There are two kinds of safety cautions and tips listed here as fol-
lows:
WARNING

serious consequences as death or
severe injury.
CAUTION
................ Improper handling can lead to injury or
damage. It could also have serious
consequences under certain condi-
tions.
NOTE
• These instructions will ensure proper use of the equipment.
Be sure to follow these important safety cautions.
Keep these warning sheets handy so that you can refer to
them if needed.

to hand over this user’s manual to the new user.
WARNING (During Operation)
• Never inspect or service the unit by yourself.
Ask a qualified service person to perform this work. (The
qualified service person)
• In order to avoid electric shock, fire or injury, or if you
detect any abnormality such as smell of fire, turn off
power and call your dealer for instructions.
• 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.
• Keep all flames away if the refrigerant leaks.
The refrigerant in the air conditioner is safe and normally
does not leak. If the refrigerant leaks inside the room, the
contact with a fire of a burner, a heater or a cooker may
result in a harmful gas. Extinguish all flames from burning
appliances (such as stoves, heaters, etc.) ventilate the
room, and contact your dealer. Do not use the air condi-
tioner until when a service person confirms to finish repair-
ing the portion where the refrigerant leaks.
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 spray-
ing.
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.
• Always use the air filter.
If the air filter is not used, heat exchange elements will be
clogged, possibly causing poor performance and subse-
quent failure.
• Use gloves when cleaning.
Cleaning without gloves may cause injury.
• Do not use benzene or thinner to clean the outside sur-
faces of the air conditioner.
This may cause cracks, discoloration, or machine trouble.
• Do not operate the HRV unit in Bypass mode when the
room air is under heating in winter or when the outside
temperature is 30°C or higher.
This may cause condensation to form on the main unit or on
discharge grill, or around air supply opening.
• 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 dan-
gerous to touch, and a machine trouble may happen. For
checking and adjusting the internal parts, contact your
dealer.
• Do not change operations suddenly.
It can result not only in malfunction but also failure of
switches or relays in the remote controller.
