SAFETY CONSIDERATIONS
Please read these “SAFETY CONSIDERATIONS” carefully
before installing HRV and be sure to install it correctly.
The safety precautions listed here are divided into two catego-
ries.
In either case, important safety information is listed which must
be read carefully.
WARNING
............. Failure to observe a warning may
result in death or serious injury.
CAUTION
............... Failure to observe a caution may result
in injury or damage to the equipment.
These too might lead to serious injury
depending on the circumstances.
After completing the installation, make sure that the unit oper-
ates properly during the start-up operation. Please instruct the
customer on how to operate the unit and keep it maintained.
Also, inform customers that they should store this installation
manual along with the operation manual for future reference.
WARNING
•
Ask your dealer or qualified personnel to carry out installation
work. Do not try to install the machine yourself.
Improper installation may result in water leakage, electric
shocks or fire.
•
Installation should be done following the installation manual
and no changes should be made to the unit.
Incorrect installation may cause leaking, electric shocks, or
fire. Injuries may result if the HRV falls.
•
Install the unit on a foundation strong enough to withstand
the weight of the unit.
A foundation of insufficient strength may result in the equip-
ment falling and causing injuries.
•
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 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 laws and regulations and this
installation manual.
An insufficient power supply capacity or improper electrical
construction may lead to electric shocks or fire.
Insufficient power supply capacity or incorrect wiring may
cause electrical shocks or fire.
•
Use only accessories and manufacturer-specified parts
when installing.
The use of parts other than specified may cause drop of the
unit, water leakage, electric shock, fire or other accidents.
•
Be sure to ground.
Do not connect the ground wire to gas or water pipes, light-
ning rod or a telephone ground wire.
Incomplete grounding may result in electric shocks.
•
Make sure that all wiring is secured, the specified wires are used,
and no external forces act on the terminal connections or wires.
Improper connections or installation may result in overheat-
ing or fire.
•
When wiring the power supply and connecting the remote
controller wiring and transmission wiring, position the wires
so that the electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in
electric shocks, fire or the terminals overheating.
•
When installing the unit in a small room, take measures
against to keep refrigerant concentration from exceeding
allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information.
Excessive refrigerant in a closed ambient can lead to oxygen
deficiency.
•
If the refrigerant gas leaks during installation, ventilate the
area immediately.
Toxic gas may be produced if the refrigerant gas comes into
contact with fire.
•
After completing the installation work, check that the refriger-
ant gas does not leak.
Toxic gas may be produced if the refrigerant gas leaks into
the room and comes into contact with a source of fire, such
as a fan heater, stove or cooker.
•
Do not directly touch any refrigerant which has leaked out of
refrigerant piping connections, etc.
This may cause frostbite.
CAUTION
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in elec-
tric shocks or fire.
•
Install the indoor and outdoor units, power supply wiring and
connecting wires at least 1 meter away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient enough to eliminate the noise.)
•
While following the instructions in this installation manual,
install drain piping in order to ensure proper drainage and
insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and prop-
erty damage.
•
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.
Inproper duct work may cause electric shocks or fire.
•
Do not install the unit in the following locations:
a. Place subjected to high temperature or direct flame.
May result in fire or overheating.
b.
Where a mineral oil mist or an oil spray or vapor is pro-
duced, for example in a kitchen.
This may cause fire.
