevent
rainwater from entering the unit.
If this is not done completely, water may enter the building,
damaging furniture, and cause electric shock and fire.
• Use electric insulation between the duct and the wall
when using metal ducts to pass metal or wire laths or
metal plating into wooden buildings.
This may cause electric shock short circuits or fire.
CAUTION
• Do not use the unit for any other purposes other than
ventilation. Do not use the unit for cooling precision
instruments, food, plants, animals or works of art.
• Before cleaning, stop the operation of the unit by turning
the power off or by pulling the supply cord out from its
receptacle. Otherwise, an electric shock and injury may
result.
• Do not wash the unit with excessive water. An electric
shock or fire may result.
• Avoid placing the controller in a spot splashed with
water. Water entering the controller may cause an elec-
tric shock or damage the internal electronic parts.
• Do not operate the unit when using a room-fumigation type
of insecticide. Failure to observe this could cause the
chemicals to be deposited in the unit and can endanger the
health of those who are hypersensitive to chemicals.
• The appliance is not intended for use by young children
or infirm persons without supervision.
• The remote controller should be kept away from children
so they cannot play with it.
• Consult with the installation contractor for cleaning.
• Incorrect cleaning of the inside of the unit could make
the plastics parts break and cause water leakage or elec-
tric shock.
• It is not good for your health to expose your body to the
air flow for a long time.
• Do not allow exhaust air to enter the outdoor air intake vent.
This may cause the interior of the room to become con-
taminated and harming the health.

NOTE
• Never press the button of the remote controller with a hard,
pointed object. The remote controller may be damaged.
• Never pull or twist the electric wire of the remote control-
ler. It may cause the unit to malfunction.
• Do not place appliances that produce open flames in
places that are exposed to the air flow of the unit or
under the unit. It may cause incomplete combustion or
deformation of the unit due to the heat.
• Do not expose the controller to direct sunlight. The LCD
display can become discolored and may fail to display
the data.
• Do not wipe the controller operation panel with benzene,
thinner, chemical dust cloth, etc. The panel may get discol-
ored or the coating can peel off. If it is heavily dirty, soak a
cloth in water-diluted neutral detergent, squeeze it well and
wipe the panel clean. Then wipe it with another dry cloth.
• Dismantling of the unit and additional parts should be
done in accordance with the relevant local, state and
national regulations.
• Do not use the unit or an air suction/discharge grille in
the following places.
a. Places with a mist of mineral oil, such as cutting oil.
b. Locations such as coastal areas where there is a lot of
salt in the air.
c. Locations such as hot springs where there is a lot of
sulfur in the air.
d. Locations such as factories where the power voltage
varies a lot.
e. In cars, boats, and other vehicles.
f. Locations such as kitchens where oil may splatter or
where there is steam in the air.
g. Locations where equipment produces electromag-
netic waves.
h. Places with an acid or alkaline mist.
i. Places where fallen leaves can accumulate or where
weeds can grow.
j. Place subjected to much carbon black.
Carbon black attaches to air filter and heat exchanger
core, making them unable to use.
• Take snow protection measures. Contact your dealer for
the details of snow protection measures, such as the
use of a snow protection hood.
• Do not attempt to do electrical work or grounding work
unless you are licensed to do so. Consult with your
dealer for electrical work and grounding work.
• Consult your dealer if the unit in operation generates
unusual noise.
• Always use the air filter.
If the air filter is not used, heat exchanger core will be clogged,
possibly causing poor performance and subsequent failure.
• Do not operate the ERV unit in Bypass mode when the
room air is under heating in winter or when the outdoor
temperature is 86°F or higher.
This may cause condensation to form on the main unit or
on discharge grille or around air supply opening.
• Insulate the two outdoor ducts to prevent dew conden-
sation (and the indoor duct as well if needed).
If this is not done completely, water may enter the build-
ing, damaging furniture, etc.
