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
customers that they should keep this installation manual along the
with user manual for future reference.
Be sure only trained and qualified service personnel
install, repair or do the maintenance of the equipment.
Improper installation, repair, and maintenance may result in
electric shocks, short-circuit, leaks, fire or other damage to
the equipment.
Install according to this installation instructions strictly.
If installation is defective, it will cause water leakage,
electrical shock and fire.
Disconnect the power supply before cleaning and
maintenance.
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 space can lead to
hypoxemia
(oxygen deficiency)
.
Use the attached accessories and specified parts
for
installation.
Otherwise, it will cause the set to fall, leak water,
produce electrical shocks and fire.
Install at a strong and firm location which is able to
withstand the equipment's weight.
If the strength is not enough or installation is not properly
done, the set will drop and cause injury.
The appliance should not be installed in a laundry.
Before obtaining access to terminals, all supply circuits
must be disconnected.
The appliance must be positioned so that the plug is
accessible
(
for European products
)
.
The enclosure of the appliance should be marked with
words or symbols with the direction of the fluid flow.
For electrical work, follow the local national wiring
standard, regulation and this installation instructions.
An independent circuit and outlet must be used.
If electrical circuit capacity is not enough or if the electrical
work is faulty, it will cause electrical shock fire.
Use the specified cable, connect tightly and clamp
it in a way that no external force can be acted on the
terminal.
If a connection or fixing is not perfect, it will cause the
appliance to heat-up or create a fire at the connection.
Wiring routing must be properly arranged so that control
board cover is fixed properly.
If the control board cover is not fixed properly, it will cause
heat-up at the connection point of the terminal, fire or
electrical shock.
If the supply cord is damaged, it must be replaced by the
manufacture, a service agent or a similarly qualified
person in order to avoid a hazard
(
for European
products
)
.
An all-pole disconnection switch with a contact
separation of at least 3 mm in all poles should be
connected in fixed wiring
(
for European products
).
When carrying out piping connection, take caution in not
letting air go inside the refrigeration cycle.
Otherwise, it will lower the capacity, cause abnormal high
pressure in the refrigeration cycle, explosion and injury.
Do not modify the length of the power supply cord or use
an extension cord, and do not share the single outlet
with other electrical appliances
(
for European products
)
.
Otherwise, it will cause a fire or an electrical shock.
Carry out the specified installation work after taking into
account strong winds, typhoons and earthquakes.
Improper installation work may result in the falling of the
equipment and in accidents.
If the refrigerant leaks during installation, ventilate the
area immediately.
Toxic gas may be produced if the refrigerant comes into
contact with fire.
