1 SAFETY SUMMARY
HITACHI cannot anticipate every possible circumstance that
might involve a potential hazard.
D A N G E R
•
Use the specified non-flammable refrigerant to the out-
door unit in the refrigerant cycle. Do not charge mate-
rial other than specified refrigerant into the unit such as
hydrocarbon refrigerants (propane or etc.), oxygen, flam-
mable 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, extin-
guish any naked flames and contact your service con-
tractor, 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.

Description
•
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.
•
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 en-
gineer is provided for electrical work to avoid an electri-
cal 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 bet-
ween units.
•
Other cables except the one provided as accessory can-
not be used. The electronic expansion valve may not ac-
tivate normally due to voltage fall.
•
After connecting to the expansion valve cable in the in-
door unit, secure it firmly with the cord clamp. Place the
wiring in space at the rear side of the indoor unit electri-
cal box to prevent generation of fire.
•
Fix the cables securely with the cord clamp. External for-
ces 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.
