PRECAUTIONS
■ Ensure when installing National Regulations are complied with.
Failure to do so, could cause damage or injury.
■ Read "PRECAUTIONS" carefully before installation.
■ The following precautions include important safety items.
■ Keep this manual with the owner's manual for future reference.
The safety precautions listed here are divided into two categories. In
either case, important safety information is listed which must be read
carefully prior to installing or servicing.
Failure to observe a warning may result in injury.
Failure to observe a caution may result in injury or damage to
the equipment.
After completing the installation, make sure that the unit operates
properly during the start-up operation. Please instruct the customer
on how to operate the unit and keep it maintained.Also, inform cus-
tomers that they should store this installation manual along with the
owner's manual for future reference.
Only trained and qualified service personnel to install,
repair or service the equipment.
Incorrect installation, repair, and maintenance may result in
electric shocks, short-circuit, leaks, fire or other damage to
the equipment.

WARNING
CAUTION
WARNING
Install according to this installation instructions only.
If the installation is defective, it will cause water leakage, electrical
shock and fire.
When installing the unit in a small room, take measures against to
stop refrigerant concentration from exceeding allowable safety
limits in the event of refrigerant leakage.
Contact your installer immediately should this happen. Excessive
refrigerant in a closed ambient can lead to oxygen deficiency.
Use the enclosed parts and specified parts for installation,
Failure to do so could cause the set to fall, water leakage, electrical
shock fire.
If the wall is not sufficient to hold the units weight, this could cause
the unit to drop and result in injury.
The appliance must be installed 2.3 m above the floor.
The appliance shall not be installed in the laundry.
Before obtaining access to electrics, all supply circuits must be
disconnected.
For electrical work, follow the local national a separate electrical,
regulation and this installation manual. An independent circuit and
single outlet must be used.
If the electrical circuit capacity is not enough or defect in electrical
work, it will cause an electrical shock and fire.
Only use the specified cable and ensure the cable is connect tightly
and clamp the cable so that no external force will be acted on the
terminal.
If the connection or fixing is not perfect, it will cause heat-up or fire at
the connection.
Wiring routing must be properly arranged so that control board
cover is fixed properly.
If control board cover is not fixed perfectly, it will cause heat-up at
connection point of terminal, possibly causing a fire or electrical shock.
If the supply cord is damaged, it must be replaced by the
manufacture or its sevice agent or a similarly qualified person in
order to avoid a hazard.
An all-pole disconnection swith having a contact separation of at
least 3mm in all poles should be connected in fixed wiring.
When carrying out piping connection, take care not to let air
substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the
refrigeration cycle, explosion and injury.
Do not modify the length of the power supply cable or use of
extension cable, and do not share the single outlet with other
electrical appliances.
Otherwise, it will cause fire or electrical shock.
The temperture of refrigerant circuit will be high, please keep the
interconnection cable away from the copper tube.
