1. PRECAUTIONS
Comply with local, national and international laws and
regulations.
Read "PRECAUTIONS" carefully before installation.
The following precautions include important safety items.
Strictly follow them.
Keep this manual with the owner's manual in a handy place
for future reference.
The safety precautions listed here are divided into two categories.
Read both carefully.
WARNING
Failure to observe a warning may result in death.
CAUTION
Failure to observe a caution may result in injury or
damage to the equipment.
After completing the installation, ensure that the unit operates
properly during start-up. 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 owner's manual for
future reference.
WARNING
Only qualified service personnel can install, repair, or
service the equipment.
Improper installation, repair, and maintenance may result in
electric shocks, short-circuit, leaks, fire or other damage to
the equipment.
Strictly perform installation according to these
PAGE
installation instructions.
Faulty installation may cause water leaks, electric shocks and
fires.
When installing the unit in a small room, take measures
to keep the 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 environment can
lead to oxygen deficiency.
Only use the attached accessories parts and specified
parts for installation.
Otherwise, the set may fall and cause water leaks, electric
shocks and fire.
Install at a strong and firm location that can bear the
set's weight.
If the installation area is not strong enough or installation is
not properly done, the set may fall and cause injury.
The appliance should not be installed in a laundry room.
Before obtaining access to terminals, all supply circuits
must be disconnected.
The appliance must be positioned so that the plug is
accessible.
The enclosure of the appliance must be marked by word
or symbols, including the direction of fluid flow.
For electrical work, follow the national wiring standards,
regulations, and these installation instructions. An
independent circuit and single outlet must be used.
If the electric circuit capacity is insufficient or electrical work
is defective, an electrical fire may result.
Use the specified cable, connect it tightly and clamp the
cable so that no external force will act on the terminal.
If connection or fixing is imperfect, over-heating or a fire at
the connection point may occur.
Wiring routing must be properly arranged so that the
control board cover is fixed properly.
If the control board cover is fixed imperfectly, it may cause
overheating at the connection point of the terminal, a fire, or
electric shocks.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or a similarly qualified
person to avoid a hazard.
A disconnection switch with at least 3mm separation
should be connected in the fixed wiring of all poles.
When connecting the pipes, do not let air get into the
refrigeration cycle.
Otherwise, it will lower capacity and may cause abnormally
high pressure in the refrigeration cycle, an 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.
Otherwise, it may cause a fire or electric shocks.
Carry out the specified installation work after
considering the possibility of strong winds, typhoons or
earthquakes.
Improper installation work may result in the equipment falling
and causing accidents.
