WARNING (During Operation)
• When the unit is in abnormal conditions (smell of some-
thing burning, etc.), cut off the power, and contact your
dealer.
Continued operation under such circumstances may result
in a failure, electric shock, and fire.
• It is not good for your health to expose your body to the
air flow for a long time.
• Do not operate the unit with a wet hand.
An electric shock may result.
• Open the windows and ventilate the room if flammable
gas is leaked.
Insufficient ventilation when the unit is turned on or off may
cause an explosion from sparks at the electrical connection.
• Do not wash the HRV unit with water.
Electric shock or fire may result. (Not including air filters, etc.)
• Be sure to stop the unit and turn off the power when
cleaning or inspecting it.
As the fan is rotating at high speed, it will cause injury.

CAUTION (During Operation)
• Do not use the HRV unit for other purposes.
In order to avoid any quality deterioration, do not use the
unit for cooling precision instruments, food, plants, animals
or works of art.
• Do not use burning appliances directly in the path of the
air from the unit.
Incomplete combustion of the burning appliances may occur.
• Never expose little children, plants or animals directly
to the air flow.
Adverse influence to little children, animals and plants may
result.
• Neither place a flammable spray bottle near the HRV unit
or indoor intake and outlet grills nor perform spraying.
Doing so may result in a fire.
• Turn off the power when the unit is not to be used for
long periods of time.
Otherwise, the unit may get hot or catch on fire due to dust
accumulation.
• Do not block the intake or outlet grills.
If the fan does not blow air throughout the entire room it may
cause machine trouble.
• Use gloves when cleaning.
Cleaning without gloves may cause injury.
• Do not operate the remote controller with wet hands.
This may cause electric shock.
• Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are danger-
ous to touch, and a machine trouble may happen. For check-
ing and adjusting the internal parts, contact your dealer.
• Do not let any kind of sprays get on the remote control-
ler (insecticides, cleaning materials, etc.)
This may cause breakage, deformation, or malfunction.
• Do not wipe the controller operation panel with benzine,
thinner, chemical dustcloth, etc.
The panel may get discolored or the coating peeled off. If it
is heavily dirty, soak a cloth in water-diluted neutral deter-
gent, squeeze it well and wipe the panel clean. And wipe it
with another dry cloth.
• The appliance is not intended for use by young children
or infirm persons without supervision.
• Young children should be supervised to ensure that
they do not play with the appliance.
• Consult with installation contractor for cleaning the
inside of the air conditioner.
Wrong cleaning may make the plastics parts broken or
cause failure of water leakage or electric shock.
• Do not place objects in direct proximity of the outdoor
unit and do not let leaves and other debris accumulate
around the unit.
Leaves are a hotbed for small animals which can enter the
unit. Once in the unit, such animals can cause malfunctions,
smoke or fire when making contact with electrical parts.
WARNING (For installation)
• Do not attempt to install the unit yourself.
Ask your dealer for installation of the unit.
Incomplete installation performed by yourself may result in a
water leakage, electric shock, and fire.
• Installation should be done following the installation
manual.
Incorrect installation may cause leaking, electric shock, or
fire. Injuries may result if the unit falls.
• Do not allow exhaust air to enter the outside air intake
vent.
This may cause the interior of the room to become contami-
nated and harming the health.
• Locate the outside 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.
