1 SAFETY PRECAUTIONS
Be sure to follow this “SAFETY PRECAUTIONS”. This product comes
under the term “appliances not accessible to the general public”.
This manual classifies the precautions into WARNINGS and CAU-
TIONS. Be sure to follow all the precautions below: They are all
important for ensuring safety.
WARNING ..............Indicates a potentially hazardous situ-
ation which, if not avoided, could result
in death or serious injury.
CAUTION ...............Indicates a potentially hazardous situa-
tion which, if not avoided, may result in
minor or moderate injury. It may also be
used to alert against unsafe practices.
• After the installation is completed, test the Heat Reclaim Ventila-
tor unit and check if the Heat Reclaim Ventilator unit operates
properly. Give the user adequate instructions concerning the use
and cleaning of the Heat Reclaim Ventilator unit according to the
Operation Manual. Ask the user to keep this manual and the
Operation Manual together in a handy place for future reference.
WARNING
• Ask your local dealer or qualified personnel to carry out
installation work. Improper installation may result in water
leakage, electric shocks or a fire.
• Installation should be done following the installation manual and
no changes should be made to the unit.
Improper installation may result in water leakage, electric shocks
or a fire. Injuries may result if the Heat Reclaim Ventilator unit falls.
• Install the Heat Reclaim Ventilator unit on a foundation that can
withstand its mass.
Insufficient strength may result in the Heat Reclaim Ventilator
unit falling down and causing injury. In addition, it may lead to
vibration of indoor units and cause unpleasant chattering noise.
• Do not allow exhaust air to enter the outside air intake vent.
This may cause the air of the room to become contaminated,
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.
• Make certain that all electrical work is carried out by qualified
personnel according to the applicable legislation (note 1) and
this installation manual, using a separate circuit.
In addition, even if the wiring is short, make sure to use a wir-
ing that has sufficient length and never connect additional
wiring to make the length sufficient. Insufficient capacity of
the power supply circuit or improper electrical construction
may lead to electric shocks or a fire.
(note 1)
applicable legislation means “All international,
national and local directives, laws, regulations and/
or codes which are relevant and applicable for a
certain product or domain”.
• Be sure to use only the specified parts and accessories for
installation work. Failure to use the specified parts may result
in the Heat Reclaim Ventilator unit falling down, water leak-
age, electric shocks, a fire, etc.
• Carry out the specified installation work in consideration of strong
winds, typhoons, or earthquakes. Improper installation may result
in an accident such as Heat Reclaim Ventilator unit falling.
• Make sure that all wiring is secure, using the specified wiring and ensur-
ing that external forces do not act on the terminal connections or wiring.
Incomplete connection or fixing may cause an overheat or a fire.
• When wiring remote controller wiring and transmission wir-
ing, and wiring the power supply, form the wiring orderly so
that the control box lid can be securely fastened. If the control
box lid is not in place, overheat of the terminals, electric
shocks or a fire may be caused.
• Consult your local dealer regarding what to do in case of
refrigerant leakage.
When the Heat Reclaim Ventilator unit is installed in a small
room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the con-
centration limit in the event of a leakage. Otherwise, this may
lead to an accident due to oxygen deficiency.
• If refrigerant gas leaks during installation work, ventilate the
area immediately. Toxic gas may be produced if refrigerant
gas comes into contact with a fire.
• After completing the installation work, check to make sure that
there is no leakage of refrigerant gas. Toxic gas may be pro-
duced if refrigerant gas leaks into the room and comes into con-
tact with a source of a fire, such as a fan heater, stove or cooker.
• Disconnect the power supply before touching the electric compo-
nents. If you touch the live part, you may get an electric shocks.
• Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
• Earth the Heat Reclaim Ventilator unit.
Do not connect the earth wiring to gas or water piping, lightning
conductor or telephone earth wiring. Incomplete earthing may
cause electric shocks or a fire. A high surge current from light-
ning or other sources may cause damage to the air conditioner.
• Be sure to install an earth leakage circuit breaker.
Failure to do so may cause electric shocks and a fire.
CAUTION
• Install drain piping according to this installation manual to
ensure good drainage, and insulate the piping to prevent
condensation. Improper drain piping may cause water leak-
age, make the furniture get wet.
• Install the Heat Reclaim Ventilator unit, power supply wiring,
remote controller wiring and transmission wiring at least 1
meter away from televisions or radios to prevent image inter-
ference or noise. (Depending on the radio waves, a distance
of 1 meter may not be sufficient to eliminate the noise.)
• Install the two outdoor ducts with down slope to prevent rain-
water from entering the unit. If this is not done completely,
water may enter the building, may damage furniture, and
cause electric shocks and fire.
• Insulate the two outdoor ducts and the supply air duct to pre-
vent condensation. If this is not done completely, water may
enter the building, may damage furniture, etc.
• Insulate the duct and the wall electrically when a metal duct
is to be penetrated through the metal lattice and wire lattice
or metal lining of a wooden structure wall. Improper duct
work may cause electric shocks or fire.
