d a n g e r
•
Use the specified non-flammable refrigerant to the outdoor unit in
the refrigerant cycle. Do not charge material other than specified
refrigerant into the unit such as hydrocarbon refrigerants
(propane or etc.), oxygen, flammable gases (acetylene or etc.)
or poisonous gases when installing, maintaining and moving.
These flammables are extremely dangerous and may cause an
explosion, a fire, and injury.
•
Do not pour water into the indoor or outdoor unit. These
products are equipped with electrical parts. If poured, it will
cause a serious electrical shock.
•
Do not touch or adjust safety devices inside the indoor or
outdoor units. If these devices are touched or readjusted, it may
cause a serious accident.
•
Do not open the service cover or access panel for the indoor or
outdoor units without turning OFF the main power supply.
•
Refrigerant leakage can cause difficulty with breathing due to
insufficient air. Turn OFF the main switch, extinguish any naked
flames and contact your service contractor, if refrigerant leakage
occurs.
•
The installer and system specialist shall secure safety against
refrigerant leakage according to local regulations or standards.
•
Use an ELB (Electric Leakage Breaker). In the event of a fault,
there is danger of an electric shock or a fire if it is not used.
•
Do not install the outdoor unit where there is a high level of
oil mist, flammable gases, salty air or harmful gases such as
sulphur.
•
This product is designed for indoor installation only. Do not
install it outdoors.
•
Do not perform installation work without referring to this
Installation and Operation Manual. If the instructions are not
followed, it may result in a water leakage, electric shock or fire.
•
Secure the sufficiently strong foundation when installing. If not,
it may lead to falling of the unit and injury.
•
Do not install where generation or flowing of flammable gas may
be detected. It may cause a fire.
•
Do not step or put any material on the product.
•
When using refrigerant, wear leather gloves to prevent cold
injuries.

description
•
Check the refrigerant leakage. The refrigerant R410A is
incombustible, non-toxic and odorless of HFC gas. However, if
leakage occurs and gas fills a room, it may cause difficulty with
breathing due to insufficient air.
•
Ask the electrical shop where the qualified electrical engineer
is provided for electrical work to avoid an electrical shock and
fire disaster.
•
Perform electrical work according to Installation and Operation
Manual and use all relevant regulations and standards. If not, it
may cause an electrical shock or fire.
•
Use the accessory extension cable for the wiring between units.
•
Other cables except the one provided as accessory cannot be
used. The electronic expansion valve may not activate normally
due to voltage fall.
•
After connecting to the expansion valve cable in the indoor
unit, secure it firmly with the cord clamp. Place the wiring in
space at the rear side of the indoor unit electrical box to prevent
generation of fire.
•
Fix the cables securely with the cord clamp. External forces on
the connectors may lead to a fire.
•
Power supply is turned OFF before electrical wiring work or a
periodical check is performed.
•
Protect the wires and electrical parts from rats or other small
animals. If not, rats may gnaw at the unprotected parts and at the
worst, a fire may occur.
•
Place the expansion valve kit cable away from the power source
cable to avoid malfunction.
