• Do not use the unit without air filter.
The quality of heat exchange element may get
worse by dust, and it may cause malfunction.
• Do not put containers with water such as vases
and flowerpots on the Heat Reclaim Ventilator
unit.
It may cause electric shock or fire because water
goes into the unit.
• Make sure your scaffolding hold when working
at heights.
If the scaffolding is unstable, it may cause to fall
and injury.
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
contaminated 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.
• All wiring must be performed by an authorized
electrician.
To do wiring, ask your dealer. Never do it yourself.
• Make sure that a separate power supply circuit
is provided for this unit and that all electrical
work is carried out by qualified personnel
according to local lows and regulations.
Insufficient power circuit capacity or incorrect work
may cause electric shock or fires.
• Install the unit on a foundation strong enough
to withstand the weight of the unit.
A foundation of in sufficient strongth may result in
the unit falling and causing injuries.
• Connect the remote controller to the correct
model.
This may cause electric shock or fire.
• Do not connect additional electric wirings.
This may cause fire.
• Do not install the Heat Reclaim Ventilator unit at
any place where flammable gas may leak out.
If the gas leaks out and stays around the unit, a fire
may break out.
• Be sure to establish an earth.
Do not earth the unit to a utility pipe, arrester, or
telephone earth.
Incomplete earth may cause electrical shock, or
fire.
A high surge current from lightning or other sources
may cause damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may
result in electric shocks, or fire.
b. Place such as kitchens or other places where
oil fumes are present.
This may cause fire.
c. Place such as machinery plant and chemical
plant where gas, which contains noxius gas
or corrosive components of materials such
as acid, alkali, organic solvent and paint, is
generated.
Place where combustible gas leakage is
likely.
This may cause gas poisoning or fires.
d. Place such as bathroom subjected to
moisture.
Electric leak or electric shock and other failure
can be caused.
e. Locations below freezing point.
f. Near machinery emitting electromagnetic
waves.
Electromagnetic waves may disturb the operation
of the control system and result in a malfunction
of the equipment.
g. Place subjected to much carbon black.
Carbon black attaches to air filter and heat
exchange element, marking them unable to use.
• Is a snow protection measure taken?
For detail, consult your dealer.
• Make sure the temperature and the humidity
of the installation location is within the usage
range, not exceed the limit.
Do not install in cold storage or other locations with
low temperatures or near heated pools. This may
cause fires or short circuits.
• 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.
• Insulate the two outdoor ducts to prevent dew
condensation (and the indoor duct as well if
needed).
If this is not done completely, water may enter the
building, damaging furniture, etc.
CAUTION (For Installation)
• Do not use the Heat Reclaim Ventilator unit or
an air suction/discharge grille in the following
places.
a. Place subjected to high temperature or direct
flame.
Avoid a place where the temperature near the
Heat Reclaim Ventilator unit and the air suction/
discharge air grille exceeds 40°C. If the unit is
used at high temperature, deformed air filter and
heat exchange element or burned motor result.
